Below you can see the results for the “I/O Comparison” test using 128 KB blocks, given in KB/s. “Local” means the performance achieved by reading the drives locally and “Remote” means the performance achieved by reading the drives from another computer on the same network, thus simulating the typical configuration found on home and small offices, where files are read from another computer located at the same network. “Single” is obviously only one drive (Seagate 7200.10 160 GB) while our local/remote RAID0 configuration was built based on Intel ICH9R using two Seagate 7200.10 160 GB. On all NAS we installed these two drives in RAID0.

On this test Thecus N5200 was the fastest NAS box, being 48% faster than Thecus N3200 and 108% faster than Promise SmartStor NS4300.

A RAID0 array created and shared on a regular PC was 23% faster.

Of course you can’t expect to achieve the same performance as if the disks were installed locally. Our local RAID0 array was 222% faster than the one built with Thecus N5200.

On write performance Thecus N5200 presented an impressive performance, similar to a RAID0 system shared from a regular PC. It was 116% faster than Promise SmartStor NS4300 and 128% faster than Thecus N3200.

Once again don’t expect to achieve the same performance as if the disks where installed locally. Our local RAID0 array was 255% faster than the one built with Thecus N5200.
