As early as before, A-DATA introduced the SX8000 series M.2 SSD, the biggest feature of this hard drive is the use of today's few MLC flash memory chips.
The SX8000 series SSDs are available in 128GB, 256GB, 512GB and 1TB capacities. The main control is the Hui SMI 2260, the memory chip is a 3D MLC flash memory provided by Micron, and the data transmission channel is PCIe 3.0 x4. NVMe1.2 protocol, bandwidth up to 32Gbps.
On January 25, 2018, the foreign media made a complete test on the SX8000 series solid state hard disks. The tested solid state hard disk capacity was 512GB. This test was different from the simple and simple writing in the past. The test was read and written at the same time. By adjusting Read and write ratio to see the speed of SSD in the face of reading and writing at the same time.
The Y axis represents IOPS, the X axis represents read / write occupancy, the leftmost end of the X axis represents 100% read, the rightmost end of the X axis represents 100% write, and the middle area represents read and write, and the lower percentage represents The proportion of read and write.
Tests show that A / S SX8000 512GB SSD has a minimum IOPS performance of around 112K when the read / write ratio is 3: 7, while the maximum IOPS performance is about 167K when the read / write ratio is 99: 1.
In addition, a fever test was also conducted. The tests show that when the temperature of the SSD reaches 66 ° C., the write performance of the SSD begins to decrease from about 1000 MB / s to about 200 MB / s and is written until the temperature is lower than 66 ° C. Speed began to rise, while reading the maximum temperature can only reach 51 ℃, so the actual use will not appear performance degradation.
