Hello The SATA speed is determined by the I/O controller. The R630 uses the Intel C610 X99 chipset for I/O control. It supports up to 6Gb/s. The max speed should be the same with the S130 since it still uses the chipset for I/O control. [URL] [URL] Thanks
I know a proper RAID device will be MUCH better However humour me. "Embedded sata" is an option on the dell configuration page, all I wish to know is 1) The speed,.(in AHCI) 2) Is the speed the same when in (cough) "RAID" (fakeraid)    
R430 embedded sata speed?
