What is the opinion of Reddit about the
SAMSUNG T7 Touch Portable SSD 2TB – Up to 1050MB/s – USB 3.2 External Solid State Drive, Black (MU-PC2T0K/WW)?

I amde a mistake, it is a late 2012 and not late 2011 iMac. As it is much moe difficult to replace, I would rather try using an EXTERNAL SSD.

Someone was suggesting here this one: Samsung T7

Any other recommendation?

SSD’s travel well and are quick.
