When it comes to achieving the best performance from your computer, nothing beats a Solid State Drive (SSD). Right out of the box, they are significantly faster at reading/writing data than a Hard Disk Drive (HDD). But there are a few things that you have to do differently with an SSD. Here's how to safely optimize your solid-state drive.
There are numerous articles available that offer various tweaks to enhance SSD access time, ranging from disabling disk indexing to turning off Prefetch and Superfetch. Some may work for you, while others may not. Generally speaking, if you're running Windows 7 or higher, the operating system should recognize the SSD and modify its behavior accordingly. The following tweaks are entirely safe and will not harm your system in any way.
General SSD maintenance
SSDs operate differently from HDDs, and there are a couple of things you should never do to an SSD. Since SSDs have limited read/write cycles, any program that intensively accesses the SSD can shorten the drive's lifespan. Running a disk defragment program on an SSD is not recommended. As for Check Disk (CHKDSK), you'll need to contact the manufacturer of your SSD to determine if they recommend it.
Microsoft began building in support for SSDs in Windows 7 / Windows Server 2008 R2 and has expanded on it in later versions of Windows. Since the low-level operation of SSDs differs from that of HDDs, the Trim command was introduced to handle delete/format requests. To verify that Trim is on, you'll need to open an Administrative Command Prompt.

You can verify that Trim is enabled by typing the following into an Administrative Command Prompt:
fsutil behavior query DisableDeleteNotify
If the command returns a 0, then Trim is enabled. If it returns a 1, then it is not. To enable Trim, type the following into the Admin Command Prompt:
fsutil behavior set DisableDeleteNotify 0
SSD free space maintenance
SSDs do have one downside: their capacity can be smaller than that of HDDs. The capacity of SSDs is getting closer to HDDs every day, but the price for a 4 to 8TB SSD can be expensive. If you have a smaller capacity SSD, maintaining an adequate amount of free space is essential.
Now, there are two scenarios for setting up computers with SSDs: Single-drive (SSD only) and Multiple drive (SSD + HDD). Laptops are usually single-drive, and desktops are almost always multiple-drive. Here are a few ways to maintain free space.
Single-drive (SSD only)
The options here are limited. You can store your files, such as documents, photos, and music, on an external drive or in the cloud to free up space. Here are a few more ideas.
Turn off Hibernation.
With the speed of an SSD, boot times will be relatively faster than with an HDD. You'll find that you can boot your computer just as fast as if you brought it out of hibernation. And since hibernation writes the system memory to disk, you'll free up the same amount of disk space equal to the total system memory. And if you have a lot of memory, this can free up a big chunk of space on your SSD.

Turn off the virtual memory/pagefile.
Use this with caution! Technically, virtual memory is used when all of the system memory is full. If you have a large amount of system memory (64GB or more) and don't run memory-intensive software like Photoshop, you should be alright turning it off. And you'll free up a few GB's of drive space in the process.

Clean up the drive regularly.
Temporary files and browser caches are a few items you'll need to keep an eye on. Using a program like Piriform's CCleaner or Disk Cleanup that comes with Windows will take care of these files. Disk Cleanup can also be run as a scheduled task.

Multiple-drive (SSD + HDD)
This is the optimal setup. Everything applicable to a single-drive scenario also applies here. Windows and program files should be stored on the SSD. Almost anything else that Windows doesn't require for regular operation can go over to the HDD.
Move the virtual memory/pagefile.
Instead of turning it off, move it to the HDD (see the link above).
Move personal files to HDD.
Your documents, photos, and music can occupy a significant amount of space on your drive. Get them off the SSD and over to the HDD.
