Question: im building WHS 2011 server with Drive Bender software, is this compatible with 4 or 5 TB HDD? im planning to install 8x 5TB hdd.
Document: Picked this up when I recently rebuilt my WHS 2011 box, setup 4 2Tb Samsung drives in a raid 5 array, has worked well other that one instance that windows reported the array was completely full when it actually had almost nothing  on it, rebooting the server fixed the problem and it hasn't happened again.
I used this card in a budget Windows Home Server 2011 build. WHS2011 required some fennagalling to get the product and software working properly. (The default security settings for WHS Internet Explorer will not allow access to the "LocalHost:####" port. I resolved this by installing Firefox for the web access maintenance. )The RAID card itself works exceptionally well and I haven't had any issues.
This product works very well on my server machine.so far, no problem. just wish better access speed.very nice for this price range.The driver and soft came with this package did not work on WHS 2011 but newer ver. of driver on their website works fine.
This is the best bang for your buck for a cheap RAID-5 setup. It is very stable on my WHS 2011 with my 8TB RAID-5 array (5x2TB). Array rebuilds take about 6 hours and atto disk bench gets around 350-400MB/s. The RAID management interface is easy to setup & simple to use.
This card is really small in size. This adapter is best used to host an array to store data on, perhaps install software on. I don't recommend this adapter to host a boot drive. For boot drives, you are best off using a stand-alone drive on a separate adapter or perhaps a mirrored volume on a separate adapter (preferably SSD drives).The main negative issue I have with the adapter is that the BIOS setup is very incomplete.
Does not work. I had 6 2TB and 2 1.5TB drive connected to the card. At boot up, it does not see 2 of the 2TB HDs on port 0 and 1. As a test, I configured the 4x2TB drives into RAID 5 and 2x1.5TB drives int RAID0. While trying to transfer some files to the RAID5 logical drive, the RAID0 logical drive got disconnected and the 2x1.5TB drives dropped off the controller. Sending this piece of junk back and sticking with my old LSI.
If you are using SATA drives make sure you buy a (SFF-8087) SATA Breakout cable, it isn't included.Build a Raid 5 array, a couple of days later two of 4 drives refused to initialized after Windows 7 took and update and rebooted.Was able to fix by rebuilding the array and not deleting existing data. Have not had a problem with it since then.Nice to have all my digital movies in one place and on one drive.
8-port 6Gb/s PCI-E x16 RAID for under $200 is a steal! Sounds too good to be true really, but there are a lot of positive reviews out there so it seemed a sensible purchase. Very happy thus far.It's currently configured as a 4-disk RAID 5 with 1 spare, and will serve as a general storage server for several workstations. The 3 remaining channels will be used for expansion, as needed.
I've been using the RocketRAID 2720SGL in my Ubuntu home server for almost a year now (purchased Jan. 2013). I started with a software RAID 5 using MDADM, with four WD Red 3TB drives. I've since installed four more drives, growing the same array to a complete 8 drives.I'm now looking into getting a second of these since the price is simply unbelievable.
I purchased this adapter to install four 2TB drives for use with a HYPER-V 2008 R2 server I'm running at home. It has performed adequately so far. The drives are configured as a RAID 5 array. I plan to add another four drives as a separate array in the future. Note that you must buy the special breakout cables for this adapter as it supports SAS and SATA.
Answer: I've heard of people using 4TB.  I would guess 5TB drives would work also.
