On: Think of solid-state drives as multi-core storage

"SSD drive is similar to having a striped RAID of four rotation drives"

You are still limited by the speed of a SATA channel, so a striped hardware raid of SSD drives are going to be faster still.

[coffeemug → pmorici]

Nah, a single drive won't saturate SATA (not in the situations I'm testing under, anyway), but a RAID of multiple drives might saturate SAS (not sure yet).

[pmorici → coffeemug]

So, in your experience motherboards like this one, http://www.tigerdirect.com/applications/SearchTools/item-det... that have regular SATA and support "RAID" do you getting 3Gbps total, or 3Gbps on each port?

[coffeemug → pmorici]

I don't know. We're testing one drive at a time for now, so we don't have very much information on bus saturation. I expect to move on to RAID controllers/Motherboard testing in a month or two.

Intel and Indilinx SSDs are saturating SATA today for sequential reads, but that's generally not why people use SSDs.

Ironically, many SAS controllers can handle fewer IOPS than an Intel ICH SATA controller; SAS 2.0 controllers are supposed to be better in this regard.
