Plextor 128Gb Sata 6Gb/s SSD (PX-128M5S) for $79 at MSY (Wednesday only)
Note, this is Plextor's standard level M5S SSD. Performance is apparently very similar to that of the Samsung 840, but I've read that many prefer the MLC NAND in the PX-128M5S vs the TLC NAND in the 840, due to longevity concerns surrounding TLC.
Doing a quick price match on this drive I see that Warcom.com.au are selling it for $129.80, Scorptec.com.au $111.00 (incl. delivery) and Skycomp.com.au for $125.
