Nah dude, you can't compare two totally different cards this way.

But hey, I happen to have SKTools and a bunch of SanDisk cards, so I'll run some benchmarks. I only have two cards with me, so here are the preliminary results (type card : write / read):

Sandisk 4 GB Class 2 : 1875 / 5642

Sandisk 16 GB Class 2 : 922 / 6289

I've got bunch of 8 GB cards at home, class 2, 4 and 6 - it'll be interesting to see how they compare. I'll add the benchmarks when I get home this evening. For now, I think it's safe to say the class will only affect the speeds used when plugged into the computer, and not so much when inserted into the HD2.
[HD2 General] chribruu:
It's worth mentioning to those who don't know it, the class only refers to the MINIMUM transfer rate the card is capable of. It's sort of covered already in the thread, but not clearly. So a class 6 card have to support 6MB/sec minimum. If it has a write speed of 100MB/sec (exaggerating to underline the point) it would still be a class 6 card after todays specifications.
[HD2 General] dugald5:
I have a class 6 and I find that I can copy files onto the phone a great deal faster with this than I could with my previous class 2 card. The hardware is perfectly capable of reading at the higher speeds, and yes some things are therefore faster - copying large files, loading large programs and accessing large map files for route planning.

Anyone that thinks manufacturers would say a card is class2 when it can actually read at class4 or class6 speeds is kidding themself.

Yes some operations do not require such high read/write speeds, but that is like saying a car that can do 30mph is sufficient because that is all you need around town - often you will find yourself on the highway chugging along like an OAP at half the speed you could be doing.
[HD2 General] Shasarak:
No. Classes are about minimum write speed, and read speed is usually higher.

http://en.wikipedia.org/wiki/Secure_Digital#SD_Speed_Class_Ratings

I've seen a class 2 Sandisk card benchmark at comfortably over 9MB/s read speed. My class 6 Sandisk card benchmarks at around 15/18 MB/s (write/read).
[HD2 General] Appelsap:
Look peeps, I think it is pointless to keep posting stuff like "I think ...", "I find ..." or "I've seen ...". It is all based on what people think and/or feel they have experienced, and doesn't prove anything. The argument will just go back and forth between different the 'believers'.

If we want to *KNOW* if there is a significant difference, we need actual facts - not opinions, thoughts or personal experiences.
[HD2 General] Xeon:
Can someone confirm that it also depends on the file system the card uses and the cluster size ? I find 32K really good for average files.
[HD2 General] franck2218:
So, witch cards we need ? :confused:
[HD2 General] dugald5:
I have not used benchmarking software, as I just don't have time. However, if I am copying a large file to my HD2 in Windows 7 or Ubuntu it tells me the transfer speed. With my class6 it hovers arround 5.5 mb/sec and with my class 2 it was around 2 mb/sec.
[HD2 General] Appelsap:
Ok folks, I'm home and did some tests. What I think the question here is: is there a difference in everyday use - ie does the HD2 work faster with a more expensive card? To answer that, I've benchmarked with sktools.

Main storage, I get : 5441 write / 31000 - 56000 read speed (KB/s)

(read data from main mem varies a lot)

Sandisk 8 GB class 2 FAT32 - cluster size 32 KB : 729 / 6367 KB/s

Sandisk 8 GB class 4 FAT32 - cluster size 32 KB : 2684 / 7111 KB/s

Sandisk 8 GB class 6 FAT32 - cluster size 4 KB : 1172 / 7062 KB/s

Sandisk 8 GB class 6 FAT32 - cluster size 32 KB : 2661 / 7062 KB/s

Sandisk 16 GB class 2 FAT32 - cluster size 8KB : 922 / 6289 KB/s

Sandisk 16 GB class 2 FAT32 - cluster size 32KB : 1226 / 6308 KB/s

I think it's fair to say the class can affect write speed on the HD2. Looking at the 8BG cards I tested, you can tell that you might get lucky with lower rated cards (as I did, my class 4 card outperforms the class 6), but will be sure with the higher class. Note that both the class 4 & 6 have over three times better write speeds than the class 2 does.

As for read speeds, my guess is the HD2 is the limiting factor here, all the values are too close - there isn't a truly significant difference.

