It sounds like he's asking for comparisons between SSD devices and SAS hdds--a reasonable question to ask.
Rotating media will exhibit variable performance based on access patterns and data size, while SSDs will usually offer much more consistent performance and their published specs are more useful. I can already tell you that SSDs will generally outperform even 15k rpm SAS drives. However, there is still form-factor, cost ($/GB), and power to consider. I have an OCZ Revodrive X2 (4x PCIe card) in my desktop which produces >700MB/s streaming reads and writes. The specs claim it can handle over 100k IOPS. Try that with an hdd. The card I bought is currently selling at just over $2/GB. The next closest thing out there is from iofusion--but their products are $10/GB or more. If you're worried about longevity/write wearing, don't. If you need convincing why it's not an issue, see this article: http://www.storagesearch.com/ssdmyths-endurance.html /* PLUG: http://plug.org, #utah on irc.freenode.net Unsubscribe: http://plug.org/mailman/options/plug Don't fear the penguin. */
