Press Esc to cancel. But most double disk failures on RAID 5 are probably just a matter of one faulty disk and a few uncorrected read errors on other disks. What does a RAID 5 configuration look like? 2 Making statements based on opinion; back them up with references or personal experience. Because data and parity are striped evenly across all of the disks, no single disk is a bottleneck. The diagram in this section shows how the data is distributed into stripes on two disks, with A1:A2 as the first stripe, A3:A4 as the second one, etc. suppose we have 6 disks. k Our example from earlier shows a left-to-right asynchronous layout, but this can change depending on certain factors. [1] The numerical values only serve as identifiers and do not signify performance, reliability, generation, or any other metric. p {\displaystyle GF(m)} With a 5 way, 3B RAID this becomes almost inevitable when a rebuild is needed. This means each element of the field, except the value These stripes are interleaved in a repeated sequential manner. RAID 6: RAID 6 needs at least 4 drives. {\displaystyle i