Most people don't write that much on the card when using the HD2 - it's mostly about reading. Because the read speeds are so similar, I'd say the only reason to spend more money on higher classed cards would be spent well if you transfer files to it a lot and you want to be sure you get the higher speed. In all other cases, stick with the class 2, you'll be fine I guess.

Oh, and btw, I get an avg write speed of 7.5 MB/s with the 16BG class 2 card in the cardreader. Fast enough for me.
[HD2 General] tboy2000:
What is the optimum cluster size to use when formatting the card?
[HD2 General] Xeon:
I'd love to know the performance of the 16GB class2 with cluster size 64K vs 32K vs 16K vs 8K.

As I know, smaller cluster size is useful if you have too many small files whereas 32KB and above is good for larger files ( 10MB+ )

Correct me if Im wrong.

And what's the difference between Sandisk 8GB micro SD class2 and Sandisk 8GB micro SDHC class2 ?? what does High Capacity change ?
[HD2 General] Agoattamer:
Appelsap's numbers were probably correct. The class of the card has NOTHING to do with the read speed of the card. It is only for the write speed. Class 2-2MB/s, 4-4MB/s, 6-6MB/s. Read speed is usually determined by the quality of the card and the device reading it. Read speed of the card is usually way higher than what the device can read it at. That is why specs are usually not given for read speed.

So once you have a 16gb card filled up it wont matter if its class 2 or class 6. Performance will be the same for reading from it. A class 6 card will only be useful if transferring large files at a time to the card.

testing

I'm going to test it out right now. someone else thought they had it also but the rom was messed up. ill give it a shot thank you for posting. i flashed my phone and so far all roms either use manilla which i don't like or have serious battery issues. ill post the results
[Touch Diamond2, Pure ROM Development] b14ck_h4wk:
Sticky this thread

ok flashed twice no problems getting to the settings after changing the item/theme, but the issue i am having is that its not showing me how many bars of service i have. sometimes it will appear for a quick second and go away again. im going to re download tomorrow and flash it again and post results.

either way this needs to be sticky !!
[Touch Diamond2, Pure ROM Development] DaveNavy:
WOW That's Odd that your having this issue because I'm currently using this ROM on my Pure because I wanted to return to stock, and I haven't had any issues at all, My battery actually has improved and also I have noticed a great improvement in sound quality of media and ringtones.

Hope you get everything sorted out,...Im no pro but I did Clear Storage , remove my sim and SD card from the Device and Entered into Bootmode before I Updated to this ROM And I'm using 3.45.25.22 Radio for at&t and all seems to be well.
[Touch Diamond2, Pure ROM Development] jcamacho14:
Can this ROM be used on an Unlocked TD2?
[Touch Diamond2, Pure ROM Development] DaveNavy:
Im Not Sure

I'm not sure because I thought the TD2 is already unlocked, isn't it a non carrier branded device?

not sure....But you do know this is the ROM for the AT&T pure right?

Phone has Same internal Stuff but Different outer shell and Carrier Branded Software....But no trial crap.

I don't know about unlocking because I haven't unlocked my device yet.
[Touch Diamond2, Pure ROM Development] player911:
@b14ck_h4wk: The newer rom builds have fixed the battery issues. It was a bug in several of the previous releases.

@jcamacho14: TD2 and Pure are the same device. This ROM is very custom to AT&T network and may not work properly with other carriers. This is not an official rom since it requires CustomRUU to flash

@DaveNavy: The TD2 can be bought unbranded and unlocked, or branded and locked via a Carrier. Depends. You can flash new roms without "unlocking" it. You just have to first flash with "HardSPL" which allows unofficial software to be flashed to your device.

I thought we already had reconstructed ROM dump of the AT&T WarHawk (Pure aka Diamond 2).
[Touch Diamond2, Pure ROM Development] jcamacho14:
Yes, my device is non-carrier branded.

The thing is that my carrier are currently using the 850Mhz 3G Band, and the unlocked version only have 900/2100.

