Excerpt: Drives were bought to replace the stock Hitachi drives in a Mac Mini server, after the OS drive failed. I would have rather replaced them with 2 SSD or Hybrid drives. No problems with the drives to date, and my Mini Server is back up and running.
Summary: I used this to replace the drive in our pre 2008 MacBook Pro. The drive has a loud Buzz or Humm to it and im not really impressed. I have had WD drives in the past, so i hope this is an isolated occurrence. I will be contacting the manufacture soon. other than the noise, the drive test and functions as well.
Summary: I use the drive for my laptop as a USB-3 clone drive. Simply use EaseUSTodo to clone the drive as often as you want. If my Samsung SSD dies, I have an instant backup when I pop the drive in and fire up the laptop again. This has happened only once, but that is enough to justify the price. Very convenient.
