SanDisk 1TB Extreme Portable SSD
This is what I use:

It's very fast and I've been using it every day for 1.5 years for TimeMachine backups.
Best all around would be the 2nd gen Sandisk.
At this level the performance difference between 2tb and 4tb is negligible.
I've written more in depth here. Samsung has recently released the T7 Tough which performs better than the T7 but still not up to the Sandisk. I wrote about it here.
Get a 1TB SSD. The best of both worlds, speed and shockproof, $83.

Should fit in your shirt pocket.
I've been using a $90 SanDisk 1TB SSD drive. There's 5 months of clips from Sentry being on 24/7 and it's not even half full.
