content: So my old external hard drive is undersized(500gb) generally it was not an issue, until the mobo on the laptop crapped out. Which left me with contemplating backing up a much larger hdd.What i'm looking forInterface: esata, usb 3.0(and up) or Thunderbolt3 connectivity.Size : it will mostly sit on/under a desk, or stored out of the way.Price: $250 and below, some leeway is thereCapacity: over 4tbNeeds to be reliable, internet access will not always be available.

content: I have four of these. The oldest is about 10 years old and all are working fine. The newest is about three years old so I can't really comment about the current model.https://www.newegg.com/rosewill-rx-358-u3c-blk/p/N82E16817182247WD Reds are $115 and often go on sale for less (the 4TGB 5400rpm model).https://www.newegg.com/red-wd40efrx-4tb/p/N82E16822236599However, for 4TB you might want to consider some kind of NAS setup instead.

content: Whatever you do, please don't rely on a single hard drive to back up all your data. At least make two copies, verify them often and at the first sign of trouble, look at a replacement.

content: Quote from: Vgkid on February 19, 2020, 08:11:52 amDepends on how computer literate you are, a box with a big SATA HBA running FreeBSD (not FreeNAS, though that works too), is what I use. Check out SFTP as a solution for data shares, as it offers random access data via SSH (meaning it's secure over WAN), is quite easy to setup, and has acceptable throughput on even slower machines. That being said, I have heard issues with files corrupting if multiple people write to it at once, so do your homework.I get all of my drives from goHardDrive, they sell refurb HGST UltraStars for next to nothing (4TB drives are around 60USD last I checked, also check Newegg, they have some stuff up there for different prices and stock), and they are nice, reliable drives for the average Joe. I've got a 2TB one that's been in service for around 6 years, 24/7, and it's still kicking.

content: A vote for FreeNAS here. If you have decent basic computer knowledge, FreeNAS is good option. It's very flexible, you can go really cheap and small, really expensive and big, or anywhere in between.I have a small, sort of cheap, but pretty good FreeNAS setup.FreeNAS 9.10.2-U6HP N54L Microserver Gen 72x 4 GB Crucial ECC DDR32x 16 GB Sandisk Cruzer Fit (OS - mirrored)1x 8 GB Generic USB flash drive (System dataset)2x 2 TB Blue WD20EZRZ (Data - mirrored)2x 4 TB Red WD40EFRX (Data - mirrored)

content: Quote from: Vgkid on February 18, 2020, 06:29:45 amI suggest upping the budget and installing a NAS.At home I use WD black drives exclusively, because of the 5 year warranty. Haven't had one of these fail on me.For external enclosures I use Synology boxes. I still have a Synology DS106 working, and it must be ~13 years old. I'm about it replace it with a DS218.

content: Quote from: thermistor-guy on February 21, 2020, 02:14:39 amI am retiring my WD Black drives because one failed a couple weeks ago. I would not use WD Black drives in a RAID configuration because they have not supported limited error recovery time since about 2010 when Western Digital updated their firmware to remove this function. They were replaced by the RE series of drives in RAID applications.

content: I have a Netgear ReadyNAS 104 for about 5 years and ticking quite alright. It is furnished with four WD 3TB green hard drives.It is mostly used for backup, thus it is not heavily loaded, but it has constant newer firmware releases.

content: To a certain degree, it doesn't really matter what drives you use with FreeNAS, but the WD Reds were specifically made for NAS use and seem to have a pretty good reputation.I have a WD Black 1TB (one of four I own) and a 150GB Raptor that are 11 years old, but I haven't actually used the 1TB in about a year. The Raptor is still a daily driver, though that'll be coming to an end soon.

content: The NAS route is looking good, will probable go with a Synology box. Are these things ok to run over a wifi network? Don't mind upgrading thatRegarding hdd speeds then, is the 5.9k or 7.2k make a difference?

content: connecting to a nas over wifi will take 10x longer to transfert the files, but will work the same.I always connected the nas to the wired part of the network. then clients can be over wifi if needed.

content: Quote from: David Hess on February 21, 2020, 02:37:17 amDo not use consumer grade drives on proper hardware RAID controllers period. It's likely to end in tears. TLER (and other names) can cause problems with proper RAID depending on how it's set. Essentially the disk tries to do error correction and ignores certain ATA commands for a period (usually set by the manufacturer). Some RAID controllers interpret this as a failed disk and will kick it out of the array. There are some drives where you can adjust or disable this timeout (as in it will fail immediately), but for many, you can't.If you're using consumer disks, you are far better off with something like ZFS (even with enterprise drives, ZFS offers advantages over traditional RAID).At the end of the day, all drives will fail. I'm on about my 9th year using my 2TB Hitachi Ultrastar drives and whilst they are still working perfectly fine, they are starting to reach the limit of their serviceable life (considering they've been spinning for 99.9% of the past 9 years). I have redundancy in place on another server should the entire thing fall over tomorrow.

content: I once imported two Rosewill enclosures to clean up some mess but it turned out to be a big mistake.I think they were these:https://www.newegg.com/rosewill-rx304-apu3-35b/p/N82E16817182316I used my own power supplies as they were a different plug and I know the LiShin 4 - 5 amps ones I use work well with many spares, The drives were in single not raid and it was fine initially.The enclosures were on a shelf untouched but they both failed. The screen broke on one and intermittently worked and the sata port on the other stopped working a couple of months later.In the end I used a 4 drive enclosure casing from an atx case that already had a fan attached to it and wired up to an atx power supply that which were all on shelves, put in a 1m esata to sata cable to the esata card and I had no problems after that and I tied everything down in such a way that the cables couldn't fall out on movement.

content: Quote from: nctnico on February 20, 2020, 11:05:54 pmOn the subject of rsync & backups, you might also be interested in rsnapshot. Basically it makes an LVM based temp snapshot of volume being backed up, and then performs an rsync on that snapshot. That way there are no problems if a file is being modified while the backup is still running. The backup will based on the files as they exist at the moment of snapshot. It's lightweight, and Just Works .

content: Quote from: Halcyon on February 21, 2020, 11:15:16 amThe point of TLER is to prevent problems with RAID, hardware or software, when the RAID is in a better position to recover the data because it has another copy. For instance a bad sector can be rewritten forcing the drive to reallocate it instead of kicking the drive from the RAID when it times out trying to recover it.In none RAID applications, TLER just gets in the way when you want the drive to make every effort to recover a bad sector.

content: Quote from: gabinetex on February 18, 2020, 11:57:25 amSome people said they were, but they seem to put in whatever they have spare. The vast majority of them turned out to be WD white drives, and none of them were He drives- just regular non-sealed air drives for the 8TB models.Even the ones that had the HGST drives, as it turned out, didn't have the tighter HGST manufacturing specs. They even slowed down the drives to meet the longevity and cost goals. It sucks because Hitachi (HGST) drives have been my go-to products for years.Everything is still up in the air after the acquisition. Will they just use the lower-performing drives in external enclosures, and send the better ones for internal drives? (Manufacturers have done this for years.) All of their weird actions lately have me worried about HGST. But, as always with drives, it's all just speculation. We won't really know the real data until they have been out for a few years... at which point the data is of limited use because models are generally replaced or otherwise unavailable by then.That being said, even the lower-tier drives have been doing well as far as longevity goes, so it might not matter all that much, especially if you're doing just a few drives. Even with quite poor drives, 75% of them will be functional after a few years.Also, what Halcyon said is correct about RAID and consumer drives. It's unfortunate because it's forced- there no real reason, other than them wanting to charge more for the firmware capability. But you can still just use full backups with non-RAID drives, for example.
