Shopee has a lot of dubious seller, check for seller rating and dated joined?
share the links to prevent more people fallen into the scam.

ask for technical support from official website, to verify the authenticity of the product, at the same time make complain to shopee.
even a badly configured SSD could not be that slow. the benchmark you posted are same as USB2 thumbdrive.

what is the type of connection you use?

USB2 is the connection, what do you expect? It's not the ssd issue, it's PEBKAC issue.
Even the USB3 is considered slow without UASP enabled.

There are no magic can make it faster, usb2 is the bottleneck.

He cannot understand this question. Stop asking him this already.

there are things that can cause slow performance of ssd, e.g., 4k misalignment due to cloning, bad cable, bad sata port, driver issue, bios misconfiguration, etc.

for now, you can use adata ssd toolbox to check health status of the drive, and run as ssd benchmark to see if the 4k alignment is good.

for rma of the ssd, you might wanna contact adata at fb, https://www.facebook.com/AdataMalaysia/ to get more information about the process.
