m.2. NVMe, MLC, TBW, ......In the face of many complex specifications of SSD, many friends said that their heads are going to be big, and there is no simple and easy-to-understand way for me to choose an SSD that suits meAs you wish, let's tell you the five common senses you must have when buying an SSD!
SSD has three major components.
Most of the popular SSDs on the market are composed of three major components: the main control chip, the flash memory chip, and the cache.
We can think of the work of the SSD as accessing items in the warehouse, the main controller is the warehouse manager, the data is the items, he manages the items in the warehouse, and is also responsible for controlling the entry and exit of items in the warehouse;Pellets are equivalent to the shelves of a warehouse, which are used to store goods;The cache is a small cart used to carry items, which greatly improves the efficiency of outbound and warehousing.
The quality depends on the particles and the main control.
Among them, as the particles of the shelf, of course, it is necessary to choose a firm and strong one, otherwise it is easy to cause collapse and cause damage to the items. At present, there are four common particles on the market, SLC, MLC and TLC, QLC. The first two are generally used in high-end industrial storage because they are expensive and stable, and TLC particles have become the mainstream choice of consumer-grade SSDs because of their high cost performance.
The main control is the same as the particles, and it is also necessary to identify products with quality assurance, and now the mainstream main control is Samsung, Huirong, Phison, etc.
Third, you must also understand the combination technique.
There are two ways to connect an SSD to the motherboard: SATA and M2 interfaces. The SATA interface is like a small door in a parking lot, and the access is more cramped. m.The 2nd interface is the gate, which is easy to enter and exit.
The bus and protocol of data transmission are equivalent to the road and transportation to the CPU, the SATA bus is narrow, and the speed limit needs to be careful when driving, and the PCI-E road is wide and can be fast-movingThe AHCI protocol is equivalent to a bicycle, and the speed was considerable before, but now it can't be compared to the NVME protocol like a car. So, mThe combination of 2+PCI-E + NVMe is a well-deserved leader in the SSD industry.
Fourth, the capacity is linked to the life of TBW.
According to the formula for calculating TBW (the amount of data that can be written by the SSD) (TBW = capacity * PE number of times write amplification * 1024), it can be seen from the numerator of the formula that the larger the capacity of the SSD, the greater the TBW value, and the theoretical service life is longer. Therefore, when you have a good budget or ** suitable situation, it is more advantageous to buy a high-capacity SSD.
Fifth, the performance depends on the 4K read and write speed.
4K random read and write performance is a key metric for SSDs, which is measured in IOPS, which is the number of reads and writes (IO) operations performed per second. If the 4K read and write speed is fast enough, it can affect the smoothness of daily computer use, improve the speed of game loading, small and small file copying, etc., so the larger the 4K random read and write value, the better the performance.
The latest launch of the Xingyao 7000 Plus SSD uses Phison master control and TLC particles, and is available in PCIe40 and nvme1With the support of the 4 protocol, the sequential read and write speed of the 1TB version is 7000 6000 MB s, and the 4K random read and write speed reaches 1000K 850K IOPSThe 2TB version delivers sequential read and write speeds of 7000 to 6400 MB s, and 4K random read and write speeds of 1000k and 950K IOPS. Whether you're working with large files, editing**, or opening heavy applications, it's up to the task.
At present, the Xingyao 7000 Plus SSD is now available on major e-commerce platforms, and those who need it can go to buy it
