100 Disk Usage Caused by System and Compressed Memory
System and compressed memory is responsible for the compression of files and folders and the management of RAM. Under normal circumstances, system and compressed memory takes a slight of CPU usage rate. But in some circumstance, system and compressed memory process also arouse the 100 disk usage issue in Windows 10.
This is not alarmist. If you messed up the virtual memory settings like changing the paging file size from Automatic to a set value, the system and compressed memory process starts taking up 100% of the affected disk.
It is entirely possible for Windows 10 users to get affected by this issue. See users' say from answers.microsoft.com:
System and Compressed memory frequently runs at 100% Disk usage for 2 to 3 minutes at a time, effectively preventing any other computer operation from occurring - so the machine just hangs until the disk becomes available again. I'm running an older laptop (Toshiba Satellite Pro) with Windows 10 Pro. I'm not sure if the problem is my laptop is not powerful enough, or if there is something weird happening in the operations.
Right here in this post, you will learn the most effective solution to remove system and compressed memory high disk usage based on Windows 10:
Solution 1. Scan for Virus/Malware
Certain virus and malware can lead to System and Compressed Memory high disk usage. To get rid of this issue, you just need to do the followings:
Step 1: Download and install trustworthy antivirus software.
Step 2: Do a full scan of your computer using the antivirus and clear all the potential threats.
Step 3: Now restart your computer and check the system and compressed memory disk usage.
Solution 2. Repair Corrupt System Files
A system file is any file with the system attribute turned on. Files and folders with system attribute logged on should usually be left alone. To keep operating system running smooth and stable, users should not change, move, or delete these files. For this reason, system files typically are hidden by default and have the read-only attribute.
However, once system files are corrupt, disk usage 100 Windows 10 can emerge. In this case, you need repair corrupted system files by following the steps below:
Step 1: Right-click Windows Start menu, select Command Prompt (Admin).
Step 2: In the pop-up window, allow its changes to your PC.
Step 3: Type sfc /scannow and press the Enter key. It may take several minutes for the command operation to be completed.
Solution 3. Set the Paging File Size back to Automatic
The paging file size for all drives in Windows 10 is, by default, set to allow Windows to automatically manage it. The paging file size can be set to a custom value by the user, but doing can lead to problems with memory compression in Windows 10, ultimately leading to 100 disk usage by the System and compressed memory process. If you customized the paging file size for any of your drives in the past and are suffering from this problem, this solution is the way to go.
Step 1: Open the Start menu, select Settings and then search for performance. Click Adjust the appearance and performance of Windows from the search results.
Step 2: When the Performance Options window pops up, navigate to Advanced and then click on the Change button located under the Virtual memory.
Step 3: The Virtual Memory window will now pop up. In this window, make sure that the box beside Automatically manage paging file size for all drives option is checked, meaning that this option is enabled. Click OK to continue.
Step 4: In the next pop-up window, press OK to allow the restart. Later you are able to see if the system and compressed memory Windows 10 persists taking up high resources.
Solution 4. Disable System and Compressed Memory Process
If Solution 2 did not work for you or if you managed to get to the Virtual Memory window and saw that the Automatically manage paging file size for all drives option was already enabled, the size of the paging files for your drives is most certainly not the culprit. That being the case, you can still fix this problem by simply disabling the System and compressed memory process. To do so, you need to:
Step 1: Right-click the Start menu and choose Control Panel. Then in the Control Panel window, change the view mode to Small icons and choose Administrative Tools.
Step 2: In the next window, choose Task Scheduler.
Step 3: In the Task Scheduler window, follow this path: Task Schedule Library > Microsoft > Windows > MemoryDiagnostic.
Step 4: In the right pane, locate and right-click on RunFullMemoryDiagnosticEntry to choose Disable in the contextual menu.
Step 5: Now restart your computer and check to see if disk usage 100 Windows 10 persists once your computer boots up.
Solution 5. Disable Superfetch Service
Superfetch is a Windows service aiming at improving system performance over time. However, Superfetch can cause the System and compressed memory process to bring 100% disk usage issues. Luckily, you are able to disable the Superfetch service within simple steps.
Step 1: Press Win+R to call out the Run box.
Step 2: Typeservices.mscinto the Run box and press the Enter key.

Solution 7. Kill the Speech Runtime Executable process
Some users found that this system and compressed memory high disk usage is caused by a process named Speech Runtime Executable, which has something to do with audio recording. This process sometimes can use obscenely large amounts of their computers' resources, leading to 100 disk usage further.
If this is your case, you can resolve the issue by simply killing the process. To kill the Speech Runtime Executable process, you need to:
Step 1: Press Ctrl + Shift + Esc to launch Task Manager (or you can right-click on the task bar to load this procedure).
