Missing piece of knowledge

[jbmorrisonjr@gmail.com]

Hi.

I'm looking into replacing 4 shared server drives (F:, G:, H:, I: ) with a NAS. The combined space is currently 18TB. we are expanding at the rate of about 5TB per year.

My question is, do I need a NAS "unit" per drive or can one be configured to present the 4 drives? I understand that there are performance and backup considerations and a lot of "YMMV" issues.

I'm just looking for a solution that allows me to just add more HDD's when needed and allocate the space as appropriate.

Thanks

You can create folders on any NAS, which can then be mapped as drives.

The "add more HDDs when needed" part of your requirement can be tricky. There are different approaches such as:
Drobo
Windows Storage Spaces (available in Windows Server 2012 and Win 8)
NETGEAR xRAID
Synology Hybrid RAID
