1GB Single-Disk Test Results
The bottom line for any storage device is the combination of capacity and transfer speed. For a network attached storage server, the differences are all about the infrastructure that is placed around the basic HDD array. Since capacity is something that's easy to define and measure, the real question for any NAS product is how fast will it Read and Write data. For this reason, Benchmark Reviews primarily measures NAS performance as the bandwidth achieved during a file transfer test. The first tests we perform utilize a single 1GB (1000 megabytes / 1,000,000,000 bytes) file in a transfer to and from the NAS.
With all the NAS units operating in single-disk mode, there are three leaders at the top of the chart, the EonNAS 850X, the QNAP TS-879U-RP, and the Thecus N5550. The differences are mostly down to CPU performance in this test, although some of the other infrastructure ICs do have an impact. The EonNAS Pro 850X is doing very well in this test, considering the ZFS file system extracts a performance penalty for the extra features it provides. The extra memory helps counteract that, and allows the 850X to hang in there at the top of the heap with its Linux cousins. With a top transfer rate of 99.8 MB/s, it's also well above the rest of the pack, which is running with less powerful CPUs. Most devices performed better on the 1GB Read test with Jumbo Frames enabled, but the EonNAS 850X and the QNAP TS-879U-RP did not. Most people who buy an 8-bay NAS don't care too much about single disk performance, but it's useful to get an understanding of any possible issues with the basic architecture of the system. The EonNAS Pro 850X architecture doesn't claim the top spot in Read performance, but let's look at Write performance now.
Moving on to the 1 GB write bandwidth test, the EonNAS Pro 850X makes a leap in performance, with an average Write speed of 114.3 MB/s putting it in a three-way tie for first place with the TS-879U-RP and the N5550. The Write test also evened out the Jumbo Frame performance differences on the 850X, by achieving almost identical results with MTU values of 1500 and 8192. Some of the other units had trouble in this test with the standard MTU setting, and it probably hurt the ReadyNAS NV+ v2 performance, too. For the most part, the Write results are in three groupings, with units based on the: Intel i3, Intel Atom, and Marvell CPUs.
Next up is 10 GB (1000 metric megabytes / 10,000,000,000 bytes) file transfer testing. Using the single-disk configuration in each NAS, and a Gigabit Ethernet connection, network throughput will be put to the test, and the effect of any system or hardware caches will be minimized.
10GB Single-Disk Test Results
Examining 10GB basic file transfer speeds, the mid-range QNAP models all got a boost, compared to the 1 GB file transfers. Their read speed went up by approximately 10 MB/s, to a combined average of 95 MB/s. The EonNAS 850X didn't pick up any performance gains when reading the larger file, nor did the QNAP TS-879U-RP, but the Thecus N5550 gained a few points. Clearly none of these units were bothered by handling very large files, but some also got an unexpected boost. Later in our testing, we will look at some other NAS test protocols that feature small file sizes, which is a more common situation for both front-line and back-line storage applications. Once again, you get none of the advantages of redundancy with a single disk or JBOD configuration, and most NAS users will go for one of the RAID configurations. These figures are not exactly what the average user will experience; those will be seen later in our RAID 5 tests.
In our 10GB write performance tests, the performance of all the NAS units is similar to their showing with the smaller sized, 1 GB file. The EonNAS Pro 850X hits a slightly higher performance level, at 114.4/115.4 MB/s, with 1500 and 9000 MTU values. Like the results with 1GB files, the top three NAS devices are in a virtual 3-way tie here. The Intel Atom and Marvell-based units all fall way back on this test.
Next we're going to look at RAID 5 performance, where the EonNAS will have to compete with some heavy-duty challengers from QNAP and Thecus. Since the QNAP TS-259 Pro and TS-219P+ don't support the RAID5 configuration that we normally use to test large format NAS products, we won't be including their results in this next comparison.
