Which SSD to put in iMac '27 mid 2011?

Question

Solid State Drives

There is a hard disk on 2Tb.
I would like to consult which sdd is better to add from the existing ones. There are also options, if I'm not mistaken, to deliver several sdds - what do you say about this? The task is to ideally understand the optimal + best option at the moment.
Thanks in advance.

Answer 1

As far as I remember, you need to buy an upgrade kit, where there will be suction cups, screwdrivers. (although hardware store will work too, screwdrivers can be found at repair shops)
Exactly compatible SSDs:
Crucial m4 - I've had one for over 5 years, fast read/slow write, high reliability, low price
Samsung 830 - never used
INTEL 520 - now I use it as the main one, maximum read / write speed, maximum reliability, as well as the price
