    • As good as a new drive
Works very well so far. Normal noise levels, fast read and write speeds, and good thermals. It came with appropriately sized piece of kapton tape, an adapter, and instructions on how to cover the pins if it is needed for your use case. The S.M.A.R.T. shows 0 hours powered on and the first power cycle on the first boot. ... show more

    • They look and work like new...
They arrive very well packaged, with a sealed antistatic bag, without the slightest scratch. It claims to have 0 hours of work!! I ordered 3 18TB and one 16TB, they all work very well and even much quieter than an Ironwolf, plus double the cache. I would not hesitate to buy these hard drives again.

    • Silent. Fast. Large. Likely very reliable.
I got this disk as Renewed, but, according to intact packaging and SMART attributes (never turned on and zero time on), the disk was absolutely new. Please beware that the disk uses new SATA interface that says the presence of 3.3V signal on 3rd pin now means "put the drive into sleep mode". Revelation: most power supplies do send 3.3V there. Result: it looks like a dead disk. I shall say I blame mor... I mean, smart people from SATA committee -- not WD engineers -- who, in their infinite wisdom, required backward-incompatible change. Solution: either get rid of pin #3 (e.g. by taping or painting it over) or use 4-wire -- 2 x ground (black) wires, 12V (yellow), and 5V (red) wire -- instead of 5-wire (same as above + brown or gray 3.3V wire). The thing is that hard disks do not need 3.3V power, believe or not, and never needed. Fortunately, the package included 4-wire SATA power adapter. Thanks WD! The disk is outstanding. Almost no vibration and so quiet -- even during operation -- that it is hard to tell that the disk is on. And it really fast (for a mechanical hard disk -- SSDs are much faster, but are much smaller and much more expensive per byte of storage), easily reaching 215-220 MB/s even when 60% full (270-280 MB/s when empty). Impressive. Super-large 512 MB cache is used efficiently too. And it is doing it all silently! Very impressive. 18 TB size, combined with relatively expensive and fast conventional magnetic recoding (aka CMR) vs much cheaper and slower SMR, and reasonable price make it one of the best disks on the market today. I can only hope the HC series will be as reliable (the disk carries, AFAIK, 5 years of warranty, not the usual 3 years) as other Western Digital and HGST disks. If so, it is a steal. At least for me. ... show more

    • Zero hours
I realize that buying refurbished is often a crap shoot regarding previous usage, but this one arrived brand new according to all of the SMART data testing I did. Very satisfied, especially for the price. It's also worth mentioning that dreaded fact that usable storage is always lower than what is advertised. In this case, an 18TB drive is actually about 16TB of storage space. ... show more
