How To Speed It Up
Most people buy SSDs for their speed because they are significantly faster than HDDs. When your SSD isn’t transferring and storing data as fast as you’d hoped, it might not be that the drive itself is slow. A problem or an incorrect setting could prevent the drive from using its full potential speed, and you can increase the speed by fixing the issue.
A few likely causes are probably behind the slow performance of your SSD. While there are always niche problems that can be at fault, it’s probably due to one of the following factors.
Storage Full: SSDs are more impacted than HDDs by nearing capacity. As your drive fills up, expect a performance decrease, especially if you need to move files to another drive to maintain at least 30 percent of available storage.
Inappropriate Storage Configuration: Many settings on Windows govern how your hard drives work. If a particular setting isn’t correct, it could impact the drive’s performance. It’s critical to have your options selected for the specific drive you’re using instead of using settings that were better for an old one.
Faulty Hardware: Some issues with your system that aren’t directly related to your SSD and its settings can also slow its performance. Specific hardware problems can prevent the SSD from performing at its swiftest speed.
PC Bottlenecking: You might be experiencing a bottleneck caused by another computer component. In this case, the SSD’s performance is slow because it has to wait on another part to finish its work and move to the next task.
Whatever is slowing your SSD, there’s probably something you can do to improve its performance and enhance your system’s speed.
When your SSD is slow, you’ll notice a few different things.
You want the full potential speed of your SSD and making sure nothing is interfering with it will help you get it.
To discover why your SSD is slow, troubleshoot potential causes of slowdowns and remedy them.
Two utilities that might help you find the cause of your slow SSD are CHKDSK and System File Checker. One looks for problems with your hard drive and attempts to repair them. The other examines your system files to make sure they’re all in place and in good condition.
If either scan found errors, they could be the reason for a slow SSD.
Another thing you can do to make sure there are no problems with your system is to update Windows and run a virus scan. A virus can lurk silently on your computer and cause all kinds of issues – like SSD slowness – without ever letting you know it’s there directly.
Once Windows is fully updated, return to the Settings page to run a virus scan with the built-in Windows antivirus software.
Once you’re sure your system is updated and functioning correctly, there are no viruses, and the drive is error-free, you can explore other avenues to find a solution to the SSD’s slow speed.
The drivers for your SSD should both be updated. Updated drivers can fix problems that cause issues like slower speeds.
If there was an updated driver, the SSD might work faster now.
Picture the tasks your computer does as a river, and each piece of hardware as its own section in the river, one after the other. Where the river is wider, more water can pass through. Where it’s thinner, less water flows. The same principle applies to your PC’s jobs and the hardware you have.
If you have a great hard drive but an older, slower CPU, the CPU might be a narrow part of your computer’s workflow. The drive can only process tasks once the tasks being done by connected hardware are completed. In the case of the SSD, the most likely parts that could bottleneck your system are the CPU and RAM.
Check for the RAM and CPU usage when your drive speed seems low. For example, if it’s lagging in games, do this during a game when you notice the lag.
If either the CPU or the Memory seems to come close to maxing out, they may be the cause of the slowness instead of the SSD. You may have to upgrade your hardware to reduce the bottleneck.
Another common problem that slows down solid-state drives is having too much on them. Keep your SSD below 75 percent capacity by off-loading files that don’t require the speed of the SSD to another storage drive.
If you have too many files, delete them or move them to another drive. You could also utilize online cloud backup if needed.
AHCI mode is the Advanced Host Controller Interface mode, and it’s a newer, faster protocol for SATA configuration than what came before. If your BIOS uses a different protocol, it might explain the slow SSD speeds.
If you’re comfortable opening your computer, check a few things out in case of problems with the drive itself or connected hardware.
Any of these issues may slow down your SSD. If you find problems with it, you may have to replace a cable or use a different port to restore your speed.

Why Is News And Interests Taking Up Memory? How To Fix It
News and Interests taking up gigabytes of Memory (almost all of RAM) is a concerning issue on Windows 10 and 11 systems. It is a result of memory leaks due to a bug in the program’s coding. Therefore, the app continues using up more memory gradually without freeing it.
Whenever this happens, your computer starts slowing down. Your free storage space may also decrease as the program starts hogging large space for the pagefile after using up the RAM.
Since it’s a memory leak issue in a system process, the only way to properly resolve it is by installing system updates that patch the error.
As of September 2023, Microsoft has not released a permanent solution for this problem. However, until it does, there are a few things you can do to fix it temporarily or bypass the issue.
Here are some possible solutions you can apply to resolve the above error:
Microsoft has released a cumulative update KB5010415 for Windows 10 on 15th February 2023. This update also includes a temporary fix for this memory leak issue, so you need to install it as soon as possible.
