Due to a needed performance increase I bought a DS710+ and compared performance between the 2 (CS407 vs DS710+).

Harddisk and RAID configuration:

CS407: RAID 5 with 3 Western Digital WD5000AAKS 500GB

DS710: Synology Hybrid RAID (SHR) with 2 Western Digital WD2002FYPS 2TB

For both Synology NAS DSM version 3 .0-1354 was in use – configuration of the 2 was basically comparable (SMB only, NFS, Media Server)

On client side I used a Windows 7 Ultimate 64bit with an Intel 80GB SSD.

The test was accomplished with Intel’s NAS Perfomance Toolkit; also interesting to read Smallnetbuilder

Here are the results:
