Seagate NAS 4-Bay with Marvell ARMADA 370 Review
by Ganesh T S on July 24, 2014 8:30 AM ESTSingle Client Performance - iSCSI on Windows
We created a 250 GB iSCSI target and mapped it on to a Windows VM in our testbed. The same NASPT benchmarks were run and the results are presented below. The observations we had in the CIFS section hold true here too. Some of the numbers are quite low compared to the competition, which means that there is scope for firmware improvement to ensure good performance with iSCSI.

Whoa, you mean a motherboard that costs more than this entire NAS performs better? SHOCKING!JeffFlanagan - Thursday, July 24, 2014 - link
Thanks Ganesh and others who commented on the cooling.harshw - Thursday, July 24, 2014 - link
Ganesh, I can attest to the fact that LaCie's fan design on their 5Big boxes for example - isn't really good for thermals. Like I commented earlier, I had a LaCie 5Big NAS Pro consistently overheat here in California where the ambient room temps can easily rise to 80F. I replaced the 120mm Noctua with a 150mm Thermaltake and also cut out the fan grill. It worked but the LaCie RAID config was already broken and no amount of recovery would help.ganeshts - Thursday, July 24, 2014 - link
That is disappointing to hear. I have the 5big Pro running without issues, but I have it perched on a shelf open on all four sides (basically a garage rack converted to hold stuff) where there is plenty of air-flow. One issue with the 5big box is that you have to make sure the underside is pretty clear (air intake is through that).That said, I do have more confidence in the NAS 4-bay, as the air is being pulled in through the front side of the unit. But, then, again, the NAS 4-bay doesn't have a metal body, so some heat loss through conduction will be missed.

With these huge RAID-Rebuild times greatly increasing the risk of a second drive failure, wouldn't it make sense to add a dedicated chip that speeds this up? This would even help during normal operation?Zan Lynx - Friday, July 25, 2014 - link
As far as I know, no current hardware is limited by the CPU when doing RAID rebuild. It is always the amount of time that it takes to read and write so many terabytes of data.Now maybe if the drive bays were fitted with SSDs it would be a problem.

From looking at recent tests and from my own kit at home it really looks like you need around 500MHz of ARM CPU power per 20-22MBps of data pumped down the cable.Zan Lynx - Friday, July 25, 2014 - link
Maybe the NAS builders should start using AMD Bobcat. My little home server built on a E-350 can fill a gigabit Ethernet link.wintermute000 - Sunday, July 27, 2014 - link
I agree. heck even Bill us the cost difference, what 50 more or whatever for a real cpu like a celeron
