Hmmm... Really happy with the speed of the new drive. 30 sec boot time is awesome. CS5 runs like never before. I'm running it in late-2008 uMBP 2.53GHZ 4GB ram 512MB 9600m GT. My frequent Xbench results are in the high 230's to low 240's. The first results after installing the drive were 220. But my results seem a lot lower than others with the X25-m 80gb g2..... should I be worried? Specifically the 4k reads seam rather low usually bouncing between 9-13 mb/s. I figure now I'll just use it, I like the new experience. If it goes bad i send it back. IS that the right thing to do? My best results yet after using the system for a few hours.
