Samsung offers a 2.5” 8.0 TB SSD if you want massive! Just keep in mind your system sadly can’t handle most drives as your system only has a SATA II (3.0 Gb/s) SATA port. So the drives you get need to be able to run at SATA II (3.0 Gb/s) not SATA III (6.0 Gb/s). There are only a few drives that still support SATA II. Sadly the 2.5” Seagate BarraCuda 4 TB HDD does not support running at SATA II its a fixed SATA III drive ;-{ You best bet is just going with a Samsung 860 EVO SSD or Samsung 870 QVO SSD These Samsung SSD’s are much better for a laptop than a HDD and unlike the Seagate drive which is fixed at SATA III speed the Samsung drives are auto sense! So they will match your systems I/O ports speed. You really should stick with the one drive, leave the optical drive alone.
