When building enterprise database architectures in the era of big data, the ratio of SSD and HDD storage will vary based on specific business needs and performance requirements.

For example, in terms of storage proportion, HDD may account for more than 90% of the storage capacity in some projects, because the storage system is generally equipped with automatic layering function, SSD is mainly used to store hot data, and non-hot data will automatically settle into HDD.

In terms of performance comparison, SSDS have higher I/O speed, access time, and reliability than HDDS, especially in scenarios with high concurrency and frequent random reads. The read and write speed of SSDS is much higher than that of HDDS, and the read and write speed of SSDS on the market is generally above 300MB/s, while the read and write speed of HDDS is generally in the range of 60-190MB/s. Therefore, using SSDS can significantly improve database performance than using HDDS.

In scenarios with high performance requirements, SSDS as the primary storage media can significantly improve database performance, while HDDS are mainly used for data backup. With the development of technology, AFA is a full flash storage growth rate. In the research report on the next generation of data storage technology, it is pointed out that the proportion of full flash storage and mixed flash storage in the storage market is close to 50%, which further explains the importance and popularity of SSD storage market.

In terms of reliability, SSDS without mechanical components will be more resistant to vibration and shock, so reliability is also higher. In the big data environment, data security and stability can be better protected.

In terms of access time, the access time of SSD is very short, generally around 0.1ms, while the access time of HDD is between 5-10ms, which is very important for big data applications that require fast response.

In practical applications, for example, when an e-commerce platform migrates the database storage media from HDD to SSD, it can be clearly found that the response time of the database is reduced by 50% on average, the write speed is increased by 60%, and the overall performance is significantly improved.

From the point of view of service life, SSD write times are limited, generally determined by the number of erase NAND flash memory. However, modern high-quality SSDS use NAND flash from MLC or TLC, providing up to thousands of erase cycles, while the life of HDDS is generally affected by a variety of factors, including the use environment, read and write frequency, and spikes related to disk wear. Solid state drives can generally be used for 5-10 years, there are about 15 years, about 30,000 hours, and the SSD life is related to the flash type write amount, 128G solid state disk, can write about 300T, write 40G a day, can be used for 20 years.

In terms of data retention ability, HDD is more stable in long-term storage of data, while SSD may face the test of data retention time in the inactive state.

Damage risk and performance. HDD may completely fail after damage, and data recovery is difficult, SSD performance will be reduced near the end of life, but data recovery is easy.

To sum up, SSDS perform better in terms of shock resistance, power consumption and heating, and modern SSD designs also greatly improve the service life. Although HDDS contain mechanical components, proper use can also provide reliable stability. Both SSDS and HHD have a long service life, and SSDS are more durable in some ways. Future use of enterprise data architecture storage is likely to favor SSDS.
