Frequently Asked Questions (FAQs)

1. Can I run a 4 bay NAS with 2 drives?

There are good news for you. The most popular NAS manufacturers like Qnap and Synology do allow you to build your NAS with just a 1 or 2 drives. Once you start running out of storage space you can add another drive and change setup from RAID1 to RAID5.

2. How many NAS bays do I need?

Buying Options A two-bay NAS is the best option for most people who want to use theirs for home backup, but if you need a more professional setup with additional file protection for your business records or you're going to be actively working on files stored on the NAS, get the four-bay QNAP TS-451D2-4G.

3. Can you mix drive sizes in a NAS?

If you dont want any redundancy (and the os allows it) you could put disks of different sizes in and concatenate the storage. If you want to use mirror the disks (raid 1) then you can probably use different size disks but you will only get the total capacity of the smallest disk.
