The EN104L+ was tested with our standard NAS test process with 1.090707k3 firmware and four Hitachi HDT721010SLA360 Deskstar 7K1000.B 1 TB SATA drives shipped with the NAS. Tests were run with 1000 Mbps and 1000 Mbps w/ 4K jumbo frame LAN connections with four-drive RAID 0, 5 and 10 arrays, formatted with XFS and default 64 KB block size.

As I promised, I'm keeping track of volume build times. For a 4 TB RAID 5 volume and with Rebuild Speed set to High (Medium and Low are the other options), it took 4 hours, 20 minutes to create and fully sync with no other NAS activity.

Figure 10 presents a summary of the write benchmark tests. There is some moderate cache boost for files up to around 256 MB. Write performance with a 1000 Mbps LAN connection averaged over the 32 MB to 4 GB file sizes and with cached results above 125 MB/s removed from the average measured 75.3, 77.3 and 79.9 MB/s for RAID 0, 5 and 10 writes, respectively. Both the RAID 5 and RAID 10 results represent new NAS Chart highs.

Figure 11 shows the average read performance for the same test configurations which came in lower at 64.9, 62.1 and 64.8 MB/s for RAID 0, 5 and 10, respectively. None of these represent new chart highs.

Performance - File Copy

Vista SP1 filecopy results (Figure 12) for RAID 5 write show the EN104L+ in fifth place, with 68.1 MB/s average write speed.

Although RAID 5 read filecopy is a bit slower at 61.3 MB/s, more of the competition is faster. So the EN104L+ came in at 12th place in the ranking.
