Sweet spot of size & speed for an SSD

Not the fastest SSD out there but the speed is limited to the type of data port the drive it plugged into. (SATA) I was upgrading from a 256GB SSD because I kept running out of room with wanting to keep all my software on the SSD. I do have a 2nd hard drive for data but is nowhere as fast as this drive. Overall enjoying the extra room and faster speeds than my last SSD. If you are looking for something really fast you need to get a PCI-E SSD but those are big $$$.
