Review: Snap Server 520
This NAS was the best performer of the lot. The device runs Linux based
Guardian OS, and has a simple and easy to understand Web interface for
management. It also has a LCD display. Interestingly, its OS takes 10 GB space
on every hard disk, which ensures that the server will keep running even if two
or even three of the hard drives fail. It ships with 4 x 250 GB 7200 RPM
hot-swappable SATA drives and 512 MB RAM, which can even be upgraded to a good 4
GB. The device also ships with a Manager application, which is useful only if
you're running multiple Snap Servers in your data center.
The SnapServer can also work as an FTP or a Web server, and supports CIFS,
SMB, NFS and AppleTalk file systems. It also has plenty of monitoring
capabilities from regular system monitoring, users monitoring, open files
monitoring to iSCSI device monitoring. The box shipped to us with CA Antivirus
pre-installed, and even BakBone NetVault software for taking backups to tape
drives. The box also supports taking snapshots and there's even an option to
create a single image of its configuration and all its data. This can be great
for DR purposes, as you can simply copy the image to another storage device or
tape drive. After configuring RAID 5, the available storage capacity on the
server comes down to 691 GB.

| ^ IOMeter: I/Os per second |
On the performance front, like we said, it gave excellent results. It scored
a whopping peak throughput of 608 Mbps in NetBench, and that too with 15 clients
(whereas others peaked out at 5 clients). Even beyond 15 clients, its throughput
remained higher than the other NAS boxes. In IOmeter, the I/Os per second it
recorded for both 64 K and 128 K request sizes were the highest in sequential
reading and writing of data. In transferring 100 GB of data, it only took 73,
which was the fastest among all NAS boxes reviewed. Likewise, transferring a
compressed ISO image of the same 100 GB of data was also the fastest at 44
minutes.
