Not to mention the "write hole" where a single write requires 4 reads on RAID5. RAID0+1 provides better write speeds because less compute and fewer reads are needed.
Striped RAIDs are a thing of the past. The closest we could come today is, effectively, "spanning datacenters".
- yellowapple 11y agoWorth mentioning that RAID1+0 and RAID0+1 are two different things (striped mirrors versus mirrored stripes, respectively), and have two different probabilities of multi-drive failure causing total array failure (long story short, RAID10 has a better chance of surviving a multi-disk failure than RAID01 without any sacrifice in capacity or performance). But yes, the performance boost is certainly quite fantastic.
