Disk checker6/21/2023 ![]() Table 1: Types of hard drives in Dell computers The NVMe SSDs use the PCIe bus on the system board. NVMe - NVMe drives, also called M.2 NVMe is a type of form-factor for solid state drives.The M.2 SATA drives use the SATA bus on the system board. M.2 solid state drives are used in certain laptops. M.2 SATA - M.2 also called Next Generation Form Factor (NGFF) is a type of form-factor for solid state drives.SATA SSDs come in 2.5-inch form-factor that can be used in desktops and laptops. Serial-ATA (SATA) SSD - A Serial-ATA solid state drive uses a traditional SATA or SAS interface to connect to the computer.Solid-state drives come in several form factors: Solid-state drives have stronger resistance to physical shock, they run quietly, have faster read/write speeds, and lower latency. Solid-state drives do not have any moving parts, this helps improve the performance of the computer. Solid-state drives use flash memory to store and retrieve digital data. Solid-state drives (SSDs) are the latest type of hard drives that are used on desktops, laptops, tablets, and so on. ![]() A hard drive that is rated at a higher RPM has better read/write speeds compared to lower RPM hard drives. The performance of a mechanical hard drive depends on the revolutions per minute (RPM) rating of the drive. Mechanical hard drives are available in 3.5-inch form-factor that is mostly used in desktops and all-in-one computers and 2.5-inch form-factor that is used in laptops. Mechanical hard drives contain moving components inside the drive. Mechanical hard drives support higher storage capacity, and slower read/write speeds compared to solid state drives (SSD). These drives are electromechanical storage devices that use magnetic storage on a series of physical platters to store and retrieve digital data. Mechanical hard drives (HDDs) are traditional hard drives that are used in most desktops and laptops. Difference between a mechanical hard drive and a solid state drive
