Fry's Electronics offers the SanDisk 120GB Plus Internal SATA 6Gb/s SSD, model no. SDSSDA-120G-G25, for $49 with free shipping. That's $7 below our April mention and the lowest total price we've seen. (Outside of the price below, it's a current low by $1, although most charge $55 or more.) It features read speeds of up to 520MB/s and write speeds of up to 180MB/s.

Of note, Amazon has it for same price, but it won't ship for two to four weeks.
