White Label WL 4TB 7200RPM 64MB Cache SATA 6.0Gb/s (Enterprise Grade) 3.5" Hard Drive (for Server, RAID, NAS, DVR, Desktop PC)

3 Year Update - 32644 hours on these drives & smart data says drives are still in good health!I've purchased 8 of these drives at various times and at various prices in last 3 years and have yet to see a failure (surprisingly). 4 of them are in my NAS system running 24/7. The other 4 I keep on hand for spares or migrations/expansions. To be honest, I was expecting more problems when I purchased them or for them to be discontinued (hence the extra's) but ya, they're great... and still sold 3 years later... so the honest truth is these are awesome drives at rock bottom prices and I fully plan on purchasing more. This is the best kept secret. I didn't want to leave this review because I wanted to keep it that way but its the right thing to do so you're welcome.More details:- As far as I can tell, they are new drives, not renewed. They all came packaged well and unopened.- They get the expected 170 MBps seq read/write for a 7200 RPM drive.- They do get toasty if left unchecked, however I run them in a well ventilated enclosure in a cold basement so I don't have any thermal issues.- Despite having a White-Label, doing a deeper dive shows that all the drives I got are actually HGST. Some of them literally have HGST model number in the stats (see bottom one in the screenshot), but the firmware running on the others leads me to believe that they are also HGST/Western Digital. Because these are White-Label tho, nothing is certain.- A few of the drives are only rated at SATA II despite saying SATA III on the page. Really tho - that doesnt matter. A hard disk can never SATA III speeds anyways. Just an oddity I noticed.

Works as it should. A A A + + +

Returned for full refund when, upon receipt, I tested it. The self test could not complete; it hung with 80% left to do. See screenshot of what smartctl was able to glean from the disk. The disk's error log contained a DMA error at 65,242 power-on hours. The number of power-on hours was 6, so the odometer had been, er, adjusted before the disk was sent to me. See the label: the disk's serial number is nowhere to be found. A close reading of the smartctl output on the screenshot shows the hack of the disk's firmware was pretty clumsy. I wonder whether the now-hacked firmware, which can't pass its own tests and so can't report on its own authenticity, contains a security exploit. The more I think about this disk, the less I want to give DBSky any more of my business.

NAS reports 22k+ hours and zero problems. Good value for the money. I do wish it was a little quieter when writing to it though

I ordered one at first as I was very skeptical, 4TB for under 70 bucks? I received the drive quickly (same day) it was packaged as well as any other drive that I have received, in fact, it was packed in a Western Digital hard drive box that appeared to be turned the wrong side out, never the less it was packed very well inside hard drive caddies and inside an antistatic bag.Slipped the drive into my HD doc it was immediately recognized and was ready for formatting, incidentally, it showed up as a Hitachi brand drive and the full 4TB is available. since it is a Hitachi I figured I would order another, therefore I have 2 of these in my Media storage docks, which is currently at about 26TB give or take a couple of GB.These drives are 7200 RPM, my concern is that will "spin" themselves into an earlier grave than my WD Green and Red drives that I have (5400 RPM), it may be me, but they seem to run a smidge warmer than the others, they are quiet, and seem to be very stable, no vibration or anything (I tested reading and writing several GB on each)For the price, even if they fail in a year it was worth the gamble, (for me, the Data can be replaced, I don't run backups or any kind of redundancy) and at 69.95 for 4 TB its a smoking deal!

I bought this to replace a failing 2TB external drive I use exclusively for local backups, and to test to see if these are good candidates for replacing my IronWolf's in my RAID5 array on my SOHO server (when they fail).It's been about 2 weeks, and it's working fine so far. I did a full dd wipe before mounting, and no errors or bad sectors. However, I found it odd that in smartmontools, the drive doesn't report '187 - Reported Uncorrectable' or '188 - Command Timeout' stats, which are 2 of the 5 attributes I monitor (per Backblaze) to indicate pending failure.At half the price, I could replace these twice as often as the IronWolf's and still come out even. But without the stats, I feel like I'm half in-the-dark about drive health. So... still undecided.

These things get so hot they must be relabeled (refurbished?) Seagate drives. They literally get too hot to touch.

Didn’t realize 4TB would hold so much information. Holds everything I have with plenty of room for the future. A little loud but no problem for my situation.
