RAID Performance w/ four Patriot Warp 2 SSDs - Up to 660MB/s

@ 2009/01/19

We are back on the subject of Solid State Disk drives again and this time you're in for a real treat! This will be an adventure into extreme high-end storage with massive amounts of performance on tap. We managed to convince our contacts over at Patriot Memory to send us on over a grand total of four of their impressive Warp 2 SSDs.

What we are aiming to achieve in this article, besides showing off incredibly powerful RAID 0 performance, is to give consumers an idea of the level of read and write performance they can expect when running SSDs in various RAID levels. We covered them all - count them... 0, 1, 5, 6, 10 and single drive for good measure. We even tested with write caching enabled in RAID 0."

Are you sure of that? The problem was at the firmware/controller level regardless of cache on the SSD. I just am not sure that a RAID controller could fully or mostly mitigate it.

Was some interesting tidbits on the issue in the W7 performance metric article. http://blogs.msdn.com/e7/archive/200...nce-index.aspx

Agreed, but I wouldn't worry too much about the ssd controller, as it's (lack of) performance is completely "flattened" by the onboard cache from the RAID controller.
