I got a HP microserver on cashback for effectively £110 a while back but never got round to setting it up yet. Finally ordered 4x3TB hard disks for it, primarily to backup the master copy of files on my main desktop. That is currently mirrored internally, which I can then split to free up space there. It has 4 drive bays so to not waste space on OS install I was going to use FreeNAS or similar on USB stick.
Also ordered Windows home server too, but that’ll go on what was my desktop two generations ago which I’ll resurrect. That can hold my older <=1TB hard disks to ease transfer of archived data back to a live system.
Made me wonder if I should put the 4x3TB disks in the windows system and the small disks in the microserver instead… too many choices! All the hard disk tools I’m familiar with (for monitoring and checking) are windows based.
