Yes, there is a big benefit for a separate Windows primary partition, and that is the possibility of imaging. After installing a Windows plus adding antivirus plus some basic configuration, I create an image of the entire partition. When I want to have a fresh copy of Windows, instead of installing it, I just restore it from that image. This has the benefit ...

One aspect that wasn't considered so far is: They are not just "hard disks", but also "fixed disks". That means the media (as it cannot be changed) can be extremely clean and of controlled quality, allowing extremely high bit densities through minimum distances between surface and read/write head. Also most current harddisks use multiple ...

The Gigabyte B550M DS3H (rev. 1.x) has the information that was asked: The PCIe 4.0 x16 port can theoretically deliver up to 31.5 GB/s, while the PCIe 3.0 x16 can do up to 15.8 GB/s. You will find below the theoretical limit of all ports together (again, very theoretically): While Gigabyte boasts that theoretically this design delivers up to 64 Gb/s data ...

A Blu-ray laser is rather large, several millimetres, and it's made to fit a slightly unstable optical disc and read it from further away, and the photosensor equipment is also heavy and slow- cumbersome Ti:sapphire lasers to operate in the labs where they are being developed. To get them out of the laboratory and into consumers’ hands, the lasers powering ...

Hard drives don't spin much faster. HDD rotation speeds range from 4,200 rpm (super power friendly) to 10,000 rpm, with 5,400 and 7,200 rpm being the most common. 15,000 rpm server drives used to be on the market, but SSDs made them un-economical to produce so they haven't been manufactured since 2016. A 48x CD-ROM drive spins the disc at 9,600 rpm, a 24x ...

U need a better power supply I had this problem before I am using a 65 watt power supply which is also rated for the computer BUT cpu only reached 46% After using a 90 watt power supply, my cpu can now reach its full potential Its just an easy fix

There are some third-party tools you can use like " Process Hacker ", "Prio" as mentioned in the previous answer. On another hand, If you don't want to use a third-party tool then you have to create a shortcut to that program with a command-line argument "cmd /c Start “” /High “C:\Users\User\Desktop\Program.exe” Program Shortcut ...

In addition to the other answers about why hard disks have better performance than optical disks, another factor (only touched on by @WG481) is that hard disks almost universally have multiple platters that are being accessed at one time, giving parallel read/write opportunities over multiple platter surfaces at the same time. Where an optical disk only has ...

There are two separate questions: latency and throughput. Seek time Optical drives have random seek times around 100 ms, whereas hard drives are around 10 ms - why is this? An optical read/write head consists of a laser, detector, mirrors, lens, and multiple voice coils to position the head/lens for tracking/focusing. This entire assembly has a number of ...

Don't forget, the CD-ROM was an extension of the audio CD. The underlying technology was originally designed with music in mind. It was designed to be fast enough for audio playback, and then later Sony piggybacked the CD-ROM on top of it. This isn't a format designed with high-speed data transfer as the target use case. But why do HDDs spin faster ...

While the other answers are correct, there is more. Optical media is manufactured to be cheap and lightweight. Its just a small piece of plastic. It it not designed to spin at high speeds. The faster it spins, imperfections in the plastic start to cause the plastic to warp. The faster it spins, the more it warps. This warping will make it unreadable by ...

This isn't directly related to the question but it'll help you understand the answers here and why HDD has to be sealed, which is a point repetitively mentioned in the various answers here. First, its worth pointing out how incredibly small the read/write head is. I thought it was big and couldn't understand how it can "crash" to a dust particle. ...

Hard drives are precision assembled in a clean environment and sealed. They can be (and are) made to very high tolerances. CD drives are open and designed to accept media that are clean but may have dust and fingerprints on the surface. These cannot be built to the same tolerances as sealed hard drives. CD drives turn slowly. Hard Drives turn at 7200 rpm (...

Turns out I can still write large files (>100MB) on the stick with no problems at a rate of ca. 10 MB/s (which is somewhat the IO rate I had before, hub doesn't allow for more apparently). Only lots of small files cause performance degradation as lined out in the question, even with relatime mount option.

I had the same issue, and it was iCloud causing the issue, once its removed, all works fine like a charm!

Most of the time I get this question it is a situation where the unit was blazing fast the day of install and over the weeks/months it started to suck big time. This is usually because the person is a super-user that is writing abnormal amounts of data to the drive, causing the drive to work really hard at wear-leveling. It can also happen when the ...

The laptop is defective or infected. For checking infection, run deep antivirus scans by several well-known antivirus products. If no virus is found, the laptop is defective. As it's new, it's not your job to repair it. My advice in this case is to return the laptop and ask to be reimbursed. If refused, ask for a replacement. If also refused, ask for repairs....

Viruses and malware are usually the culprit.. follow these easy steps.. no need to upgrade your pc and spend money. it helped me alot too.. its not just cleaning files but also doing some tweaking in the performance configuration of the windows. You need to delete the bloatware, change the settings of notification, removing unwanted apps and disabling ...

As all the software was updated, and as the laptop is new and its airways do not need cleaning, it's probably working as well as can be expected. The temperature of 55 Celsius is not worrisome at all. Such a low temperature should not even cause any throttling. You should only start getting worried when it nears 90 degrees. Laptops, and especially the modern ...
