13 inch early 2011 mbp ssd

[abcdefg12345]

I have a 13 inch MBP early 2011 and i had upgraded the memory from 4gb to 8gb and hdd from 320gb to 1tb last year and I'm thinking of getting an SSD and I'm not sure what to get i was looking at:

OWC DIY Kit: Data Doubler + 120GB OWC Mercury Electra 6G SSD Drive Bundle + 5 Piece Toolkit. $139.40 which is on sale now $119.99

or

OWC DIY Kit: Data Doubler + 120GB OWC Mercury EXTREME Pro 6G SSD Drive Bundle + 5 Piece Toolkit. $179.49 also on sale $159.00

and thinking of using the data doubler to use normal hdd instead of optical drive and have the SSD as the main drive

would it make any noticeable difference if i go for mercury extreme over mercury electra

and should i use the one TB HDD that i bought last year or 320gb HDD that came with my mac in place of the optical drive.
i currently have my 1 tb hdd partitioned in half and I've used about 250gb out of 500 in my main partition and my second one is empty

since the 1 tb hdd is bit more noisy should i use the 320gb in the data doubler and have the 1tb hdd in external enclosure.

so what 2 drives combination is good for me. I'm planing on keeping my mac for another 2 to 3 years

and will this affect battery usage and does ejecting the 2nd hdd when not in use help improve performance, heat and battery.

First I would keep the 1 TB drive. One the other hand I would for another brand, maybe Samsung with Evo or Crucial, there you should get more for your money.

I got the samsung 840 evo and I absolutely love it. I got the 750gb one so I don't know much about the putting a drive in the optical bay. Although I do know that some 2011's don't operate well with a drive in the optical bay( I remember reading this while doing my research and I think it only applied to the 17" 2011 Mbp but you may want to look into it).

I have an early-2011 13", as per my sig I get the full 6G speed to the Crucial 120GB SSD in the optical bay as well as 6G to the HDD, I now have a Hitachi 7200rpm 1TB HDD in the std drive bay so full motion detection etc.

Works seamlessly, faultlessly and flies....

The Samsung 840 Pro is the best SSD on the market IMO. It's what I have in my Early-2011 13". The 840 EVO, on the other hand, is the best SSD for the money. You can't go wrong with Crucial, Intel, OWC, and some other brands but Samsung is generally regarded as the best.
