  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?

Thanks,

jerry
