Just bought a “new” laptop , and tests on the SSD worries me.

Just bought a “new” laptop which has been remanufactured with parts of recycled PCs. The thing is, I’m new and did some tests on the Drives to check the quality, but I don’t know how to properly interpret the results, contacted the provider and of course he told me it’s okay, but I wanted a second opinion.

My main worry is in some tests the write speed is low while the Read is so high, and its nominal write speed is 1250MB/s.
