How Many Terabytes of Mechanical Hard Drives can You Buy for the Price of a Regular Solid-State Drive?

SSD is now widely used. With the price of SSDs dropping, it’s more accessible to buy a SSD to install a system or even store files. The advantages of a mechanical hard drive seem to be only that data is safer and files are less likely to be lost. So I inquired some of hot-selling hard drives to figure out whether the price spread between the two drives was no longer significant.

Mechanical Hard Drives are not Yet Obsolete


As the growing volume of games and files and videos, many people tend to ignore those hard disks less than 1TB when selecting. Now we’re going to find out how many terabytes of mechanical hard drives can you buy for the price of one terabyte of regular solid-state drives?

There are obvious gaps in their prices and performances. In the past, 500GB was the norm for mechanical hard drives, and solid-state drives with a capability around 500GB were exorbitantly expensive, which regarded as a luxury in a computer case. However, 500GB hard drives are hard to find in the market now, and almost all mechanical hard drives from various brands have a capability more than 1TB.

I eventually found the familiar WD Caviar Blue with 500GB, which was 7200 RPM, 3.5 inches in size, and 16MB in cache size. The 500GB Western Digital blue plate served as a main hard drive by people for a long time.

Now the most cost-effective 1TB mechanical hard drive is Toshiba P300 series which own 64MB cache size. If we lower the cache size to 32MB, there are cheaper mechanical hard drives available, but that will also lower the performance and slightly degrade the experience.


SMR is Cheap and Fine


2TB WD Caviar Blue is a bargain for seckilling. Is these makes you feel familiar? This hard drive has a 256MB cache. However, seeing such a large cache capacity, you should be aware of that it is a SMR mechanical hard disk which will be slow when modifying data in large quantities.

As for 3TB hard drive I will also recommend Toshiba, and when it comes to 4TB, Barracuda of Seagate will be your best choice. 

I will skip the rare 5TB, and the price of 6TB mechanical hard disk of major brands are relatively close. You just need to choose your favorite brand when you buy.
We leaped to the 8TB. Generally, the average individual user does not need so much capacity, so 8TB is a grade of the enterprise product. Due to this, 8TB hard drives are relatively expensive and have less species. The 8TB Seagate Galaxy Exos enterprise drive costs $1,549, roughly the price of an advanced 1TB solid-state drive.

As for larger mechanical hard drives, they are no longer available for the price of a 1TB solid-state drive. So for the price of a regular 1TB SSDs, you can buy a mechanical drive with a capacity of roughly 4 to 8 terabytes.
