SSD stands for Solid State Drive or Solid State disk. This is one storage drive with large capacity, which adopts integrated circuit to load consistent data. The function of SSD is same as hard disk; however, the performance between them is immeasurable difference. SSD basically takes flash memory to store content, the raw material of it is using silicon wafer with ultra high purity; this guarantee the small size and light weight of SSD, also its performance is high efficient and fast. The launch of SSD has fully changed the cognition of storage disk, as it brings one novel, rapid, quiet, large-space and exquisite disk for loading data.
Along with the development of since and technology, people gradually believe in speedy and high-efficient living way. It pushes more and more equipment to choose SSD instead of HDD; the demands of this new storage gadget get zooming. Therefore, the way to order reliable and right SSD is very important. To make good purchase, you have to know more of SSD, especially, the specific parameter, the wafer info and the connection port.
SSD uses NAND flash storage, which is similar to the memory cards. NAND flash is one kind of storage unit consisted of many cells, and the cell will hold the bits; the number of the bits will determine different quality and function of this flash, it is directly associated with the flash memory technology. Whereas, the main difference to distinguish the quality is the flash memory technology they have applied. This technology has been classified by SLC, MLC, TLC and QLC, which is the core parameter to affect the performance of SSD. Let’s start to know these technical indications.
SLC refers to Single Level Cell, it means there is only taking one single cell to store one bit of data. The advantage of this storing way is high stability, fast transmission speed and long lifecycle. As the high performance of this type flash, the cost is extremely high; the capacity of SLC is only available with small ones, it is because of the limit storing space. Therefore, the SSD for home used computers is particularly rare due to the high cost and low capacity. The guides for purchasing the SSD with this NAND flash will be as follows.
MLC stands for multi level cell. There are two bits of data to be stored on each cell, and also can be defined as multi bits of data on one cell. It is easily understandable that the space for storage of this flash is more than SLC; also the cost of manufacturing it is much lower than SLC version. However, lower cost will sacrifice the durability and speed of the SSD. The life circle for SSD in MLC will be around 20,000 to 30,000 times. This version is widely used in consumable market; there is another name for this type SSD – consumer SSDs. Let’s check below notes for ordering this type.
TLC means triple level cell. The flash can store three bits of data on one cell. The only good thing for this flash is cheap, no matter the quality, the speed or the life span are all inferior to the MLC. This is designed for some low-end computer or related devices. The life circle of it is just 3,000 to 5,000 times, which is far shorter than MLC or SLC. The tips for purchasing TLC SSD are as below.
There are four types connection port for SSD, which are SATA, MSATA, M.2 and PCI-E. How important for learning the connection port of SSD? As the connection part is related to the equipment it applied, you need to check this part before the purchase. Also the connection way will highly affect the performance, let’ start to know them.
SATA connection port is the most common one same as HDD, it is very old style; the size of this port is big, but the transferring speed usually gets delayed. Therefore, the SSD with this port cannot exert its speed to the best rate.
This is also one early version used for laptops. However, it is no longer popular in the market now, as it is gradually replaced by M.2 port.
M.2 Port – M.2 ngff SSD
The performance of this port is much stronger than previous ones. The stability and speed is much better with this connection, also the cost of this one is higher. As if the board has M.2 connection female port, then you could consider take this one.
The transmission of this port is super fast as high as 16Gbps, the actual transferring speed is 1560MBps but it is only 560MBps for SATA, also the cost is acceptable.
To order the right SSD, the key information is the flash and the connection port. As if you learn these parameters for SSD, the purchase will be easy and accurate. In fact, clients may focus on more on the life span of SSD as if the cost is similar. MRT accurately has done this selection job for our clients, and recommend the best and suitable SSD for every order. Also we do 10 years and lifetime warranty, it makes sure you no worry of the quality. The only thing you need to do is stay with MRT; all the order of SSD will be successful.
