USB 4とは何ですか？

USB 4は、USB Type-Cケーブルに収容されている最新の仕様またはバージョンのUSBです。USB 3.2および3.0から引き継ぎ、40 GB / sまたは20GB / sのデータ転送速度を提供します。Thunderbolt 4と同様に、同じType-Cリバーシブルで丸みを帯びたコネクタを使用します。

Thunderbolt 4ケーブルはUSB 4ケーブルとも呼ばれますが、すべてのUSB 4ケーブルがThunderbolt 4認定を受けているわけではないため、その逆は当てはまりません。最新バージョンであるUSB 4は、他のどのバージョンのUSBよりも効率的で高速です。接続されているすべてのモニターまたはディスプレイの帯域幅要件を動的に監視でき、データ転送のために残りの帯域幅を同時に節約できます。以前のバージョンのUSBでは、データと表示のために帯域幅を2つの部分に直接分割していたため、これは不可能でした。

Thunderbolt 4と同様に、USB 4も最大100WのPDをサポートでき、Thunderbolt 3、USB 2.0、USB 3.0、USB 3.1、およびUSB 3.2との下位互換性も提供します。USB 4認定のケーブルには、提供する速度（40 GB / sまたは20GB / s）に応じて、40または20の数字とともにUSBロゴが付いている必要があります。

Are SSDs or HDDs better for gamers?

Image
With the release of the PlayStation 5, SSDs have officially become the new gaming standard. A comparison of PS4 and PS5 load times — one with an HDD, the other an SSD — shows clearly just how much improvement an SSD offers. It’s only a matter of time before any new AAA game will all but require a solid state drive. Nevertheless, if you’re working with a tight budget, getting an HDD is more than sufficient, especially since SSDs mean significant space constraints. And even with an HDD, there’s a lot you can do to improve your computer’s gaming performance. Learn more here https://www.ankmax.com/newsinfo/1632698.html

When do you need SSD alignment in Windows 10/11?

Image
SSD alignment mostly refers to SSD partition 4K alignment because SSD adopt the smallest 4K sector in file system to save data. If the smallest 4K allocation units are not always aligned with the 4K pages in SSD, the performance of SSD could be affected. 4K alignment also is widely used in advanced formatted mechanical hard disk. 4K aligned partition better serves operating systems and offers higher performance. One may need to align Windows 10 after clone. There are some signs that show your SSD alignment not OK. For instance, known small file occupies large disk storage in data partition, or system programs and applications run slowly even if you just upgrade hard drive to SSD. If things continue this way, the number of unnecessary writing operations will increase dramatically, which shortens SSD lifespan eventually. ...

What Does Hard Disk Drive (HDD) Mean?

Image
A hard disk drive (HDD) is a non-volatile computer storage device containing magnetic disks or platters rotating at high speeds. It is a secondary storage device used to store data permanently, random access memory (RAM) being the primary memory device. Non-volatile means data is retained when the computer is turned off. A hard disk drive is also known as a hard drive. Learn more here  https://www.ankmax.com/newsinfo/1632698.html
