RAID5-level data
storage
A RAID that provides data striping at the byte level and also stripe error correction information.
RAID5 configurations can tolerate one drive failure. Even with a failed drive, the data in a RAID5
volume can still be accessed normally.
RAID6-level data
storage
A RAID that provides data striping at the byte level and also stripe error correction information.
RAID6 configurations can tolerate two drive failures. Even with two failed drives, the data in a
RAID6 volume can still be accessed normally. RAID6 read performance is similar to RAID5, since
all drives can service read operations, but the write performance is lower than that of RAID5
because the parity data must be updated on multiple drives.
