Hello,
can you please tell me if the "Crucial CT256M550SSD1 256GB CRUCIAL M550 SSD SATA, 2.5IN 7MM SSD /W 9,5MM" is compatible with a mid 2010 15" MacBook Pro ?

On crucial.com I found the CT256M550SSD3 but the version number is not exaclty as the one I want to buy (CT256M550SSD1 vs CT256M550SSD3 at the end)

I already have a SSD in my mbp but would like to change it because it has became super slow.

cheers
Tex

The "D3" designates an mSATA drive. For SATA, you need a "D1" drive. I have a Crucial 240GB M500 in my 2010 15"MBP, and it works great. With the original Hitachi drive, bootup was painfully slow. Now, even with Mavericks installed, start time from power on to desktop, less password input time, is usually about 7 seconds.
 
I put an OCZ Vertex 2 128GB SSD in my 2010 15" almost two years ago. It was a profound upgrade. Put a lot of life back into a 3 year old machine before I replaced it with a 13" rMBP last month.

Do you have TRIM enabled on the drive you have in now? I know a lot of drives say they don't need it, but I found my drive ran much faster with it enabled once it was more than 50%-60% full.

If you are looking at replacements, I can vouch for the Crucial MX100. We got 6 of the 256GB versions to put in Windows workstations at work. They have worked phenomenally for 5 months.

ok thanks for the explanations

How do I enable trim in Yosemite ? EDIT: http://www.cindori.org/trim-enabler-and-yosemite/

My current SSD is a SAMSUNG SSD PB22-JS 256GB.

Those are my current speeds

2010 mbp only has SATA II, so ~250mb/s is as fast as the interface goes. Yes, the SSD is capable of faster. Still faster than a HD.
