Flash RAM — the storage technology within SSDs — is immune to the violent disasters and wear-and-tear that can crash a hard drive. But SSDs have their own problems. Every time you write to flash RAM, you bring it a step closer to the day it fails.
Fortunately, those steps are very tiny. If you avoid unnecessary writing, your SSD will probably last until you want to replace it with something better. But it's still a good idea to avoid unnecessary writing. You can do that by turning off these four Windows settings.
An extremely fragmented hard drive can slow down a PC, but fragmentation is irrelevant on an SSD. Worse, it writes all over the place. Best to turn it off.
In Windows 7, Click the Start button, type disk defrag¸ and select Disk Defragmenter. If the big button near the top-right corner says "Turn on schedule...," no problem; you don't have to change a thing. But if it says "Configure schedule...," click the button and uncheck Run on a schedule (recommended).
In Windows 8, search for disk defrag and select Defragment and optimize your drives. Once in the program, click the Change Settings button. If Run on a schedule (recommended) is checked, uncheck it.
If you're running more programs than fit in your physical RAM, Windows swaps some of them to your internal drive. If that drive is an SSD, that's not good.
Check out my article on virtual memory to learn more about this issue and learn how to turn it off.
No, Superfetch is not a canine superhero, but a cache-like Windows feature that's supposed to improve performance. It didn't really help all that much with hard drives, and it actually slows down SSDs as it wears them down.
To disable Superfetch, search and select services.msc. In the resulting Services window, scroll down to and double-click on Superfetch. Pull down the Startup type menu and select Disabled.
When you put a Windows PC into the energy-saving sleep mode, it still uses a trickle of electricity. When you hibernate it, you shut down the hardware entirely.
But hibernation also copies everything in RAM to the C: drive — wearing out the SSD just a little bit.
You can simply not hibernate. Or, to be safe, you can disable it. If you're using Windows 7, follow Microsoft's instructions. In Windows 8, don't worry about it; hibernation is disabled by default.
