This article mainly introduces the difference between pcle solid state disk and ordinary solid state disk in the computer, which has a certain reference value, and interested friends can refer to it. I hope you can learn a lot after reading this article.

Difference: general SSD solid state drives can be divided into four common interface forms: "SATA", "PCIE", "msata" and "M.2", while PCIE is an interface model in SSD. The actual transmission speed of the SATA interface is 560Mbps. The actual transmission speed of the PCI Mure interface is 560MBps.

The difference between pcle solid state disk and SSD solid state disk is reflected in the aspects of transmission speed, interface, performance and so on.

1. Different interfaces

Generally speaking, SSD solid state disk can be divided into four common interface forms: SATA, PCIE, msata and M.2, and PCIE is one of the interface models in SSD.

Second, different transmission speeds

The maximum transmission speed of the PCI-E interface is 16Gbps, and the actual transmission speed is 1560MBps.

The maximum transmission speed of the SATA interface is 8Gbps, and the actual transmission speed is 560MBps.

Third, different performance

The AS SSD performance of the two is different. In terms of continuous read, write and 4K testing, PCI-E SSDs are ahead of SATA SSDs, and the overall score of PCI-E SSDs is more than three times higher than that of SATA SSDs.

Extended data

Classification of solid state drives:

There are two kinds of storage media for solid state hard disk, one is flash memory (FLASH chip) as storage medium, the other is DRAM as storage medium.

1. Flash-based classes: flash-based solid state drives (IDEFLASH DISK, Serial ATA Flash Disk): FLASH chips are used as storage media, which is also commonly known as SSD. Its appearance can be made into a variety of shapes, such as notebook hard disk, micro-hard disk, memory card, U disk and so on.

The biggest advantage of this SSD solid state disk is that it can be moved, and the data protection is not controlled by the power supply, so it can adapt to a variety of environments and is suitable for individual users.

In general, it erases and writes about 3000 times. Take the commonly used 64G as an example, under the balanced writing mechanism of SSD, the total amount of erasable data is 64G X 3000 = 192000g. If you download 100g every day, the available days are 192000 / 3000 = 1920, that is, 1920 / 366 = 5.25 years.

If the average user writes far less than 10 gigabytes of data per day, take 10 gigabytes for 52.5 years, and if you use 128 gigabytes of SSD, you can use it for 104 years without interruption. What's the concept? Like an ordinary hard disk HDD, it can theoretically read and write indefinitely.

2. Based on DRAM class: solid state disk based on DRAM: using DRAM as storage medium, the application range is narrow. Imitating the design of traditional hard disk, it can be set and managed by the file system tools of most operating systems, and provides industry-standard PCI and FC interfaces for connecting hosts or servers.

The application methods can be divided into SSD hard disk and SSD hard disk array. It is a kind of high-performance memory, and its service life is very long. the only disadvantage is that an independent power supply is needed to protect data security. DRAM solid state drives are relatively non-mainstream devices.

Thank you for reading this article carefully. I hope the article "what is the difference between pcle SSDs and ordinary SSDs in computers" shared by the editor will be helpful to you. At the same time, I also hope that you will support us and pay attention to the industry information channels. More related knowledge is waiting for you to learn!
