External SSD for Mac.
Not happy with the Fusion drive in my iMac 27" so bought an Adata 500GB external SSD which connected by USB. This was a big improvement , but I couldn't afford the SSD with Thunderbolt 3 connection. Then I saw this X5, new, at half-price, on Ebay! Plugged it in, downloaded Monterey and used Migration Assistant to move everything over.
It is twice as fast on Read speeds and three times as fast on Write. No more spinning beach balls....Lovely.
