This feels like a last gasp for HDDs seeming SSDs have improved reliability and come down in price for $/GB. I recently ordered a couple of 256GB Sandisk Ultra Plus SSDs for $130 + shipping. $0.53/GB aint that bad. Nevermind it isn't the fastest drive around so long as it is faster than any standard HDD. It was announced Nov 6, 2013 and as of Jan 17, 2014 has yet to ship from Amazon or NewEgg. Current 1.5TB & 2TB 2.5-inch from WD HDD tend to surpass 12.5mm in thickness making them wholly unsuitable for any Macbook Pro to accommodate. The often floated price for the 2TB is $129. To my eyes this is great value but no one online is selling em. For your convenience here are the model numbers of the differing capacities. These were found from the PDF that can be seen here. 1.5TB ST1500LM006 ST1500LM007 ST1500LM010 2TB ST2000LM003 ST2000LM004 ST2000LM006 I look forward to making the 2TB Seagate HDD + 256GB Sandisk SSD into a Fusion Drive. For those curious the 2TB is less than $0.07/GB.
