Re: RAID Flavours, and what they mean. Are there any new benchmark comparisons for RAID 5 vs RAID 0 and RAID 0+1? The big bottleneck of RAID 5 used to be the parity calculations, but all of the benchmarks that I've seen are 2+ years old. Even a moderate machine (Intel Core 2 Duo E8500 on a Mobo with an onboard RAID controller) could easily outstrip the test machines in those older benchmarks. Theoretically, RAID 5 should offer some of the best read/write speeds with data protection. Are we there yet? Can the hardware handle the parity calculations quickly enough yet? Are there any current benchmarks confirming or refuting the idea that RAID 5 is actually "good?"
