Dell PowerEdge SC420 SATA speed
I can't find any info, but I was wondering if the PowerEdge SC420 internal SATA connections is Serial ATA/150 or SATA 3 GB/s?
Thanks

Yes, thank you. I'm already running 1Tb drive Western Digital drive, which has a transfer speed of 3Gb/s . I know you can buy eSATA cards that support either Serial ATA/150 or SATA 3 GB/s. So I was wondering if the internal SATA connections are limited as well.

Yes, thank you again. That I already know. I'm using 1Tb 3Gb/s drives on a Sata 150 PCI card along with another 1Tb drive connected to the internal SATA connection on the Dell. But I was wondering if the Dell's internal SATA connections are Sata 150 or 3Gb/s. I want to make sure I'm getting the correct throughput.

Sata 2 is backward compatible with sata 1 and sata 1 disks will work with sata 2. Most sata 2 disks have a jumper that forces it to sata 1 if it has problems.
