SATA SSD

シリアルATA（SATA）テクノロジは、ケーブルサイズ、コスト、パフォーマンス、および機能によって妨げられていた既存のパラレルATAテクノロジの改善として2000年に導入されました。どちらのテクノロジも、今日のソリッドステートドライブ（SSD）よりも大幅に機能が劣るハードディスクドライブ（HDD）には十分でした。SATAベースのSSDの出現は、ATAバスがそのパフォーマンス限界に達したことを示しました。HDDが書き込みパフォーマンスで50〜120 MB / sしか達成できなかった場合、SSDはSATAバスを550 MB / sで飽和させる可能性があります。バスの制限にもかかわらず、レガシーHDDテクノロジーの代わりにSATAベースのSSDを使用すると、システム全体のパフォーマンスが10〜15倍向上するのが一般的です。

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
