I would prefer a hardware SATA raid like the 3ware cards if doing more than 2 drives.
So, why not get SCSI that supports the same thing?
Ah, didn't know about that one actually, havn't researched SATA drives being manufactured in a while.Lastly, all SATA drives have either IDE or SCSI interfaces anyways before they go to the SATA channel.No quite a few new SATA drives are native SATA and are not IDE or SCSI internally.
Thats what SCA is for. Easy to adapt into any SCSI system even if it does not defaultly support SCA with a $5 adapter. I've never had a bad drive ever take down the channel.The scsi cable shared by all scsi drives in a system is fairly fragile, and loosing it looses all drives, and in some cases a drive failure takes out the bus too. With a cable per drive that problem at least goes away.
So you've got my interests in SAS. What kind of system is it exactly? Targeted market? Compatibility? Expected release? I'm thinking a search on google for 'SAS' would give me a lot of what I'm not looking for. lolIt doesn't solve the issue of what happens if the controller dies, but scsi has that issue too unless running multiple controllers on the bus (which is an advantage of scsi very few people take advantage off. Maybe SAS will change that). I used to be a scsi fan, and built machines that used scsi instead of ide, but not anymore. SAS I can see a point in, plain scsi I can't.
