Summary: I had bought 2 of them in Dec 2012. Used them as RAID0 under Win 2008 R2 Server. I ran multiple Virtual Machines. It ran fine until I got corrupted data and SeaTool confirmed drive-errors. Mid September 2013, returning to Seagate. They ran fast but died faster.
Summary: This is not a mac friendly drive. I spent 2 weeks looking over apple reviews and tutorials to try to find information on making this drive work for me. No luck. It appears that there are inconsistencies in apples hardware that make some computers ok with this drive and others reject it.
Summary: So I read that this drive does not sleep in MacBook Pros. I chose to ignore these posts assuming it was user error. Well, after getting the drive delivered and installing Lion, I can confirm it does not sleep. You close the lid on the computer, wait, and hold up to your ear.
Worked fine for 5 months then it died a slow death

Summary: I bought this about 5 months ago. Installation was easy enough and I have several friends who have these drives in their macbook pro computers with no problems. I, however, was not so lucky. After about 5 months (even with firmware updates) I started experiencing momentary hanging.
Summary: I purchased a 500GB Momentus XT Hybrid for $99.99 back in December of 2010. Whe the device arrived, I installed it and loaded Windows XP Pro, with over 17 years in the computer I.T. field, I was confident this wouldn't be a problem. The drive worked very well UNTIL early March 2011.

Summary: From researching hard drives, due to my macbook pro's hitachi hard drive failing, i came across this SSD hybrid drive, which from what i read had positive reviews, especially from macbook users.
Summary: I bought this drive in April 2013 to replace the failing original (Hitachi) drive in my HP laptop. It was considerably faster than the original, as well as larger. However, it has failed quite spectacularly over a three-day period with bad sectors and messed-up file indexes all over the place...

Excerpt: Speed improve as advertised, ***if*** you don't use that quite a few apps all the time often. If like me, you use a lot of apps all the time, all with equal regularity, then the 4gb is really not adequate to hold them all (causing the cache to keep finding refreshed), and you are back to a normal...
