macbook prossdupgrade
I'm planning on upgrading my 120GB HDD to a 128GB SSD but I'm not sure which SSD will be compatible with my MacBook.
My specs: MacBook late 2007 / Santa Rosa 2.2GHz / 4GB RAM
Preferably, I'd like to get the fastest SSD that would be compatible for my MacBook but the SATA versions have been updated three times since this MacBook was released I'm not sure which would be the best.
You probably have one of the following enabled that could explain the power drain.
Power Nap or Wake on WiFi, disable them,
or read the small print that says what it will do in sleep :)
Also as said earlier, open the Console and type "Wake" in the search window of the Console.
Now look who and what is waking it up and what is it for what reason and what is it doing about it.
As for your question why is it consuming more power, well you added more lights to the Christmas tree.
For example when HDD sleeps it does not consumes any power. The cussing SSD does consume power since it reshuffle it self from time to time, that is normal for SSD to refresh its memory cells.
UPDATE:
according to apple, you computer does not support the Power Nap mode settings thus enable/disable activity during the sleep.
So back to the Console reports:
Type "Wake" and look what is waking it up or keeping it awake based on time stamps.
Going on a limb, I would say it is your Trim support for the SSD, that you will find in the Console.
The TRIM command is an important disk command for SSDs that keeps your flash memory appropriately cycled so that you can achieve faster read and write speeds, as well as a longer lifespan for your SSD.
As long as you can confirm the laptop is indeed from mid-2012 (later models have the memory soldered in), then these specs should work for you with either a 13" or 15" laptop (Apple started soldering memory in 17" laptops after 2011):

As far as hard drives go, I'd personally recommend a Crucial SSD, but yes, any solid state drive will work.
Hope this helps!

I upgraded a similar era Macbook a while ago. In all likelihood you are unlikely to be able to buy an SSD that will not max out the BUS speed available to it on a machine that old.
That particular Macbook has a SATA I (1.5Gbps) interface for it's existing hard drive. SATA III (6Gbps) SSD drives have been the standard for many years now, although you may be able to get a bargain bucket SATA II device (3Gbps). Basically, I would get the cheapest SSD you can for the capacity you require that is at least SATA II (you don't need it for the speed, but a SATA I one will be based on older technology that may have a shorter lifespan than a newer drive). It is almost certain to be faster than your machine can handle, so there is no point getting a particularly recent or fast one.
