Good find and TC you could clone the drive to any external drive using a USB to SATA adaptor or just hook it in a spare SATA port Macrium does a really good job and all you need do is to clone it back when you get the new drive. Macrium Reflect Free I have attached pics of how I do it but you might have a preference for something else :)There's no need for MemTest as we have found your problem, it's your SSD overheating. Can you try to install Windows on the HDD and unplug your SSD when running Windows on the HDD.
NB You will be notified of a bug patch do that before cloning
Now for my two cents worth I stick with the better known drives (SSD especially) Samsung, SanDisk, Crucial and Corsair being my line of choice and they are all around the same price mark for the GB's you get. I must admit I do like Samsung because of their technology and they make their own controller - which in the past has been a failing point with SSD's so I know I am safe.
