Review: Well-performing drive and not too noisy, but make sure to avoid OEM/grey-market units - I bought two units of the 20TB version of this WD Red Pro drive for my new storage system. I particularly went with the 20TB version, because - according to the datasheet on Western Digital's website - it is less noisy than some of the lower capacity models. I tested one of the units, not in my storage system, but in my open bench USB 3.0 to SATA Adapter (with a max transfer rate of over 500MBps). It performed well, the sequential read and write speeds as high as ca. 270 MBps and ca. 130 MBps on the low-side. This is typical of all HDDs: on the outside of the drive they can pack more data on one track than on the inside, so on each rotation they can write and read more data on the outside area of each disk platter. The write and read tests were also successful, no bad blocks were reported. For some performance figures, please see the attached screenshots (which have the serial number removed/redacted). Please note that the CrystalDiskMark results are performed on an empty HDD, so they seem to be executed in the "fast" section of the drive. The other graphs were taken from HDSentinel, relevant there are the bottom graphs, which show transfer rates across the surface of the drive. The sound of my test unit was also pleasant enough, the clicking wasn't too bothersome. But since I will move this drive into the case of my storage system very soon, the clicking will be a lot less noticeable than it is already. One action I always perform, BEFORE opening the product box of an HDD or SDD is to check the serial number on the box against the manufacturer's warranty website to ensure that the item is covered by the manufacturer's warranty. I do this both when desertcart is the seller and when a 3rd party is the seller and desertcart is just the fulfillment party. (I do not buy HDDs from a 3rd party seller that does not have fulfillment with desertcart.) This is to avoid OEM/gray-market units that aren't covered by the manufacturer's warranty. A store warranty by a 3rd party seller is of no use to me, since these sellers come and go and I also don't want the hassle of dealing with them. Since the Red Pro series offers a manufacturer's warranty of 5 years, and HDDs fail frequently enough to make such a warranty very valuable, I always insist getting the manufacturer's warranty and even will query 3rd party sellers, if their stock with desertcart is covered by such a warranty. As it turned out, the serial number of second 20TB HDD that I ordered (from a 3rd party seller, since desertcart themselves were out of stock) did not show up in the manufacturer's database for U.S. warranty, so I can only assume that it is a gray-market unit and I immediately returned it. (I can only hope that the 3rd party seller will have to bear the full cost of this return, since I emailed them and asked about the manufacturer's warranty, before the item ever shipped, but they didn't answer my question.) One more tip: There has been some research that failure rates of HDDs from the same batch are somewhat correlated, so I always try to space out my purchases (either in time or by using different vendors) to increase the chance that I will be getting units from different batches. That's why I bought from two different 3rd party sellers on desertcart (one of which apparently sold a grey-market unit), without disclosing that fact ahead of time.

## Questions & Answers

**Q: 4 of these drives good for 32tb 24/7 dlna nas server? Don’t want to beat a dead horse here... Really it’s just to stream my 10Bit 4K movies using DLNA**
A: It all depends on what size and what RAID configuration you are asking about.  Most people would be using RAID 5 or something like Synology's SHR (similar to RAID 5 but doesn't require equal size hard drives) for this purpose. If you are thinking that 4x8TB will give you 32TB of storage that is not correct in RAID 5 because of the overhead used for data protection.  It works like this for RAID 5, 4x8TB = 24TB storage, 4x10TB = 30TB storage, 4x12 = 36TB storage.  So first determine which RAID configuration works best for you and then find a RAID calculator available online to choose your RAID configuration and hard drive size.  If you just want speed, with no parity checking then you could go with 4x8TB or 2x16 TB (whichever is cheaper) in RAID 0 for 32TB of storage but file corruption could be an issue and there is a possibility that you can only do 2 hard drives in RAID depending on your hardware.
Having said all that, these drives will certainly stream 4k 10-bit HDR movies over DLNA.  Streaming 4k is just as much up to the software and hardware of your computer than it is the hard drives.  A nicely configured Windows machine, for example, may stream them fine however a less powerful NAS device may not.  There are a lot of moving parts but these drives will not be an issue.  There are also issues with playing the 265 codecs in Windows 10 Media Player but the same files that will not play in Media Player, will stream via DLNA to my LG TV just fine and play in full 2160p HDR with no problem.  These same files will show up fine in my 9 year old NAS but will not stream via DLNA on it but photos stream fine.  So it all depends on your exact configuration.  But the drives are fine.
If it all gets too hard then just get a fast (say 400 MB per second) USB stick and copy 10 movies at a time on to it and plug it into your TV.  The Samsung BAR Plus 256 GB works well for this in my experience.  You can also look into getting streaming server software on your computer and a client connected to your TV.

