New to SSD's; want SSD as SECOND drive for games on Windows 7 with HDD as main drive

Formatting the SSD
Press start, right click on Computer and then select Manage, a window should open up, double click Storage, double click Disk Management, and wait for it to load up, you should then see disk 0, disk 1 etc... there'll only be more than those 2 if you have more than 2 drives connected, that includes USBs and external hard drives. Disk 0 should contain your boot partition and OS as it's your main drive, disk 1 will most likely be your SSD if theres no other drives connected, you should see in the partitioning area as it being Unallocated, right click on the Unallocated space and select New Simple Volume, you should then be greeted with the New Simple Volume Wizard, click Next, this is where you configure the amount of space the partition will contain, it will automatically select all the avalible space, if you are happy with that click Next, it will automatically assign the nearest drive letter, the letter selected will depend on how many other drive connected and if you have an optical drive (CD/DVD drive), just click next, the File System will auto select NTFS and Allocation Unit Size should auto select Default, the Volume label can be left as is if you so wish or you can change it to something more recognisable such as "SSD", what ever label it's given will be the drive name in Computer area, the last two tick boxes can be left as they are, click Next and you should then be given the overview of the settings, if they are fine click Finish if not click Back till your reach the area where the settings are incorrect, your partition will now be created, I have before experienced it not giving it a drive letter, so relook in the partitioning are for that drive and it should have the label you created and a drive letter (if its there then thats fine, if theres no assigned letter, right click and select Change Drive Letter and Path..., click Add, then Ok on the dialog box and it should now have a letter), its size and format (NTFS) and say Healthy (primary partition). You have now successfully created a partition, close the window and open up Computer and your SSD should be listed.

Getting the best out of your SSD
To get the best out of your SSD, it would be a wise idea to install your OS on there and any other frequently used programs and your games, programs you don't use very often you should install on the HDD as well as files like documents, pictures and music. Your SSD is great for speed but not for storage, every time a file is written to the SSD, it degrades the chips inside ever so slightly, but reading from the SSD isn't as bad, therefore constantly changing files that are kept on the SSD like a document will degrade it faster than something else like reading the OS or reading the game files, and most word processing programs like MS Word create a temp file of the document in that folder (which adds more writing to the SSD) and then writes it to the actual file after the document is saved, when the document is then closed, it has to delete the temp file and re-write the values on the SSD to 0 or null being the same thing.
It's also advantageous to move as many programs's temp folders as possible to the HDD as these will be the areas where a lot of reading and writing will happen, and other folders like Downloads, Documents, Pictures etc... Can have there default locations moved to the HDD so when you save something in there it will be saved to the HDD not the SSD but still look like there in the default locations so you would have to go to Computer, then open your HDD and sift through to find your folder containing your documents etc... So what I'm saying here, by moving its default location, you could still go to Libraries and open up the Documents folder like you usually would to access the files within only the files are stored on the HDD not the SSD To do this it would be advisable to create the necessary folders on the HDD ie Documents, Pictures, Music etc.. Then go back to your Libraries area, right click on one, click Properties, Include Folder, navigate to the corresponding folder on the HDD and select, then click Set Save Location, it should now have a tick next to the HDD path, do this with all the Library folders and job done.

Things you should know
Another thing to note with SSDs is that while it's good to defrag a HDD, it's bad to defrag a SSD, you can by all means continue to defrag the HDD, just make sure the settings to defrag the SSD are off, this process reorders files on the drive so that they are accessible faster however, on an SSD it's read and write speeds are then same across the entire drive so there's no need and also adds to the amount of writes to the drive. Also filling them up to the brim with data is also bad for the drive...
