will serial ata make scsi obsolete?

[PlatinumGold]

as title states.

w/ ata133 and the latest version of scsi there doesn't appear to be a huge scsi advantage.

Actually, SCSI is moving to U320...

SCSI drives normally rotate at higher speeds (15k right now, most drives still being at 10k), SCSI supports drive to drive transfers without bothering the CPU.

For a desktop, there is rarely a reason for SCSI. For a server, there are many pro SCSI

ACTUALLY, scsi is now moving to 640 on PCI-X v2. Ultra320 has been out for quite some time, but only in server markets.


What is really interesting is the fact that SCSI is moving to Serial. :Q THis must be weird to hear, but the amount that corporations spend on scsi-based software enviroments would be too great a loss.


Instead of abandoing SCSI, the interface will just run over serial hardware. Even Serverworks, the king of server chipsets, is rolling out pci-x v2 on their mobos. Appearntly the future looks bright for scsi. The protocols are what really make it shine. I can't wait to try a ultra 640 or Ultra1280 SCSI setup @ 30k rpm WOOHOO!!

DOn't believe me....click here?

In addition, people like yourself have to realize the prime advantages of SCSI.

The interface is ideal for rapid and simul;taneous transfers. Take my Quantum Atlas 10kII Ultra160 HD.

For sustained rates, it gets about 38MB/s, not stellar, but by no means great. It "appearntly" gets its a*s whooped by ide RAID systems in Sandra's benchmarks.


Then check out the access times. Flat out 5-6ms. I guarentee you any, and I mean ANY IDE drive will have slower Acesstimes. It is only 18GB, but since it is quick at acessing a lot of different data streams, it is ideal as the OS/Program files drive.



SCSI isn't going anywhere.....it's just THAT good.


..the fact that the Seagate 36LP's tranfer at a sustained rate of 70MB/s and have 3.6-3.9ms access times doesn't hurt either.
