The Velociraptor isn't that hot. But yeah, with the upcoming Vertex 3, a single Vertex 3 will outperform two Velociraptors in RAID-0 on every single factor (sequential, random, access time), except capacity.

Lots of writes? Shouldn't that still be in an SSD's domain? If it is about the write life span, that shouldn't be a concern, unless your server sees more than 50GB of writes a day.

That article was from more than two years ago. There have been great strides in SSD performance since then. As for RAID, there is the option of buying Kingston's V+100.

I haven't, not in a position to be able to afford such a test. Still, what are you basing your opinion on? The Velociraptors loses out on access time, random and sequential speeds. How can it be better for enterprise needs?

Also, enterprise needs vary from application to application. Some applications are mostly reads and rarely does any writing. And I wouldn't be surprised if this active and massive forum could happily live on MLC-grade SSDs. It takes a lot to hit 10GB of daily writes and Intel's SSDs are rated for 100+GB writes/day.

TRIM really isn't necessary to maintain performance, as Kingston's V+100 has shown by sacrificing some lifespan to keep a high performance.
