After unpacking the D-Link DNS-320 i checked the performance of the DNS-320 in the Network. All these measurements were done in my home environment so be careful to see them as representative. Werbung
The transfers are initiated from a pc with a onboard gigabit network adapter over gigabit-ethernet with a D-Link DGS-1005D as a switch in between (no other clients active). Two Seagate 500GB 7200rpm-harddrives are used for storing the data in the NAS. The NAS with Firmware 1.00 gets set back to factory settings and the harddrives are formatted before every test which disables all server software except the samba server (for the network shares). I transferred a dummyfile with 1,5GB size once with windows 7 copy functions and once with TeraCopy. In all cases the transfer rates between the two tools didn’t differ.
|ext3 – Single Disks||25MB/s||30MB/s|
|ext3 – RAID 0||24MB/s||36MB/s|
|ext3 – RAID 1||23MB/s||29MB/s|
JBOD got the same results as single disks.
D-Link created a NAS with reasonable performance, even when using RAID. The difference between the different modes is nearly not visible. The user can choose between them with only looking at the data integrity/security and not at the speed.
