I grabbed a new SSD M4-CT064M4SSD2 from Crucial.
I am disappointed. I stuck the unit in an Atom machine (zotac) with CentOS 6 on the disk. It really doesn't "feel" faster than the previous 5400 RPM drive that was in it.
The SSD is giving me (in the zotac running centos 6): hdparm -t /dev/sda /dev/sda: Timing buffered disk reads: 298 MB in 3.00 seconds = 99.30 MB/sec
The Samsung 5400 RPM disk (in the zotac running Centos 6): hdparm -t /dev/sda /dev/sda: Timing buffered disk reads: 196 MB in 3.01 seconds = 65.02 MB/sec
I'm not supper impressed at all. Sure the numbers say its "slightly" better but I don't "feel" it. I was expecting like really noticeable change in application load time or something - but not really.
Just wondering... Is there something that has to be done to take advantage of the SSD performance?
You need to verify that "AHCI" is enabled for the sata interface.
