An HDD’s read/write functionality is based on physical movements. To understand, think about how each hard drive works. So, is an SSD or an HDD more reliable? That’s a bit more ‘apples and oranges’ than you may think. That’s why reliability in your hard drive is so critical. Think about it this way: have you ever worked on a project for days (or even weeks) just to forget to hit “save” at the most crucial moment, losing all that hard work in a single blink of an eye? Imagine that feeling on a much larger scale, with years of information being lost maybe forever. At the top of that list should be hard drive reliability. Wherever you keep your data, you’re going to want a few things. Average speeds for PCIe SSDs range from around 1.2 GB/s up to 1.4 GB/s, and for a significant price, you can get an SSD that reaches 2.2 GB/s. Though you will need to ensure that your motherboard can accept it. You can achieve even greater performance with a PCIe SSD. SATA will get the SDD handling information four to five times faster (read/write speeds of around 550 MB/s) than an HDD. Many SSDs come with SATA III ports and they can be easily installed in place of or in addition to an HDD. SSDs reduce the time it takes to load and write those files. If you're working with high resolution images or 4K videos, do you want to wait for minutes on end for the media to load when you make edits? Of course you don't. Think of this not just in information retrieval, but also in writing. The good news is that PC cases usually have space for more than one drive, allowing you to stack as much storage as you want (for two backups of Game of Thrones? Well, if you must). You can easily acquire one or more HDDs over 1TB in size for a fraction of the cost of their SSD equivalents. Whether you're looking to store years of company information and resources, or you need backups of all eight seasons for Game of Thrones, hard disk drives offer an abundance of storage at a fraction of the cost of solid state drives. The best use for a hard disk drive is mass storage. We'll talk about that more in this article shortly. So, even though your solid state drive is physically more durable than a hard disk drive (shock resistance, can withstand high and low temperatures and submersion in water) it will eventually deteriorate. There's a catch to this: NAND has a finite number of write cycles, leading to performance degradation over time. It does not require power to retain data, instead saving data as blocks and relying on electric circuits to store it. NAND is a type of non-volatile flash memory that reads and writes data to the drive. The more NAND memory chips, the more storage capacity. Instead, solid state drives use Negative-AND (NAND) flash memory. Do you remember using thumb drives or flash drives to store and transfer files? Think of those as your first experiences with a solid state drive.Īs the name suggests, a solid state drive have no moving parts, unlike the "record player" hard disk drive. Though they are considered a newer storage technology, solid state drives (SSDs) have been around for quite some time - you just may not have known it.
