Yesterday I replaced my FreeNAS with Windows Storage Server 2008. While FreeNAS is a great piece of software I finally realised it just wasn't for me, mainly because I am more comfortable within a Windows environment but there were some fairly big issues such as:
1. No JVM (You would have to install Diablo on FreeNAS if you wanted one and I like to stick with Sun's JVM). I do alot of Java development and really want to customise my Storage server with custom tools.
2. Bit Torrent client - Transmission is the default client and it seemed to prove a headache for many if wanting to update it. Most people just waited for the FreeNAS update which usually ships with the latest version. I wanted uTorrent back as it is by far the most lightweight, feature packed and fastest BT client I have ever used. Tranmission would only give me download speeds of around 3.5MBps but uTorrent is able to max my line at 6MBps.
Oh, and one more thing, I was quite surprised when I first booted Windows Storage Server 2008 to see that if was prompting me for credentials when I have never supplied any. The default password is "wSS2008!"
