Since the C200 is a real NAS (unlike the Cloudplug), I tested with our standard NAS test process with firmware and two Hitachi 0F10379 DeskStar 7K1000.C 250 GB drives. Tests were run with 1000 Mbps and 1000 Mbps w/ 4K jumbo frame LAN connections with RAID 0 and 1 volumes.

Figure 6 presents a summary of the iozone-based benchmark tests run for the C200. Write cache boost for both RAID 0 and 1 is moderate, saying below the Gigabit LAN connection's 125 MB/s theoretical limit. Write and read erformance with 512 MB and larger file sizes runs in the mid 30 MB/s range, except for RAID 1 writes, which drop to the mid 20s.

Performance benchmark summary

RAID 1 Write performance with a 1000 Mbps LAN connection averaged over the 32 MB to 4 GB file sizes and with cached results above 125 MB/s removed from the average measured 49.6 MB/s and reads averaged 41.6 MB/s.

Performance - File Copy

File copy tests always provide a bit of a different view of NAS performance and the C200 is no exception. Figure 7 shows how the C200 ranks for RAID 1 writes, coming in at essentially the same as another 1.2 GHz Kirkwood box, the QNAP TS-219P. The QNAP did better for RAID 1 reads, however, coming in at 50.9 MB/s vs. 42.4 for the C200.

I didn't test backup performance to a USB drive, but I'd expect it to be in the 20 MB/s range for an EXT3 formatted drive. I did happen to run a file sync of a CIFS share with about 1.3 GB of assorted files and folders via a Gigabit Ethernet link and the log showed that it ran at a rate of about 3 MB/s.

Closing Thoughts

The bottom line for the C200 is similar to Jim Buzbee's conclusion for the Cloudplug. The user interface is nicely done and has some features that other vendors would do well to copy. It also has decent performance, as you'd expect from a Kirkwood-based NAS. But it won't outshine more expensive Atom-based products.

Unfortunately, like the Cloudplug, it's also comparatively pricey for a dual-drive NAS at $371 without drives, but with a one year subscription for remote access and 10 GB of storage. Hassle factor is a bit higher, too, since there's no retail / etail availability. You have to email a CTERA "partner" for a quote and I don't know how long order fulfillment takes. Service will also be up to CTERA's "partners", too.

It's clear CTERA wants to concentrate on tending its cloud, not end-users. So if you end up deciding to take the plunge, ask lots of questions from whoever you order from and be sure you know who will be there for you when you need a helping hand.
