Synology has done quite a decent job with the DS1517+. Of course, it's the first of what will be many 10Gbe solutions to make their way through the lab, so we aren't quite sure where it stands on this vacant landscape. I do have a few units on the way from other vendors, so that will surely be put to the test in the coming weeks, but for now, I can say the Synology showed a solid start for our 10Gbe testing.
Build quality is always rather solid for Synology units; we do get some on the lower-end that has thinner plastics or custom designed enclosures. With these larger bay units, the enclosure is mostly reused year after year, so there isn't much to change other than a quick swap of the rear I/O. With the DS1517+, the drive bays still click shut with ease, the locks turn without issue and it's a relatively noise free unit with two 80mm fans spinning efficiently.
The performance was interesting to see. NASPT wasn't very friendly as far as workloads are concerned but again NASPT has been around for quite a while and not very likely to be optimized for 10Gbe testing. Sequential performance confirmed we were receiving full 10Gbe throughput reaching 1200 MB/s in RAID 0 while RAID 5 topped 700 MB/s and RAID 6 700 MB/s as well.
Workload testing showed this unit to perform exceptionally well with Web Server, with each RAID array scaling almost perfectly as QD increased. Database topped 16,000 IOPS with File, Email, and Web Server all getting very close to 20,000 IOPS. Peak performance was found with Workstation reaching 23,000 IOPS QD128 in RAID 0.
These NAS systems are evolving every day, as new platforms emerge from Intel and others, it's easy to see it won't be long before 10Gbe is the norm. As I write this, I have the Annapurna Labs-powered DS1817 on the test bench with preliminary results showing some pretty strong numbers for a value-based eight-bay appliance.
It will be interesting to see how the Synology appliances stack up against the competition in the weeks and months to come.

The Bottom Line: Synology's DS1517+ is a solid entry into the high-performance, five-bay NAS segment. Adding in a 10GBe NIC can dramatically increase that performance and this NAS is ready for it.
