Some users are also jumping on the SAS bandwagon, although few have actually gotten their hands on SAS products. SAS brings some FC-class capabilities and other advances to SCSI, including: Faster disk rotation speeds -- 10K RPM and 15K RPM Dual ports -- the ability to connect the drive to two communications links Serial cabling -- more flexible; easier to work with cabling to the disk Duplex operational mode -- bidirectional access to the disk Greater throughput -- 3 Gbps (6 Gbps duplex) and slated to double quickly 2.5-inch form-factor option -- allows more drives to be packed into a storage cabinet Low price, transparent transition -- prices expected to be comparable with enterprise SCSI drives   "We want the 10K RPM and ... Access >>>
