FAQs about External SSD Speed Test

Do you need more help regarding an external SSD speed test or want to learn more about it? Below FAQs would be useful for you and cover your queries.

1. What is a good read and write speed for an external SSD?

A good read-write speed of external SSDs relies on different factors and manufacturers. This is just an overview of external SSDs speed: SATA III is 600MB/s, 300MB/s, SATA II 150MB/s in old SATA I (SATA limits). Therefore, an average read speed will be about 500MB/s, and an average write of about 300MB/s at least. However, specific models and different manufactured SSDs have very different average speeds.

2. How to check SSD performance?

You can check your SSD's performance through Windows built-in features like Task Manager and Command Line or through reliable software that can provide real and accurate reports, such as EaseUS Partition Master.

You can check SSD performance through "Command Prompt" for basic results. For example, open "Command Prompt," write this command "winsat disk -ran -write -drive (name)", and your SSD speed will be displayed in the "Command Prompt." 

3. How fast are external SSD drives?

The external SSDs are 20-25 times faster than external drives. Of course, the actual speed depends on different types of SSDs and manufacturers. However, there is no doubt that SSDs are more rapid than HDDs and provide an excellent experience.
