Synology's DiskStation DS214 was the dear winner in our last NAS Labs test, but the best things in life are never free, and the downside of this two-bay NAS was its sligntly high price. However, you can still join the Synolcgy NAS party without paying over the odds, as the company's new single-bay DS115J costs a more palatable £81 inc VAT.
As it only accommodates a single hard disk, RAID isn't even on the table. Although this means you might lose some performance, or the option of data mirroring, it makes the device much simplerto set up and use. You just plug in a drive turn it on, install the DiskStation Marager software and it's ready to go. There's no chance of waking up one day to find a drive dropped from the array, and there's none of the increased risk of mechanical failure of RAID 0 either.
