provide the best write performance?
Maybe D. RAID 10 splits data across disks without parity overhead, so it avoids the slowdowns that RAID 5 and 6 face during writes. RAID 3’s single parity disk can also cause a bottleneck.
D, since RAID 10 just writes data twice without complex parity calculations.
It’s D since RAID 10 avoids parity, so writes don’t get bogged down like in RAID 5 or 6.
Writes slow down on RAID 5 and 6 because of parity calculations, so those are out. RAID 3 also has a dedicated parity disk, which can bottleneck writes. D is the best choice here. D
D vs B? RAID 5 has to do parity calculations which slows writes, so RAID 10’s mirroring plus striping should definitely boost write speeds more. Parity overhead kills performance here.
Maybe D. RAID 10 avoids parity overhead, so writes don’t get bottlenecked by calculations or a single parity disk, unlike RAID 3, 5, or 6. That usually means faster write speeds.
I think D, RAID 10, gives the best write performance since it stripes and mirrors without the parity calculations needed in RAID 5 or 6. RAID 3 uses byte-level striping with a dedicated parity disk, which might slow writes compared to RAID 10. Anyone else agree?
