I’ve been searching for an upgrade finding either 42mm or 22×42 or 2242 brings up results however not many options exist and knowing reliable brand to choose is another game altogether.
Transcend seems to be the highest performance drive around with 560mbs write and 300mbs read. ZTC seems to be another viable choice but Kingspec and another King brand seem to be on the low end of price and probably wont be very good.
Personally I’m concerned about the heat that these SSD produce near other components and I’ve instead gone for a USB solution and will get steam games to install to this instead. I’ve ordered a ADATA 256gb for £78 last week which will be 400mbs read and write speeds if not faster and I’ve already got a 256gb SSD in the form of a thumb drive all-beit a rather wide one but fits well and doesn’t get in the way of other ports as some reviews suggest well perhaps the headphone port or hdmi but I don’t plan to use those often and could always use a hub.
