256Gb SSDs and WordPerfect for Windows

Samsung has announced a new 256Gb solid state drive. Production will begin later this year. The initial market is for notebooks, but the real market is for databases. 

SSD drives are faster than hard disks, more reliable, and have different access method performance patterns. Hard drives perform best while sequentially accesses large blocks of data. SSDs are equally capable of accessing random data or sequential data.

This change is as significant as the change from paper tape to mag tape, or mag tape to hard drives. Database vendors that grok this evolutionary step and rewrite their storage engine to optimize for SSD drives will survive. Those that don't will go the way of WordPerfect for Windows (WordPerfect once owned 99% of the word processing market. WordPerfect didn't move to Windows very gracefully, and as a result, many PC users don't even remember WordPerfect.)

i've kept up with SSD news a little, but wasn't there a limitation on the number of writes? it wasn't an issue with things like digital cameras but using it like a HD is different. and what about seek time? i thought it was a lot longer than regular hard disks.

There is some SQLIO test data over here. I think it is inconclusive based on the test systems except that SSD totally excels at random reads which should be the bulk in an OLTP workload. The EVA on server 2 is a > $150k SAN. I would like to see how 20-30 striped SSD drives with a stout controller compare write-wise. The tests also do not mention disk caches and raid controller caches which should also be configured to optimize writes since sql uses the RAM as read cache.