As I understand this a hardware issue, but I just wanted to test it with the software of the Pure which have the 850 band... Just to confimr by myself :D

Thanks....
[Touch Diamond2, Pure ROM Development] jcamacho14:
Thanks again player911... :p
[Touch Diamond2, Pure ROM Development] DaveNavy:
This Is Official Its The Signed RUU ROM

This is not a "Reconstructed" ROM if you read the post,...This is a Signed RUU

It is the an Official NBH of the "AT&T BRANDED PURE" sorry about using custom RUU but thats tho only way I know how to Flash a stand alone NBH to a device,...

The Reconstructed ROMS have Issues by the way,...Because the cooks wanted to add one or two little improvements that caused errors on their reconstructed versions,...for example MMS settings not being present on the handset, or LPCUST not working and a few others not to mention like media net not connecting like it should to update the weather,....

THIS NBH is really UNTOUCHED,...If you really want a stock version this is the way to go.

Not to sound like a jerk to the Senior member who answered all our questions

for us....But don't you think testing a ROM or Reading the NBH to see if it is Official or not is more appropriate before posting anything?,...This was not easy to get by any means!!! TRUST ME I WENT THREW ALOT TO GET IT.

I understand its being flashed with Custom RUU ...

But in the same token it is also a Signed RUU .NBH

P.S. TD2 and Warhawk Are in the Same Device Family However The Small changes cosmetically as well as in the hardware and software do make them a different device, Okay Has same Logic Board and chipset but wvga drivers are not the same and many differences between the two. No front facing camera,...and using TD2 software on the diamond shows when you press the video call button in the dialer,...It crashes. Also Terrible issues with Landscaping module.

In my experience using a TD2 Based ROM on my PURE/Warhawk I get bad battery life, Overheating from wi-fi use and GPS use,...as well as internet tether. Maybe thats just me but Im glad I have the ROM intended for my device back on it....its fast dependable battery life is great.
[Touch Diamond2, Pure ROM Development] b14ck_h4wk:
well in your opinion whats the best non manilla rom with no battery issues?

and also i re downloaded the rom flashed a few more times and still no luck with the 3g signal bars they would still flash 4 bars once in awhile but i could make calls browse the web fine it was just the picture of the bars giving me issues. and then actually about 4hours later they came on and stayed there.
[Touch Diamond2, Pure ROM Development] Pisca:
Just for your information, Ruu_Signed.nhb is the file name for any ROM produced at any kitchen, all of them are named like that, doesn't matter the kitchen used, as well as the ones included in the official roms
[Touch Diamond2, Pure ROM Development] DaveNavy:
okay if this rom is not an untouched original then i will never post on here again....thats my promise.
[Touch Diamond2, Pure ROM Development] b14ck_h4wk:
he did take out the trial software so it actually is partially modified....
[Touch Diamond2, Pure ROM Development] solmnc:
Based on the ROM and CE OS version numbers, this was probably a pre-release build of the ROM. I haven't done any flashing to my Pure yet, and after a hard reset, the actual shipped ROM and CE versions are as follows:

ROM version: 2.31.502.4 (66023) WWE

(D 2.31.66023 during bootup)

ROM date: 09/18/09

CE OS 5.2.21849 (Build 21849.5.0.63)

So while it may be an AT&T ROM, it's definitely not the one that was shipped with the Pure unfortunately.

[Touch Diamond2, Pure ROM Development] solmnc:
From what I've gathered from the last few days of researching, there are some minor bugs with the rebuilg and more importantly, it's unsigned. It doesn't seem like there's a way to completely revert the Pure back to stock form quite yet.

No flashing for me until there is unfortunately...
[Touch Diamond2, Pure ROM Development] naplesbill:
I flashed this rom and it seems to work perfectly except for one thing. I cannot update the stocks using data. It will only update when I'm connected to wifi. All other programs work with data though.
[Touch Diamond2, Pure ROM Development] DaveNavy:
UNTOUCHED!

Like I Said Untouched,....It doesnt Have Trial Version Software Because it is

a 2.06 ROM and Its not 2.31 With all the trial crap because I work for a unnamed US phone carrier aka the deathstar and I received my Pure for testing at the beginning of august so I have had mine for a couple months before you guys got yours,...So naturally my ROM is the Original WARHAWK 2.06 ROM

and after the trial crap was loaded to the device and was on the market for the general public as the "PURE"....Then it shipped with 2.31,....

