I have a Dell Precision T5500 with 2 Dual Xeon Quad Core processors @ 2.4GHz and 24 Gb ECC RAM. I am maxed out on Disk space as i just have 2 256 GB Seagate SATA 7200 RPM drives. I would like to get a hard drive with more capacity for running multiple VMs. Would appreciate some suggestions on a good internal drive (1 TB or 2TB?).
