- RAIDfail: Don't use RAID 5 on small arrays
- Big storage companies stopped recommending RAID 5 a couple of years ago. But I still see small 4-drive arrays touting RAID 5 for home and small office use. Big mistake. You want to save money, but you also want to keep your data. RAID 5 isn't...

- Sorry about your broken RAID 5
- Sorry about your broken RAID 5Still trying to understand your argumentGranting that a URE rate of 10^-15 [1] means that the incidence of two UREs per array approaches unity once the storage system exceeds 10^30 sectors (10^39 bytes, which is a rather large array), what isn't clear is why this...

- RAID 1+0 is the Cadillac of RAID
- RAID 1+0 is the Cadillac of RAIDNo performance differenceFirst of all, most people tell me RAID10 (1+0) is better than RAID 0+1, but only in the sense that RAID10 has better degraded performance where one of the drives have failed. No one ever claims that RAID10 is faster than...

- RAID 1+0 is the Cadillac of RAID
- Is RAID 1+0 superiority a myth?My fellow ZDnet blogger, George Ou, makes some strong statements, bolstered by damning performance numbers, that it is.
