I tested the DS213+ with DSM 4.1-2668 firmware, using our NAS test process with RAID 0 and 1 volumes.
Windows File Copy tests show writes slower than reads by 20 MB/s for RAID 0 and almost 30 MB/s for RAID 1. In both RAID 0 and 1, reads measured just shy of 100 MB/s.
Synology DS213+ DiskStation benchmark summary
Intel NASPT File Copy results were mixed, with 99 MB/s write for RAID 0 and only 84 MB/s for RAID 1. Read throughput was lower than measured with Windows Filecopy, coming in around 90 MB/s in both cases.
iSCSI performance of 62 MB/s for write and 65 MB/s for read is just about the same as we measured for the DS413.
Attached backup tests were run with our standard Startech USB 3.0 eSATA to SATA Hard Drive Docking Station (SATDOCKU3SEF) containing a WD Velociraptor WD3000HLFS 300 GB drive. Results using a USB 3.0 connection were again disappointing, with only minor gains over USB 2.0. Best throughput of just shy of 80 MB/s was again obtained using eSATA and a FAT-formatted drive.
Network backup to a DeltaCopy target on our NAS Testbed system measured around 33 MB/s, virtually the same as measured with the DS413.
Performance - Comparative
To put the DS213+' performance in perspective, I created a set of custom performance charts using the NAS Finder. Since there are no other current-generation two-bay Freescale-based NASes to compare, I chose two that run on 1.6 GHz Marvell Kirwood SoC's: ZyXEL's NSA325; and NETGEAR's ReadyNAS Duo v2. I also threw in an Intel D525 Atom powered Iomega's px2-300d to make things interesting.
The graph composite below shows Windows and NASPT RAID 1 file copy write and read results for the group. The Atom-powered Iomega tops the charts for Windows and NASPT writes. But the DS213+ takes top honors for reads in both benchmarks.
RAID 1 file copy performance comparison
The one thing consistent in the results is that the NETGEAR comes in at the bottom of the group almost every time. In all but the Windows File Copy RAID 1 Read benchmark, it lags the others products by at least 20 MB/s.
I didn't check encrypted performance, because I think I've shown in enough recent reviews that you can expect at least a 50% throughput reduction on large file copies to an encrypted volume. Since the DS213+ and DS413 share common hardware, I've copied in Table 2 from the DS413 review in case you'd like to see the hit that encryption imposes on other benchmarks.
|Win File Copy Write||70.19||22.2||-68|
|Win File Copy Read||95.75||42.63||-55|

Use the NAS Charts to further explore and compare the DS213+'s performance
Once again, the results show that Synology has made a crafty choice of CPU with the dual-core Freescale QorIQ P1022. But this time, the price gap between its pricing and an Atom-based equivalent isn't as wide as it was with the DS413. A diskless D525 Atom-based Iomega px2-300d can be currently had for as little at $428, while the DS213+ will run you $400.
If you don't care about all the extra functions that Synology crams into its NASes and are willing to sacrifice a bit of performance, the ZyXEL NSA325 at $170 can look mightly tasty.
