I've got an M4 Mini on the way (supposedly coming Friday). I'm considering getting a TerraMaster D8 Hybrid to sit along side it. It can take 4 up to 22TB drives (HDD or SSD), and 4 up to 8TB M.2 NVMes. This would let me attach all my old drives as is and/or potentially move data from my old 2TB HDDs over to faster SSD drives or NVMe storage as I see fit. It's only USB 3.2 (10Gbit), but it's also fairly dirt cheap for that many storage bays.

If you want a small portable drive for your laptop though, then like Neuro said, the Samsung T7s work well. I've got a 2TB T7 Shield kicking around to not use all my internal laptop storage. You can likely snag a deal on Black Friday, or maybe one of the many pre-BF sales.
