Why is SSD more expensive than HDD?

Since the introduction of solid-state drives (SSDs), the amount of excitement surrounding them has been overpowering. Because there are no moving parts, they are far faster than hard disc drives (HDDs), according to media reports. In a way, they are not entirely incorrect.

However, ever since solid-state drives (SSDs) were introduced to the market, people have questioned whether they are worth the high prices they command. More specifically, individuals have inquired as to why these drives are 5-10 times more expensive than hard disc drives in the first place. There are a variety of reasons for this, which I will discuss further below in Why Are Solid-State Drives So Expensive.

They Use a Sophisticated Form of NAND Flash Memory

Flash memory is a technique that is very commonly used. The information is contained in a USB drive, on memory cards for video game systems, and on your smartphone. Flash memory that uses negated AND (NAND) logic gates is unique in that it can sustain storage without requiring continuous electrical power to do so. Due to the fact that SSDs have no leftover energy running through them when your computer is turned down, this is an absolute requirement. NAND has one drawback: it can only be written for a limited amount of time, which means that each transistor will wear out over time.

As a result of the wear and use of your hard drive’s NAND transistors, you may experience everything from minor problems to catastrophic data loss! SSD manufacturers utilise highly advanced techniques to extend the life of their transistors in order to alleviate this problem as much as possible. They will still die at some time, but not as quickly as they have been reported to do in the past. One of their strategies entails including more transistors to compensate for the dead ones that have been discovered so far.

It is difficult for manufacturers to overcome the constraints of NAND transistors, and it is unlikely that they will ever be able to completely eradicate the problem. Writing to a solid-state drive (SSD) will invariably cause it to fail. It’s for this reason that you should only put your operating system and core programmes on it, and save everything else (documents, invoices, images, and so forth) on a separate hard drive.

Device Assembly is Complex

The assembly of a solid-state drive (SSD) is an extremely difficult operation, even without considering the NAND issue. For hours on end, the controller and firmware must both be contained within a tiny space and checked for stability and compatibility with the computers into which they will be placed before being released. This has a substantial impact on the overall cost of production. The manufacturing cost is also the reason why their prices per gigabyte of storage space go increasingly higher as the storage capacity increases. The converse is true for hard disc drives (HDDs), which have a slight difficulty storing additional memory in a short amount of space due to the mechanical operation of the drive.

SSDs Are Lower in Demand

Solid-state drives (SSDs) are becoming increasingly popular, but they still account for a very small portion of the market when compared to hard disc drives (HDDs). As more and more computer manufacturers incorporate solid-state drives (SSDs) as the primary storage device in laptops and desktop computers, the price of SSDs is expected to decline in the future (in fact, the price has already dropped when you compare the price between now and a year back). However, the cost of solid-state drives (SSDs) remains high for the time being. There is, however, some good news. As the number of mobile devices grows, the overall need for solid-state storage will grow as well. This provides a huge incentive for the development of more affordable versions of these technologies.

The Verdict

Prices for solid-state drives (SSDs) are high due to a combination of expensive raw materials, low market demand, and time-consuming production procedures. SSDs, like all devices, are becoming more affordable as time passes, but the battle against rising prices is proving to be quite difficult.