**Q: What is the difference between this and the WD Black drive?**
A: The Red is engineered for 24/7 usage.  The Black is not.

**Q: Is the red wd drives better for cctv/nvr in raid setup than the purple drives? i hear purple drives are not lasting long. both red and purple are 24/7**
A: I use my purple drives with 9 cameras 24 x 7 and have over three years without a single failure.  pretty good if you ask me.

**Q: Can I use this as an external storage for my desktop?**
A: I have four of the earlier 3tB versions of this drive in external USB3 enclosures and use them in rotation for critical full system backups. They have served very well in that capacity. I also have one of the 3tB drives in my main daily-driver computer now and it does that quite well although it isn't as fast as some but since it is used mostly for secondary data store it doesn't matter so much. The reason that I have so many of the older 3tB drives is that I upgraded all of the drives in my Drobo NAS to 6tB drives a while back. Those drives as well as five of the 8tB units in another NAS have worked perfectly so I can highly recommend them (for the proper use, of course).

### ⭐⭐⭐⭐⭐ WD Red Pro NAS drives are solid drives
*by M***4 on May 18, 2023*

Using 2, 4TB drives in a home RAID array for photos, videos, etc. Main drive is an SSD but decided to go with these for bulk storage as they are a bit cheaper (guessing my last time buying HDD's and next time will just use SSD's because they are just so much faster). Drives seems to perform nicely and other than a little HDD noise here and there don't find them bothersome at all. Previously had 2, 2TB of these red drives in a RAID array (had it running for about 8 years) and never had any issues. In our office we have Gold versions of these running on a backup server for about 6 years with no issues. All in all, very reliable. Speed is fine, but obviously not going to compare to SSD. One thing about size of the drives which I see some comments on... The size of the 4TB drive is going to be approximately 4 trillion bytes (mine is 4,000,765,177,856 bytes), however your system will likely report that as 3.64 TB or 3.726 GB. The reason for this is that Windows computes 1GB as equal to 1,073,741,824 bytes and 1TB as equal to 1,099,511,627,776 bytes. These numbers are achieved by raising 2 to an increasingly greater power till you get your first number in the billions and then trillions. There is some technical reason why this is done, but ultimately it is just confusing as it creates 2 different ways of computing size. One, counting the actual number of bytes and the other, dividing your bytes by one of those numbers to get the amount of GB's or TB's. For MB the number Windows uses is 1,048,576 bytes (for example a 20,000,0000 byte file will be reported as 20,000,000 / 1,048,576 = 19.07MB). In any case, here is a summary of the approx drives sizes and around what Windows will report the size as (assuming the drives sizes represent actual bytes exactly, so 4TB for this calculation will be 4,000,000,000 bytes and not the number my computer showed above... so expect the actual numbers to be slightly higher than these): 2TB Drive = 1.82TB or 1,862.65GB 4TB Drive = 3.64TB or 3,725.29GB 6TB Drive = 5.46TB or 5,587.94GB 8TB Drive = 7.28TB or 7,450.58GB 10TB Drive = 9.09TB or 9,313.23GB 20TB Drive = 18.19TB or 18,626.45GB Hope this clears up some confusion here.