This is however an original PURE/WARHAWK ROM Just not the One Shipped to the General Public On The Retail Release Date.
[Touch Diamond2, Pure ROM Development] DaveNavy:
fix for that is as follows,....go to data connection and select setup

selected advanced,....select networks.....and on second scroll bar that says

Programs that automatically connect to a private network should connect using:

Change this from my ISP to MEdia Net and hit okay,...Then You will be able to update your stocks correctly.
[Touch Diamond2, Pure ROM Development] DaveNavy:
Anbody else want to challenge the validility of my claim?

I see it pointless to keep arguing the point flash it if you want.

test it out and see

all up to you....Like I Said it is Official and shipped

Just not to the general public.
[Touch Diamond2, Pure ROM Development] naplesbill:
Thanks for the info. Now it is working perfectly. Thank you for sharing this with the rest of us. I'm glad to have the original dialer back. Now I can use the phone without holding it away from my cheek for fear of pressing buttons by accident. :)
[Touch Diamond2, Pure ROM Development] supertrac:
damn people should appreciate you instead of *****ing about. If they want the official rom then just get it from beegee's server, he has one. I got mine from his.

Yours is actually better than the one I have so I plan to extract and customize it in my kitchen tonight when i got home. Thanks bro.
[Touch Diamond2, Pure ROM Development] DaveNavy:
No Problem,...Only Trying to Help out.
[Touch Diamond2, Pure ROM Development] punkcell:
flash it lastnight works great thanks.
[Touch Diamond2, Pure ROM Development] DaveNavy:
pre-release yes and shipped with mine yes
[Touch Diamond2, Pure ROM Development] NBP Pipsquack Bird:
I think folks are talking about the meaning of terms - such as signed, custom, pre-release, etc.

But a discussion of terminology might be missing the forest for all the trees?

If I understand correctly, this guy is (says he is) an AT&T employee who has posted the stock AT&T Pure ROM which was rolled out to AT&T employees for field testing right before AT&T added in all the marketing bloatware to wrap and package to the public sales shelves.

If the real deal, surely this ROM would be extremely valuable and appreciated!
[Touch Diamond2, Pure ROM Development] DaveNavy:
You Got it buddy couldn't have better explained it myself.
[Touch Diamond2, Pure ROM Development] BigwaveMx:
tested and works nice. Looks exactly like the OEM. Thanks.
[Touch Diamond2, Pure ROM Development] drtolson:
Does this version have the MediaNet connection pre-defined for data, etc.?

Reason I'm asking is that I had a Pure directly from AT&T and I couldn't get rid of the MediaNet connection. Here in Canada on Rogers, I need a different set up, so I need to be able to remove the MediaNet connection.

Otherwise, I quite liked the AT&T ROM, especially if I could get it without the bloatware!:D

Thanks for any assistance. I'm new to the TOPAZ (recently from Raphael).
[Touch Diamond2, Pure ROM Development] DaveNavy:
media Net is Preloaded it is stock And Cannot Be Altered itself But You Can Create Another Connection and Use that one for how the phone connects to the internet and connect to the carrier of your choice. Just have to enter the connection data manually.
[Touch Diamond2, Pure ROM Development] naplesbill:
There is one issue I have found that I'd like to resolve. The WiFi app to configure the phone for ATT HotSpots seems to be missing. The only way I have found to get it installed is through the ATT MediaMall which will not work. It keeps returning an error that the phone number parameter is required [150]. Does anyone know how I can get the ATT WiFi app so I can access my free hotspots?
[Touch Diamond2, Pure ROM Development] ceo.mtcl:
Thanks a lot man! I am flashing it right now. I will post how it goes!
[Touch Diamond2, Pure ROM Development] DaveNavy:

[Touch Diamond2, Pure ROM Development] DaveNavy:

[Touch Diamond2, Pure ROM Development] jromeo350:
do you need to have hardspl installed for this to work since its a custom rom? and if you do, is there any way to find something for a bricked, stock, at&t pure? this is my post.. http://xdaforums.com/showthread.php?p=5183991#post5183991
[Touch Diamond2, Pure ROM Development] DaveNavy:
I sent a reply to your original post.
[Touch Diamond2, Pure ROM Development] drtolson:
OK, I have this working now on Rogers here in Canada. In addition to configuring a new modem connection for Rogers and re-pointing 'applications accessing the Internet' to use it instead of MediaNet, I also had to run the 'Disable Proxy' application found in the All Programs list. [It appears there is some hidden proxy setting somewhere that this will disable for you].

