Half the price per GB and I'll probably get one.
Still a bit pricey for use at home, at least for me (unless your a money bags of course).
The 480GB version works out at around 79p per GB.
Same size SATA SSDs are ~30p per GB range. (although of course limited speed to around 550MB/s).
So currently, these are 2-3 times the price per GB, to give you 2-3 times the speed of a SATA SSD.
As a comparison, SATA SSDs were around the same 79 Pence per GB in late 2011/early 2012. So hopefully these will drop to 25p per GB (or less) by 2018.
Get the price down to around 55p per GB (so mid to late 2016?), and I might be tempted.
