Considerations for Buying an External SSD
Capacity: Determining how much space you need is essential. Options vary from 1TB to 4TB, and it's advisable to opt for more capacity than you think you'll need to avoid running out of space.
Price: Generally, the cost per gigabyte improves as capacity increases, although prices can fluctuate. Compare different models to get the best value.
Speed and USB Interface: All SSDs are significantly faster than mechanical hard drives, but speeds can vary considerably depending on the interface. Models using Thunderbolt or USB4 have higher transfer rates.
Durability and Warranty: Most SSDs are compact and lightweight. Research failure rates and look for models that offer warranties of three to five years for greater peace of mind.
