Good quality
Pricey but good quality.

Work Great, Good Value
Bought these for my NAS running Plex. Arrived quick, well packaged. Been monitoring them for a year in constant use and not a single issue. Not really much more you can say.

Reliable WD RED PRO Nas Hdd
As described, arrived early and was securely packed. Not used as yet as I am waiting for a Nas enclosure to expand my network storage. This Hdd comes with a 5yr warranty and the project was the best at the time of purchase.

Poorly-packaged, missing sectors after a couple of weeks use, deteriorated since.
Package arrived in a small plain cardboard box. No fragile label and no outer box with foam packing. Clearly split from a much better-packaged and protected job lot case and cheaped out on transit protection. It was an urgent order, so I didn't have the time to refuse delivery for inadequate packaging or fully test and RMA it. My preferred supplier Scan UK only stocked up to 18TB Red Pros at the time these 20TB drives were the highest capacity and now that 24TB Red Pro drives have been out for months only stock up to 22TB. I wish I had refused delivery or returned. Within a week there were a few bad sectors. Health in HD Sentinel has now in 2024 (T+2yrs) deteriorated to CRITICAL 10% Health with 854 BAD SECTORS during self test.40 WEAK SECTORS S.M.A.R.T. 5,Reallocated Sectors Count,1,100,100,OK,000000000001,0,Enabled 196,Reallocation Event Count,0,100,100,OK (Always passing),000000000001,0,Enabled 197,Current Pending Sector Count,0,100,100,OK (Always passing),000000000028,0,Enabled 198,Off-Line Uncorrectable Sector Count,0,100,100,OK (Always passing),000000000356,0,Enabled A 10TB WD Red Pro installed in the same machine June 2019 is still perfect with no bad or weak sectors. I expect better packaging, particularly when Amazon overpackage robust items.

WD Red Pro 8TB NAS storage
So, I recently intall the 8tb spinning disk into my home storage server. It's a pretty hefty drive, specifically designed for this kind of continuous operation. I've been testing it out for a while now, and so far, it's been a champ. No weird noises or slowdowns to report. I'm pretty pleased with how it's handling all the data.

Good film storage
I use in my PC as I wanted a more reliable drive for film storage which does not need to be super fast

Old school but cost per TB with this sort of reliability wins over SSD
If NVMe speed is not the driving factor rather a reliable backup is then these are a good alternative I run 2 of these in a RAID 0 set giving me 32TB of backup space and they are very good, Performance is surprisingly fast and as its just two disks after 4 years I'll mothball these as a backup of that day and pop in two new ones (in 4 years time that's more likely to be SSD). Today though with an inexpensive Enclosure its an inexpensive and reliable backup solution when you need high volume backups. I use these as a fast tertiary backup so Raid 0 is fine. I would never recommend Raid 0 as your only backup option.

Noisy drives
Fortunately these arrived in a working state, unlike some others. But after months and months of trying to get these to stop making noise every 3-4 secs in a Asustor NAS, it turns out its own self protection is keeping the drive active even when the drive has zero data on it. FYI yes Asustor NAS have issues with SSD caching and Roon App issues which accesses all drives, I have never used or activated either. Wasted +£600 on noisy drives.

Excelente duración, poco ruido .

Keeps making scrubbing sounds at all time. Won't be suitable for use in a home NAS device, if noise is a concern.

J'avais commandé deux pièces et je les ai reçues très rapidement. Elles étaient bien emballées chacune dans une boîte d'origine de vente au détail. Je recommande ce produit pour installer dans un système RAID (NAS ou ordinateur avec un contrôleur RAID).
