Seagate NAS 4-Bay with Marvell ARMADA 370 Review
by Ganesh T S on July 24, 2014 8:30 AM ESTMulti-Client Performance - CIFS on Windows
We put the Seagate NAS 4-bay through some IOMeter tests with a CIFS share being accessed from up to 25 VMs simultaneously. The following four graphs show the total available bandwidth and the average response time while being subject to different types of workloads through IOMeter. The tool also reports various other metrics of interest such as maximum response time, read and write IOPS, separate read and write bandwidth figures etc. Some of the interesting aspects from our IOMeter benchmarking run can be found here. Note that even though there are two network links, the CPU is too weak to support 802.3ad dynamic link aggregation. Instead, Seagate advises that the second port be used as a failover link.
Even though Seagate advises usage of this NAS model for workgroups of up to 25, we see performance starting to take a hit for certain workloads with just five clients in the mix. That said, units with similar pricing also exhibit the same behavior.

Didn't see thermals mentioned. Seagate goes for record-setting internal temps by totally sealing their drives in plastic. I have several GoFlex multi-TB units that, out of the box, exceed their max rated limits! It seems impossible that a company that can build a modern hard drive can't produce a ventilated plastic box to house it. At least I thought it was impossible, but technology advances....Yeah I know these are different animals but they still say "Seagate" on them, and those incompetent packaging engineers must have moved on to some other project. Could be this one.

and probably many other web comments by now.
BTW the fix on the GoFlex is to rip half the cover off, and hold the remaining half on with a rubber band. Looks real nice.

I was considering getting three or four of these to replace my somewhat flaky Unraid server, but Arbie's comment makes me worry that this will be drive-destroying junk.Ganesh, can you tell us about any thermal issues?

This design includes a 120mm fan. While measurements would be nice, I doubt this design has the same problem as the goflex enclosure.woggs - Thursday, July 24, 2014 - link
The pics on page 2 show the fan but no other vent holes for air flow. Where does the air from the fan go? Are there bottom vent holes we can't see?MichaelD - Thursday, July 24, 2014 - link
The fan pulls air through the chassis from front to back. The air enters through the spaces around the drive sleds and is pulled through/over the drives before being pushed out the perforated rear panel.I've been looking to get a NAS device to replace the W7 box/HW RAID card setup I have running at home as a NAS. I built that box 3 years ago to replace the SOHO NAS JUNK that was for sale at that time. I.E. under $600 or so.
This box looks promising...but still, the storage format is not compatible with Windows. If the NAS itself fails, I have to wait until a replacement NAS is purchased to see if my data is there, and that worries me.

Just saw that even though it's got two GbE ports, this device does not support Link Aggregation. A real shame. Not a deal-breaker for me but it's nit to pick.MadMan007 - Thursday, July 24, 2014 - link
It depends on the NAS drive file system actually. There are ext4 drivers for Windows that enable read/write of ext4 volumes. I have read that people are able to pull a drive from a RAID1 and read it on a Windows machine...perhaps it depends on the NAS vendor as well though.ganeshts - Thursday, July 24, 2014 - link
This unit's lineage is not related to the GoFlex, rather, it is from LaCie (the use of Noctua fans, for example).I am very happy with the thermal performance. All our evaluation was done with the WD Re drives (known for not being very 'cool'), and never once did the temperatures go above 50 C in our stress tests.

seriously, how can you keep flogging the crap ARMADA 370 SoC in a NAS as a good investment, tindustrial hey are far lower spec than even a A8 in data throughput and the ports are second rate add-on's for a soc that cant cope.....even an old 5.4" single board computer with a cheap case would be far more forgiving of data throughput, http://www.abigo4u.com/review/product/list/id/2136...
LS-576TXD 5.25" Embedded board with Intel QM77 w/6 x Giga LAN
or one of the newer 3.5" smb's would give far better return on investmant, just bung freenas on there and be far better supported.

Dude, just accept that different people have different desires and needs.Personally I don't see the point of these NAS boxes --- I can (and do) create much the same thing by hooking up a bunch of external drives to an old Mac and using OSX's soft RAID. Meets my needs, may not meet yours, especially if your needs demand RAID5 or live disk replacement.
Likewise some other people's NEEDs (not desires, NEEDs) are "absolutely trivial installation", or "comes in a single box that can easily be moved, with no bits hanging out".
You're like the salesman who, asked "please show me the laptops department" starts ranting about "you don't want a laptop, you want a tablet. Here, let me show you our fine selection of tablets."
