- SSDs use technology called flash storage that’s controlled entirely by electronic transistors. An SSD differs from a standard HDD (hard disk drive) because it uses no moving parts. An HDD uses a magnetic spinning disk and a high-speed arm to load and save data. This process is much slower than the read/write speeds you can get from an SSD.

Jul 26, 2024 · Versatile, fast, and more affordable than ever, SSDs are what modern PCs use for their boot drives (and, increasingly, for secondary storage). They aren't quite as cheap as HDDs, but they...

The traditional spinning hard disk drive is the basic non-volatile storage on a computer. That is, information on it doesn't "go away" when you turn off the system, unlike data stored in RAM. A hard drive is essentially a metal platter with a magnetic coating that stores your data. A read/write head on an arm (or a set of them) accesses the data wh...
Hard disk drive technology is relatively ancient (in terms of computer history, anyway). The IBM 650 RAMAC hard drive from 1956 used used a whopping total of 50 24-inch-wide platters to hold a mere 3.75MB of storage space. That's roughly the size of a single album track you might streamtoday, stored in the physical space that could hold two commerc...
Both solid-state and hard drives do the same job: They boot your system, and store your applications and personal files. But each type of storage has its own unique traits. How do they differ, and why would you want to get one over the other?
The overall takeaway? SSDs work best for most consumer use cases. If it weren't for the price and capacity issues, SSDs would be the hands-down winners. That said, there are still a few situations where a hard disk may be a better choice.
Once rare, solid-state drives are now the go-to technology for local data storage. They're no longer prohibitively expensive, though they're still a bit too costly to fully replace the terabytes of data that some users have in their PCs and Macs for mass storage that doesn't need to be fast, just simply there. For external drives or desktop PCs wit...

Sep 16, 2024 · Put simply, an SSD isn’t the same as a hard drive. Hard drives use magnetically sensitive platters which are moved by a motor, whereas an SSD uses flash memory without any moving parts, meaning they are faster.
May 24, 2018 · Do you like your storage cheap and plentiful, or fast and safe? Here's how to choose between a traditional hard drive and a solid-state drive in your next PC.
Jul 15, 2024 · Down to the very basics, an SSD and an HDD do basically the same thing… but in very different ways. Whereas a Hard Drive uses platters to store memory, an SSD uses interconnected flash-memory chips and doesn’t require a moving arm/head to read memory.
Aug 29, 2022 · SSDs, as the “solid state” part of the name gives away, contain no moving parts whatsoever. They store data on tiny stacks of Flash memory cells, similarly to a USB drive — albeit with much...
