WD Ultrastar HC560 WUH722020BLE6L4 20TB 7200RPM 3.5" SE SATA HDD 0F38785

A great 20-TB drive (be sure you know the difference between SAS and SATA) A great drive, and a good cost per terabyte. For most home users, this is the drive to get (avoid the SAS drive with a very similar description, unless you have proper SAS hardware to plug it into -- most people do not). IMPORTANT CAUTION: There are two different 20-TB drives sold on Amazon, both labeled "WD Ultrastar DC HC560." One is a SATA drive, one is a SAS drive. For consumers, the SATA drive is good. The SAS drive is designed for data center cabinets, and while offering a faster data rate, the plugs/pin-outs are not compatible (even though the SATA capability is nominally backward compatible). Don't confuse the two (the descriptions don't do a good job of differentiating the two). Platinum Micro really should update the product description to provide more clarity / avoid confusion between the two products.

I bought this from other sellers, but this seller was the most legit. Platinum Micro Inc. I bought another one before this one and I got a smartctl Failed. this one passed of course. These ultrastar high capacity drives are a little different. They are a little bit more noisy. But they are great for their storage level and price. I am using it will a linux os and for personal/work, not RAID or data center. I formatted it to ext4. Will update if I run into any problems. This is my account on first getting the drive. I generally feel better with WD imho.

Hopefully arriving tomorrow. These are based off the old HGST drive line. Which was hitachi before western digital and Ibm before hitachi. IBM had the "Deathstar" line of drives and did a 180 and became the most reliable drives there are. Im glad these are not hyped as it saved me some coin over the golds. I currently have golds 6tb andc bumping 3 of them to 20tb ea. I will update in the near future.... Edit: 3 came in registered them with WD and I got 5 yrs. Legit. Comes in typical hard drive brown cardboard box. The packing material was some air pods, but there were a lot of space for the boxes to move and bump. But if they last 5yrs then they should be good..... Happy so far. Unraid is rebuilding parity now.

Ive bought three of these and all have been running fine 24/7 (all from amazon, but different seller) needed another one and just bought it 'sold by' Platinum Micro, Inc. the drive arrived not in the manufacturers box and when running the serial number with WD it comes back as a grey market so no valid US warranty. returning. in a pinch it would be fine but if you expect full value from a full priced item this isnt it.

This is used in my personal server, and I can confirm that it is both the quitest and fastest hard drive I have owned, though this is my first helium drive. I love it and will be buying more when I need them.

I've been using WD drives for my HDD needs for years and have always had good luck. I've also been using Ultrastar drives ever since Hitachi introduced them years ago, and the ones I have still work! So, naturally, when WD took over manufacturing them, I figured it was a safe bet. I have 2 18TB models and 2 10TB models that are still going strong, and now, just added this 20TB. Some have complained about theirs being a bit noisy, but I don't seem to have that problem with any of mine. Perhaps it has something to do with the setup of my case and where my HDD's live. One other thing that I really like about these HGST drives is that they run cooler than my WD drives, only a few degrees Celsius, but it's consistent with all of these Ultrastar drives. Compared to other drives of similar high capacity, these are definitely good quality and a good value.

I purchased 8 of these hard drives for a raidz2 truenas configuration. After a few months a scrub detected a URE in one of the drives. The particular drive was fulfilled by SabrePC and was not covered by the WD manuf warranty, however they cover the drives with a 5 year warranty and the RMA process was completed promptly and without hassle. Very happy with my purchase.

WD Ultrastar DataCenter series disks are as good as WD Gold series and are 20% Cheaper. I used them as Raid-10 and/or Raid-1 (Mirror) in Mediasonic ProRaid cases. I have not have any issue so far..(5 years for WD 10TB, 12TB, 14TB, 16TB,18TB)

Se lo coloque a mi pc de escritorio y funciona de maravilla excelente producto
