I need to buy a pair of 2.5" disks for the root partition of a file server. These disks would essentially only contain the OS, so there will be practically no writing on them. Therefore, no SSD wear out should be an issue and the only thing I need is for the drive to keep responding to read requests.
In this setting, from what should I expect more reliability, an SSD or a HDD? I've heard of SSDs going bad because of the controller getting fried. Where should I put my money? Should I be looking at a pair of 2.5" HDDs or a pair of e.g. 60GB Intel SSDs?
