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

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

Works fine good price

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.

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.

The white label hard drive was received in a plain brown envelope with no protection whatsoever. The drive was dead, either killed in transit or shipped defective in the first place. Initiated a refund that was 'denied due to item not being in original condition'. Beware of this scam.

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.

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.

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.
