The difference between industrial-grade solid-state drives and consumer-grade solid-state drives
Solid state drives are divided into industrial grade and consumer grade, and they have different meanings and differences.
1. Industrial grade pays more attention to data integrity, that is, it has strict requirements on data security, and the cost ratio is only 5%.
2. On the contrary, the consumption level pays more attention to cost rather than data integrity, because personal computers have a certain fault tolerance for solid-state drives, and price is the key reason for dominating the market.

1.Performance
For industrial-grade SSDs, storage devices must be accessed with minimal latency when dealing with typical data centers processing millions of bytes of random corporate data, including collaboration on CAD technical drawings, analysis of seismic data, or accessing global customer data for banking transactions. Clients that need to access the same data concurrently can be involved without affecting response time.
For consumer SSDs, client applications involving only a single user or application access have a higher tolerance between the minimum and maximum response time for any user or system operation.
Unlike consumer SSDs, industrial-grade SSDs not only optimize the highest performance in the first few seconds of access, but also optimize a larger over-provision (OP), allowing these industrial-grade SSDs to remain stable over the long term.
2.Reliability
NAND flash memory has many inherent problems of its own, including limited life expectancy and natural error rates.
During the NAND flash memory production process, each NAND flash memory particle is tested and characterized by low-level bit error rates.
BER defines the rate of natural bit errors in NAND flash memory, not due to error correction code (ECC). A flash processor's ability to correct these bit errors can be explained by its uncorrectable bit error rate,
Industrial-grade SSDs differ from client SSDs in many ways, including but not limited to industrial-grade SSDs supporting heavier write workloads, more extreme environmental conditions, and higher BER than client SSDs.
Industrial-grade SSDs have only one unfixable bit error per 1 trillion (~1.11PB) processed, while client SSDs have one error per 1000 trillion (~0.11PB) processed.
3.Durability
For each bit of data that is reliably stored for each program or erase (P/E) count of a NAND flash memory cell, the ability of all NAND flash memory contained in a flash memory device decreases until the NAND flash memory can no longer reliably store data. At this point, such flash memory should be removed from the storage pool where the user can find it, and the logical addresses will be moved to new physical addresses in the NAND flash array.
Since client SSDs are typically used only 8 hours per week, industrial-grade SSDs must be able to withstand the heavy write activity of data center servers that require 24 hours of data access per week. Industrial-grade SSDs generally use SLC or E-MLC, and consumer SSDs generally use SLC or E-MLC. Generally, TLC or MLC is used for grade.
