Ever seen computer specs where it is written 128GB, 256GB or 512GB SSD storage space OR 500GB, 1TB HDD storage space and you wonder what it means?
Solid-state drives (SSD) and hard disk drives (HDD) are the two main storage solutions available for computers and they both have their unique benefits. We are not going to tell you which one to choose but by the time you are through reading this article, you should be clear on your choice.
It isn’t difficult to find HDDs with several terabytes worth of storage and they are getting bigger all the time, without too much of an increase in cost to the consumer. In contrast, SSDs tend to be much smaller and become prohibitively expensive over 2TB.
When it comes to storage space though, hard drives have a distinct advantage and likely will do for the foreseeable future. If you want to store something long-term or store large files and folders, computers with hard drives are the way to go.
If you are likely to drop your laptop or you are very rough with devices, it is advisable to go for laptops with Solid state drives (SSD) as they are more durable. If you accidentally drop a device with a hard disk drive (HDD) storage, consider all your stored data gone.
Generally, SSDs are more expensive than their HDD counterparts. You will find that for instance, a laptop with 128Gb storage spec could more expensive than that with 500GB storage spec. One additional reason why Macs are more expensive is that they always come with the SSD storage. Other brands like HP give storage type and capacity options.
Solid state drives are generally faster than the Solid state drive. When discussing the speed of HDDs and SSDs, what is being referred to is the speed at which they can read and write data.
For HDDs, the speed at which the platters spin helps determine the read/write times. When accessing a file, the “read” part of the read/write head notes the positioning of the magnetic sections as it flies over the spinning platters.
As long as the file being read was written sequentially, the HDD will read it quickly. However, as the disc becomes crowded with data, it’s easy for a file to be written across multiple sections. This is called “fragmenting” and leads files taking longer to read.
With SSDs, fragmentation is not an issue. Files can be written sporadically across the cells — and in fact are designed to do so — with little impact on read/times, as each cell is accessed simultaneously. This easy, simultaneous access to each cell means files are read at incredibly fast speeds — far faster than an HDD can achieve, regardless of fragmentation.
Here, we mean how comfortable is it to use a device with an SSD compared to an HDD. Over time, HDD users have complained about it being noisy. Because the HDD comes with movable parts, you can hear the spinning disc and so can cause some sort of discomfort for some users. This is not the case with the SSD as it has no movable parts so you will always have a quiet device.
