Synology DS409slim NAS device
This Synology NAS device uses 2.5in drives, making it small and power efficient
- Small, simple Web interface, extensive RAID configuration options, decent file transfer speeds
- Limited total capacity compared to 3.5in NAS devices
Synology's first 2.5in network-attached storage offering has all the features of larger NAS devices in a smaller, power-efficient package. However, the cost and capacity limitations are major downsides.
Price$ 500.00 (AUD)
Synology's Disk Station DS409slim is one of the first network-attached storage (NAS) devices we've seen to make use of 2.5in notebook hard drives instead of 3.5 desktop hard drives. The use of 2.5in notebook drives allows the DS409slim to be smaller than most NAS devices on the market, and it will also consume less power. However, it also means that the maximum storage capacity of the DS409slim isn't as high as NAS devices that use 3.5in drives.
The Synology Disk Station DS409slim has four drive bays, yet retains a small stature that makes it look like a toy. It even comes with a display stand. Nevertheless, it has the same connectivity you would find on larger NAS devices, including eSATA, Gigabit Ethernet and two USB ports. You also get a one-touch copy button that can be used to easily make backups and from external drives.
The drives are hot-swappable and can be formatted in a number of configurations, including basic (separate drives), JBOD and RAID levels 0, 1, 1+0, 5, 5+Spare and 6.
You will be able to access the drive from computers running Windows, Mac OS X or Linux, and it can be set up as an FTP server, too.
Media features like UPnP, iTunes and photo servers are available, along with a download station from which you can queue BitTorrent, HTTP, FTP and eMule downloads. Unfortunately there is no way to schedule download times for these.
The Disk Station DS409slim's Disk Manager is similar to QNAP's revamped Firmware 3.0 Web interface. It uses an icon-based interface and configuration wizards, which will help people without much experience of network-attached storage.
Like QNAP's TS-219 Turbo NAS, Synology also allows you to expand the Disk Station DS409slim's functionality through third-party Linux packages, which can be installed through the Disk Manager interface. These packages are available to download from the Synology Web site and allow you to install Web site and network management software, for example.
The DS409slim NAS device has a 1.2GHz CPU and 128MB of RAM, and it produces respectable file transfer speeds. For our tests, we installed three solid-state drives — one Intel X25-M 32GB drive and two Solidata 32GB drives — in a RAID 0 configuration. The DS409slim was connected via Gigabit Ethernet to our test computer, which has a 300GB Western Digital VelociRaptor hard drive.
The NAS device performed strongly in the Intel NAS Performance Toolkit HD playback test, where it streamed 720p video at an average rate of 71.7 megabytes per second (MBps). It was also able to simultaneously play back and record high-definition footage at a rate of 59.6MBps.
In our own real world file transfer tests, the DS409slim wrote 20GB worth of 3-4GB files at a rate of 34.8MBps, read the same data at 57.6MBps, and performed a simultaneous read/write operation at a rate of 22.7MBps. It wrote 3GB worth of 1MB files at a rate of 23.3MBps, read them at 35.7MBps and performed a simultaneous read/write operation at 9.4MBps. These speeds are roughly on par with the similarly powerful two-bay QNAP TS-219 Turbo NAS.
Conventional 2.5in hard drives are quieter than 3.5in drives, and solid-state drives are completely silent. This makes the DS409slim the perfect NAS if you want something that won't make much noise. Power efficiency is also better than other NAS devices. During testing the Disk Station DS409slim (configured with three solid-state drives) consumed 11.5 Watts when idle, and a maximum of 14W when writing data to the drives. By comparison, the two-bay QNAP TS-219 Turbo NAS required 23W when running two 3.5in hard drives.
However, there are still some disadvantages to using 2.5in hard drives. They typically cost more than 3.5in drives at the same capacity — particularly when it comes to solid-state drives — and the DS409slim's total capacity is currently limited 2TB due to smaller individual drive capacities (the current maximum capacity of 2.5in drives is currently 500GB).

First impression on unpacking the Q702 test unit was the solid feel and clean, minimalist styling.
For work use, Microsoft Word and Excel programs pre-installed on the device are adequate for preparing short documents.
The Fujitsu LifeBook UH574 allowed for great mobility without being obnoxiously heavy or clunky. Its twelve hours of battery life did not disappoint.
The screen was particularly good. It is bright and visible from most angles, however heat is an issue, particularly around the Windows button on the front, and on the back where the battery housing is located.
My first impression after unboxing the Q702 is that it is a nice looking unit. Styling is somewhat minimalist but very effective. The tablet part, once detached, has a nice weight, and no buttons or switches are located in awkward or intrusive positions.
