Title: Considering DIY NAS with 4-Bay DAS and Raspberry Pi - Worth It?

Body:

Hi everyone!

I've been exploring options for setting up a NAS at home and stumbled upon the idea of using a 4-bay DAS connected to a Raspberry Pi to create a DIY NAS. I'm drawn to this because of the potentially lower cost compared to buying a ready-made NAS unit. However, I'm curious about the performance and practicality of such a setup.

Here's what I'm considering:

DAS: A 4-bay Direct Attached Storage for the hard drives. Raspberry Pi: Using this as the 'brain' of the NAS. Purpose: Primarily for home use – storing media, personal files, and maybe some light server tasks. Budget: Trying to keep the costs lower than a pre-built NAS so I can focus in getting big quality HDDs

Is this a viable option?