Everything seems to be working OK now. But I'll be doing more checking. Have to say that I prefer the AT&T interface structure to the one provided on the stock HTC 6.5 ROM.
[Touch Diamond2, Pure ROM Development] solmnc:
Has anyone tried flashing this with the original 1.83 SPL?

Without a doubt, NavyDave's efforts are greatly appreciated to provide a version of AT&T ROM. However, I'd recommend changing the title of this thread to more accurately represent this ROM by removing the words "shipped" and "stock." Had I not done further research, I would've voided my warranty with no way of returning it back to stock form as I almost started flashing my phone when I saw this. Also, it appears that the official hotfixes for the Pure on HTC's site will brick your phone if you use any ROM build other than the original 2.31.502.3 (66023) ROM.
[Touch Diamond2, Pure ROM Development] drtolson:
I haven't tried the hotfixes yet on this ROM. Did you or someone else try them and brick your phone?

Personally, I'm not having problems with intermittent SMS, but it would be neat to see if the Caller ID worked here in Canada.
[Touch Diamond2, Pure ROM Development] illocano:
Thanks for the ROM, I've had it for a week now and it works great. I was frustrated over the battery drain on the custom ROMs and wanted to go back to a stock one. There's still traces of the bloatware but its a minor issue. I don't think my shipped ROM had MS Voice Command but this ROM does; big plus!!!

Can you post other than Rapidshare? Rapidshare is getting greedy and not even allowing Free downloads most of the times nowadays.

Can you give some idea of what is the difference between the 2.06 and 2.31?

Thanks!!!!
[Touch Diamond2, Pure ROM Development] DaveNavy:
This is the second Time I Have flagged your post, He needs a new link for the official .nbh 2.06 Warhawk ROM not your 2.31 Dump, You know this already and you still persist on trying to build up rapid points by posting irrelevant links, Like I said this is the second time I have reported this on this thread alone and Admin has already removed it once, Im sure they have a record of it, You have been reported again.
[Touch Diamond2, Pure ROM Development] DaveNavy:
Yes I will Put it on Megaupload and a few others and post the links shortly.

2.06 is the Pre-shipped ROM That was At&t Branded for the Device Before At&t Marketing Changed the Name And Added The Bloat, It was the Original ROM Prior To Public Release, And Has Some other Features That the 2.31 ROM DUMP does not have Like for instance the 2.31 ROM DUMP has a LSCUSTAPP.exe Error when you select settings from the windows menu it crashes saying LSCustapp has an error or is not installed on the device, So the Dump has some errors,(2.31 DUMP also doesn't have the MMS settings to send picture messaging pre-configured so if you don't know your way around this phones system you may not be able to configure that on your own and well that means no picture messaging.

On the 2.06 Warhawk The games are intact but can be erased from the device in the remove apps section, saduko by its self, and the other games are all in a game pack that can be uninstalled to free up memory leaving Solitare Teeter and bubble breaker on the device because they are HTC Stock,...Butms. packman ferrari GT Diner Dash,Monoply, Collaps Chaos will all be removed after uninstalling.

So as far as speed, stability, battery,and Memory I believe 2.06.NBH blows the 2.31 DUMP out of the Water!!!!
[Touch Diamond2, Pure ROM Development] chikoo:
Thanks Dave.

If I have this ROM, will I be able to apply official updates released for the ATT Pure?
[Touch Diamond2, Pure ROM Development] DaveNavy:
No, Doesnt work I tried it, But the Caller ID and SMS issue That requires the hotfixes is not present on the 2.06 ROM only 2.31 needs the hotfixes so No the hot fixes will not install,...But in the same note this ROM version doesn't need them.
