【Haichuan Teahouse】Do you know the types of USB drives? The differences between different types are quite significant
Thread Content
From the structure of a USB drive, it can be seen that the flash memory inside the drive is the actual medium used for storing data. The flash memory used in USB drives available on the market today is similar to that found in solid-state drives.
The main types of flash memory are as follows: SLC (Single-Level Cell), with 1 bit per cell; it offers fast speeds and a long lifespan, but is expensive, with a write cycle life of around 100,000 times. MLC (Multi-Level Cell): 2 bits per cell; moderate speed and lifespan, as well as moderate price; it has a write cycle life of around 3,000–10,000 times. TLC (Triple-Level Cell) has 3 bits per cell; some flash memory manufacturers refer to it as 8LC. It has slow speeds and a short lifespan, but is inexpensive, with a typical write cycle life of around 500–1000 times. The differences between SLC, MLC, and TLC are quite significant; typically, manufacturers do not indicate the type of chip used. Some lower-grade chips are often used to manufacture USB drives. This directly results in varying quality levels among USB drives, as well as different lengths of usable life; some people’s USB drives may remain functional for several years, while others may break after just a few uses.
I’m not that interested; I just know that the storage capacity keeps increasing. Back in the day I had a 128M one, which I used for a long time – it can still hold some text even now
