Hi guys,
I would really appreciate your advice. I've buy an SSD disc (ADATA SP550, 480GB) into my mid 2010 13' MacBook Pro. I've replaced them and made clean install of macOS Sierra from bootable USB flash disc. It was running perfectly, much faster than old HDD, I've made also TRIM of SSD through terminal. But after half an hour the computer has stuck and after restart it doesn't boot. I can see the apple logo and process of starting, but it shuts down almost immediately. I wanted to reinstall the macOS, but I can't even erase the SSD through the disk utility, computer see them, but I don't have access to them, and, if I want to install the macOS, there is not option to install them to those SSD.
Thanks a lot!

Just ideas:

1. The SSD, being new, could be a lemon.

or

2. Your screwing around with TRIM messed things up! I went to Wikipedia and there is a bit of a warning about TRIM in the macOS / OS X section:

https://en.wikipedia.org/wiki/Trim_(computing)
 
Thanks for reaction! Do you think, if the problem is caused by TRIM, that SSD is damaged, or is it possible to format/repair/do something with them?
Thank you!
 
I think that you would not have got TRIM to work at all, if there was a problem with your specific drive, and TRIM.
And, probably would not kill the drive, as your example sounds like a failed drive.

Or, more likely, is that you damaged the SATA cable when you replaced your hard drive.
The cables can be quite fragile, and a cable problem may show up immediately, or might show up at some later date. The cable damage is always something to consider, and your symptoms (computer stalled, then will shut off during boot) are typical of a faulty drive, or failed SATA cable.
 
Can you boot into the recovery mode (cmd -R)?
Yes, It's possible to boot into recovery mode. But It's not possible to reinstall the macOS, because there is not option to install them to those SSD.

The SATA cable should be OK, because after connecting old HDD disk, Mac works normally (but slowly :D)

Your internal SSD shows up and you can transfer files to it under those conditions? What does Disk Utility have to say about the state of your SSD?
 
Maybe you should hold down the 'alt' key during start-up and choose your boot disk. You should be able to reinstall it from there.

It´s weird. When I open Disk Utility in recovery mode, it shows, that all capacity is used, no idea why. There is option like rescue, when I try it, it says like there is damage, You have to repair it from Recovery (which I´m now in, the cmd-R) When I try to delete (format) disk, it says, that the process failed.

Based on what you described so far, it still sounds like a bad internal SATA cable. It is very common for a borderline cable to work okay with a HDD and not with a SSD due to the higher transfer rates required with the SSD.

The true test would be to put the SSD in an external USB enclosure and see how it works there. If it works in the enclosure, albeit more slowly, that proves it is the internal cable.

I took your advise and bought an external USB enclosure today, and the computer doesn't even see the SSD drive. I tried it in my friend's windows computer as well and those computer connect the disc, but I'm not able to open the content of them.

If Disk Utility can't even see the drive in the USB enclosure, then it sounds like your drive has died.
