Hi, thanks in advance for any help. I have no idea if it's even possible to do what I want. I have an HP xw4600 workstation. It's built like a battleship and I'd like to keep it. I currently have a 1tb boot drive and a 4tb storage drive. I'd like to add two more drives. There are only two slots which are both full but there's enough room in the case to fit two more drives. There are two SATA sockets on what is the motherboard (?) but none of the other plug that goes into the hard drive. Both of them are linked together and lead to the power supply. If it's possible for me to fit two new drives it would be much preferable to having to fund a new desktop. I'd also like to swap out the current boot drive for a new one. I wouldn't mind a solid state drive if that were possible. Any help or advice would be greatly appreciated.