However, it only works on Windows 10, version 1903, and later. Microsoft has already ceased support for all previous builds. So make sure to install the necessary system updates before installing the cumulative update.
Then, you can download and install the update from Microsoft Update Catalog. It is also possible to check for the cumulative update on your Update Settings and install it. To do so,
You can also upgrade to Windows 11 or clean install it as this issue is not present in the Windows 11 version as of the current date.
If your computer lags a lot and brings any issues while updating, you can end the News and Interests process or disable it altogether and then install the update.
One way you can resolve this issue temporarily is by killing the News and Interests process.
Doing so only temporarily closes it and it will soon start running again. However, it will still take some time to build up its memory usage to a high value. And you can also carry out the other troubleshooting measures in the meantime.
To end News and Interests or Feeds process, you need to use the Task Manager in the following way:
If you don’t use News and Interests altogether, you might as well disable the feature to resolve the error in a more permanent manner. Furthermore, you need to do so anyway if the update KB5010415 didn’t resolve your issue.
You can easily disable this feature on your system from the Taskbar using the steps below:
There are also other ways to disable it, such as using the Local Group Policy Editor and the Registry Editor. To disable it through the Local Group Policy Editor,
In Windows Home editions, you can’t access the Group Policy Editor by default. In such cases, you can use the Registry Editor to perform the same task.
After disabling News and Interests, you may also have to end its task from the Taskbar if it’s still leaking the memory.

How does Ultra-Wideband technology work?
UWB is quite different from how other wireless data transfers work. It’s a pulse pattern radio-based technology that sends data in the time domain, with a spectrum ranging from 3.1 and 10.6 GHz. Conventional wireless transmissions vary the power, frequency, and/or phase of a sinewave to encode data, rather than simple pulses.
Ultra Wideband Technology Allows for Precise Location TrackingThe biggest benefit of this pulse-based transfer is that it’s possible to calculate time-of-flight information from the received data. UWB can send as many as one billion pulses per second — and each of those pulses can be measured based on how long it takes the data transfer to go from one device to another.
Once you know the time taken for the signal to travel between two UWB devices, as well as the speed of the data transfer, it’s simple math to work out the distance between the transmitter and receiver. In the real world, this means UWB eliminates the risk of relay attacks, commonly employed by car thieves that involves intercepting and rebroadcasting radio signals to maliciously gain access to a locked vehicle.
UWB technology uses time-of-flight to accurately measure distance, enabling applications like secure unlocking.
If you’re thinking that it sounds a bit like sonar, at least on a very broad level, you’re kind of right. UWB technology measures the amount of time it takes for a radio wave to move between two objects, while sonar measures the amount of time it takes a sound wave to travel from its source, bounce off of an object, and return. They’re vastly different in a lot of ways — for one, Sonar doesn’t transmit data — but the basic idea is essentially the same.
UWB uses a wide portion of the spectrum to transfer data quickly…The pulse method also takes up a lot more spectrum to work reliably, which is the reason for the ultra-wideband nomenclature. A single band is typically 500MHz wide, compared to a 5 to 20MHz 4G LTE band or 20MHz to 80MHz for WiFi (see above). Because of the wide spectrum, pulsed data can be sent very quickly without losing accuracy.
UWB can hit data rates from 4Mbps to 675Mbps or more, depending on the frequency. That’s far faster than NFC’s 424Kbps and Bluetooth’s standard 2.1Mbps speeds, but not as quick as the 2Gbps speeds achievable with Wi-Fi 6.
… And it doesn’t interfere with other wireless technology like Wi-Fi or BluetoothTypically, wireless technologies are limited to very narrow bands to avoid interfering with each other. UWB avoids this problem by operating at very low power levels that basically fall within the noise floor of other wireless applications. In other words, the spectrum is so wide that it’s easy to detect but at low enough power that it doesn’t interfere with other signals.
What is UWB used for?
1. Keyless Entry 2. AutomationSelf-driving cars need reliable and ultra-fast sensors to ensure that they aren’t about to accidentally drive full-speed into an abandoned JC Penney. What better technology to help driverless cars “see” what’s around them than UWB, which can emit one billion pulses per second and is accurate to within a few inches?
Like many other industries, UWB has yet to be fully utilized in autonomous cars, but we expect that to change quickly. Ultra-wideband is likely to be used to provide accurate, real-time information, back and forth from one connected car to another, quickly and accurately enough that a world full of driverless cars may actually be possible.
