What is an External SSD?
An external SSD, also known as a portable SSD or solid state drive, is a type of external storage device that utilizes flash memory to store data. Like an internal SSD that can be installed directly into a computer, an external SSD connects to a computer through a USB port. It provides faster data transfer speeds and better durability compared to a traditional external hard drive.
Some key advantages of using an external SSD include:
- Faster file transfers: External SSDs can achieve data transfer speeds of up to 550 MB/s over a USB 3.0 connection, which is much faster than external hard drives.
- Better durability: External SSDs are less prone to damage if dropped or bumped since they don’t contain moving parts like a traditional hard drive.
- Compact size: External SSDs are much smaller in physical size than portable hard drives.
- Encryption support: Many external SSDs support hardware-based encryption to keep data secure.
Is an External SSD Good for a Desktop PC?
Using an external SSD with a desktop PC can provide several benefits:
Faster Boot and Load Times
Installing the Windows operating system along with apps and games on an external SSD can significantly decrease boot and load times compared to a hard drive. The faster data transfer speeds of the SSD allow the computer to access programs and files more quickly.
Easier Drive Migration
An external SSD makes migrating your operating system, apps, and data to a new PC much simpler. You can connect the portable SSD to your new computer and boot directly from it without having to reinstall everything.
Extra Storage Space
Adding an external SSD provides you with more space to store files, photos, videos, games, and anything else. This is useful if you have limited internal drive capacity on your desktop.
Makes Data Portable
The compact size and plug-and-play functionality of an external SSD makes it easy to transport large amounts of data between different computers. You can bring projects, files and other important data with you wherever you go.
Backup Capabilities
Using cloning software, you can regularly back up the contents of your internal system drive to the external SSD. This provides added data protection in case your main hard drive fails.
Is an External SSD Good for a Laptop PC?
External SSDs provide several advantages when used with a laptop:
Increases Storage Capacity
Laptops generally have limited internal drive space, so adding an external SSD can significantly expand your available storage for storing files, media, and installed software.
Faster File Transfers
The fast transfer speeds of a portable SSD allow you to move files on and off your laptop much quicker compared to traditional hard drives. This improves workflow efficiency.
Enhances Data Protection
Regularly backing up your critical laptop data to an external SSD provides an added layer of protection from system failures or drive corruption. Sensitive business or personal information is better safeguarded.
Adds Flexible Storage
An external SSD gives you flexible extra storage capacity that you can take with you wherever you use your laptop. You don’t have to worry about running out of drive space.
Better Durability
Since external SSDs don’t contain moving parts, they can better withstand being frequently transported in a laptop bag and connected/disconnected from your computer. This makes them ideal for on-the-go laptop use.
What to Look for in an External SSD
Here are some key factors to consider when selecting an external SSD:
Storage Capacity
External SSDs typically offer anywhere from 250GB to 2TB of storage space. Consider how much capacity you’ll require to store your files, apps, photos and other data.
Form Factor
Common external SSD form factors include 2.5-inch notebook drive size as well as smaller more compact units. The right one for you depends on your portability needs.
Interface Type
Most external SSDs connect via USB 3.0, USB 3.1 or USB-C. Faster USB generations offer higher data transfer speeds. Make sure your desktop or laptop supports the interface used.
Read/Write Speeds
Faster SSD read/write speeds allow for quicker file transfers and system boot times. Look for an external SSD with at least 400MB/s read/write speeds over USB 3.0 for optimal performance.
Security Features
Some external SSD models provide password protection and hardware-based 256-bit AES encryption to keep your sensitive data secure across devices.
Ruggedness
External SSDs designed to meet certain drop, shock and vibration tolerance standards offer enhanced protection from damage during transport and use. Consider based on your usage conditions.
Warranty Length
Most quality external SSDs come with a 3 to 5 year limited warranty. Select a model with a warranty that provides adequate coverage for your intended usage scenario.
