how to choose? Advantages and disadvantages of solid state drives and regular hard drives!
Solid-state drives have entered market on a large scale, but traditional mechanical hard drives are still indispensable for conventional installations. Most SSDs come in high performance configurations. Due to small capacity and high price of current SSDs, this leads to few mainstream users of choice at present, but with advancement of technology, there is also a trend for SSDs to gradually become mainstream. Let's take a look at benefits of solid state drives and how solid state drives differ from conventional hard drives.
The advantages of solid state drives over conventional hard drives:
1. The solid state hard drive starts up quickly without motor overdrive.
2. The solid state hard disk does not use a magnetic head, and can be read quickly and randomly, and read latency is extremely low. According to relevant tests, on two computers with same configuration, a laptop equipped with an SSD took a total of 18 seconds from boot to desktop, while a laptop equipped with a traditional hard drive took a total of 31 seconds, almost half that. time between two intervals.
3. Relatively fixed reading time. Since seek time is independent of where data is stored, disk fragmentation does not affect read time.
4. The write speed of DRAM-based SSDs is extremely fast.
5. The solid state drive does not make noise. Since there are no mechanical motors and fans like conventional hard drives, noise level during operation is 0 decibels. Some high-end or high-capacity products have fans, so they may be noisy.
6. Small-capacity flash-based SSDs consume less power and generate less heat during operation, but high-end or high-capacity products consume more power.
7. There are no mechanical moving parts inside Solid State Hard Drive, so there will be no mechanical failure and it is immune to collision, shock and vibration. Therefore, it will not affect normal use even if it is moved at high speed or even accompanied by flipping and tilting, and can minimize possibility of data loss when laptop is accidentally dropped or collided with hard objects.
8. Solid state drives have a wider operating temperature range. A typical hard drive can only operate within a temperature range of 5 to 55 degrees Celsius. Most SSDs can operate at -10 to 70 degrees Celsius, and some industrial grade SSDs can also operate at -40 to 85 degrees Celsius or even a wider temperature range.

9. Small capacity SSDs are smaller and lighter than HDDs of same capacity. But this advantage gradually wanes as power increases. Solid state drives up to 256 GB are still lighter than conventional hard drives of same capacity.
The only downside is that capacity of SSD is too small. Currently, main installation method is to use system drive as an SSD and connect a separate mechanical hard drive for data storage.