3. Manufacturing and LogisticsIt may not be the sexiest application for UWB technology, but it is one of the most impactful. Because UWB signals are so accurate and reliable, they can be used to track assets in factories, warehouses, and other large industrial sites. Think about it: finding a product in a large warehouse is a lot easier when you can track its location to the centimeter.
Large companies that move hundreds of thousands of items per day (think Amazon, UPS, and others with a high focus on logistics) can benefit greatly from UWB tech. In fact, startups like Kinexon are already providing UWB devices as a solution to enterprise-scale logistics and efficiency problems.
4. Sports 5. Asset TrackingPersonal item trackers like the Apple AirTag use UWB technology to pinpoint the exact location of an item. Boeing also uses UWB technology to keep track of thousands of expensive tools, parts, and equipment in its factories.
These are examples of asset tracking. Using wireless tracking technology can help ensure nothing valuable goes missing again. Lost inventory and supplies are expenses that really add up, and companies like Boeing have realized that they can use UWB tracking to cut down on this.
5. Smart HomesWe love smart homes here at Android Authority, and the potential for UWB in this area is pretty awesome. Just imagine how nice it would be if your home’s lights were triggered automatically every time you walked into a room with your UWB-equipped phone in your pocket. Another cool use for UWB would be the ability to program your front door to unlock automatically when you are within 10 feet of the door — and those are just two of the dozens of ways that ultra-wideband can make smart homes even smarter.
Even better, imagine you lose your phone somewhere in your house. Instead of searching underneath every couch cushion and praying that you didn’t put your phone in the washing machine, you could simply ask Amazon Alexa where your phone is. With UWB, your digital assistant could tell you exactly where your phone was in a fraction of a second!
How is UWB Used in Smartphones?Smartphones that support Ultra-Wideband
Robert Triggs / Android Authority
Even though ultra-wideband technology has been around for a few years, it’s not as commonplace as Wi-Fi or Bluetooth yet. It’s currently reserved for some of the most expensive devices on the market today, simply due to its limited adoption. However, you can expect that to change as the technology makes its way to mainstream vehicles and tracking devices.
The Difference Between UWB, NFC, and Bluetooth Technology
Edgar Cervantes / Android Authority
If the ultra-wideband use cases we’ve discussed so far sound familiar, it’s because many of them can already be done with existing NFC and Bluetooth technologies. Which begs the question, why bother with yet another wireless standard? What does UWB have that other wireless standards do not?
Band and RangeBluetooth operates in the 2.4GHz band, giving it a decent range for indoor use. However, this band is in the same spectrum as some WiFi signals, making it susceptible to interference. UWB’s wide spectrum is much less prone to interference, hence its early adoption in industrial applications. That said, its range is not as long as Bluetooth’s.
UWB offers greater positional accuracy than Bluetooth and NFC, but isn’t as affordable or commonplace yet.
NFC operates at 13.56MHz and most implementations require close physical proximity for data transfer. This means UWB’s transmission distance lies somewhere between that of Bluetooth and NFC. If you need long-range applications, look to GPS or Bluetooth. Short-distance applications are better served by UWB and NFC.
Cost-effectiveness: UWB isn’t as cheap as Bluetooth or NFC When is UWB the best choice?UWB comes into its own when high-speed data transfers, fast location detection with high accuracy, and/or low risk of interference are the key requirements. As mentioned previously, the technology also works well in scenarios that require additional security, such as wireless vehicle access. Ultimately, ultra-wideband isn’t a direct replacement for any of the wireless technologies already on the market. Instead, it’s a better, more versatile choice for different use cases, even though it’s more expensive and not a “one size fits all” technology.
Are there any drawbacks to UWB?The exceptional thing about ultra-wideband technology is that it doesn’t really have many downsides. It’s energy-efficient, versatile, cost-effective, and virtually immune to attacks and interference. That said, there are a few things about UWB that make some people think twice about its value: privacy concerns and slow adoption.
Unethical Tracking: Can UWB be used to track people without their consent?Just like when people were concerned about stalkers using Tile, AirTags, and Galaxy SmartTag devices, there are people who have legitimate concerns about the unethical use of UWB tracking. While there are currently no examples of this tech being used to track people against their will, it’s not hard to imagine that somebody would want to try.
Stalking is the first thing that comes to mind, but there are also concerns about employees (think warehouse employees, retail workers, etc) being relentlessly tracked by management. This type of location tracking breaks several ethical (and potentially legal) barriers, and it’s not hard to envision a near future in which we need strong regulation around UWB technology.
Lack of Adoption: UWB isn’t in enough consumer devices for it to be truly useful… yet.Though UWB is being integrated into more smartphones every year, most of the devices in people’s hands are still not equipped to transmit or receive UWB signals.
