EonNAS Pro 850X Conclusion

Non-Traditional NAS Test Results

In addition to measuring simple timed transfers, to determine how fast it will read and write contiguous blocks of data, Benchmark Reviews also measures NAS performance using some tests that are traditionally used for internal drives. By mapping the EonNAS Pro 850X as a local drive, some of our favorite HDD/SSD benchmarking tools worked just fine. Just like the NASPT test suite, I only run these tests on the RAID 5 configuration, as that is the most realistic scenario for a system like this. Some NAS products don't work too well with this type of test program; even though they may have the ability to map the NAS device to a drive letter, they're still not treated like local drives by the Operating System. I didn't have that problem with the EonNAS unit, so let's look at some results...

ATTO Disk Benchmark Results

The ATTO Disk Benchmark program is free, and offers a comprehensive set of test variables to work with. In terms of disk performance, it measures interface transfer rates at various intervals for a user-specified length and then reports read and write speeds for these spot-tests. There are some minor improvements made to the 2.46 version of the program that allow for test lengths up to 2GB, but all of our benchmarks are conducted with 256MB total length. ATTO Disk Benchmark requires that an active partition be set on the drive being tested. Please consider the results displayed by this benchmark to be basic bandwidth speed performance indicators.


The EonNAS Pro 850X turned in an excellent performance on ATTO, reaching a peak Read speed of 117.5 MB/s and a peak Write speed of 118.5 MB/s. These results are at the very top tier of NAS performance, and are bumping hard against the 125MB/s theoretical max transfer rate of Gigabit Ethernet. It's good to keep in mind that these ATTO tests are not always indicative of real-world performance, due to the sequential access mode used. In most cases, the results are going to be close to the numbers achieved in the timed Read and Write tests. They are also going to be way above the results from some of the more challenging tests in the Intel NASPT suite. It's interesting to note that the maximum performance level was already reached by the 32 kB block size test. That's a sign of good RAID management, and the high performance hard drives that are used in our testing.


CrystalDiskMark Results

CrystalDiskMark 3.0 is a file transfer and operational bandwidth benchmark tool from Crystal Dew World that offers performance transfer speed results using sequential, 512KB random, and 4KB random samples. For our test results chart below, the 4KB 32-Queue Depth read and write performance was measured using a 1000MB space. CrystalDiskMark requires that an active partition be set on the drive being tested. Benchmark Reviews uses CrystalDiskMark to illustrate operational IOPS performance with multiple threads. In addition to our other tests, this benchmark allows us to determine operational bandwidth under heavy load.


The combination of the EonNAS Pro 850X and four Western Digital Caviar Black WD7502AAEX 7200 RPM 64MB Cache SATA 6.0Gb/s generates some decent numbers in this test. It pulls a class-leading 73.9 MB/s on sequential Read and a competitive result of 97.4 MB/s average on sequential Write tests. The 4k tests show low numbers, but that's typical of HDDs, even in a RAID configuration. That's one of the huge advantages that SSDs bring to the table, is the ability to handle thousand of small data chunks very gracefully. But look at what happens when the Queue Depth is increased; the 4K:QD32 test is usually a killer for most storage systems, but the EonNAS scores a huge 114.4 MB/s on Read, while Write is still down in the single digits at 6.8 MB/s.


All in all, these are a respectable set of results for Network Attached Storage. Sure, they may be lower than a true local drive connection, with a high performance HDD connected directly into the SATA controller on the motherboard. But, for a NAS device mimicking a local HDD, the EonNAS Pro 850X performs quite well. None of the NAS devices we've tested are substantially faster, and none of them offers the security and space saving features you get with the ZFS file system on the EonNAS series.

    On the first page of the review you refer to an "Intel Atom Core i3 CPU". I think the word "Atom" needs to be removed...

    There is NO WAY an Atom CPU came anywhere near this product!
    Thanks, David.

    Is this product available from anywhere for purchase? It's an awesome box which is actually exactly what I've been looking for the last 4 years.

    There are several specialty vendors in the US that have a very deep product line in storage hardware. Here are two that have the 850X:

    Freenas and Nas4Free uses ZFS. My thoughts on this configuration are:

    1. Why no ECC memory?
    2. Why RAID when you can use zpools?

    I can't speak for Infortrend, but here's my opinion.

    1. Even though the 850X is a high performance model, it's still not in the same class as the EonNAS 3000 and EonNAS 5000 series, which DO have ECC memory as standard equipment.

    2. The underlying technology may be using VDev and zpool; I don't know. I'm not a Solaris tyro, so I can't log in to the OS and see that deeply into the machine. The application SW does use the terms "volume" and "pool" in the disk configuration commands, but RAID is mentioned as well.
