There are three important things to remember.įirst, aside from when an SSD is brand new and contains no data, writing to an SSD is the process of erasing existing information from the flash memory cells and then programming new information onto them.

Writing is totally different and much more complicated with SSDs. The inside of a standard 2.5-inch SSD and a standard 3.5-inch hard drive. In other words, writing to a hard drive is always the same, no matter if the drive currently contains data or not. When you overwrite data (that is, when you write new data to an area that already contains data) the process is the same the sectors just need to be magnetized or demagnetized differently. And the write process is straightforward: the read/write head of the drive hovers on top of the platter and magnetizes and demagnetizes sectors (tiny parts of the platters) into 1 or 0 values to store information in binary patterns. It's coated with a thin layer of metal that can be either magnetized or demagnetized. It's usually made of glass or aluminum and is the portion that stores your information. The platter is the main component of a traditional hard drive. Most of my suggestions will be focused on Windows PCs. In this post, I'll talk about this shortcoming and how to mitigate it. This means you can only write a finite amount of data to an SSD before you can't write anymore. SSDs still fall short in a few places compared to normal hard drives, in particular regarding their write endurance. (Here's some instructions on how to upgrade on a PC and a Mac.) The speed gains you'll experience from upgrading to an SSD will be by far the biggest performance improvement your computer ever has.īut is it all unicorns and lollipops with SSDs? Not quite. If you have an older (or a new budget-class) machine that still runs on a regular hard drive, it's definitely time to upgrade. Most new computers now come with an SSD as the main storage device. However, there is no question that solid-state drives (SSDs) will be the future of storage. Traditional hard drives will be here for long time thanks to their large storage space and affordability.