Step 2: In the Processes tab, locate and click on a process named Speech Runtime Executable to select it.
Step 3: Click on the End task button.
However, as the Speech Runtime Executable process is a system process, it can pop up quite often. If doing the above steps does help resolve the 100 disk usage Windows 10 issue, you may have to repeat the process again and again.
Solution 8. Check if RAM Is Failing or Has Failed
In many cases, this system and compressed memory disk usage is caused by failed or failing RAM. To identify, you can replace each stick of RAM one by one and boot the computer again to check. The faulty stick of RAM should be the one without which your PC no longer suffers from system and compressed memory high disk usage.
Kindly remind that if the computer has more than one stick of RAM, only one of the installed sticks may be faulty.
Solution 9. Check for Hard Drive Errors
Also, you may suspect if there are some errors on the hard drive. To do this, you need to use partition magic software to help. Here MiniTool Partition Wizard Free is recommended due to its ease-of-use and free features for disk surface test.

About Disk Performance Test
When computer users get a new hard drive disk, they may want to know the specific performance of the hard drive in their computers. To know the specific performance, they need to do a disk performance test.
Besides, if a hard disk has served for a long time, computer users can also run hard drive performance test in their computers to know whether it still works well, because even the same hard drive has different performance in specified computer conditions.
To understand the result of the disk performance test, I have to introduce Input/Output Per Second (IOPS) and Transfer Rate (also called Throughput).IOPS is the number of I/O operations per second. Throughput is the total data transfer volume per second.
Generally speaking, IOPS can be calculated according to the disk rotational speed. The disk rotational speed will indicate the seek time and rotational delay. The calculation formula is as follows: IOPS = 1000 ms / (seek time + rotational delay time).
The IOPS values of common hard drive have already been listed on Wikipedia. Click here to get them.
However, the calculation result is a theoretical value. The real IOPS of a disk in computer will be affected by many factors. But computer users still can refer to it when they buy a hard drive.
To help you to comprehend the above two indexes, I will show you how to measure disk performance. The Disk Benchmark feature of MiniTool Partition Wizard is recommended. This feature is free for computer users and it displays well the relationship between IOPS and Throughput.
How to Measure Disk Performance
MiniTool Partition Wizard is also an SSD benchmark tool. It can not only complete hard drive test but also carry out SSD speed test.
Here is step-by-step guide to disk benchmark in MiniTool Partition Wizard.
Step 1: Download and launch MiniTool Partition Wizard to get its main interface. And then click Disk Benchmark on the toolbar.
Step 2: Select a drive and set parameters to test the disk performance.
Parameters:
- Select a drive: Computer users select a local disk or a volume to test its performance. The physical disk on where the local disk is located will be listed afterwards.
- Transfer Size: It ranges from 1 KB to 2048 KB.
- Total Length: It ranges from 100 MB to 4096 MB.
- Queue Number: It ranges from 1 to 512.
- Thread Number: It ranges from 1 to 64.
- Test Mode: There are three modes for users to choose: Sequential, Random, and Sequential & Random.
- Cool Down Time: It is used to reduce the hard drive temperature before starting the next test.
When the above parameters are set, the disk benchmark will show you the read and write speed of the hard drive. The result is shown as follows.
Step 3: Click Start after the parameters are set. Then, wait seconds to get a disk performance test result.
How to Set Parameters in Disk Benchmark
The whole operation process is very simple. But what's difficult for common users is to decide the parameter values and interpret the result.
Transfer Size
As we all know, data package will be divided into multiple blocks in input or output transmission process. And then these blocks are transferred. So, computer users can determine the block size in data transmission process by setting transfer size value.
The transfer size will affect the IOPS and Throughput. Generally speaking, there are more IOPS when transfer size is smaller, and there are fewer IOPS if transfer size is larger. Besides, there is a formula about IOPS, Throughput, and transfer size: Throughput = IOPS * Transfer Size.
Generally, bigger IOPS value and big transfer size all can bring in bigger Throughput value to some extent. However, there is an inverse relation between IOPS and transfer size.
For example, as the result picture shows, if the hard drive sequentially reads 200 MB data (total length) with 4 KB transfer size, the disk has a sequential reading speed at 33 MB/S. Then the corresponding sequential read IOPS = 33MB / 4KB.
If calculating IOPS one-by-one, it's found that the IOPS values are about 8000, 7000, 5000, respectively when the transfer size are 4 KB, 8 KB, 16 KB, respectively. However, it is also found that the disk read/write speed (Throughput) is lowest instead when the IOPS value is biggest.
So, computer users should know what value is important.
