Miscellaneous Factors and Final Words

The Synology RS10613xs+ is a 10-bay NAS, and there are many applicable disk configurations (JBOD / RAID-0 / RAID-1 / RAID-5 / RAID-6 / RAID-10). Most users looking for a balance between performance and redundancy are going to choose RAID-5. Hence, we performed all our expansion / rebuild duration testing as well as power consumption recording with the unit configured in RAID-5 mode. The disks used for benchmarking (OCZ Vector 120 GB) were also used in this section. The table below presents the average power consumption of the unit as well as time taken for various RAID-related activities.

RS10613xs+ RAID Expansion and Rebuild / Power Consumption
Activity Duration (HH:MM:SS) Power Consumption (Outlet 1 / W) Power Consumption (Outlet 2 / W) Total Power Consumption (W)
Diskless   52.9 67.4 120.3
Single Disk Initialization   46.5 61.61 108.11
RAID-0 to RAID-1 (116 GB to 116 GB / 1 to 2 Drives) 0:30:05 44.4 59.37 103.77
RAID-1 to RAID-5 (116 GB to 233 GB / 2 to 3 Drives) 0:37:53 49.82 65.91 115.73
RAID-5 Expansion (233 GB to 350 GB / 3 to 4 Drives) 00:24:10 54.42 70.98 125.4
RAID-5 Expansion (350 GB to 467 GB / 4 to 5 Drives) 00:21:40 57.61 74.29 131.9
RAID-5 Expansion (467 GB to 584 GB / 5 to 6 Drives) 00:21:10 61.1 78.29 139.39
RAID-5 Expansion (584 GB to 700 GB / 6 to 7 Drives) 00:21:10 63.77 81.23 145
RAID-5 Expansion (700 GB to 817 GB / 7 to 8 Drives) 00:20:41 66.8 85 151.8
RAID-5 Expansion (817 GB to 934 GB / 8 to 9 Drives) 00:22:41 67.92 86.16 154.08
RAID-5 Expansion (934 GB to 1051 GB / 9 to 10 Drives) 00:25:11 69.34 87.36 156.7
RAID-5 Rebuild (1168 GB to 1285 GB / 9 to 10 drives) 00:19:33 59.78 76.6 136.38

Unlike Atom-based units, RAID expansion and rebuild don't seem to take progressively longer as the number of disks increase.

Coming to the business end of the review, the Synology RS10613xs+ manages to tick all the right boxes in its market segment. Support for both SAS and SATA disks ensures compatibility with the requirements of a wide variety of SMBs and SMEs. We have not even covered some exciting SMB-targeted features in DSM such as Synology High Availability (which uses a dedicated second unit as a seamless failover replacement) and official support for multiple virtualization solutions including VMWare, Citrix and Hyper-V.

A couple of weeks back, Synology introduced the follow-up SATA-only RS3614xs+ with 12-bays and slots for up to two 10G NICs. Compared to the advertised 2000 MBps for the RS10613xs+, the RS3614xs+ can go up to 3200 MBps and 620K IOPS. Given Synology's commitment to the this lineup, SMBs looking for enterprise features in their storage server would do little wrong in going with Synology's xs+ series for the perfect mid-point between a NAS and a SAN.

    Raid5 is fine so long as you keep patrol reads enabled. All those horror stories about failed rebuilds come from people that don't know what patrol reads are for, and turned them off for some stupid reason or another, or were too cheap to buy a real raid controller.
