I'm re-jigging my home storage again so I am selling four Western Digital 4tb 3.5" RE Datacentre drives (all still with plenty of warranty). For those of you unfamiliar with these drives, they were/are Western Digital's top of the range SATA disks for NAS/Server use - they are designed for 24x7 Datacentre usage, so should be bullet-proof for home use! The offer better performance and reliability than WD RED or RED pro drives (they are 7200rpm RAID drives as opposed to the REDs, which are 5400rpm drives). That's why these drives came with a 5yr warranty from new while REDs only include 3yrs from new. I believe the most comparable drive in the WD range are now the Gold drive series. For reference, I ran an array of these as well as an array of RED drives, and the RE's were consistently faster for both reads and writes. When I purchased these, they were approx double the price of comparable REDs, but I managed to find a deal so while they were still significantly more expensive than REDs, I was happy to pay the extra for the additional warranty, performance and reliability. Specs are here - https://www.wdc.com/content/dam/wdc/website/downloadable_assets/eng/spec_data_sheet/2879-800066.pdf I have checked all drives with HDTune and no errors noted (they are still all under warranty so no worries anyway on that regard).
