Earlier this year we tested Network Attached Storage (NAS) appliances. Now we're reviewing software-based NAS that you can load onto your own equipment — whether it's a PC, server, virtual machine, or in the cloud.
We looked at FreeNAS, Openfiler, Open-E DSS, NexentaStor, and SoftNAS. All offer some sort of free solution or service, with some being fully open sourced.
