HDD vs SSD (Why do I Need to Switch?)

HDDs are a thing of the past now, they are slow and not up to the mark. SSD is the new thing, it has got speed and beastly performance. But at the same time, an SSD is much more expensive compared to an HDD. For this, you have think if you really need an SSD or not. We have put together a number of difference based on which you would be able to decide if you want to upgrade your laptop or not.

What is an HDD?

On the off chance that you have a desktop PC it will no doubt have a customary hard circle drive, on which the working framework, alongside any applications you introduce, and your records and envelopes, are put away.

A customary hard drive contains a round circle – known as a platter – that stores your information. The circle turns, permitting the read-compose arm to peruse information on the plate (or compose information to it) as it passes.

The quicker the platter turns, the quicker the hard drive works, which can affect how rapidly your working framework reacts, and to what extent it takes applications introduced on the drive to load and open.

More seasoned hard drives use an IDE port to associate with the motherboard of a PC, however most present day hard drives use a SATA association. The latest rendition of SATA, SATA III, is found on current motherboards, and empowers the quickest potential information moves for a HDD.

What is an SSD?

A strong state drive (SSD) is more up to date stockpiling innovation, yet it’s still been around for some time now, and on the off chance that you have a cutting edge PC, all things considered, it utilizes a SSD.

As the name proposes, a SSD – in contrast to a conventional hard drive – has no moving parts. Rather, it utilizes NAND streak memory. The more NAND (Negative-AND) memory chips a SSD has, the more stockpiling limit it has. Present day innovation permits SSDs to have more NAND chips than any time in recent memory, which implies SSDs can have limits like HDDs.

Numerous SSDs accompany SATA III ports, which implies they can be effectively introduced instead of a HDD, and numerous likewise come in the 2.5-inch position that littler hard drives additionally come in. In any case, the most extreme information throughput of SATA III is 600MB/s, and keeping in mind that this is fine for HDDs, SDDs are prepared to do a lot quicker speeds, which implies in the event that you have a SSD with a SATA III association, the drive’s presentation is really being kept down by its SATA association.


At the point when you’re picking between a SSD and HDD, the principal huge contrast you’ll see from the start is the cost. SSDs are ordinarily more costly per gigabyte than conventional hard drives.

In any case, it’s important that some SSDs are more costly than others. More established SATA III SSDs are less expensive than M2 and PCIe SSDs, and in light of the fact that the innovation has been around for some time, certain SATA III SSDs aren’t too more costly than a customary hard drive.

On the off chance that you need the most limit with respect to minimal measure of cash, HDDs are the best approach. Assembling forms for conventional HDDs mean they’re currently generally modest to create, which makes them progressively reasonable.

You can get some huge HDDs at low costs, however in case you’re keeping significant information on the drives, it’s ideal to look at client surveys and reports about their unwavering quality.


Firmly attached to the cost when looking at SSDs and HDDs is the limits of the drives. By and large, in case you’re after a great deal of extra room, HDD is the best approach.

HDD limits go from 40GB up to 12TB for business hard drives, while there are much bigger capacities with regards to big business use. Nowadays you can get a 2TB hard drive at a moderate cost, which offers you a lot of room. HDDs around the 8TB to 12TB size are principally utilized for servers and NAS gadgets, where you need a great deal of room for holding reinforcements.

By and large, we’d suggest having a few littler hard drives instead of a solitary huge hard drive. This is provided that the drive comes up short, you may lose every one of your information – if your information is held over a few drives, in the event that one drive comes up short, you won’t lose everything.

In this way, HDDs are useful for putting away heaps of enormous records, which makes them useful for holding photographs, recordings and games.

In the past SSDs for the most part weren’t able to do such enormous limits, however because of advances in innovation you would now be able to get SSDs with terabytes of capacity. Be that as it may, this comes at a higher cost than normal, and huge SDDs frequently accompany restrictively significant expense labels.

On the off chance that you can, it’s a smart thought to go for a littler SSD, possibly around 160GB–256GB, to hold projects, for example, your working framework, for which you need to exploit the SSD’s higher speed, and afterward utilize a HDD to store different documents where speed isn’t as significant.


There are different things you ought to think about when considering whether to purchase a SSD or HDD. For instance, in light of the fact that SSDs don’t have any moving parts they’re increasingly strong, which settles on them a superior decision for PCs and other cell phones.

A SSD can likewise utilize less power than a HDD, which implies workstations may profit by longer battery lives when utilizing a SSD – despite the fact that this will rely upon the sort of SSD you use, and what you use it for.

So is a SSD or a HDD best for you? While SSDs are quicker, increasingly hearty and more power-effective, HDDs are progressively moderate – particularly with regards to bigger limits.

As we referenced before, on the off chance that you have the alternative, at that point it might merit getting a littler SSD for your working framework and applications, alongside a HDD to store your records. There are additionally half breed drives, known as SSHDs, which offer the best of the two universes, with the velocities of SSDs and the limits of HDDs in a solitary drive, and which merit considering in the event that you don’t have the space in your gadget for various hard drives.
