IT Pro Verdict
The DS209+ is an impressive NAS with a long list of generally well-implemented and useful features. However, since it doesn’t come fitted with any disks, we wish its price were lower. We’re also disappointed to see that the chassis is almost identical to Synology’s previous two disk NAS devices. A model with more easily accessible disks is long overdue. Nevertheless, the DS209+ is an excellent NAS that’s well worth buying if you can live with its few caveats.
NAS (Network Attached Storage) drives are increasingly popular at the moment, as they offer quick and easy centralised storage for businesses. We've been greatly impressed by previous Synology NAS devices, but they tend to be expensive, which can be a problem in these financially lean times. This is especially true since they don't come fitted with any hard disks you have to provide your own. The Disk Station DS209+ is relatively inexpensive at just over 300 ex. VAT, but it uses the same firmware and web management interface as Synology's more expensive models.
The DS209+ can take up to a pair of 3.5in SATA hard disks, but it doesn't use removable disk trays or have a tool-free accessible drive bay. To fit disks, you have to slide off the side panel, fix your disks into the metal holding bracket using the provided screws and connect the disks to the motherboard using the included SATA data and power cables. The process is a little fiddly, but it's not too difficult to accomplish. More easily accessible disks would help reduce down time when replacing disks and rebuilding a RAID array though.
Both RAID 0 and RAID 1 are supported. Even if you initially use the DS209+ with only one disk, you can still add a second to create a RAID 1 array without wiping the first disk. It's always a good idea to back up your data when performing such fundamental configuration tasks though.
We used three 10GB sets of files to test the copy speeds of the DS209+. Our set of large test files consisted of several 100MB WAV files totalling 10GB. Our set of medium test files consisted of 4MB JPEG images totalling 10GB, while our small files test consisted of several Word and system files each only a few KB in size, but totalling 10GB.
We were impressed with the file copying performance of the DS209+. When copying large and medium sized files, it approached the performance of a FireWire 800 hard disk. Its speed transferring small files wasn't quite as quick, but was still fast for a NAS. When configured as RAID 0, it wrote large files at 34.1MB/s and read them at 43.21MB/s. It wrote medium files at 33.85MB/s and read them at 34.44MB/s. Small files were written at 8.57MB/s and were read at 2.59MB/s.
Its performance wasn't significantly slower when configured as RAID 1, so you're not sacrificing speed for data redundancy if you choose it over RAID 0. Large files were written at 32.28MB/s and read at 38.25MB/s. Medium files were written at 30.56MB/s and read at 31.11MB/s, while small files were copied at 7.72MB/s and 2.55MB/s respectively.
Configuring the DS209+ is straightforward thanks to its web management interface. Since it's built using AJAX, it looks slicker and feels more responsive than other NAS web management interfaces we've seen. Creating new users is quick since the user account creation wizard also lets you assign them to existing user groups and grant or restrict their access privileges to existing shared folders. If you have lots of users on your network, then you'll appreciate the ability to create multiple user accounts with identical settings with only a few mouse clicks.
