7 Differences between Hard Disk Drive and Solid State Drive

When it comes to data storage, solid state drive is becoming more popular than the traditional hard disk drive in the current era. But actually both of them have their own pros and cons. This article will compare them in 7 respects.

In the past, the hard disk drive was always the first choice for data storage. But in the recent years, with the appearance and development of solid state drive, more and more people prefer the solid state drive due to various factors. Here we will compare the two kinds of drives from the following 7 perspectives.

Differences between Hard Disk Drive and Solid State Drive

But please note that no matter what data storage device you select, both of them will degrade and fail gradually over time. Hence, a consistent and up-to-date data backup is always more than a matter of necessity. For instance, provided that you pretty cherish your PST data, you should back up PST files from the original drive to another storage device, such that even if the drive breaks down, you can easily recover Outlook PST mail.

1. Components

It is known that the primary difference between hard disk drive and solid state drive must be the imparity of their components. The hard disk drive contains the mechanical moving parts, which will constantly spin up when reading or writing data. But solid state drive doesn’t have that. It is totally made up electronically.

2. Speed

Since that the solid state drive doesn’t need to spin in read/write operations, it has a better performance than the standard hard disk drive in terms of speed, no matter the booting, loading or transferring speed. But to be honest, for common computers, the speed of hard disk drive is totally ample and appropriate.

3. Storage Capacity

From the perspective of storage capacity, hard disk drive will be recommended. It is because that you can procure a hard disk drive with large storage capacity only by little money. By comparison, even though solid state drive can also offer large storage, but it is considerably expensive above 240 GB.

4. Reliability

As mentioned at the beginning, both of the two kinds of drives cannot be immune from failure. So actually their failing rates are very approximate. Do you know the solid state hybrid drive? It is a mix of hard disk drive and solid state drive. Also, it has the improved reliability in that it combines the advantages of the two.

5. Duality

For duality, the solid state drive will win. Depending on the foresaid, solid state drive has no the moving parts, which are vulnerable to malfunction. So unlike the hard disk drive, a solid state drive can be exempt from the moving part damages. But although it is more durable, you should still keep care of it.

6. Power-Efficiency

If you’re choosing whether to use a solid state drive or hard disk drive in your PC, you may take the power efficiency into consideration. As usual, the data storage device won’t make much impact on the battery life on your PC. If you want to specify it, a solid state drive is more power-efficient.

7. Price

The last but not the least comparison must be their prices. As I mentioned in the 5th part, the price of the solid state drive with low storage capacity, ranging from 32 GB to 240 GB, is affordable. But if high-capacity solid state drives will be very expensive. So in light of price, by contrast, hard disk drive will be a better choice.
