Review: Ridiculous price but a good drive - Just performed an extended Smart (S.M.A.R.T) test on this 20TB drive via DSM on my Synology DS220J NAS. Test reports the drive is healthy and total power on time was 0, as you'd expect for a brand new drive. So all is working well. I purchased this drive from desertcart and they delivered it too. Packaging was sufficient but really, for an item of such high value, I wish they would do better. It essentially came in a cardboard box with some brown paper used to pad it out - only on one side of the box though - should be on both, and at the sides! Fortunately though, the WD box itself is fairly well packaged with some plastic inserts to hold the drive in place and prevent it making contact with the edges of the box itself. The box was also sealed with a clear plastic label which looked original to me. The drive itself was within an antistatic bag. So the drive is packaged in the WD box quite well - desertcart, not so much. But it arrived in good condition and it's working - that's all that matters. As for the price - the only word I can use to describe it is 'ridiculous'. Not only in the sense that AI data centers are pushing HDD prices up across the board, but the price on desertcart seems to change every five minutes. I won't say any more than that as this review will probably get blocked but desertcart has a 'price history' feature, which I'd encourage you to use. I've never had a WD NAS grade drive before so can't comment on longevity, but my expectations are that this should last at least 5 years and if that proves not to be true, you can guarantee I will come back and update this review! Review: No techy stuff in this review - I know nothing about computers so someone else built mine, but it works and works well so I guess this item is doing what its supposed to. ## Features - Available in capacities ranging from 2 to 22TB(1) | (1) 1GB = 1 billion bytes and 1TB = 1 trillion bytes.

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). ## Customer Reviews ### ⭐⭐⭐⭐⭐ Ridiculous price but a good drive *by A***B on 5 June 2026* Just performed an extended Smart (S.M.A.R.T) test on this 20TB drive via DSM on my Synology DS220J NAS.

Label serial: AE57U3KD Actual drive serial: 2YGJ11DD Western Digital's warranty checker does not recognise the serial printed on the label. It DOES recognise the drive's actual electronic serial and identifies it as an out-of-warranty 10TB OEM drive described as "APPLE iCloud". The drive therefore isn't what its WD Red Pro label claims it is. Returned for refund. ## Frequently Bought Together - Western Digital 18TB WD Red Pro NAS Internal Hard Drive HDD - 7200 RPM, SATA 6 Gb/s, CMR, 512 MB Cache, 3.5" - WD181KFGX - SAMSUNG 990 PRO SSD NVMe M.2 PCIe Gen4, M.2 2280 Internal Solid State Hard Drive, Seq.
