Can someone help me choose a new SSD please.

My old mechanical D has recently died and I'm currently relying on an almost full 250gb C SSD for all gaming pleasures & everything else.. I'm looking for a new SSD largest/quickest/most durable in the £200 - 250 price range (preferably as cheap as possible) but haven't much of a clue, any advice/recommendations would be greatly appreciated.

2.5 or m.2?

Well do you want cheap as possible or quickest-most-durable? lol

If you want large and cheap check out the Samsung QVO series.

If you wan fast and durable (but still reasonable price) check out Samsung 970 Evo NVMe.

If you find something else and want me to look over the specs post it.

Many thanks to folk for replying so quickly..

If this is any use to people, my mainboard is a Micro-Star International H310-F PRO 9 (MS-7B25)

A Samsung 970 NVME Evo has been suggested by someone else also, would one of these be compatible with my mb too pyro?

Your MB doesn't seem to have any m.2 slot, so it will have to be a sata SSD. In my country Crucial MX500 is the best value, Samsung Evo 860 is a little pricier, but I think it has better warranty (more Terabytes written). For your budget you should be able to get even 2TB.

Samsung tend to be overpriced in my experience, but still quality products.

Other good brands are Crucial, Adata, Western Digital, and Sabrent (I got a Sabrent 2TB drive for the cost of a 500 GB Samsung and it is just as good).

Unless you're doing a lot of data stuff (video editing, music, etc) I wouldn't worry about rewrites and stuff like that; installing and uninstalling games is not going to take a toll on your SSD. That's essentially what you're paying for when you go "high end"; a specific quality you don't really need.
