I still think SATA is no big deal. This link supports my view. - Tubtanic
"Helbig admits that at 150MB/sec, SATA offers no performance advantage
over IDE, especially as the parallel-to-serial bridging technology in use today can limit real throughput to less than 100MB/sec.
He adds that even when SATA-2 comes along with 300MB/sec and extra
features such as command queuing and drive hot-swapping, SCSI will still
have the high end thanks to its advantages in areas such as error reporting and defect block handling. "
"Kevill says that a 3Ware SATA RAID adapter costs around 20% more than the equivalent IDE RAID card, because of the extra bridging chips needed, and that it adds £15 to £20 to the drive price.
"However, there are still a couple of SATA caveats. Firstly, the connectors are weak and they really need the addition of a locking clip, warns Romain
Cohen-Gonsaud, an area sales manager with disk enclosure supplier CiDesign."
And at the launch of EMC's first IDE-based Clariion storage boxes, senior
vice-president and general manager Joel Schwartz robustly declared that
SATA hard disks are not yet ready for EMC's customers.
"There are no SATA drives on the market today that we feel comfortable
bringing to market," he said. There are reliability questions, he said, and some drives do not support hot-swapping. "We will move to SATA as soon as it meets our commercial standards," he added.
