Volume Performance and Configuration on ReadyDATA Platforms
Sequential Read and Write Performance on SAN Volumes
The following figure shows that a RAID 5 volume with SSD disks provides the best overall
performance for sequential reads and writes. A RAID 5+0 x4 volume with SSD disks and a
RAID 10 volume with SAS disks provide good alternatives.
performance for sequential reads and writes. A RAID 5+0 x4 volume with SSD disks and a
RAID 10 volume with SAS disks provide good alternatives.

Hard Disk Drives and RAID Performance on a NAS Volume
While pure SSD volumes always outperform volumes with spinning disks such as SAS or
SATA disks, pure SSD volumes are usually not practical because of high cost and capacity
limitations. Taking cost and capacity into consideration, SAS drives in a RAID 10
configuration provide the best all-around performance for NAS volumes. NETGEAR strongly
recommends using SAS drives in a RAID 10 configuration for virtualization and storage
application that requires high IOPS, low latency, or both. For applications that do require high
IOPS such as general file serving and backup applications, SATA drives offer a high-capacity,
low-performance alternative.

Drag and Drop Performance on NAS Volumes
The following figure shows that a RAID 5 volume with SSD disks and a RAID 5+0 4x volume
with SSD disks provide the best overall D&D performance. A RAID 5 volume with SAS disks,
a RAID

a RAID
5+0 4x volume with SAS disks, or a RAID 10 volume with SAS disks provides a good
alternative.
