With the rising costs of hard drives, SSDs have become even more popular. Let’s delve into the inner workings of SSDs. What is an SSD? Why should you buy one? What benefits does it offer?
The operating principle of SSDs, which we’ve been hearing about frequently in recent years, is quite different from that of traditional hard drives. In conventional hard drives, data is stored on sectors of spinning platters. These platters are rotated by motors inside the hard drive and are read by a read/write head. In SSDs, however, data is stored on NAND flash chips. The memory chips inside SSDs operate as quickly as the RAM in our computers.
Of course, RAM and flash chips have different operating characteristics. Memory chips are divided into two main categories: volatile SDRAMs, which store data temporarily, and non-volatile flash chips, which can retain data for long periods. The type of chips used in SSDs is, as mentioned above, flash chips. These chips are slower than RAM but can store data for longer periods. Even if the power supply is cut off, the data remains intact. RAM, on the other hand, stores data only while powered. When the power is turned off, the data is erased.
