One is the sunset industry, the other is the market star, the mechanical hard disk and the solid state hard disk have a fate of difference between heaven and earth. Nevertheless, the mechanical hard disk based on the Winchester structure is highly complex in terms of dust-free environment during assembly, and the mechanical structure is also very complicated. It requires years of technical accumulation, resulting in the current market capable of making mechanical hard disks. So a few.
The SSD is different. The PCB+NAND+ master routine is nothing more than a technology manufacturer accustomed to the electronic chip industry. It only needs to get the upstream chip channel, plus the rising trend of the SSD. Less brands have entered the SSD market.
SSD cakes are big, but not everyone can eat them. As people become more aware of SSDs and understand the performance and life characteristics of SSDs, the choice of SSD becomes very cautious and rational. But for Xiaobai, so many brands, it is difficult for us to find a good heart. Ok, today we will carry out a teaching of faith recharge and look at the mainstream international SSD brands and representative models on the market. (names not listed in order)
Samsung
When it comes to solid state drives, Samsung is definitely a "old qualification." In the SATA SSD era, Samsung's high-end SSD is a symbol of performance. From 840 to 850, and then from 950 to 960, the Samsung SSD with the PRO suffix has led the performance trend in every update. When we evaluate the new SSD, we always use Samsung's flagship SSD as a comparison. At the same time, Samsung is also the first person to bring the flagship SSD to the terabyte.
In the mainstream and low-end areas, Samsung's EVO series SSD has long occupied the sales champion, and has produced classic products such as 750 EVO. However, Samsung has taken the lead in bringing TLC to SSDs, with 840 EVO and 850 EVO, respectively, which led to extensive discussions on TLC lifetime, performance, and reliability. Until now, TLC has spread all over the SSD market, but this controversy has not stopped.
In 2016, Samsung introduced a new generation of high-performance 960 series, including the 960 PRO and 960 EVO, all supporting the NVMe specification and performance explosion. Among them, the 960 EVO is a "salted fish turned over", and the EVO suffix was first put on the top label.
IntelAlthough Intel has frequently appeared in our field of vision in the PCI-E SSD era, Intel has always been the master in this field with the development of SSD. In the early days of SSD development, the performance of the Intel 320 and 330 series was very good with its own in-chip design, especially in terms of random read and write performance. However, the price has always been very high, so these Intel SSDs once became the darling of high-end users.
Later Intel introduced the 525 and SATA 530 and 535 series for mSATA, of which 530 and 535 performance reached a nominal speed of 540/490MB/s. The subsequent 730 series will increase the performance to 89,000/74,000 IOPS, which has established Intel's position in random read and write performance.
What really makes us look at the Intel SSD side is undoubtedly the Intel 750 series introduced in 2015. More NVMe specification than AHCI, PCI-E 3.0 transmission interface faster than SATA (bidirectional bandwidth up to 8GB/s), plus 1.2TB large capacity, 1.25GB metamorphic cache space, monster performance, one year More, still the king of performance of SSD, no one.
In 2016, Intel launched the new 600p M.2 interface, officially entered the M.2 market, and adopted the Huirong master, officially announced to enter the mainstream market. Of course, these are not all of Intel's ambitions in the SSD market. Optane is the black technology of Intel's heart.
Using 3D Xpoint technology developed at the same time as Magnesium, it is said that the storage speed can be increased by 1000 times (PPT data), and its durability is higher than ordinary flash. The idea is to combine memory and hard drive into one. 3DXPoint Optane non-volatile storage technology combines the high speed of DRAM memory with the data retention of NAND flash memory (in short, there is continuous read and write memory, 4K read and write memory). Speed, there are also SSD power-off data storage capabilities). Although not yet officially put into use, it is enough to shock the entire storage market!
