How long is the service life of general solid-state hard disk?

There are two kinds of storage media for SSD, one is using FLASH chip as storage media, and the other is using DRAM as storage media.

Based on flash class?

IDEFLASH DISK (serial ATA flash disk): Flash chips are used as storage media, which is also commonly known as SSD. Its appearance can be made into various shapes, such as notebook hard disk, micro hard disk, memory card, U disk and so on. The biggest advantage of this SSD is that it can be moved, data protection is not controlled by power supply, it can adapt to various environments and is suitable for individual users.

Generally, its erasing times are about 3000 times. Take the commonly used 64G as an example. Under the balanced writing mechanism of SSD, the total erasable data is 64X3000 = 192000 g. If you are a perverted video king and like to download videos every day and then delete them every day, then the available days are 192000/. If the daily data written by ordinary users is much lower than 10G, for example, 10G can be used continuously for 52.5 years. If 128G SSD is used, 104 can be used continuously! What is this concept? Like ordinary hard disk HDD, theoretically it can read and write infinitely.

Based on DRAM class?

Solid-state hard disk based on DRAM: As a storage medium, DRAM has a narrow application range. It imitates the design of traditional hard disk, can be set and managed by file system tools of most operating systems, and provides industrial standard PCI and FC interfaces for connecting hosts or servers. The application mode can be divided into SSD hard disk and SSD hard disk array. It is a high-performance memory with long service life. The fly in the ointment is that it needs an independent power supply to protect data security. DramsSSD is a relatively non-mainstream device.
