Someone suggested we should have a feature called Geeks and Geezers, using the Geek heading for the more technical stuff and Geezers for the simpler stuff. Here’s an article that I think could work for both groups – the difference between SSD and HDD.
Both terms refer to storage on your computer. SSD – stands for Solid State Dive and HHD for Hard Disk Drive. Though, you’ll often see the term hard drive used to refer to both of them as hard drive is sometimes used to refer to any internal drive on a PC.
The difference between an HDD and SSD is that an SSD has no moving parts. SSDs are a more complex version of memory cards and flash drives.
I think we all have heard the sound of an HDD spinning or starting up. An HDD uses a mechanical arm to write and find data on the disk. SSDs have an embedded processor, basically a brain, that finds and writes data. SSDs can usually open data around 30% faster than HDDs. SSDs are also much quieter. They use less power, produce less heat, and don’t vibrate.
It’s also impossible for an SSD to become fragmented. Because the mechanical arm on an HDD takes has to work harder if the data is separated, it’s best to keep data in a block. This makes no difference to an SSD drive, it can instantly find data anywhere.
SSDs cost more than HDD. But the price gap is narrowing. If you need an ultra-large capacity in a desktop hard drive, HDD might also be a better choice for you.
SSDs, like any other storage medium, can wear out over time, but HDDs face their own set of durability issues and modern SSDs and HDDs probably come up even when it comes to measuring longevity.
One thought on “Tech Terms: SSD vs. HDD”
What a great idea for geeks & geezers maybe one could also have one for older geezers for us over 85 as I am finding it hard to keep up .. Gone are the days I remember being involved with reel to reel and valves. A pat on the back for you doing a fine job .but I still miss World Start Kind regards Brian C.
