Western Digital Velociraptor 1TB 10K RPM SATA III 2.5-Inch Internal Hard Drive (WD1000CHTZ)

I am an electrical H/W engineer with 35 years of design experience. Have designed numerous products including networking equipment that uses Sandy Bridge, Ivy Bridge, Haswell and Broadwell Intel embedded processors. This equipment is used at Amazon, Apple, Google and numerous other high end companies. This equipment also uses dual 1TB WD1000CHTZ VelociRaptor hard drives. These drives are "enterprise" class hard drives, meaning that they are high performance and high reliability drives.I don't use the "ice pack" really a waste of space and money. Instead mine are mounted on drive sleds/trays that slide into a quad tray 5 1/4" drive slot. This 5 1/4" quad drive bay has two VERY quiet fans that draw air in from the front, thus very efficiently keeping the drives cool. Drive bay part number is BP-SAC1425AVL 2.5". I clone my hard drives (operating system drive, data drive #1, data drive #2 and data drive #3. That way, when the inevitable virus infection occurs, my MASTER offline operating system drive is cloned back onto my working online drive and the virus is gone. Virus usually infects operating system drive.Having said all this, I have ten of these drives and have had ZERO problems. I use Windows 7 with MBR (not UEFI) boot records on the hard drives, which limits drive size to 2TB, but that is OK. If you have a large hard drive and it fails, you lose lots of data. 1TB seems to be the perfect size.The performance and reliability of this drive is excellent. Yes, they were manufactured in 2013, but new "old stock" that is unused is just as good as the day it was manufactured. That is why this drive is reasonably priced. These drives used to sell for $450, so $135 is a steal.

I bought this hard drive to replace an old HD that was starting to fail. I use this as a secondary HD mainly for video's, music, photo's, etc... and I use a Samsung Pro SSD for my main HD to run all of my programs and games. Overall I am very happy with the drive. It is small, cool, quiet, and fast for a mechanical drive. I never hear this thing spin up so it has been very quiet.However I do have one issue and that is with the stock photo they show above... this drive does not include the 3.5" heat sink like what is shown in the photo and I had to buy that separately for an additional $25.00. Kind of deceiving when they show it in the photo and it doesn't state clearly in the product description. Otherwise still the best mechanical drive you can buy.

haven't had it long enough to know if i "love" it (5 stars) but gotta say that the price is right compared to similarly sized SSDs. and on my system, this mechanical drive is as fast as an SSD (Samsung 850 Pro) so win win!

I bought a used one and it had 20,000 hours on it.

This drive is really fast. If your looking for a great gaming drive look no further than this. the price is so good you can't believer your eyes. If you are going to use this as an internal drive in a 3.5 inch bay you will need to purchase a 2.5 to 3.5 inch adapter.

rock solid reputation and personal experience with these drives. this purchase met my high expectations

The hard drive is advertised as being 2.5 inch internal, and comes with mounts for a 3.5 inch drive mounting. Unfortunately the only way this vould be mounted is in a 3.5 inch bay due to the thickness of the drive. When I say it is twice the thickness of a standard 2.5 inch laptop drive I am not joking because it is closer to 2 1/2 the thickness.That being said, the drive is amazing, and we'll worth the price I paid even when I have to add on an 3.5inch enclosure.

I have purchased two of these. One has been my main hard drive for a year now, the other was more recent and came defective. The seller quickly replaced it even before the return had reached them. The replacement has been great. These are quick hard drives, only outclassed by WD Black 6 terabyte drives do to their updated design and data density. That's right, this old 1 terabyte is quick. All of mine have been 2.5 inch drives without the heat sink. Another seller sells the heat sinks separately for a decent price. For about $100 (the price at the time of writing), this is a good deal in my book. Now, if only WD would release another version!
