Great price & storage for a PS5, complete with everything you need EXCEPT instructions. I dont expect this matters in a PC or laptop.
So for the PS5 I used a thick piece of the pad on the base, then the SSD, then a thin piece between the SSD & the top cover. If you line it all up at the securing screw end JUST leaving enough room for the spacer the connection end will be ok. The top cover then snaps in (don`t slide it as it will pick up on the silicon pad) but do not be too close to the connection end as you can`t get the angle to insert the assembled SSD. I did find I could slide the top cover back slightly to allow install as I was initially too close.
Read speed test was just under 5K but PS5 is quite happy.
