New purchases Aug 2026 ~~~~~~~~~~~~~~~~~~~~ I purchased 2 more of these 8TB WD Red drives. One works perfectly. The other was DOA. Over the years I've bought numerous amounts of these WD Red drives and this was my very first DOA. However, giving Western Digital credit where it's due... I called Support yday. Got to speak to someone within about 60 seconds. Asian lady was very helpful and after explaining I'd tried the drive on 3 different systems (2 x Windows, 1 x Linux) and I could tell the drive was not even spinning up, she agreed the drive was defective and offered a Standard or Upgrade replacement. Standard... You return it, once received, a replacement is sent out within 7-10 business days Upgrade... You pay $25 (non-refundable) and they send you a new one immediately. They also keep your credit card on file and if you don't return the defect, they charge you accordingly. I opted for Standard as I'm in no immediate hurry so why pay $25. Within 10 minutes I received various emails noting my case number, registering the warranty, and finally she sent me a prepaid UPS label to return. The replacement is a certified (not new) drive. However its warranty starts now, meaning it has a 3 yr full warranty just like the NIB I purchased. At first I was kind of miffed about it but the more I thought about it, who cares... Drives generally either fail within a short space of time or they run for years. Having built many computers (personal and working for companies) and also having worked in the support side myself for manufacturers for years, I stand by my own past experiences. I should get a replacement drive back in about 2 weeks max. If there's a problem with that one, I'll update my review but I have always been pleased with WD drives. They have a much less failure rate than Seagates I've had experience with over the decades. So sticking at 5 stars, even though I have a DOA, because their support is outstanding. Try that with Seagate.... Original Update ~~~~~~~~~~~~ I have a number of these drives in a server as well as in a NAS. I use them directly in a server for storage for a Media Center system. In the NAS they're powered up 24x7 whereas in the server they get powered up and down each day. I've not had any problems with them. The only reasons I keep buying them is because I'm upgrading from smaller capacity WD Red drives not because any of them have ever failed. This purchase was to create a USB backup device but I'm actually using it to replace a smaller 6TB drive instead. What made this even a better deal was buying it during the Amazon Prime Day and got a great discount on it. None the less, these NAS drives are solid and I now added them to other servers as Data drives (using SSD's for boot devices). Highly recommend them.

I hate to review components like these until I've had them a long time, but now is probably the time for harddrive buying in general. First of all, to those who are wondering, no the 5640 RPM is not a typo. The official specs sheet says that's what it runs at. I think this helps it find a better balance between 5400 RPM power efficiency and 7200 RPM responsiveness. It claims to run cool and it does seem to do so. One lucky surprise is that it's quiet. A lot of larger harddrives intended for NAS or other RAID systems don't really try to be that quiet. According to the spec sheet it's officially 24dBA idle, 28dBA access. That's insane. I can't measure it with digital precision, but I can say it's one of the least annoying sounding drives I have used in a long time. Even many 5400 RPM 2.5" harddrives bother my ears these days (SSDs have spoiled me!) It doesn't seem to have quite the same "whoosh" sound of the actual platters spinning that normally bothers me if a drive is at all close enough to hear. (How did I survive harddrives in the 90s??? I don't know!) This thing is almost whisper quiet and putting my ear right up to it can still make it hard to hear. I think maybe the 5640 RPM contributes to this — likely it strikes a better balance in regards to sonic properties. My best guess is vibrations don't interfere with each other as much or something to that effect. And even the "grinding" when it's accessing data is quieter than most. I went ahead and wrote this review now in part because I just really want to emphasize how much quieter this drive is compared to most. As another piece of good news, this entire series is made with CMR — that is classic magnetic recording — rather than SMR (shingled magnetic recording.) A lot of larger drives in this sort of range use SMR because it's cheaper, but it also is significantly slower on any writes bigger than the cache size — which is probably going to be any decent sized transfers at all. I also see a lot of claims that SMR drives last significantly less actual usage hours (which might make sense since they must rewrite every single block that changes for even a small write.) Right now I have more confidence in a CMR drive to hold up past the 1.5 year mark that seems to come up a lot in reviews and complaints for SMR drives. Speeds did dip down to something like 160MB/s for the final average (instead of the 215MB/s in the specs) for a huge transfer operation, but all in all this drive strikes a lot of great balances. Only time will tell on reliability, but this is a good line.

Drive is a good value for the money. It is easy to install and is very fast for not being an SSD. I haven't seen any data loss. The drive doesn't seem to run hot.

Ships in a state where most NAS units think it's dead Newer batches of this drive ship from the factory with PUIS (Power-Up In Standby) enabled. The drive won't spin up on its own when it gets power. It just sits there waiting for a command most NAS enclosures never send, so your NAS reports it as a failed drive with blank model and serial info. I got two from the same batch (this one plus one from another retailer) and both did the exact same thing in every bay of my Ubiquiti UNAS Pro. An older drive of the same model works fine in the same bays, so this is something WD changed recently. The normal fix is disabling PUIS with hdparm on Linux, but you can't do it over USB. I tried three different USB docks and the bridge chips in all of them block the command. You need a desktop with a real SATA port, which a lot of NAS owners don't have. I wasted many hours figuring all this out before returning it. The drive itself is probably fine. But selling a NAS drive configured so that actual NAS units call it dead, with no reasonable way for a normal person to fix it, is ridiculous. Buy a different model until WD sorts this out.

This WD Red Plus drive is a good choice if you want something made specifically for NAS use instead of a regular desktop hard drive. The 2TB capacity is enough for a smaller setup, and the CMR recording gives me more confidence for long-term storage and regular read/write use. It runs quietly enough that I do not notice it much in my enclosure.

I really dislike that Amazon decided to ship a disk drive to me in nothing more than the retail box with a shipping label slapped onto it, but so far it appears to have survived. I put it into my Linux system with zero setup issues. Prices are insane right now. Thankfully, I caught it at a time when it was somewhat reasonably priced ~$130, but at the time of this review, it has jumped an additional $70 or so. What can ya really do in times like these, though. 4 stars for the drive itself, 1 star for Amazons shipping methods. Do better, Amazon.

I bought two of these to install in my DAS enclosure. One worked great and the other was DOA. I've bought 3 Blacks, 1 Purple in the past and now these 2 Reds and of the 6 total only 1 was DOA. Amazon's return is the best and having a Whole Foods near by makes it is easy to send things back. I wanted a DAS to save important files and needed two drives to mirror everything. I always go with Western Digital when it comes to mechanical drives and they work great if not DOA. They sit silent in my DAS until I accesses a file on them and I can hear them spin up. I have used this brand for many years and I am confident they will last a long time.
