here's the link of my nvme ssd, https://shopee.ph/Crucial-P2-2TB-1TB-M.2-NVMe-SSD-2280-3D-NAND-PCIe-Solid-State-Drive-for-Laptop-Desktop-i.27499410.10746534351?sp_atk=cb2c0059-4495-4521-b775-d0fcf592bf06&xptdk=cb2c0059-4495-4521-b775-d0fcf592bf06

it says that it can go up to 1,800mb/s read time, but why do i have only 450mb/s when i checked on CrystalDiskMark 8

Depends if the SSD is empty or half full / near Full. Like any entry SSD it gets slower the more you fill it.

is 450mb/s write/read speed good?

Which value are you looking at, sequential reads, random reads?

 

If sequential, then no, not particularly good for an NVMe that should reach up to 2400 MB/s in read speed

And do post here the crystaldiskinfo screenshot of it.    
the P2 is slow QLC SSD, but the read speeds should be still above 1500MB/s.

450MB/s sounds like SATA performance

 

Check manual of the MB, see if you plugged into the right slot. Maybe that slot only supports SATA.

 

OTOH, maybe check Crystal disk info. I don't remember for sure. Maybe it shows current transfer mode. Apparently you don't want to see transfer mode SATA or AHCI.

No, the P2 is incapable to even work over SATA lanes. That’s completely wrong.
i asked him for crystaldiskinfo screenshot, to work out something, but no response.

 

he ether testing the wrong SSD, or there something terribly wrong, with the laptop, SSD, or file system.

Why is that important? It shouldn't make a difference to the CrystalDiskMark score.
