Recently I upgraded my MacBook Air with a new Hard disk of bigger size. I am now left with the old one and am not sure how to reuse the old one. I heard that there are caddies available but they are expensive. I wanted to hear if you have any suggestions?
Also, if I have to buy a caddy, do you have any specific recommendations?
I guess these guys sell caddy?
Is it a hard drive or an ssd?
You do not need a mac specific caddy. Some companies will charge multiples in price for including the word apple or mac.
For example this product will work for 2.5 inch ssd/hdd. The key word you're after is enclosure.
