How to get rid of macbook pro freezing after installing ssd?

Question

macOS

I installed an SSD KINGSTON SV300S37A480G in Macbook pro (early 2011), and there were periodic system freezes during operation, for 15-25 seconds. Even itunes music stops playing. I insert the old hard - everything is fine, that is, the problem is not in the cable. Carry the drive back, is it an incompatibility problem with the laptop, or can something be configured?

Answer 1

Look Presumably in the direction of these 2 problems:
1. Saving email. Energy and the corresponding configured falling asleep of the hard drive
2. TRIM, see the info on the Internet, you can start here habrahabr.ru/post/143659
