SSD storage devices vary in their properties according to the number of bits stored in each cell, with single-bit cells ("Single Level Cells" or "SLC") being generally the most reliable, durable, fast, and expensive type, compared with 2- and 3-bit cells ("Multi-Level Cells/MLC" and "Triple-Level Cells/TLC"), and finally quad-bit cells ("QLC") being used for consumer devices that do not require such extreme properties and are the cheapest per Gigabyte of the four. As of 2019, cells can contain between 1 and 4 bits of data.
Ĭompared with electromechanical drives, SSDs are typically more resistant to physical shock, run silently, and have quicker access time and lower latency.
It is also sometimes called a solid-state device or a solid-state disk, even though SSDs lack the physical spinning disks and movable read–write heads used in hard disk drives (HDDs) and floppy disks. There are several tools and tricks that you can use to make sure that the OS runs efficiently and without filling your SSD (or indeed any other small storage device).An mSATA SSD with the label removed to show the chipset and NAND.Ī solid-state drive ( SSD) is a solid-state storage device that uses integrated circuit assemblies to store data persistently, typically using flash memory, and functioning as secondary storage in the hierarchy of computer storage. How big is your hard disk drive? 80 GB? 300 GB? 5 TB? You might well have more than enough space, but if you own a device with a small SSD – perhaps a netbook, for instance – there is very little to worry about.
This makes it very easy to reinstall Windows if necessary. Indeed, it is possible to install and run Windows 7 on a drive as small as 8 GB!Īdditionally, I’m a big believer in keeping my vital personal data on a separate drive to my Windows system device as much as possible. Of course, this brings us to an obvious problem – is there enough space on a 30 GB drive to successfully run Windows 7? More than enough, as it turns out. However I wasn’t entirely certain about bringing the SSD into my PC, so I opted to spend as little as possible and purchased a 30 GB drive from OCZ. The advantage of a drive that would react quickly to boots and sleep mode without me having to switch the computer on several minutes in advance was obvious. The reasoning was sound – my old main HDD was getting old and slow and I wanted to start to reduce my electricity bill as much as possible. I’ve recently stepped into the modern age and purchased a SSD device for my main PC.
