Am i cooked? SAS or SATA (lemmy.zip)

Very new to self hosting and truenas.

Got an old dell with 6x4tb of storage. Turns out they are all SAS drives and turns out hardware raid is the old thing now. Knowing none of this before what can I do with SAS drives connecting to my raid card (in photo) knowing that this is just a home NAS, SAS drives are more expensive and better to just go SATA.

What do you think?

Get a pcie to data, sell all the SAS drives and save up for 6x4tb of Seagate data drives?

What would you do with a dell server with old SAS drives if the end goal was a dependable home NAS for important home files?

I'm new to this so any input helps, thanks!

Get a SAS card that is in IT mode, use the SAS cables until your drives die, then buy SAS to SATA cables. Problem solved.

The SAS cables go in pairs of 4....

If one dies I have to replace 4... And the raid HDD builder won't be able to build more that 1 at a time probably?

Unless you were suggesting something else

With a SAS card in IT mode it will show up in your OS as 4 different drives. You can mix and match them however you like. You aren't restricted into pairs of 4. In fact one SAS cable can be multiplexed into many more than 4 drives.

LSI cards are generally easy to switch to IT mode. You should be able to find a guide on servethehome.com for your model.

This, but if you already have a SAS card in RAID mode you might be able to flash IT (AKA HBA) mode firmware instead of buying a new card.

Also, SAS cables fit SATA drives, but not vice versa. So no need to buy new cables.
