We just put a new dual-Opteron server into our production environment.
We ordered a Megaraid SCSI card and five 10k drives, and a 3Ware
Escalade SATA card with six 7200 RPM drives (Maxtor) to see which ones
were best.
Our network guy did a bunch of benchmarking on the drives and found that
SCS
The single biggest difference between SATA (or any IDE) and SCSI is
command queuing. Command queuing allows the drive to intelligently
reorder reads and writes to make things faster.
An ATA drive executes a bunch of commands in the order it gets them,
which can be slow if it needs to write data

'Almost' is a key word. Some SCSI disk are working at 15k RPM, which will give
you a HUGE MySQL performance growth compare

Hi,
We are currently using a 4.0.16-replication-setup (debian-linux, kernel
2.4.21, xfs) of two 2.4ghz Intel-Pentium4 systems with 3gig RAM each
and SCSI-Hardware-Raid, connected via gigabit-ethernet. We are reaching
the limit of those systems and are going to buy new hardware as well as
upgra
