Features

The DL2100 has the same administration user interface as the DL4100.

The DL4100 review covers the DL2100's features, too. The only difference is that only JBOD, span, RAID 0 and 1 are supported because of the two-drive limit. Since WD's use of JBOD is a bit different, I showed the screens for it and Spanning modes below.

I'm happy to report that the flaky behavior of the WD My Cloud remote access features via the My Cloud apps seems to have vanished. I had no problem with the apps finding both my office single-drive My Book Live and the DL2100. I was able to access them via an Android tablet connected to my WLAN and a Moto X Android phone via cell connection.

Performance

The DL2100 was tested with 1.06.118 firmware using our Revision 5 NAS test process. The DL2100 tests used two drives configured in single RAID 0 and 1 volumes. All tests were run using Western Digital Red 6 TB (WD60EFRX) drives (x2 factory installed).

The Benchmark Summary shows the Intel Atom does a pretty good job of making the most of a single Gigabit Ethernet connection. But there is one hiccup. Windows File Copy results are consistent between RAID 0 and 1, but the NASPT RAID 1 File Copy from NAS (read) benchmark is much slower than write at 74 MB/s vs. 105 MB/s.

WD My Cloud DL2100 Benchmark Summary

Our published results are based on the average of three test runs. Checking the data I found the first NASPT RAID 1 File Copy from NAS test run could not read the test file so returned a 0 result, which brought down the three-test average. I repeated the benchmark run three times and this behavior was consistent. The other two test runs yielded throughput of 111.4 and 111.0 MB/s.

The NAS Ranker slots the DL2100 in fourth place, behind the QNAP TS-251 and TS-253 Pro tied for third and ahead of ASUSTOR's AS-302T ranked #5. Sorting by ascending price, the diskless DL2100 ties with the #2 ranked AS5002T at $350.

Comparing NAS Ranker performance summaries for the two equally priced products shows the ASUSTOR with generally higher write performance, about equal for read and much better for mixed video record / playback, iSCSI and backup. So the ASUSTOR's dual-core, 2.4 GHz Intel J1800 Celeron seems to make a significant performance difference.

Closing Thoughts

The My Cloud DL2100, like the My Cloud DL4100, has a combination of performance, features and brand-name recognition that should move a lot of NASes off the shelves. But lesser known (at least among average consumers) QNAP and ASUSTOR products offer better value. WD still rates highest in my book for easy to use remote access / personal cloud use, however.
