Storage Devices
Factors that can effect storage devices
speed
capcity
Portability
durability
reliability
Cost
Solid State Drives(SSD)
Solid State Drives are mainly used for holding software
SSD in PCs typically have around 256gb of storage
Hard Disk Drive
Hard Disk Drives are typically used to hold data
the typical storage capacity for a Hard Disk Drive is 1Tb
SSDs are much faster then other storage devices as well as being designed as compact keeping the device small
SSDs are used in most new laptops
SSDs use much less power then a Hard Disk Drive
SSDs consist of a collection of flash memory chips
Magnetic Tape
Magnetic Tape is mostly used for backups and is widely used for archiving data
one chatridge of tape can store 15Tb of data
Magnetic tape can include built in encryption making it very secure
External Hard Drive
External Hard Drives are typically connected to computers through the use of a usb

They can be moved from device to device creating an easy way to move data between devices
They can often be used to save backup data
USB Flash Drive
they typically stores between 16 and 512Gb with some high end ones being able to store 1Tb
Flash drives use very little power, do not include any fragile moving parts and are designed to be small and light
USB Flash Drives are useful when transferring data between computers
SD Card
Some drawbacks are due to their size being easy to misplace
They also have the ability to get a virus from one computer and transfer it to any that it is used on
SD card is a very small form of flash memory card
it can provide high-capacity storage typically between 32gb and 2Tb
designed for smaller devices such as cameras and phones
Optical disks
most often used for storing music/video
Optical disks are widely excepted by systems with most computers being able to read disks
Hard Disk Drives can be considered reliable due to their long life span
They offer Large storage capacity at a relatively low cost
