Don't know; there are 19 reviews on Newegg (several from Mac owners) and they're all good. I've been watching this one for awhile, waiting for a good sale, and this is it! I ordered mine today.
If it's anything like their Desktop drives it'll be a solid performer. I'm a big fan of Samsung drives, owning 3 1TB F1's in my Mac Pro. Always run about 10-15 degrees F cooler than WD or Seagate, and very very quiet.
I am curious as well. I have the 2010 13" MBP with the 250 GB HD, and was wondering if this would make that much of a difference...other than size of the drive obviously. I wouldn't want it to kill battery life, so you guys post your experiences!!
