I'm operating from Germany.
I don't have a limit on budget, I just want to make sure it's simply worth the money I pay and that the drive really has all the useful features that can be good for an SSD.
I'm rather interested if I should look for some requirements, for example:
NAND type(MLC, TLC, V-NAND MLC, V-NAND TLC, cMLC, eMLC, HET MLC, SLC)
NAND mode(Toggle, asynchron, synchron
NAND assembly(16nm, 19nm, 20nm, 21nm, 24nm, 25nm, 27nm, 32nm, 34nm, 40nm)
or other special features like capacitors.
You can take a look at that portal here:
A lot features can be chosen there to narrow it down to a selection that can be used to choose a drive from.
