Hands On

Once the EDR was configured, I had no problems finding it on my Windows network. I was surprised, however, that with only the default “guest” user defined, when mapping a drive, I had to click to open the device and use the guest/guest login credentials. Most of the other NASes I’ve reviewed allow a guest connection to the public share without authentication. Of course, if your user account on the NAS matches your windows name and password, you won’t have any problems.

I tried accessing the EDR via FTP. The EDR allows up to eight connections, but doesn’t support anonymous FTP. FTP clients such as WS-FTP won’t have any problems, but for browser-based access, you’ll need to use the following format: ftp://username:password@IP_Address.

I plugged in several USB drives, which the EDR immediately recognized and had no problem mapping drives to them.  By default, no users are assigned to USB shares—you have to add users to the USB shares before they can be used on the network.

The real measure of a NAS that supports RAID is how well it handles a disk failure. Do you lose your data? What happens if a drive goes bad? What happens depends on how you’ve configured the RAID. To demonstrate this, I created a test scenario which I’ve documented in a separate slideshow.

Initially, the EDR was configured for RAID 10 and 100% of the space was allocated for shared folders. I set up users, groups and shares and copied data. I also tried to use the backup software to protect a partition on one of my systems, but the backup failed because there was no unallocated space on the RAID.

I then decided to reconfigure the RAID for RAID 5 + Spare. In this configuration, data and parity are striped across three drives, and the fourth drive is online as a spare, should any of the three drives fail. As warned, I lost all data when I reconfigured to RAID 5 + Spare.

The RAID array reconfigured fairly quickly, and I had access within minutes, albeit at reduced performance. However, the EDR took more than 14 hours to fully synchronize the new array and restore full performance! Note that if another drive failure occurs while an array is being resynced, you lose all data.

Once the RAID 5 + spare configuration had synchronized, I copied additional data to the drive and successfully backed up a notebook partition to the EDR. I then intentionally failed the drive in bay one by pulling it out. I still had access to my data, and was able to continue to back up my notebook partition. 

Immediately after pulling the bay one drive, the spare drive in bay four started rebuilding. 13 hours and 23 minutes later, the new drive had synchronized and the RAID was again fault-tolerant.  I then re-inserted the original “failed” spare back into slot one.  Immediately the EDR recognized the drive and designated it as the spare.

Under the Advanced menu, the Disk sub-menu shows the model, serial numbers, size disk status and a “hot plug” indicator for each drive. A green hot plug indicator means that removing the drive will have no impact on the RAID. Yellow indicates that removing the drive (or if it fails) will cause the RAID to operate in a degraded state. Red means that the RAID will fail and data loss will occur if the drive fails.
