The USB 3.2 standard is released, which means the transmitting speed can be doubled with existing cables. Using USB 3.2 host to connect with USB 3.2 storage devices could achieve data transmission speed of 2 Gb/sec and realize seamless conversion between single and double channels when operating.
The solid-state disk is a major advance in the history of storage technology. This article briefly introduces the composition, related technology and usage skills of SSD. And the speed of SSD far exceeds hard disk drive, mainly thanks to the internal components: controller, flash memory and firmware algorithm. And it introduces the importance and functions of three components. If users have a bett...
This article is a detailed analysis of SSD Trim. It includes the development history and the cause of its birth. In addition, the appearance of SSD Trim improves the usage efficiency and user experience.
This article illustrates the significance and difference of the latest UHS-III, A2 and LVS standard. Among them, A2 needs memory card to achieve 4000 IOPS random reading speed and 2000 IOPS writing speed, UHS-III supports the speed of 624 MB/s, which aimed at satisfying the demand of SLR cameras and hand-held devices, and LVS standard is for people in low signal voltage circumstances to use.
SD Express extends the capacity of memory card to 128TB, and also brings a transmitting speed of 985MB/s. In addition, it adds PCI Express and NVMe interface, which can support devices of different shapes. The innovation of SD 7.0 standard would satisfy upcoming requirements of applications, which extremely desire for speed and capacity.
This article mainly compare synchronous interface with asynchronous interface. Generally, the asynchronous is faster than the synchronous in transmission rate.In addition, the asynchronous interface has no clock, each data read is triggered by a RE_n signal, and each data write is triggered by a WE_n signal. The difference is that the synchronous interface has a clock signal, data read-write synch...
Flash is inherently not a reliable storage medium due to its limited lifespan. The current controllers combine advanced technologies in wear leveling, power failure management and error correction to enable us to safely and reliably use current high-density flash.
This article mainly introduces the characteristics of different types of memory card and their application.
From 2014 to 2017, the Intel Core processor uses 14nm processes. Moore's Law changes as silicon transistor density from “doubling every year” to “doubling every 18 months” and now faces a severe challenge. Intel’s "Tick-Tock" model is replaced by “PAO” model but the optimization process has run out of time yet. Moore's Law is adjusted according to different periods. The process of printing transis...
The storage of required memory mainly depends on two factors: The equipment and price, 2GB suitable for tablets or entry-level Chromebook laptops; 4GB for entry-level Windows and macOS system devices; 8GB for Mainstream Windows and MacOS device standards; 16GB for professional users and game players; 32GB for enthusiasts and professional workstations.
