What is SSD?

 

SSD(solid state drive) is the advanced version of HDDs. It is an internal hardware part used for storage purposes. SSDs also contain eproms, which are a kind of memory chip. Thanks to these eproms, data is stored electronically, unlike HDD. It has been used in common during the transition from HDD to SSD, but lately SSD is used more in new devices because SSDs are better in performance. 

There are two types of sides, SDRAM and flash sides. SDRAM ports are located in RAMs and keep data for a short time and data is lost when power is lost, but flash sides keep data for a long time and data is not lost in case of power failure, so there are flash sides in SSD. The data processing speed of SDRAM and flash drives is equal. 

Flash chips in SSD are divided into two as MLC (Multi Level Cell) and SLC (Single Level Cell). SLCs store 1 bit of data per cell and have little capacity but high performance. MLCs, on the other hand, store data over 3 bits and are used in high-capacity SSDs, but have lower performance than SLC.

SSDs are more preferred today because they do not contain mechanical parts, they are faster, quieter, more durable, emit less heat, consume less energy and take up less space. A SATA-connected SSD, which can technically be the lowest speed, is 8-10 times faster than a normal HDD.

Of course, to tell the difference in today's SSDs, m2 Sata or Nvme ssds are more preferred. The reason for this is that there is a huge difference in speed and performance between them.
