Table 1: Feature summary


Performance tests were run using our Revision 5 NAS test process on four-drive unencrypted RAID 0, 5 and 10 volumes using WD Red 3 TB (WD3000FYYZ) drives with a 1 Gbps LAN connection. The firmware installed was DSM 5.0-4493 Update 3.

The DS415play's Benchmark Summary below shows Windows File Copy read and write performance slightly above 100 MB/s for RAID 0 and RAID 5. However, the RAID 10 file copy write performance was only about 75% of the RAID 0 file copy write performance. In all cases, RAID 10 performance was lower than the corresponding RAID 0 and RAID 5 performance.

For all RAID levels, NASPT File Copy Write Performance was faster than the corresponding File Copy Write Performance. NASPT reads were slower than the corresponding File Copy reads.
