Hi:

Yes that drive should work fine.

See chapter 1 of the service manual for the supported drive types...

Thanks for your reply, I have little knowledge of computer so I have a basic question, in Chapter 1 it is written as TLC however on SSD spec it is written as NAND TLC, are the both terms are same or different?

You're very welcome.

NAND is the type of memory chips used for the SSD.

TLC is the faster type of NAND memory.

This is the SATA SSD I recommend for your notebook.  This is the 500 GB model...

They also make a 250 GB model, but it is not that much cheaper...

The above two drives provide the fastest sequential read/write speeds for the price.