Actually, when testing the performance of HDD, computer users should pay attention to Throughput value in sequential reading/writing mode with big transfer size. Otherwise, when testing the performance of SSD, computer users should pay attention to IOPS value in random reading/writing mode with small transfer size.
However, due to advanced format technology, 4K alignment can improve disk performance greatly. So, the transfer size value is usually a multiple of 4 KB. So, when running the disk performance test, it is suggested for common computer users to select 4 KB as the minimum value.
Besides, if computer users often run applications with frequent random reading and writing requests like OLTP (Online Transaction Processing), IOPS is an important index. If computer users often run applications with frequent sequential reading and writing requests like VOD (Video On Demand), they should pay more attention to Throughput value.
Then, what's the difference between sequential reading/writing mode and the random reading/writing mode?
Sequential Read/Write Mode
It is usually applied in reading/writing big files. These big files are stored on disk sequentially. And they are also read sequentially by read-write heads. Thus, the seek time and rotational delay time are reduced.
Random Read/Write Mode
It is usually applied in reading/writing small files. These small files are usually stored on disk randomly and discretely. When they are read/written by heads, the seek time and rotational delay time are greatly increased. This performance usually affects computer boot speed, large program booting efficiency, file search efficiency and so on.
Surely, the disk speed test in sequential & random mode is closer to life than other modes. This indicator also should not be ignored.
Thread Number
This value is usually related to CPU. It is related to the kernel number of the computer and Hyper-Threading technology.
Generally speaking, the thread number is determined by the core number. If your computer has two kernels, then the thread number is two. You can check it in your computer. Right click the taskbar, and select Task Manager. Then navigate to Performance to check Cores number.
Tip: In Windows 7, the cores number won't be displayed directly, but you can get it by counting how many CPU graphs are there.
However, Hyper-Threading technology (it is a string of codes) can divide a kernel into two threads. And computer operating system will regard one thread as one kernel. Thus, there are more threads to run more programs. Then you can check the real kernel number and thread number through the following way.
Press 'Windows + R' keys and type 'cmd' to open the command window. Then type 'wmic' and press 'Enter' key. And then type 'cpu get' and press 'Enter' key again. Then you can get the number of cores and number of logical processors (thread).
The hyper-Threading technology can only be applied on Intel CPU. And it can be disabled in BIOS interface.
The thread number can be changed by the following steps. Press 'Windows + R' keys and type 'msconfig'. Navigate to Boot page and click Advanced Options to change the number of processors.

Queue Number
It is the number of I/O requests that are capable of waiting for service in port queue. It touches upon TCQ (Tagged Command Queuing) technology and NCQ (Native Command Queuing) technology. NCQ technology is specially applied in SATA disk. However, TCQ technology is applied more widely.
NCQ and ATA TCQ (PATA, SATA) can support at most 32-class queue length, while SCSI TCQ can support at most 256-class queue length. However, in actual computer operation, the queue length will not exceed 8. (High queue length will increase the I/O response time.)
So, common computer users are suitable to choose a queue length that equals to or is less than 8. Besides, computer users should mainly refer to the disk performance result with queue length that equals to 1. (The commonly defined queue length is 1.)
How to Optimize Disk Performance
Although a hard drive's theoretical performance is defined, computer users can do many things to optimize the disk performance in actual operation. For example, computer users can defrag Windows and set disk cache.
As for disk defragmentation, please click How to Defrag Windows 7 to Improve Computer Performance to get a detailed guide.
As for disk cache, follow the following tutorial to set up. Press 'Windows + R' keys and type 'regedit' to open Registry Editor. Navigate to HKEY_LOCAL_MACHINE > SYSTEM > CurrentControlSet > Control > Session Manager > Memory Management to seek the IoPageLimit value.
Tip: If there is no IoPageLimit value, computer users can create one. Right click Memory Management and choose New > DWORD value. And then type its name as IoPageLimit.
And then, right click IoPageLimit to modify it. Select Decimal and type cache size in KB. 16384 (16 MB) and 32768 (32 MB) are recommended. Then, save the configuration and restart computer.
Surely, there are other methods that can optimize disk performance, please click Free Hard Disk Optimization Software Helps Optimize Disk Performance to know more.
If the disk has very poor performance and computer users can't improve it, they should consider buying a new one.
When computer users buy a new disk online, the disk product names are like the following one.
WD Blue 1TB PC Hard Drive - 7200 RPM Class, SATA 6 Gb/s, 64 MB Cache, 3.5. ---- A disk product name from Amazon
Hard drive vendors know well that their customers usually take disk performance into consideration when buying a hard drive. So, they will post the basic information about their hard drives like the above one.
