As I mentioned earlier, the se supports all the features in Synology's current DSM 4.3 OS. Our most recent look at the DSM feature set is Scott's DS713+ review. We'll will be doing a full review of the DSM 4.3 operating system in the near future. In the meantime, here are a few screenshots to give you an idea of what DSM 4.3 looks like.

You can also give it a test drive using Synology's read-only Live Demo.

The DS214se was tested with its factory-installed DSM 4.3-3781 firmware using our standard NAS test process to run tests with two-drive RAID 0 and RAID 1 volumes. The drives used for testing were the two 2 TB WD Reds (WD20EFRX) that Synology supplied.
The benchmark summary below shows very evenly-matched Windows File copy performance between RAID 0 and 1 volumes with mid 50 MB/s writes and low 90 MB/s reads. Switching to the NASPT File Copy benchmarks moved writes up to 90 MB/s or so and reads down to 80 MB/s. But once again, there was little difference between RAID 0 and 1.

Synology didn't like our initial performance results since they fell far short of their specified 58 MB/s write and 102 MB/s reads. After a few rounds of test runs, Synology found the source of the difference.
It turned out that we ran our tests with a browser logged into the Synology admin "desktop". Even with the System Health / Resource Monitor widget closed, there apparently is enough processor load to limit read throughput to the mid 80 MB/s range. So if you want top performance, stay out of the admin interface! That's what we did when we retested to post updated results that now reside in the NAS Charts.
It's somewhat hard to believe that you'd find two-bay NASes in this price class that support iSCSI, but there are several of them. The filtered chart below summarizes iSCSI write performance for two-bay NASes with single-core application-specific processors. The DS214se does pretty well with 48 MB/s writes. The se does a little better in the filtered iSCSI read chart, coming in at the #2 slot with 53.7 MB/s.

Attached backup tests yielded a best backup throughput of 22.3MB/s using a FAT-formatted drive and worst throughput of 15.3 MB/s with a NTFS formatted drive. These tests were run on USB 2.0. Unlike the $140 Zyxel NSA320 and the Buffalo LS421e, which have USB 3.0 ports, the DS214se has only USB 2.0 ports. Network backup to our standard rsync target clocked in at 19 MB/s.
