・1. Difference between HDDs and SSDs
Do you know how they are different? Some people may not know it and cannot decide which one they should buy. Let’s learn how they are different so that you can choose your best device easily.

・1-1. Speed
You must have felt frustrated once because your file doesn’t open so long or you need to wait so long time to save your data. Then, you must want to know “Which is faster, HDDs or SSDs?”
An HDD and an SSD are a storage space in a PC. There are data files and applications. When you use a PC, these HDD and SSD access the internal storage space and perform operations. Originally, this mechanism of data writing and access processing greatly differs between an HDD and an SSD. Unlike and HDD, an SSD does not have mechanical parts like a disk (platter) or needle (head). It writes data on a black plate, called a flash memory by passing electricity in an instant. Consequently, an SSD is faster than an HDD. Though how faster depends on the performance of each HDD/SSD, you may feel like 20% to 30%, or even 50% of processing time is decreased, in some case.

・1-2. Price
Prices of HDDs basically depends on their performance and capacity. As mentioned above, since an SSD is superior in speed, an SSD is more expensive than an HDD when compared with the same capacity. In addition, even among SSDs, SLC, MLC, and TLC have different performance and their prices are different. The same is true for durability.

・1-3. Weight
Compared with an HDD and an SSD, an SSD is little lighter. Although, you may not realize it becomes lighter after exchanging an HDD with SSD because it is just a slight difference. Nevertheless, light weight is an important point as well when choosing an external HDD/SSD to carry around. An SSD will be more stress-free to use though the price will be expensive.
From the above content, you would think an SSD is better than an HDD. Besides the above, in terms of quietness, an SSD is superior to an HDD. However, if you want to focus on capacity anyway, HDD is definitely better to choose.

・2. How to choose HDD/SSD: 3 comparison points
When choosing an HDD/SSD, compare following three points.

・2-1. Data capacity
Data capacity is a guide for how much data and applications can be stored on an HDD or an SSD. If you want to store a lot of videos and photos, or if you want to handle various data files for your work, you had better select the one with large capacity. Since an external HDD/SSD are also available, if you later want to increase the data capacity or take out old data from your PC, you can consider such external HDD/SSD.

・2-3. Type
In addition to an internal HDDs and SSDs built in a PC, there are several types of HDD/SSDs, like stationary type, portable type, and NAS. As the name suggest, the stationary type is used by placing it near a PC. The Portable type is compact and lightweight, and it is designed for carrying out. On the other hand, NAS, which is abbreviation for Network Attached Storage, is used for network connection. The stationary type and portable type are basically connected to one PC by a USB cable, while NAS can be connected from multiple PCs via a network.

・Summary
As for an HDD/SSD, the higher the price, the higher the performance. The important things when choosing an HDD/SSD is to clarify for what and how you want to use it at first. Then let’s consider an HDD/SSD with suitable performance.
