Newegg offers the Crucial M500 120GB Serial ATA 6Gb/s 2.5" Internal SSD, model no. CT120M500SSD1, for $59.99 with free shipping. (Amazon offers it for the same.) That's the lowest total price we could find by $15, although we saw it for $4 less last week. It features read speeds of up to 500MB/s and write speeds up to 130MB/s.
