When buying an SSD, you need to decide on two characteristics: speed and capacity. Many people immediately have the desire to spend a lot of money on the fastest trip, but in reality it is not worth it at all. Howtogeek.com portal speakWhy.
Before worrying about speed, you should consider what type of SSD you will buy. Conventional hard drives store data on rotating magnetic trays and read information mechanically. If we talk about launching and running programs, in terms of performance, any SSD will be better than the default HDD.
SATA SSDs keep the same basic interface but replace the rotating part with flash memory. Their maximum speed is limited to 550 MB/s because they use the ancient SATA interface and AHCI protocol, which was originally created for hard drives – not for flash memory.
NVMe SSD is the best choice today. Drives of this type are built on the PCIe interface, which has significantly higher speeds. Even older PCIe 3.0 drives reach speeds of 3,500 MB/s; New models built on PCIe 5.0 technology are even overclocked to 14,900 MB/s.
While on paper there is a huge gap between 3,500 and 14,900 MB/s, in reality the difference between them is not nearly as noticeable as the difference between HDDs and SSDs in general. The jump from SATA to NVMe SSDs isn't as dramatic but is still solid.
But there are some differences between NVMe SSDs. Although there is a large increase in sequential read speed when overclocking from 3,500 to 14,900 MB/s, it is difficult to feel it in real-world conditions. In fact, SSD speeds suffer from performance degradation, which is very serious. If on an NVMe SSD the conditional game loading screen only lasts a few seconds, switching to a more powerful drive won't be as dramatic. Many benchmarks basically show that SSD speed has almost no effect on gaming performance.
While it's tempting to overpay for drive speed, there are other options worth considering for SSDs. First and most obvious is volume. It's not recommended to use one large SSD to store all the files on your computer; For the price of a 1 TB SSD at 14,900 MB/s, you can typically buy two 4.0 terabyte PCIe drives. And if you don't need two drives there's always the option of getting RAM, although currently due to shortages it's expensive.
