Why The Hard Disk of windows sometime use at 100 percent and really slow down computer ?

Hello and thank you for your time,
I am having trouble with finding info relative to my specific situation. I own an Asus ROG Strix GL553VD with 16 GB ram and it came with the 1 TB HDD. Ive since upgraded it to a 500 GB SSD by WD Blue as of recetly Ive also added a 120 GB NVMe m.2 SSD and Id really like to be ablr to add my whole windows OS and boot from it to achieve faster results plus Ive heard its less stress on your main drive. I recently tried copying the windows folder to it (and all 26 or so GB that it held) onto the new SSD and that obv didnt work. I have AOMEI partition pro and back upper but my Windows OS isnt on its own partition on C drive and Im finding nothing about migrating just those files or how to create a partition of just those files and I see nothing about migrating from SSD to a different SSD. Thank you for your time and potential help!

I'm thinking about installing "xtra PC" to rev up my Desktop. Does it really work?
If not, does boostspeed have a way of identifying bloatware?
Thank you!

I have a Samsung Portable SSD T5 (1Terabyte) connected to my Lenovo Ideapad PC Laptop (running Windows 10 64bit) via the USB 3 port.
Windows and Samsung SSD software are both up-to-date. When I run the Windows 10 Disc Optimiser it does not detect the Samsung SSD and only shows my harddrive SSD therefore I cannot optimise it using Windows 10. I have tried connecting it to the other USB ports on my PC (these are both USB 2) but the result is the same.
Do you have any idea what can be causing this and is there a solution ?
(My Samsung SSD is detected by BoostSpeed 11 in the "Optimize" section)
I have included a screenshot of the Windows 10 "Optimise Drives" window on my PC if that helps.
Many thanks for your kind attention.

I am trying to do everything right. Vigilance, using auslogics and bitreplica, as well as duplicate file finder, however almost every day, my hardrive fills up, and I can barely get a file to open, due to lack of memory. I have done everything that I know, to try to have all files saved to onedrive, or icloud, but it doesn't seem to make any difference! The computer jams up, because it has reached maximum capacity! Why does this happen, when I am saving files to onedrive (cloud storage). I'm really about ready to chuck this new laptop into the rubbish bin. But.....all available 'new' laptops appear to only have minimal hard drive space. The retailer told me to save my files to the cloud, which is what I am doing, so why does the C drive continually fill up. I move stuff to an external hard drive, in an attempt to free up space, but as soon as bitreplica runs, I'm back to square one. I'm so frustrated, as it takes several minutes just to open a word document. Please please please, can you give me some guidance / direction as to what it is that I am doing wrong. Regards, Kerry

hi there, i am having a issue with my disk usage, my disk usage is at 100% a lot of the time when nothing is showing up in task manager as far as usage, any help on this issue would be greatly appreciated,
kind regards

New for this past week: upon boot up, before opening, screen gives me option of "checking disk" before start up. If I choose not to, I'm to press any keyboard letter within 8 seconds. When I reject option by pressing letter, message disappears and computer opens normally. I've done all the disk checks and cleaning multiple times.
What's this all about?
Thanks, Mark

why hdd is slow

I use a Dell Latitude with an SSD drive. I note that some people recommended that the SSD should not be defragged as it can cause unnecessary wear and tear which will reduce its life span. Every time I run Boot speed it attempts to defrag the SSD. Two questions – (1) Does it really shorten the life of a SSD if it is defragged on a regular basis and (2) If I chose not to defrag how I stop this from happening other than every time manually untick the defrag box prior to hitting the “resolve all” button.
Many thanks in advance for your response.

Hola, ultimamente he notado que mi disco duro se encuentra al 100% y las aplicaciones se abren lento, cuando tenia windows 7 no me pasaba esto supongo que es por el sistema operativo tengo windows 10 pro, ¿habra una solucion para bajar el uso del disco ?

i have tried all the videos in youtube but task manager continuously shows 100% disk
which slows down computer startup increasing boot time
what should i do?

you product wants to defrag and tweak my ssd is this safe?

cuando conecto mi Disco Duro Externo, la pc no la reconoce.
