Like in our previous reviews, we use Western Digital Caviar Black WD5001AAL drives and Intel NASPT 1.7.0 for our benchmarking. Besides RAID0 and RAID5, we will also check out the speed of a Synology Hybrid RAID built out of five disks and the performance of iSCSI volumes.
The first graph shows very good results. The DS1010+ is fast in every mode: the need for extra calculations for RAID5 doesn't affect the array's speed much. The peak read speed is almost as high as 100 MBps. The write speed is even higher. In fact, the numbers are higher than the theoretical bandwidth of the Gigabit Ethernet network, indicating that the benchmark is not designed for such speeds. We will have to look for other tools to use in our future reviews.
Compared to the top-end model of the last year, we can see a performance growth of about 50% at reading and up to 100% at writing, depending on the subtest and disk configuration. We must keep it in mind that the firmware version and even the file system have changed and affect the results, too.
The second group of tests was performed with four iSCSI volumes built on:
- A single disk in block access mode
- A single disk in file access mode
- Five disks in RAID0, in block mode
- Five disks in RAID0, in file mode
The iSCSI volume was connected to the PC using Windows’ standard tool and an NTFS partition was created on it.
We’ve got interesting results here. First, we can see that the peak speeds are generally comparable to classic disk arrays connected to the LAN via ordinary protocol. Second, we can see that the file-based iSCISI volume on a RAID0 array is better for multithreaded reading whereas the block access variants are better for writing.
So, the new top-end NAS from Synology delivers excellent performance in our tests, just as we could expect from it.
The arrival of the x86 platform to Synology’s NASes has been expected. It is rather odd that the company didn't make this step earlier. Perhaps the reason is that Synology could get such a high performance from its ARM and PPC platforms that they were competitive to x86-based NASes from other brands. The unique multifunctional firmware must have required more time for debugging, too. We must admit the adaptation is most successful. Nothing has changed for a user who accesses the DS1010+ via network as he is offered the same settings and functionality as with any other Synology NASes.
Talking about the interface, DSM 3.0 is significantly different from the previous versions. It is hard to definitely say if its multitasking interface is much of an advantage. After all, you don’t spend much time in the NAS’s interface. More importantly, Synology keeps on improving the internal services. Many of them, particularly File Station and Surveillance Station, have definitely become better.
Summing up this review, we can say that Synology has come up with yet another good product which raises the performance and functionality bar of top-end NASes a little bit higher again.
