Yes, there can be, but there aren't many out yet if any. Furthermore, you can still compare via form factors. http://www.storagesearch.com/ssd-buyers-guide.html mentions Seagate's SAS-connected SSD devices as having: 400GB (SLC) or 800GB (MLC) capacity 360MB/s reads 300MB/s writes 48K/22K sustainable random R/W IOPS respectively That's less than PCIe-connected storage, but much faster than rotating media (probably double the sustained and about 400x faster IOPS). Of course, you can always RAID. When someone asks about IDE devices, we know they usually mean PATA, despite every drive on the market today being IDE. I guessed at what I think the OP was asking and answered it. If that's not what he was asking, he can speak up and clarify. /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
