I have recently been looking at the Samsung 850 EVO 500GB SSD. I have a SATA2 motherboard but the SSD is SATA3. I know it is compatible because my HDD is SATA3, but is it worth it? My current results from CrystalDiskMark4 say that my read speed is 113.6 MB/s and my write speed is 110.2 MB/s. Should I buy it or should I buy a new motherboard first?
