    I currently have a RAID5 array of 4 drives, and a separate raptor I use for the OS. I wanna replace the raptor with 2 128GB SSDs, and run them in RAID0. Can I have a raid0 and raid5 array at the same time with the mobo raid controller?

    I have Asus Formula mobo

    No you don't, you want to run one array in RAID5 and the other in RAID1. And yes it can be done.

    You should be shot for even mentioning RAID0

    No, I wanna run them in RAID0. I need speed. All my important data is/will be on the RAID5. RAID0 is for system only. Secondly, SSD is way more reliable than an HD. Even if it does fail, the only thing Im gonna lose is the OS installation + some programs.

    werd. I'm pricing out a similar server for a shitty asp app I need to manage. I really hope this shit takes off so buying this faggotry will be justified by my being able to live in Paris for a year like I want to. ugh.

    Make sure you check out the speed ratings of the different SSD's, from what I've read, the Intel X25 is the only one worth the money, and that said, it's a lot of money compared to the other drives out there. NCIX does have it on sale this week for $375 for the 80GB one.

    OCZ Vertex' are good drives as well, especially the 120GB/250GB.

    If you're using *nix, there are some special I/O options in the kernel that work the best with SSDs. Consider using the NO-OP scheduler.

    You'll still get 2x the read speed with RAID1. Write speed should be a non-issue because both the RAID controller and the SSDs will have RAM buffers in them.

    Intel still has the fastest drives from what I've seen, and Samsung is in second place.

    lol, just like the last SSD thread. Samsung still doesn't have a drive that performs as well as either the OCZ Vertex or the Intel X25-M/E. Reason being they are still making sub-par controllers. Even the new controller they just released (used in OCZ Summit) isn't as good. And the previous gen Samsung drives get absolutely creamed by anything else.
