What does "write secret hard disk" mean in Intel SSD?
Let me quote the main part of the article. I can't see the picture. If you want to see the picture, you can only look at the original:
Write-intensive application environment
Common model: Intel SSD DC P3700 series, DWPD= 10(800G).
Virtualization environment has a great impact on the life of SSD. When each user generates a virtual machine, the server will divide the reserved disk space for the users. In addition, some security industries use virtual machines to analyze virus behavior, and frequent snapshot creation and repeated snapshot recovery will also lead to a surge in write volume. In the write-intensive environment, SSD has a high write endurance, and MLC memory cells are usually used, which requires SSD to be able to withstand long-term continuous writing without serious performance degradation.
Read-intensive application environment
Common model: Intel SSD DC S4500 series, DWPD= 1.
The impact of read-intensive application environment on SSD life is far less than that of write-intensive. The front page server of the website calls the relevant page address according to the visitor's click access demand, which is a reading-intensive application environment, as well as querying the database. Solid state drives in read-intensive application environments usually use TLC or even lower storage units. With the help of NAND technology, the capacity and writing endurance have been improved, but the price is very low.
Mixed read-write application environment
Commonly used model: Intel Optane SSD DC P4800X series, DWPD=30(375G).
SSD working in mixed read-write scenario will need to have the following characteristics: stable read-write performance in OLTP environment with multi-user and high concurrent access, and extremely low access delay. Otten products with 3D XPoint technology provide users with extremely high I/O performance while maintaining lower I/O delay and QoS stability than NAND particles. Typical application environments include e-commerce shopping platform, online finance industry and real-time analysis of big data. Alibaba Cloud took the lead in adopting Aoteng technology, and the delay index was significantly improved.
