SATA is the newer tech. SCSI has been around for a long time.
For a desktop SATA2 is the way to go. The most bang for the money. Also, ignore 10,000 rpm or 15,000 rpm. they only way a person will ever know the difference in harddrive speed is if they use bench marking software. Hard disk controllers and hard drives themselves have on board memory called cache that helps move data at faster rates.
SCSI is specifically for servers or video editing solutions. It moves data at a constant rate were as SATA and the older ATA work at high speeds by using burst technology.

SCSI have a controller on-board, and SATA uses the PC as a controller. SCSI had an advantage for a long time but PC speeds are up and SATA is sometimes faster than SCSI.
I looked around for some data... Take a look. Sorry the pics are a year old but in the year, PC speeds are higher, so SATA is probably better.

;-D I just got a new drive. 200 GB @ 7200 RPM and it is soooo cool! I have no idea what it is! hahaha It is a firewire drive though.

Performance in real world use would be similar. Generally, SCSI disks spin faster,typically 10,000 rpm,and you usually need a controller card for use. SATA disks use a small round interface cable rather than the flat ribbon cable on PATA disks. Data transfer rates are generally faster too. If you have and older computer you will need a controller card to use SATA disks.

SCSI=Small Computer System Interface (or for the old school computer geeks it stands for "System Can't See It"
SATA=Serial Advanced Technology Attachment
The interface for the system bus is handled in different ways comparatively between SCSI and SATA. Differences include maximum speed( both transfer speed and bus interface speeds), and number of concurrently connected devices . for specifics, check the reference websites, lots of info there.
Basically, SATA is slowly replacing SCSI as the default RAID handler with higher RAID transfer rates and performance due to its ability on the high end to push greater bandwidth than older outdated SCSI Technology.
I hope this helps.

SATA hard drive's stopped being made a couple of years ago, and SCSI have a faster RPM, which are the standard in new computers.

SCSI Vs SATA
SCSI has been the standard HDD for network servers and raid configurations.
SATA has a comprable speed of SCSI and work good for desktops.
But if you put them in a raid configuration on your desktop under windows...The overhead seems to bring the speed down.
