Pen drive is usually smaller in size and capacity about 4,8,16,32,64 GB. But hard disk is usually starts at 128 GB and go till 4 TB and is larger in size. Hard disk is typically used as an portable device for backups, installing operating systems and as such. ... There is Platter in Hard Disk (Magnetic Platter).

Used for transport as well as backup and additional storage, portable hard drives rival the capacity of many internal hard drives. Unlike external drives for stationary desktop use that require power from the wall, a portable hard drive is powered from the USB connection. See USB drive kit and SATA.

Therefore, disk space refers to how much space you have available on your hard disk for storing files. When you save a document or install a new program, it gets stored on your hard disk. ... Memory, on the other hand, is not the same as disk space! Memory refers to the random access memory (RAM) inside your computer.

Memory can be roughly divided into flash and hard disk. While hard disk utilises spinning platters that take a magnetic imprint of the data saved, flash memory is a solid-state memory chip with no moving parts. ... Performance-wise, hard-disk drives also tend to give greater read/write times.

Difference between RAM and HDD. ... RAM is used to store computer programs and data that CPU needs in real time. RAM data is volatile and is erased once computer is switched off. HDD, hard disk has permanent storage and it is used to store user specific data and operating system files.

Apple's Fusion Drive combines hard disk and SSD storage in a drive that appears to the operating system as a single volume. Hard disks provide a lot of storage for a low cost per gigabyte, but they're relatively slow. SSDs — solid-state drives — are much faster but can cost over 5 times more per gigabyte.

The reason why lies in the way SSDs and NAND Flash storage work. Filling the drive to capacity is one of the things you should never do with a solid-state drive. A nearly full solid-state drive will have much slower write operations, slowing down your computer.

Earlier data storage devices used to mainly be Floppy drives which had a small storage space. However, with the development of computer technology, we today have pen drives, CD/DVD devices and other removable media to store and transfer data. ... They are called secondary storage devices.
