Buffalo TeraStation 3400D review

Price when reviewed

Buffalo’s TeraStation 3000 Series is aimed at SoHos and small businesses that want a simple, affordable NAS and IP SAN solution. There are two in the range: a rack-mount 4-bay model and this desktop version.

It’s offered in 4, 8, 12 and 16TB versions (there’s no diskless option). They’re all good value, with costs reduced by using a basic dual-core 1.3GHz Marvell Armada CPU and 1GB of RAM.

Stack the 3400D up against rivals from Qnap, Synology and Netgear, however, and it comes up short on features. All standard file-sharing protocols are supported, but remote cloud access is more basic, snapshots aren’t supported, and there’s no package service, so there are no extra utilities such as Dropbox to install.

Backup features are good. The price includes a ten-user copy of NovaBackup Business Essentials for scheduled workstation backup. There’s rsync replication to other TeraStations, and you can back up local data to external USB devices. You can also create scheduled jobs for copying data from local shares to others that have the Backup option enabled.

Along with Time Machine, the 3400D supports Amazon S3. We tested with our Amazon Web Services account, but found it only syncs the contents of a single share to one S3 bucket, and can’t run scheduled backup tasks to multiple buckets.

Performance is a mixed bag, with drag-and-drop copies of a 2.52GB video clip over Gigabit returning disparate read and write speeds of 103MB/sec and 60MB/sec. The latter hits backup performance hard. Our 22.4GB folder with 10,500 small files copied to a share at an average of only 38MB/sec; the Synology DS1513+ recorded 72MB/sec.

Where Buffalo undoubtedly wins is value, with the 8TB model undercutting its diskless Synology rival by around £40. It also beats Seagate’s cheap Business Storage 4-Bay NAS for performance. Before you buy, however, make sure you won’t miss any of the features that have been sacrificed to hit this price.
