My interest was in the peak reading so I could figure out which of my UPS would be able to take it. I got those readings with a Kill-A-Watt EZ (paid link). This is something to research on the Mediasonic forum.Ġ.3 watts with power brick plugged in (Vampire Power)
I could have sworn the laptop and desktop were setup for AHCI mode on the BIOS of at least the HP. Later I would discover that it would shutdown correctly on eSATA for a Synology DS412+. I tested it with my Lenovo W520, HP Elite 380T and Zotac IONITX-A-U but the unit did not power down while hooked up to either eSATA, USB 3.0 or USB 2.0. The ProRaid is supposed to power itself down when the host computer shuts down. The source disk for the test contained thousands of photos, videos and sound files which were stock material for video editing. I'm not too disappointed since that's still faster than my Samba server which I use presently. I guess I'll take it as a low end baseline for ProRAID. The CrystalMark test is still at odds at the above results. But that's an apples to oranges comparison. It seems a far cry from the Software RAID 0 setup previously tested.
Spindles will barely reach the limit of even SATA 1.0 (1.5 Gbps / 192MB/sec) bandwidth.Ī Robocopy write test was much slower at 28.11 MB/sec. Which is fine since the enclosure is meant for 3.5" mechanical hard drives. The ProRaid shows up as a SATA II (3.0Gbps / 384MB/sec) device. As in, no drives should be inserted until it is RAID confirmed and powered down. The trick is to setup the RAID mode with the ProRaid empty. If the drives need to be migrated to another ProRaid unit, you're supposed to be able to use them in the same RAID mode. And any content will be lost once it has started up. The device will be uninitialized if the drives have never been used in that RAID mode before. Next time you power up the RAID mode is set.
Remove the tab covering the RAID confirmation button next to the power plug. Press mode several times to select the RAID type. The instructions are explicit, hold down the mode button for 3 seconds until the RAID mode flashes. The unit will immediately flash the red H icon after spinup if a RAID setting has not yet been selected. Even after reading the manual it caught me unawares at first.
