PCIe SSD RAID 0 solution ?

Fernando,

What do you think about PCIe SSD RAID 0 solution in term of performance ? , Easy to install ? an reliability ?

Do you this technology will replace soon SATA 6G RAID 0 SSDs solution for PC Desktop Consumer ?

Theoretically this will give you the best possible RAID performance, but the PC has to support booting off PCIe lanes.

I don’t know, because I am no clairvoyant. The future development of RAID systems doesn’t just depend on what is the best, but on the price and the consumer’s acceptance as well.

I see as example the Mushkin Scorpion Deluxe solution using a LSI driver (W8 or W7 , etc) to support booting off PCIe lanes with 2.15 GB/s (R) and 1.95 GB/s (W) 240 GB SSDs.
Yes, price/performance ratio is determinant.



First and foremost, RAID0 is zero data protection. If you want your data safe at all, it’s a non-starter. It just flat out isn’t. Single block error on RAID0 == data trashed. Optimally you want to be RAID0+1 or RAID10 for data safety.

The numbers cited above are buffered and false. Scorpion Deluxe is smoking, sure, but depends on what LSI controller exactly and so on. The fact is that you can buffer anything to oblivion to cook the books. You’d likely see better IOPS out of a Chronos Deluxe 240 (same as I do) because of NCQ. The numbers if you connect them to proper RAID, e.g. LSI SAS (Dell PERC 6i, HP P410/P411/P412) go stratospheric quickly. And it’s cheaper.

But either way, you’re booting Windows. So frankly, you’re not getting crap out of them. They can only service requests. You’re highly unlikely to make enough requests to actually strain anything decent. I can’t even get my Chronos Deluxe 240 warm till I’m literally hammering it as hard as I can with incompressible random writes.
