performance should be good? I assumed it was an analog to RAID-6. In our recent experience RAID-5 due to the 2 reads, a XOR calc and a write op per write instruction is usually much slower than RAID-10 (two write ops). Any advice is greatly appreciated.
RAIDZ and RAIDZ2 does not suffer from this maladay (the RAID5 write hole).
