![]() ![]() Like thumb drives, though, SSDs are often much smaller than HDDs and therefore offer manufacturers more flexibility in designing a PC. ( See our deep-dive guide to SSD jargon.) SSDs are consequently more expensive than USB thumb drives of the same capacities. These flash chips (often dubbed "NAND") are of a different type than the kind used in USB thumb drives, and are typically faster and more reliable. A read/write head on an arm (or a set of them) accesses the data while the platters are spinning.Īn SSD performs the same basic function as a hard drive, but data is instead stored on interconnected flash-memory chips that retain the data even when there's no power flowing through them. ![]() A hard drive is essentially a metal platter with a magnetic coating that stores your data, whether weather reports from the last century, a high-definition copy of the original Star Wars trilogy, or your digital music collection. That is, information on it doesn't "go away" when you turn off the system, unlike data stored in RAM. The traditional spinning hard drive is the basic non-volatile storage on a computer. Best Hosted Endpoint Protection and Security Software.An SSD would not be erased by a strong magnet. HDD - Because a hard drive relies on magnetism to write information to the platter, information could be erased from an HDD using strong magnets.īottom line: SSD wins this category. SSD - An SSD is not affected by magnetism. An SSD generates much less heat than an HDD. HDD - With moving parts comes added heat that can slowly damage electronics over time, so the higher the heat, the greater the potential for wear and damage.īottom line: SSD wins this category. SSD - Because there are no moving parts and the nature of flash memory, the SSD generates less heat, helping to increase its lifespan and reliability. HDD - HDDs are usually 3.5" and 2.5" in size for desktops and laptops, respectively, with no options for anything smaller.īottom line: SSD wins this category. SSD - An SSD is available in 2.5", 1.8", and 1.0", increasing the available space available in all types of computers. HDD - With the spinning platters and moving read/write heads, an HDD can sometimes be one of the loudest components in your computer.īottom line: SSD wins this category. SSD - With no moving parts, SSD generates no noise. HDD - With all of the parts required to spin the platters, the HDD uses more power than an SSD.īottom line: SSD wins this category. SSD - The SSD uses less power than a standard HDD, which means a lower energy bill over time, and for laptops, an increase in battery life. Although there are large SSD solutions, it's easier to find bigger and more affordable HDD. HDD - Several terabyte hard disk drives are available for very reasonable prices.īottom line: HDD wins this category. SSD - Although there are large SSDs, anything over 3 TB is usually outside of most people's price range. With the lack of moving parts, an SSD is more reliable than an HDD. HDD - The HDD has moving parts and magnetic platters, meaning the more use they get, the faster they wear down and fail.īottom line: SSD wins this category. The SSD uses flash memory to store data, which provides better performance and reliability over an HDD. Although SSDs have come down in price, an HDD is always going to be cheaper. HDD - HDD is considerably cheaper than SSD, especially for drives over 1 TB (terabyte).īottom line: HDD wins in this category. Desktop computers with an SSD may also have one or more HDDs for cheaper, secondary storage. SSD - The price of a solid-state drive is higher per MB (megabyte) than an HDD. HDD - A typical HDD takes about 5,000 to 10,000 microseconds to access data.īottom line: SSD wins in this category. This faster access speed means programs can run quickly, which is very significant, especially for programs that access large amounts of data often, like your operating system. SSD - An SSD has access speeds of 35 to 100 microseconds, which is nearly 100 times faster. Then, we suggest purchasing a large HDD (either internal or external) for storing documents, pictures, and music. For most computer users, we recommend using an SSD as the primary drive for your operating system and the programs you access most frequently. However, due to its price per unit of memory, it may not make sense to use SSDs in all instances. As you'll learn by reading the following comparisons, the SSD technology is superior. The SSD (solid-state drive) is another storage solution replacing the hard disk drives. The main draw is the high storage capacity and low cost. The standard HDD (hard disk drive) has been the predominant storage device for computers (both desktops and laptops) for a long time. ![]()
