ssd usage pinned at 100 percent with 0.1Mbps/sec

ok let me start from beggining. before upgrading to a ssd i had no problems at all, then i upgraded to m.2 sata 3 ssd ( kingstone brand ) and the problem started. when booting up ( doesn't matter if plugged in or not ) there is a random chance that it does not boot up ( goes to a weird gray screen ) and after multiple hard resets it boots up to windows and there is the second problem, there is chance that pc is not responsive and after trying so hard to open task manager it says disk 100% 0.1Mbps/sec . i have tried multiple windows installs with forcefully not installing new drivers, still the same issue. when it works it works fine.

What is the make and model of the replacement SSD as well as the original. I’m suspecting you are using the wrong SSD.

@siaabd - This system requires a mSATA 3.0 GB/s drive are you sure this is a good drive?

さんによる

@siaabd - The SSD does have the correct key (see the image I posted) but the data rate maybe too quick for your system. There are three SATA I/O speeds 1.5 Gb/s (SATA I) 3.0 Gb/s (SATA II) and 6.0 Gb/s (SATA III).

M.2 SSD's first came out with SATA II for a short window of time and then later jumped to SATA III

HP's spec sheet is a bit confusing HP ProBook 440, 450 G2 Notebook PC Specifications and the Wikipedia listing for HP's laptops only give us a clue of the date of production HP ProBook systems which is listed as 2014. So a SATA III SSD M.2 drive would be too fast for your system.

Ensure you have the correct drivers installed, and make sure the SSD or HDD is defragmented. Check for an remove any viruses, and use some compressed air to clean out the connectors on both the SSD/HDD and the computer.

SSDs don’t need defragmentation!
