The True Difference between SSD and Flash Storage

The True Difference between SSD and Flash Storage

What Is a SSD?

SSD stands for solid state drive. As a result, it should come as no surprise to learn that an SSD refers to a disk with no moving parts, which is in stark contrast to HDDs. However, it is important to note that while SSDs have come into their own in recent times, SSDs have existed for some time. Due to this, the term can encompass a surprising range of technologies, meaning that not all of the SSDs that have ever existed look like the SSDs that are sold on the open market in the present day.

What Is Flash Storage?

Flash storage is a kind of non-volatile memory, which means that it will continue to exist even when it is not being supplied with power. This is particularly relevant in this context because the earliest SSDs used to have volatile memory, meaning that if they ever lost power, they lost the data that was stored on them as well. Suffice to say that this was a serious problem, thus explaining why it took so long for SSDs to come into their own.

With that said, flash storage had some issues that had to be worked out as well before they could start seeing widespread use. For instance, flash storage used to develop serious problems with repeated use because it could write to memory for no more than a limited number of times. Fortunately, said issue has been made much less serious because of modern advancements.

What Is the Difference Between SSD and Flash Storage?

Modern SSDs use flash storage. However, they are not the sole devices that use flash storage, as shown by the existence of USB sticks. As a result, it is useful to distinguish between SSDs, which are a particular kind of device, and flash storage, which is one of the technologies that make such devices possible.
