If you want something faster than an external hard drive, and better than a USB Flash drive, you can build an external SSD drive with an SSD and an enclosure. I built a 256GB USB 3.1 external SSD for less than $70 that works great on my Mac. Learn how to build your own.

Here are the two items I show in the video:
SK Aluminum M.2 NVME SSD Enclosure
Silicon Power 256GB – NVMe M.2 PCIe Gen3x4 2280 TLC SSD
Thanks Gary. Is the SSD you are using sold as an “internal” drive or “external” drive? Or doesn’t it matter ? ( I’m assuming it doesn’t)
Terry: You can see it with the link above.
Hi Gary, have a 256gb SSD in an OWC Thunderbay 4, would a USB C external drive be faster? Another Terry
Terry: Thunderbolt is faster than USB 3.1. "USB-C" is not a connection type but a port -- you probably mean USB 3.1.
Can you use this also with IPAD 2 6th Gen - 2018
Godfried: No. That has a Lightning connector, not a USB connector.
Can you make this external drive a boot drive, or will it just be a data drive?
More: It can be a boot drive if you have a reason to use that. I'm using the exact one I show in this video as a Big Sur beta test boot drive now, so I don't have to have Big Sur on my MacBook for every day things.
I have a mid2011 iMac running off an external Elgato 256gm SSD on my thunderbolt 1 port works great but too small. there are no external thunderbolt drives available anywhere. can you give a solution using your hint for a 500 GB SSD with a thunderbolt exclosure?
