I'm looking into an Intel Chasis, specifically Intel Astor. The chasis itself includes a SCSI SCA-backplane which is specs to operate at 40MB/s. But I'm interested in attaching four 10k-rpm drives or even Seagate's 15k-rpm X15 drive into it's five drive capable SCSI SCA cage. So the ability to support 80MB/s is crucial. Of course U160 would definitely be nice too. So does the SCSI SCA-II capable backplane that's only spec to UW operate at say 80MB/s? Since SCSI SCA-backplane is more like electronic with circuits and terminators I assume it'll only operate at what it is spec at, in this case 40MB/s. BTW, it's only able to take single-ended drive. So in this case it woulodn't be able to support LVD mode so it'll defintely be operating at 40MB/s? Any thoughts would be appreciated,
