Solid State Drives (SSD’s) are a relatively new storage technology. SSD’s started to become common in consumer devices in 2011. Unfortunately, many computers today still don’t include them as standard to cut costs despite SSD’s offering perhaps the biggest performance increase for computers in the past 2 decades.
Solid State Drives are much, much faster than Hard Disk Drives. HDD’s are a mechanical device. This means they generate heat, noise and vibrations.
Hard Disk Drives have a number of platters that spin at high speeds while a head reads the data on the disk, kind of similar to an old vinyl record. There is little room for error in the mechanics, as this head floats on a tiny pocket of air above the disk, only a few nanometres apart. Even a particle of smoke between the head and platter could cause a collision and loss of data.
Solid State Drives are a non-mechanical part, as the name suggests. Because there is no need for a head to have to physically move as the disk spins, this means it can access data much faster… Roughly 10-20x’s faster!
If your computer is running off a HDD, you may notice it’s very slow, especially if this computer originally ran Windows 7 and has been upgraded to Windows 10. Windows 10 likes to access the HDD a lot which means while you may not be copying a lot of data, the HDD is still being read from constantly causing a bottleneck in performance.
If your computer is slow and it’s only a few years old, it’s probably time to retire the old Hard Disk Drive and upgrade to a Solid State Device. The process to upgrade is easy and won’t brake the bank.
