    sata is also not available in 15k edition, so maybe he is mistakenly writing scsi as sata.

    IMHO, if you want to use RAID1, raid in software is allright. If you want to use RAID5, you can try the 3ware cards, I heard quite some good things about it. Also, SATA is always cheaper, and nowadays, with SATA2, you have same performances (if not better) than with SCSI.

    Hello, If you want a high performance go for RAID10, If you want redundancy go for RAID1, and forget RAID5 its the least performing RAID, only a better solution then JDOB it will hinder all IO performance.

    RAID10 is best bet IMHO since VPS node means lots of people are going to use it for their heavy stuff.

    That's why I was saying RAID5 is to be used in hardware. It takes a lot of CPU to calculate parity, and I would not do it in software. When in software, RAID0 doesn't take more CPU or I/O, and RAID1 takes only twice the I/O (but no more CPU).
