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.

Drives were shipped promptly and received promptly. I installed in my NAS and RAID 5 initialized and installed with no bad sectors or smart errors. Happy with purchase

If you need a low-cost 3.5" SATA drive with a decent amount of storage but you're not performance conscious, this drive will fit the bill fine. I would have liked more storage, but once you go above 4TB, the price starts to go way up. This drive has the best value for storage space (at the time of this review). However, I wouldn't call this a robust drive. It feels quite light compared to some 6TB NAS drives I have used. However, for the price, if you just need some storage, I think this work fine for you.

"White Label" says it all: a "white label" and "as-is" disclaimer is a license-to-steal. "Probably" pulled from a server farm with "Relocated_Sector_Count" and "Power_On_Hours" reset to zero to hide age. Mine failed, after MUCH effort to reconfigure it as a longer-lived replacement for a smaller drive, after 10 months. After failing to boot, booting from a liveUSB, simply "looking" for the drive with lsblk proved it was "hopping around": first /dev/sdc, then sdd, then sde, the f, then g... AI says it's the controller electronics failing after a prior long life on the server farm.

Bought 5 of these end of 2021, had them in my Synology NAS. One of them had SMART critical warning on Sep 2022, still working by the time I see the warning. Emailed and processed a quick warranty replacement, down side is you have to pay for send it back, but turnaround time was less than a week, very quick, great service. For QNAP owners, when I had them tested in QNAP, it was unacceptable loud even when idle. Then I found out if you mount these drives with screws instead of using just quick snap mounts, they make much less noise because less vibration between drives and trays. For Synology there is no way to mount with screws(at lease my DS1621+), but somehow Synology managed to have less vibration using just quick snap mounts, no problem so far, other than full load, 5 drives are very quiet.

Works fine good price

Excellent refurbished drive. Plugged it into my NAS and it worked perfectly. Resilvered the pool and it has been working every since. Great price, fast boot, easy install, runs quietly, and so far - no lost data or uptime. Hopefully it stays reliable and durable for years to come.

I bought 5 of these in 2022. 4 are running in an array on one NAS. the 5th on a separate machine has failed. There was a defective controller chip on the controller board (bottom of the drive) that overheated badly enough for a total failure before I could get all of the data off. I noticed a 1 year warranty on the unit. That was a pleasant surprise as I figured a 90 day warranty. I never like failures, and I lost some data. If anything is going to fail on a piece of hardware like this, it is most likely to happen in the first 90 days. MDTech was very responsive on replacing this drive under warranty including sending a pre-paid shipping label for the return. Kudos to MD-Tech on their customer service and replacing this drive promptly. All is well. I'm happy with MD-Tech as a vendor.
