Performance - Summaries
6.0.8 firmware was used with our standard NAS test process for testing. As noted earlier, all testing was done on the RN31441E sample. The published RN314 benchmarks used four drives configured in single RAID 0, 5 and 10 volumes. The RN312 tests used two drives in single RAID 0 and 1 volumes. The RN316 data is just a copy of the RN314, since our practice is to test NASes with greater than four bays with only four drives.
Volume rebuild and sync times definitely benefitted from the Atom CPU vs. the Marvell in the RN100's. It took only 3h 24m to build and completely sync a 4 x 1 TB RAID 5 volume and 3h 18m for the same disks configured in RAID 10. The same rebuild / sync times on the RN104 came in at 31h 30m and 18h 30m for RAID 5 and 10, respectively!
Since we have the NAS Ranker, I'll make only a few observations about each benchmark summary. The RN312's below shows equal Windows File Copy read and write performance for both RAID 0 and 1 volumes measuring about 100 MB/s. NASPT file copy performance was also essentially the same between write and read, with writes up at 119 MB/s and reads dropping to the mid-80 MB/s range.
NETGEAR RN312 Benchmark Summary
Results for the RN314 were again close to 100 MB/s, but showed about 10 MB/s lower throughput for RAID 5 vs. RAID 0 for both Windows file copy and NASPT file copy writes. RAID 10 writes, on the other hand, were about the same as RAID 0 for both benchmark types. Windows file copy writes and reads all were between 91 and 100 MB/s. NASPT file copy writes ranged from 111 to 118 MB/s and reads all stayed in the mid 80 MB/s range.

Performance - Ranking
The RN300's are all classed as Atom-2 in the NAS Ranker (dual-core Intel Atom), which is its default view. We need to go to the second page of results before we find the first RN300—the RN312—in the #13 total rank. But among two-bay NASes in this class, the RN312 ranks #3, behind the Iomega px2-300d and QNAP TS-269 Pro.
The Ranker Performance Summary for the RN312 shows higher ranking for RAID 1 vs. RAID 0, a desirable attribute for a RAID 1 device. Looking at the NAS Chart Windows File Copy RAID 1 results for all two-bay devices in this class, the RN312 leads the next-best QNAP TS-269 Pro by 100 MB/s vs. 85 MB/s. The margin for NASPT File Copy write isn't as much, only 5 MB/s.
Those are about the RN312's only strong points, except for a #5 rank for Video Playback and #9 for rsync backup. Attached backup throughput is particularly poor for a product in this class. For an NTFS-formatted drive connected via USB 3.0, the Marvell-powered (SoC-1 class) QNAP TS-220 and TS-221 spank the RN312 soundly with 36 and 48 MB/s backups vs. the RN312's anemic 17 MB/s.
