Answer / Solution
There are several removable secondary storage units commonly used with PCs. Here are some examples:
- Hard Disk Drives (HDDs): HDDs are the traditional and most common form of secondary storage. They use rotating magnetic disks to store data and have high storage capacities.
- Solid State Drives (SSDs): SSDs are becoming increasingly popular due to their faster read/write speeds and improved reliability compared to HDDs. They use flash memory to store data and are available in both internal and external form factors.
- USB Flash Drives: Also known as thumb drives or USB sticks, these portable storage devices connect to a PC through a USB port. They are small, lightweight, and offer a convenient way to transfer data between devices.
- External Hard Drives: These are standalone hard drives that connect to a PC via USB, Thunderbolt, or other interfaces. They provide additional storage space and can be easily connected or disconnected from the computer.
- Network Attached Storage (NAS): NAS devices are connected to a network and provide storage that can be accessed by multiple computers. They often come in the form of dedicated hardware units with multiple hard drive bays.
- SD Cards and Memory Cards: These small, portable storage devices are commonly used in cameras, smartphones, and other devices. PCs typically have SD card slots or USB adapters to read and write data from these cards.
- Optical Discs: While less common these days, optical discs like CDs, DVDs, and Blu-ray discs can still be used for secondary storage. PCs often have optical disc drives that can read and write data to these discs.
It's important to note that the availability of these storage options may vary depending on the specific PC model and its hardware configuration.

Answer / Solution
There are several removable secondary storage units commonly used with PCs. Here are some examples:
Hard Disk Drives (HDD): HDDs are traditional mechanical storage devices that use spinning platters to store data. They offer large storage capacities but are relatively slower compared to other storage options.
Solid State Drives (SSD): SSDs are newer storage devices that use flash memory technology to store data. They are faster, more durable, and consume less power compared to HDDs. SSDs are becoming increasingly popular as primary and secondary storage options.
External Hard Drives: These are portable HDDs or SSDs that connect to a PC via USB or other external interfaces. They provide additional storage space and are convenient for data backup, file transfer, and portability.
USB Flash Drives: Also known as thumb drives or pen drives, USB flash drives are small and portable storage devices that connect to a PC via USB ports. They offer relatively smaller storage capacities but are extremely portable and useful for transferring files between devices.
SD/microSD Cards: These are commonly used in digital cameras, smartphones, and other portable devices. PCs often have built-in SD card slots or require an external card reader to access the data stored on these removable storage devices.
Optical Disc Drives: Although becoming less common in modern PCs, optical disc drives, such as CD/DVD/Blu-ray drives, can be used as removable storage units. They allow you to read and write data on CDs, DVDs, or Blu-ray discs.
It's important to note that the availability of these storage options may vary depending on the specific PC model and its hardware configuration.
