RAID 0 Benchmark Results: SSD vs. Conventional Drives
As already mentioned, we also compared four of the Memoright Flash SSDs in a RAID 0 array. We used four Seagate Savvio 10K.2 drives as well as four Western Digital WD1500 Raptor drives. We regret that we did not yet have access to four VelociRaptor drives, which would have been an even better comparison, as four of them roughly equal the cost for one 32-GB Memoright MR25.2-032S.
Streaming Read Performance (RAID 0, 4 Drives)
The Memoright Flash SSD RAID 0 array constantly writes 460 MB/s, while the conventional hard drives are limited to less than 350 MB/s. It’s obvious that the new VelociRaptors could come close to this excellent result, but they most likely won’t beat it.
Streaming Write Performance (RAID 0, 4 Drives)
Streaming write performance is similar. It is important, though, to be aware that the controller cached most of the writing operations, hence the graph is somewhat inflated. The result of 430 MB/s at single commands (Q1) is realistic.

At that price I will stick to my hard drives. These SSD devices have a long ways to go before the average pc user feels the need to dish out hard earned money for them.
It's good to see that SSd drives are at the point that HDD were about 10/15 years ago. Give these another 10 years (if even) and we'll be laughing about how we used to use HDD for storage.
should of tested RAID 5 as well and maybe raid 1, but i guess the numbers would of been lower mosty due to the fact the RAID card mite not be able to keep up with the SSD drives lol
i think ssd drives will not take 10 years to come top dog in the hard disk market think more like 3-5 years maybe even less
I was under the impression that SSD are limited in the number of times you can perform write operations to them. I'm sure that I read an article that said a SSDs life expectancy would severely diminish with an OS continually writing and rewriting temp files to it?
Two years max before all enthousiasts have an SSD drive in their PC's. Not to replace the HDDs, but a small one (32GB or 64GB sounds about right) just for the OS, applications and some games.
