The hard disk market has been monopolized by several major storage manufacturers in Japan, Korea and United States. However, domestic storage manufacturers represented by YMTC is catching up. Although SSD from SLC to QLC has much shortcoming in erasure times, improvement in capacity allow QLC SSD to catch up with HDD, perhaps achieving SSD $0.14 per GB.
SSD interface continues to evolve with PCIe scalability better than SATA so than client PCIe SSD is expected to reach a market share of about 50% by 2018. But it’s a question how to save costs to reduce the price. This article mainly suggests that DRAM-Less SSD improves overall performance improvement by introducing HMB.
TLC is a flash memory that can store 3 pieces of information per unit. TLC has the lowest comprehensive performance and the cheapest price but the performance of it can be improved by other methods. It needs 8 kinds of voltage states to save more data.
The article introduce that there is a performance differences of the memory cards at different class or even same class by testing the performance of Class 10 products under USB 2.0 and USB 3.0 interfaces. Different classes are suitable for different consumers. Performance, capacity and price should be considered when choosing them. In addition, UHS-1 products can provide more performance for user...
NVMe, short for Non-Volatile Memory Express, is a protocol that makes solid-state drives (SSDs) run faster, and is gaining popularity among enterprise users. It makes full use of the low latency and parallelism of PCI-E channel, as well as the parallelism of modern processors, platforms and applications. With controllable storage costs, NVMe can greatly improve the read-write performance of SSDs,...
The NVMe standards organization has released the latest NVMe 1.3 standard on May 1, 2017, bringing many new features to the consumers and servers such as device self tests, booting partitions, sanitization, virtualization, directives and streams, and so on.
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.
The way to distinguish the quality of SSD is judging surface logo, datailed information, actual test data and SSD quality.
