MacMall offers the Samsung 250GB 840 Series Serial ATA 6Gb/s 2.5" Internal SSD, model no. MZ-7TD250BW, for $149.99 with free shipping ($0.60/GB). (B&H Photo Video and eCost offer it for the same price.) That's $4 under our mention from two weeks ago and the lowest total price we could find now by $20. (For further comparison, we also saw it bundled with a copy of Far Cry 3 for $10 more two weeks ago.) It features read speeds of up to 530MB/s and write speeds of up to 240MB/s.
