i have been using the Samsung T7 Portable SSD 1TB on my pro for months and i am very satisfied with the stability. the ps4 pro uses usb 3.1 gen 1 which caps out at 5gbps. you wont see the drives full 1050mb/s rating, but it effectively saturates the interface. bloodborne loading screens dropped from 40+ seconds down to about 18 in my tests. here is why i recommend this specific model:

• thermal control: the aluminum housing prevents throttling during long sessions.
• reliability: i have had zero complaints regarding data corruption or connectivity drops.
• speed: it handles random read/write cycles much better than the stock hdd. if that is too pricey, the Crucial X8 1TB Portable SSD is another solid pick that fits your 80 dollar budget and offers nearly identical real world performance.

Quick reply while I have a sec... honestly just grab the Crucial X8 1TB Portable SSD. In my experience, its the best bang for your buck right now and fits your 80 dollar budget easily. Dont overthink the top speeds since the PS4 bottlenecks anyway. Itll make those Bloodborne load times actually bearable for once, finally.

Regarding what #1 said about the Samsung T7 Portable SSD, my load times finally stopped killing the vibe, im happy...

• You want pre-built or diy enclosures?
• Do you need DRAM or just capacity?
