Overall the XN5004T offers quite a bit of flexibility and performance in a small NAS. There's only a single SSD slot but QSAN makes the most of it, enabling dedupe, compression and caching, which is a nice inclusion for a 4-bay NAS. Further, the PCIe expansion slot enabled more use-case specific options like 10GbE.
QSAN XCubeNAS XN5004T NAS Review
We've seen a lot of road maps, but none lately for end user HDDs. I really think WD/Seagate have conceded 2.5" SATA to SSDs. I'm figured out a path to live on a tiny SSD and NAS/cloud services. I prefer this actually in case of an SSD failure.
I really wonder how many of these SDS solutions can find a path to viability. Lenovo is partnered with like a dozen software partners and Dell is almost the same. Doesn't even count guys like this who have largely partnered with the white box guys. I guess Micron never figured out how to make Excelero work as a product. Probably a good thing, selling arrays isn't their jam.
Yeah, sorry that's ours. Unfortunately the little bugger has been extraordinarily effective at getting newsletter subs while all other methods have lagged exponentially. I'll see if we can fongufre some reprieve for those who have seen it recently or for those who have subscribed. I don't get it for some reason, I presumed it was because I closed the box once. Will investigate further.
We could remove VROC and run with software RAID and compare results, which of course we did not do for this review. There is a little overhead for VROC but it's not severe from what we can tell. Maybe some day we can dive into this further.
