What’s the performance of a Windows 10 SSD?
Opened task manager (I’m using Windows 10), performance tab and found out that, when it’s about to insert, the SSD is writing only with 200kb/s, whereas l1’s SSD writes with 4.4MB/s. Of course, I took the possibility that the SSD might be defected so I used 3 benchmarks to see.

This person is a verified professional. Verify your account to enable IT peers to see that you are a professional. Step one – rebuild or reorg your indexes. This is usually the most common performance issue with SQL Server and is easy to fix. Change the DB name in the Use line.
What kind of workload does SQL Server have?

What can I do to improve the performance of my database?
Also, make sure your database runs on dedicated hard drives, as this should keep disk fragmentation caused by other processes to a minimum. One number to keep an eye on is disk latency. Depending on hard drive load, disk latency will increase, leading to a decrease in database performance. What can you do about this?
What to do if your database is bad?
If one of your applications or services suffers from bad database performance, do not jump to the conclusion that you know which application or service is responsible for the bad performance. When talking about inferior database performance, you’re really talking about two different things.

Is the disk speed indicative of an overloaded database?
The disk speed would not lead to ORA-3136’s – that is indicative of a swamped machine – or a database that is overloaded. That is, give us a bit more context – I’m still going with “the machine seems overloaded” until you give us some evidence otherwise. Yes Slow to perform DML DDL.
