Features - more

I found a few changes in features, which I'll describe briefly. Data Guard was added in November, announced primarily as a remote backup solution. But it also handles backup to and from attached USB/eSATA drives and also internal folder-to-folder backup.

Despite the addition of Data Guard, attached backup throughput is still not one of Thecus' stronger features. I used it to perform my attached backup tests and wasn't impressed. I was only able to create one backup profile and could not rerun it. Throughput, as you'll see later, wasn't that impressive, either.

Data Burn was announced in May and is what you would expect from the name, i.e. support for saving data to CD, DVD, and Blu-ray discs. Thecus doesn't provide a list of supported drives. But the Samsung SE-S084 USB drive I attached was recognized.

I checked the supported module list using the Auto Module Installation admin menu and came up with modules shown below. Comparing against the most recent previous version of the list shown in the N6850 review, I found the HiSSH module removed, but still available from the N7150's module download page. You don't really need the module, however, since an SSH enable has been added to the Network Service menu. The SSH menu also lets you set the port number and enable support for SFTP, which clients like WinSCP support.

New modules were Local Display (reviewed) and a Transcoding Service module. The latter supports Thecus' T-OnTheGo feature that allows file up/download and multimedia playback for iOS devices. I did not try this out. Note that you have to go to the download page to get and install the T-OnTheGo module that must be installed with the Transcoding service. Note also that Thecus does not specify the file formats that the transcoder supports.

The gallery below has screenshots of many of the features referenced above.


I tested the N7510 with 2.03.08.cdv firmware, using our NAS test process with RAID 0, 5 and 10 volumes. As is our standard practice, four drives were configured in each volume type.

Windows File Copy tests show read throughput running 10 - 15 MB/s lower than write for all tested RAID modes. Highest write throughput measured was 107 MB/s for RAID 0 and highest read was 90 MB/s also in RAID 0.

As we have seen in other recent reviews, Intel NASPT File Copy results run about 20 MB/s higher for write and roughly the same for read. Highest write throughput of 128 MB/s was again in RAID 0; highest read was 86 MB/s in RAID 10. Keep in mind the maximum theoretical throughput with a Gigabit Ethernet connection is 126 MB/s. So results higher than that have some write cache effect baked in.

iSCSI performance of 86 MB/s for write rank the N7510 about mid-chart and 80 MB/s for read move it up into the top third of all NASes tested.

Attached backup tests were run with our standard Startech USB 3.0 eSATA to SATA Hard Drive Docking Station (SATDOCKU3SEF) containing a WD Velociraptor WD3000HLFS 300 GB drive. Best backup throughput of 60 MB/s was obtained using USB 3.0 and a FAT-formatted drive.

Network backup to a DeltaCopy target on our NAS Testbed system measured around 37 MB/s. For comparison, best network backup measured to date has been 44 MB/s with a NETGEAR ReadyNAS Pro 2.
