Adding more drives Dell Precision T5820

Hello,

depending on the kind ( size ) of drive/s you want to use, Icy Dock adapters could be a solution to get more storage space out of the 5.25" bay

I mean outside the 5 bays is there any way to fit those ssd's for example so I can fit 5 3.5 hdd in the bays.

Well, you could repurpose the slim cd/dvd bay, if you want to mount properly the ssd. Otherwise I think you can only be creative with the internal space on the very bottom on the cards area

You can add one or more PCIe NVMe adaptors (that can take from 1 to 4 NVMe drives) and it will be a lot faster than SSDs

e.g. In the UK, you can get an adaptor for a single NVMe drive (needs an x4 slot) for under £20, the dual NVMe (x8 slot) and quad NVMe (x16 slot) Dell Ultraspeed adaptors tend to be around £45 and £75 respectively on eBay.

Then it's just a matter of your preference in drives, personally I like the Crucial T500 series (currently £77 (1TB) / £127 (2TB) / £246 (4TB) on Amazon UK)
