Netgear RD521210 – ReadyDATA 5200 12TB SATA Bundle includes RD5200 with 2 x RD5D6LT01 Disk Packs Quick Setup Guide

NETGEAR makes the following general recommendations: 

For a volume that is used for random reads and writes, use SAS drives.

If high I/O performance is required, do not use RAID 5 or RAID 6.

For applications that require low latency and high performance, use SAS drives in a 
RAID

 

10 volume. Examples of such applications include virtual servers (VMware, 

Hyper-V, XenServer), databases, email, video, and processing.

For general file serving, use large-capacity SATA or NL-SAS drives in a RAID

 

5+0 volume 

with SSD read and write caching boost disks.

For disk-to-disk backup, use large-capacity SATA or NL-SAS drives in a RAID

 

5 or 

RAID

 

6 volume with a maximum of 12 drives per RAID group.

HDDs differ in capacity, performance, and price. The following table compares hard disk 
drives, storage capacity, and performance in a RAID

 

5 SAN volume.

Serial ATA drive 
7,200 rpm

1 TB, 2 TB, 3 TB, 
and 4 TB

Low

SATA disks offer large storage capacity and are 
a good compromise between price and 
performance.

Serial attached 
SCSI drive 
15,000 rpm

300 GB, 450 GB, 
and 600 GB

High

SAS disks show a stronger performance than 
SATA disks but offer more limited storage 
capacity.

Serial ATA 
solid-state drive

50 GB, 100 GB, 
and 200 GB

Highest

SSD disks outperform SATA and SAS spindle 
disks but are more expensive and offer limited 
storage capacity. SSD disks can be used as 
boost disks in a hybrid volume.
