Completely Peel What is a Solid State Drive

SSD vs HDD which is better? Before we go into a deeper discussion, let’s get to know the basic knowledge first. The hard drive is a very important component in the computer, without this component, the computer cannot store any data. HDD is a hard drive that is widely used in almost every computer in the world. But now there is a new hard drive besides HDD, namely Solid State Drive (SSD).

SSD or Solid State Drive is a data storage medium (non-volatile memory) that uses a memory board as a medium and does not use a compact disk like a conventional HDD so that SSDs do not have mechanical delays in accessing data. Solid State Disks are presented in the operating system in the same way, but have a different working scheme.

SSD is not a new device, you must often see laptops that combine HDD and SSD as storage media. Generally gaming laptops, but there are also regular laptops. And many people are still not familiar with this storage media and consider it the same as HDD. So that you are not as confused as to distinguish SSD from HDD when buying a laptop, let’s get to know Solid State Drives!

SSD vs HDD TRIM function

TRIM is a command that goes directly to the firmware of the Solid State Drive. This function makes SSD performance always fast which is called storage media, if used over time it will definitely be full especially if it is used to write or read data. Therefore, you must immediately delete the data.

On the HDD, data deletion activities are not completely erased, so when new data is written in the same place, it will immediately overwrite the old data. This is called Overwriting. If on HDD this Overwriting activity is common but it is different with SSD, this Overwriting activity will generate garbage (garbage) which causes the SSD to slow down in reading data because it has to sort out old data with new data.

With TRIM, it is certain that if the operating system wants to write new data but in place of the old data, the old data will be erased without residue. In addition to making the deleted place clean, TRIM will also make the Solid State Drive as fast as new.

Contents of Solid State Drive

SSDs don’t have the usual complicated mechanics found in HDDs. For those of you who have seen the contents of RAM (Random Access Memory or computer memory), now the contents of the SSD are similar to the contents of the RAM. A Solid State Drive is simply a collection of memory installed on a board.

SLC and MLC memory

In Solid State Drives, there are two types of memory used, namely SLC and MLC. SLC stands for Single Level Cell whose function is to store a bit of data in a memory cell. While MLC or Multi Level Cell serves to store two bits of data in one cel memory. The SLC type SSD has advantages compared to the MLC type, namely higher data transfer rates, lower power consumption and longer life cycles compared to MLC. Unfortunately, SLC is more expensive than MLC, so it is rarely found in consumer Solid State Drive products.

SSD vs HDD Speed

Solid State Drives don’t have mechanics that have to move while writing and reading data. In addition, the Solid State Drive does not need to rotate the spindle like an HDD. Everything is done electrically. This makes SSDs faster than HDDs.

SSD vs HDD Security

There are some opinions that say that Solid State Drive is more secure than HDD. First, SSDs do not have moving devices in them, making this storage media more secure and durable. Solid State Drives are also vibration resistant because even on HDDs that are not working, noise will definitely be heard because the constant vibration will cause mechanical damage. While the Solid State Drive does not experience it because of the absence of vibration and its non-mechanical form.

SSD vs HDD Price

SSDs tend to be more expensive than HDDs because producing a flash memory requires a lot of money and is also equipped with the latest technology systems. Solid State Drive is a new product that over time, will make the price go down by itself because many Solid State Drives are popping up with more capacities.
