Not really a viable solution for me as I need 10tb of space. I can't even buy a 10tb ssd. An 8tb ssd is £600 roughly, vs a 10tb hdd which is roughly £200. I have a small ssd for the OS and I'm happy with that being loose in the case where the optical drive usually sits, but I don't want the hdd sat there loose due to the extra wear that it'd get because of the moving parts. 

It would be better to install a 2.5inch SSD instead.

If you want to use an old-school spinning-platter HDD with a SFF, this is a better solution. HDD is so slow, there is really no speed bottleneck.

Thanks, I'll give that a go and let you know how I get on

1. You put the 10tb HDD in the external USB-3.0 Enclosure. I suggest you get TWO and use one for a backup, because when it crashes, that's a lot of data to lose all at once.

Or, just go ahead and invest in a Synology NAS. With a 4-bay, you can setup a RAID-5 Redundant array.

2. I suggest you mount any-and-all internal drives securely. 

• Thanks, a 3420 caddy from ebay worked perfectly in my 3430  

Happy to hear

@GoldieLocks89​ Hello... Just wondering if 10tb 3.5" Sata Hdd worked for you? I have Precision 3430 Sff currently with 2tb 3.5" Wd Red Drive and I am looking to replace it with 8tb 3.5" WD Red (just for storage and not for boot/os). The specs of this machine says that it only supports up to 4tb Sata Hdd.
