Benchmarks: RAID 1 Via eSATA And USB
The SansDigital Mobilestor MS2UTN+ caused a few problems during our test. Hot-plugging did not work properly, and the drive configuration was only recognized after a restart, although the JMicron JMB363 controller we used supports both hot-plugging and port multiplier functionality. The problems were particularly troublesome with the RAID 1 configuration.
During the rebuild, the MS2UTN+ signaled that one of our Samsung HD321KJ drives was defective. Even replacing the drive with another Samsung HD321KJ known to be fully functional was not sufficient to solve the problem. We eventually managed to get it to work with two Western Digital Raptor disks (model WD360), which explains why the graphic shows the overall capacity as being 37 GB. The other modes worked with the Samsung disk with no trouble at all. After speaking to the manufacturer, we discovered that Samsung disks are not compatible, but this information is not included in the manual.
The most impressive performance in this test was delivered by the Fantom Drives G-Force Megadisk MDE1000. With an average 80.9 MB/s read speed and average 76.5 MB/s write speed, it was the fastest of the three tested devices.
A similar result was seen when connecting via USB. Here, however, the Fantom Drive G-Force Megadisk MDE1000 and the Superbox /Jou Jye ST-2320S/UES were just about equal. The ST-2320S/UES provided more impressive steady-state performance.
