Yes you can use a Samsung 850 EVO 2.5" SSD in your system swapping out your current HD. Follow this IFIXIT guide: MacBook Pro 13" Unibody Late 2011 Hard Drive Replacement

To make this easy get either a USB or FireWire (being faster) external case to hold your new SSD so you can prep it up.

Next you'll want to download from the App store the OS installer.

First you'll want to use Disk Utility to create a GUID partition map and a Mac OS Extended (Journaled) partition on your new SSD. Now run the OS installer and install the OS onto your new SSD. At the end of the OS install process the installer will ask you if you want to migrate your user accounts, apps & data over point to your current HD and all of your stuff will be copied over. The last step is to swap out your drives and thats it!

Two things you should do before you start:

- Make sure your systems firmware is up to date. Follow this Apple T/N to check: About EFI and SMC firmware updates for Intel-based Mac computers If you have something newer thats works to.

- A common issue with this series is the HD SATA cable breaking down and if you have a SATA II (3.0 Gb/s) drive currently in your system the cable may not support the faster SATA III (6.0 Gb/s) SSD you're putting in. I would recommend replacing it at the same time you put the SSD in. Here's what you need: MacBook Pro 13" Unibody (Mid 2012) Hard Drive Cable - Apple P/N: 923-0104

Dear Dan,

I have read a lot about this issue and your explanations seem very clear and it makes sense to upgrade the hd sata cable to support 6.0 Gb/s SSD speed. However, because the Cable you just posted is for the mid 2012 version, is it compatible with early 2011 MacBook Pro ??

Replacing the cable and installing the SSD EVO 850 should it go up to 6.0 Gb/s ?thanks in advance!

I use the 2012 model's cable in the 2010 & 11 systems as it's the same part but a better design. If you had both cables you would see some design differences between the two cables (thickness) the extra effort was due to the higher data rate the SSD drives can put through

Think like how a car runs on a dirt road Vs a paved highway. The car can run on either, but would be limited on how fast on the dirt road and would pickup a lot of dust in the process.

HDD's data throughput is still less then what SSD's can put out so the design of the SATA cable needs to be optimized for the higher throughput which the newer designed cable offers.

Even still I always apply some electricians tape onto the uppercase when the cable rests to help isolate it from the rough aluminum so it does not abrade.

The limits of the systems SATA port is the issue so if you have a SATA III interface in your system it will run the Samsung at SSD SATA III (6.0 GB/s). The 2011 models do have an issue within the optical drive SATA port so it can mess things up if this port is the startup drive with a SATA III drive.

Yes, you can use it.

All SATA based systems can support a SATA SSD. The only issue you face is the systems SATA I/O speed and the speed of the SSD. In this case the Samsung 850 EVO SSD is an auto sense drive so it will match the systems SATA port's I/O speed! Not all SSD's do this so if you have a slower I/O speed system i.e. SATA II (3.0 Gb/s) a newer fixed speed drive i.e. SATA III (6.0 Gb/s) won't work.

Bottomline: Review the drives spec sheet to make sure it supports the SATA speed of your system. As an example Samsung 850 EVO spec sheet Note the Interface line, what ever drive you get needs to support what your system uses.
