I've been in the market for a nice portable stand alone SSD. I ran across this deal on B&H and Amazon but it looks like amazon is back to regular price.
B&H has the new Crucial X8 SSD drives on sale. I picked up the 1TB for 129 and change with the payboo card.
It seems to be similar product to the T5 but isn't limited by the SATA interface and can achieve speeds double of a T5 from what I've seen online. Performance looks to be inline with the new Sandisk Extreme Pro SSD coming out soon for about half the price. I'm a little leery of this only having a three year warranty vs the five year offered on other crucial SSD products.
