I was thinking of buying a nas from maybe £100-150 and i was wondering what would be the best one? I've been looking around and I've found this one http://www.amazon.co.uk/Buffalo-LinkStation-MultiMedia-... but I'm not sure about it. It doesn't mention it's wireless so do i need a wireless router connected to it? To be honest i don't know a lot about Nas so i thought I'd ask you guys
I'm not specifically familiar with that one. I go by Newegg reviews since that community seems to be have fairly good self control. Also you can tell if a review is written by someone who bought the device or not.
You have to be VERY careful shopping for NAS boxes. The manufacturers tend to try to do a lot with very little. The only advantage of a NAS device like that vs. just having a computer do the job, is the NAS device will draw less power from the wall. Inside those NAS boxes is a little tiny computer, and the tendency is towards very low-end CPU and RAM. Sometimes each individual NAS task works fine, but trying more than two at once crashes or bogs it down.
It seems like I usually see a better spread of reviews for the single and dual-drive NAS boxes than the four or five drive boxes. I think the smaller units have more processor left for disk access and server activities because they aren't thinking as much about processing RAID storage.
I would recommend a two-drive unit running Raid-1. Disk failures are unfortunately getting much more common as manufacturers compete for the biggest TB award. Densities are going up, tolerances are going down, and methods aren't changing. With Raid-1, if a drive starts dying you just get a nice little blinking light and your data is fine.
