It can be designated as a Left Asynchronous RAID 5 layout [24] and this is the only layout identified in the last edition of The Raid Book [25] published by the defunct Raid Advisory Board. [26] In a Synchronous layout the data first block of the next stripe is written on the same drive as the parity block of the previous stripe.
RAID 10, also called RAID 1+0 and sometimes RAID 1&0, is similar to RAID 01 with an exception that the two used standard RAID levels are layered in the opposite order; thus, RAID 10 is a stripe of mirrors. [3] RAID 10, as recognized by the storage industry association and as generally implemented by RAID controllers, is a RAID 0 array of ...
Given the dynamic nature of RAID-Z's stripe width, RAID-Z reconstruction must traverse the filesystem metadata to determine the actual RAID-Z geometry. This would be impossible if the filesystem and the RAID array were separate products, whereas it becomes feasible when there is an integrated view of the logical and physical structure of the data.

With its "far" layout, MD RAID 10 can run both striped and mirrored, even with only two drives in f2 layout; this runs mirroring with striped reads, giving the read performance of RAID 0. Regular RAID 1, as provided by Linux software RAID, does not stripe reads, but can perform reads in parallel. [29] [30] [31]
RAID 4 – Like RAID 0, but with an extra device for the parity. RAID 5 – Like RAID 4, but with the parity distributed across all devices. RAID 6 – Like RAID 5, but with two parity segments per stripe. RAID 10 – Take a number of RAID 1 mirrorsets and stripe across them RAID 0 style.
