From being about 15 until a few years ago I use to buy multiple DVDs every week (damn you HMV and Virgin 5 for £20!) Before my son was born we moved house and the room I made my office has this full length storage space running behind the wall so I decided instead of having shelves full of DVDs I will rip them to ISOs and put them in this storage space.

I bought 3 of these https://www.amazon.co.uk/Seagate-Expansion-Desktop-External-Drive/dp/B00UNA1O0W (the price has gone up!) put all the ISOs on them and connected them to a Raspberry pi running OpenElec, I then later got another Rapsberry pi for the bedroom so I can now watch my DVD collection upstairs or downstairs with all the extras, commentaries etc. The reason I ripped them to ISO is because I enjoy watching the making of's and extras.

I later got another 3 of those hard drives for backups. I don't tend to buy DVDs anymore, everything is on Bluray or Netflix but I do sometimes buy older films or TV shows not available elsewhere so I'm looking for more space.

So my question is 'is there a cheaper alternative to buying external hard drives, factoring in the cost of the hardware and the cost of running it?'

I've looked at NAS but unless I spend thousands I can't find any that have more than 2 or 3 bays then the cost of hard drives big enough to store my DVDs on 3 internal hard drives is a lot more than external, my current solution has lasted me 4 years so I'm looking for something with a lot of space, or the ability to upgrade it cheaply so I can run it for a few more years.

I think i'm probably better off with the external drive option then. I could buy 24 5TB external drives cheaper than that

If you're going to connect that many drives presumably over USB, I'd wonder what your performance is going to be like. I'd also wonder about the risk you pose to the data stored on each of these drives as no doubt they're mechanical spinning disks. If you're ok with re-ripping 5TB of video files, I guess it'll be ok for you. As much as it sucks, you're better off biting the bullet and buying an array type device that has some sort of RAID support. With the size of drives we're talking about here, anything short of RAID 6 would be unacceptable.

This is definitely a task for a multi-bay NAS that you can easily access from any and all devices at once in one central location, you can get a Synology DS416 4 bay NAS that supports up to 10TB drives for £328.49 or less: https://www.scan.co.uk/products/4-b...14ghz-dual-core-cpu-1gb-ddr3-ram-2x-gbe-3x-us

Then drop in 5TB to 10TB drives into it. If you want to survive a drive failure without data loss and without resorting to an external backup, setup RAID 5 but you'll lose the capacity of one full drive. Or just backup the important data to something or keep the original sources.

I strongly recommend against using RAID 5 on any array using 2TB or larger drives. The rebuild time during a failure puts the rest of the array at risk. It's been a best practice recommendation and what I have been telling all of my clients to go RAID 6 with 2TB or larger drives.

That's true I forgot about that, haven't used RAID 5 in years.
