Questions and advice on 2011 MBP SSD upgrade

Hello,

I have an early 2011 15" MBP, 2.2 i7, with the stock 500 GB Hitachi hard drive. I identified an SSD that I want to use to upgrade, especially given the size (500GB) and price ~$275:

First off, I was wondering if anyone here had experience with the Samsung SSDs. I looked at some of the threads here as well as upgrade instructions for an MBP of the same exact specifications on another website for an OWC SSD:

My second question is, would this Samsung SSD be compatible with full 6G speeds if in the main bay? I don't know much about hard drives, but could someone explain to me the difference between SATA II/III and 3G/6G?

My last question is if anyone knows where I can find a good video or the instructions necessary for upgrading my old HDD with the SSD.

Thanks for the help.

I just installed the same Samsung SSD (840 series, 500 GB) in the same type of MBP about a week ago, here are instructions I wrote up for someone else on another thread (post #4).

My one week of experience with the SSD has been positive, no complaints, very fast and noticeable improvement over the stock HDD.

SATA III is the type of connection used in the main bay for the HDD / SDD. Some people take out the DVD drive and install a second HDD / SDD in that space, as I recall the connection in the 2011 MBP for *that* is the older slower SATA II type.

If you're just swapping your existing harddrive for a new SDD there's nothing to think about or worry about. The Samsung 840 is SATA III and will take advantage of the full speed capability of the main bay.

Your MBP supports SATA 3 at 6gbs but the current drive doesn't work at that speed so the current link is 3gbs. If your put in a drive that supports 6gbs you will see the higher speed. The devices negotiate to the highest common speed.

I'm planning to make a similar change in a month or two.

Thanks for the assistance. The item was marked as "under review" by Amazon so I did not order. It was removed from this list but the price increased beyond $300; however, I found it on Newegg and used a $60 promo code to discount it even further from the price listed there, and I just ordered it:

Deal expires midnight pacific time, if anyone is interested. Promo code found here:

Soot, I had a quick look at your thread. Looks very helpful, will use it when installing the SSD.

When reading reviews I came across "TRIM" and reviewers sometimes posted about installing firmware on Windows because it was easier. Is any of this necessary, or is it unrelated/nothing to worry about? Thanks.

EDIT: I just realized ChunkAhoy mentioned TRIM. What exactly does TRIM do for your SSD?

You can with a bootable ISO image but still painful though.
I think we all are hoping that Samsung will get with the times and give
us Mac users a native FW upgrade path.

Samsung is an Asian company. Firmware updates are software.

Not going to happen. Be grateful that you can do it by booting an USB stick.

I recently installed my Samsung 840 Series SSD any everything seems to be going well. I enabled Trim and found some suggestions here on other SSD optimizations.

My question is what are the drawbacks of disabling hibernation? I am having some trouble understanding that. I understand a benefit is gaining back the disk space used by the sleep image and not constantly writing the contents of memory to disk. But what negative effects are there? Is the only drawback that I would lose my current memory in the event of battery dying? What would happen to open applications when the laptop is awakened from sleep? Or in other words, what are the benefits of keeping hibernation on? Thanks for the help.
