I was looking for a decent M.2 SSD for my upgrade and finally decided on this one due to tight budget. Looks like a decent one to me.
Not the cheapest historically, but very close with the latest one from Shopping Express last week ($139.50 + Shipping).
Apparently will fit into a PS5 too from this post: https://www.ozbargain.com.au/comment/10838893/redir

One of the fastest around and yes, PS5 compatible.
