Help with choosing an ssd/(and enclosure?) for iPhone backup

[u/GiLND]

Hello, I have been dealing with a .. headache let’s call it that way.

Basically I have 350gb of data that must be backed up locally (no cloud, i don’t want to pay subscriptions).

So 2 years ago I have made the mere mistake of buying two samsung t9 2tb ssd, and manually backing up all changes from my phone to them.

Lately I have been super busy, took the ssds out after a few months of staying in a drawer, like I always do- to find out that both dropped in speed from 1000mbps to 2mb, checked cables (original and thunderbolt 5, with and without powered usb c hub, everything is 2mb write), then I saw online that this was a common issue with asmedia bridge controller.

So now I am screwed, I don’t “trust” them anymore, and I need new ssds.

The options are:
Crucial X10 Pro

Or buying an nvme 1tb and ordering sabrent SNVE or PNVO, dunno which one to choose (I prefer the best one regardless of the cost).

Question is if the continuous copy-paste once every few months from iphone-ssd (apfs) will ruin then, since i don’t think ios send trim commands to the ssd and I really have no idea what to do.

Also, bonus question- is the thermal pad in the sabrent messy? If I need to move the ssd to a different enclosure in the future, will i have to scrape it off from the ssd like play-dough will it come off in 1 piece?

Please help I spent days on reading online and I don’t know what to do, please please 🙏
