![]() Because flash memory cells can only be written to a certain number of times, solid state drives technically have a limited lifespan, moreso than their disk drive predecessors. This leads me to address the elephant in the room, which is longevity. But now that those prices are dropping, SSDs come standard on most new computers, and even more people are replacing their old hard drives with modern solid state alternatives. The advantages of SSDs are clear: they’re exponentially faster, they’re entirely silent, they’re more durable, and they’re immune from issues like fragmentation.Īs with any new technology, they were fairly rare until recently because of their high prices. Unlike their disk-based predecessors, SSDs are more like a series of very high performance USB keys squished together. It’s like having a series of very high performance USB keys squished into a box. This is broadly true, and I will show you how to check for and enable TRIM support on your drives, but first it’s important to take a step back and understand what we’re talking about.Īn HDD encodes data onto a magnetic coating on a spinning disk inside the drive.Īn SSD, on the other hand, is just a network of flash memory cells assembled into a drive enclosure, meaning it has no moving parts. ![]() You’ve probably heard that SSDs have a lifespan, and that you can prolong that lifespan by enabling something called TRIM.
