Thanks for sharing. I'm just wondering what is the maximum number
of hard disk a motherboard can support, i mean desktop motherboards.
And is it easy to attach a storage unit in case you want more space?
This company i'm talking about is growing with 1 Tb per year. I have talked
to them to archive the data but it's out of discusion because they almost
always need random parts of old projects and they want to access it ASAP.
a great day,
