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.

In at least 2 of the links it is stated that when a RAID 5 rebuild is in process and a URE is encountered, all data is lost.I'm not sure what crap hardware that author has been using. When a URE is encountered during a rebuild the rebuild halts and you're back where you started - with a degraded array.
Now I'm not saying "RAID 5 is the BEST!" but the "facts" presented are false.
FYI I've rebuilt several hundred RAID 5 arrays over the last 15 years and have experienced a URE during rebuild exactly 2 times. You can cut down on UREs by performing a scheduled "Patrol Read" or functional equivalent. There is no way to know if the data is readable unless you read it. You can have a (fictional) "SUPER DUPER RAID 3000" with a ridiculous amount of redundancy but it's still theoretically possible to lose your data due to URE unless it's read and verified.

How do you feel about drives like the Western Digital Re which has a URE spec of 10^15 compared to other drives with a URE spec of 10^14 in RAID 5?802.11at - Friday, December 27, 2013 - link
Given the choice, I'll take RAID 10 all day in my enterprise environment.802.11at - Friday, December 27, 2013 - link
But FWIW, our HP LeftHand SAN is comprised of 6 nodes with 8 HDDs each in RAID 5 with the volumes actually running on a networked RAID 10.theangryintern - Monday, December 30, 2013 - link

The second link is quite wrong in the premises. It says that filesystems are really reliable today, well, they are not. There are lot of research showing how all filesystems are flawed today (except ZFS) with respect to data corruption protection. Only ZFS protects the data against data corruption. Read the research papers you will find here:http://en.wikipedia.org/wiki/ZFS#Data_integrity

How much are consumer grade (if any exist) 10 GbE NAS's, switches and PCIe cards?bobbozzo - Thursday, December 26, 2013 - link
$3000 for a 6-bay Netgear w 10gigEhttp://www.anandtech.com/show/7523/netgear-launche...

I don't think there are any 'consumer' 10gb switches yet.Master_shake_ - Saturday, December 28, 2013 - link
