Netgear RD5200 (ReadyDATA 5200) – ReadyDATA 5200 System Empty Chassis with 10G (2 port SFP+ card) Quick Setup Guide

All following volume examples use 1

 

TB SATA disks and have deduplication disabled.

RAID 10 (also referred to as RAID 1+0) supports both striping and mirroring and provides the 
highest performance. The drawback is the number of disks that you need for this 
configuration: You require one dedicated parity disk for each storage disk. 

The following figure shows a volume that is configured for RAID 10 with six storage disks and 
six parity disks:

RAID 5+0 supports striping across multiple volumes during expansion. RAID 5+0 provides 
good performance but requires a smaller number of disks than RAID 10 because parity is 
distributed across the storage disks. Part of the storage space on each disk is sequestered 
and dedicated to parity.

The following figure shows a RAID 5+0 x4 volume with three disks that have been expanded 
three times for a total of four RAID groups:

A RAID 5+0 volume with a single SSD write (log) boost disk and two SSD read (cache) boost 

disks increases the performance for the sequential IOPS. Compared with a RAID 10 volume, 
the writing performance is increased; compared with a regular RAID 5+0 volume, the reading 
performance is increased.
