I have the 750gb in my laptop and it screams. Neat concept of speed benefits (to a degree) of being part SSD, plus size of storage of a regular hard disk, for a decent price. I'm tempted to use one of these as a cache drive .... but would make a nice laptop upgrade too.
June 8, 201214 yr I love these drives, I have two! I don't think they are a terribly good choice for an unRAID cache drive, however. You want a cache drive to have fast writes, but you don't really care about the reads. This drive is the opposite: normal writes (as they go to the platter), but fast reads (as they are buffered in the SSD portion of the drive). So this drive won't perform any better than a standard laptop hard drive when used as an unRAID cache drive. If you run lots of apps from your unRAID cache drive then this drive might be a good fit.
June 8, 201214 yr Hrm, I just looked up the performance of this particular drive on PassMark http://www.harddrivebenchmark.net and its score is 560. The 7200 RPM 750GB WD Scorpio Black 2.5" hard drive got a score of 764--but it's like $100 The only reason I mentioned this is because I was looking at performance of 2.5" hard disks last night because I want one for my desktop. (I have this little 4 bay 2.5" raid cage--fits in 5 1/4" drive bay).This little 750GB I mentioned is faster than my WD Black 3.5" 7200RPM 1TB drive which got a score of around 650.

The WD Scorpio Blacks perform great. I use a 320GB model as my cache drive.

Yes, the 2.5 inch laptop drives. http://www.wd.com/en/products/products.aspx?id=130
