Serial Attached SCSI or "SAS" as it is commonly known, has been around for a while but it certainly hasn't taken off, especially in the Desktop space, like Serial ATA (SATA). GamePC, one of our favorite places for serious technical analysis and a highly underrated site, takes a look at a pair of Seagate SAS drives and compares them to WD's 10K RPM Raptor drives. Of course the 15K RPM SAS drives rip up the Raptors in RAID 0 testing but then again the older 74G Raptor models were used (for-shame!). Regardless, there's good data here for consideration in your next RAID setup.
We're going to be rounding up a bunch of PCI Express-based SATA controller cards here at HH in the near future and we think you'll find it to be a fairly interesting perspective on alternatives to on-board RAID controllers. Hardware-based RAID versus Software-based RAID and what to do with that shiny new X4 PCIe slot on your motherboard... decisions, decisions.
