SSD Vs HDD [Which one to Buy in 2021]

Are you planning to purchase a desktop computer or laptop and wondering what configuration you should go with? Allow me to help you out with one feature at least, and that’s the storage part. We will cover all aspects of SSD Vs HDD and will guide you through what to buy when you have choices of 256GB SSD vs 1TB HDD notebook computer.

We’ll also research SSD vs HDD speed tests, gaming functionality, life span. I will also tell you my personal experience of SSD and HDD notebook as I replaced SSD as my notebook’s primary storage.

SSD Vs HDD – what are the Major difference

Here we will compare both kinds of storage drives (SSD and HDD) that are generally utilized to permanently store data on the desktop and the laptops and will find out “SSD vs HDD difference”.

Conventionally these hard disk drives act as a storage solution in desktops and in notebooks. The hard disk commercial usage started way back in 1957 as IBM launched it and was named Random Access Storage. In the initial days of Hard Disk, it used to be 24 inches, but it was reduced to its standard size of 2.5 inches and 3.5 inches with time.

But in recent decades, the SSDs or solid-state drives have gained popularity due to their speed, performance, power consumption, and form element.

Let us know the difference between SSD and HDD in respect to performance and speed, working principle, price and storage capacity, power consumption, durability, cooling effect, and several other elements.

SSD Vs HDD Speed and functionality

Let us start with performance and speed; that’s the principal element when purchasing a laptop or PC for you. let us see where both the storage devices stand when we test speed in SSD vs HDD.

With years the data density of the drive has increased also. But the rate of HDD has not increased at a matching rate.

Paradoxically, the current day hard drive’s access time remains in the variety of a few milliseconds. Along with the successive read or write rate remains around 100 MBPS.

So, you may wonder that is not slow but let me remind you that we aren’t talking about net speed here rather we are considering the read-write speed.

Okay, then allow me to inform you that RAM’s access time and the cache memory used in the laptops and comput0ers are in the range of nanoseconds, which is significantly less than those hard drives’ access time.

Even in case you’ve got an extremely high-end CPU coupled with a graphics card and RAM nevertheless, you won’t be able to extract the best performance from that system if you’re stuck with the slow HDDs.

With top CPUs or GPUs, the operation of your system will undoubtedly increase. Due to the hard disk restriction, the PC boot time and the software’s launching will be delayed.

And in actuality, even it is possible to accomplish the sequential read and write rate in the assortment of Giga Bytes per second using this SSD.

Now let us look into those drives’ inner structure, and let’s find out why SSDs are so quick, and hard disk drives are relatively slow compared to these SSDs.

When you look in the hard disk drive, hard disks are made of a rotating disk called the platers.

So, these platters rotate at the standard rate of 5400 or 7200 RPM on notebooks. And in certain conditions hard disk, the rate can go up to 15000 RPM.

The information is typically saved in this hard disk drive in the kind of tracks and the sectors.

Now, as it entails the moving parts, there’s a limit on the rate at which the information can be obtained or written on those hard disk drives. And to be exact, if I say, they’re designed with the NAND flash memory.

So, besides the flash memory, the SSD also comprises the microcontroller and the little cache memory. And using the cache, it is possible to keep the incoming and the outgoing data temporarily.

SSD Vs HDD Form Factor

Let us compare the two drives concerning the size.

As of now, HDDs can be found in two sizes or form factors. For a desktop, it’s offered in a 3.5-inch size, while for a notebook, it comes in a 2.5-inch.

On the opposite hand,  SSDs can be found in many sizes.

Aside from these, the mSATA and the M.2 SSDs can be found in minimal form factors. And they are used in Ultrabooks and tabs.

You can replace your disk drive of a notebook with an SSD with the help of a 3.5-inch caddy.

The most frequent HDDs storage capacity is 1 TB, which can typically go up to 4 TB. On the other hand, SSDs storage capacity begins from 120 GB and can go up to up to 2 TB.

SSD Vs HDD cost

The 2 TB SSDs are too costly and can go up to 50000 Rupees or $700.

However, if we discuss the price, these SSDs are much more expensive than hard disk drives.

Whereas HDD cost is about 3 to 6 rupees per GB based on brand, quality, and speed. 1TB HDD price generally in India is about Rs 3500 for internal use of notebook or desktop.

As COVID-19 lockdown has gone and markets are returning to their normal business, the SSD rates are also reduced. You can get a 500 GB NVMe SSD at 5200 Rupees in INDIA, which cost you around 9000 Rs previously. Check out the new SSD additions at Amazon. 

Power Consumption and Data Durability

As you know, HDD has rotating components, and your electricity consumption will reduce to nearly 70% when you shift to SSDs from hard drives. In my personal experience, I can tell you that after I installed SSD in my notebook(It had HDD originally for storage and it still has the HDD but as the secondary storage), the backup has gone to 7hrs from nearly 4 hours.

Also, SSD needs less cooling because of no mechanical component, keeping your laptops cooler than HDD.

HDD are more vulnerable to physical damage compared to SSDs since it is made of platters. However, HDD can sustain more information cycles than SSD. The information cycle means the time you upload and erase files or documents to your hard disk.

However, as of today, these SSDs are somewhat more expensive compared to hard disk drives. If somebody is searching for higher storage space, he can choose the hard disk drive which he can find within a reasonable cost.

SSD VS HDD Notebook Performance

This part will compare HDD and SSD in w.r.t my testing on an older laptop. Here is the short story for unfamiliar people: I have an older laptop where I would like to replace some parts such as the keyboard with a touchpad and upgrade the hard drive. There are benefits to both of these options, so I will compare HDD and SSD to determine which would be best.

In testing the two in terms of performance and speed, the conclusion is fairly obvious; the SSD wins by afar. The difference between the two is minimal and insignificant in reality, so all things considered, the SSD win this comparison.

Conclusion of SSD Vs HDD

On the other end, if a person wants rapid performance and is willing to pay extra bucks for that functionality, then should with the SSDs.

My personal opinion will be to have an SSD and HDD both at precisely the same time. While SSD can be your boot drive, in HDD, you can save your all seldom-used data.

Shop your infrequently used data in HDD for more extraordinary performance and battery backup. The less you get those data, the less the HDD will be utilized, which will increase your PC’s performance.

FAQs in SSD Vs HDD

Which is better, a 250gb SSD or a 1TB HDD?

A 250GB SSD and 1TB HDD will cost you almost the same. 1TB HDD will give you more storage space while 250GB SSD will give you less space for storage but will provide you far better speed than HDD.

SSD vs HDD, which one is better?

SSD will give you better speed but will cost you more than HDD for the same storage price.

Would installing an SSD into my computer make it faster?

Yes, installing SSD will make your laptop at least 3 times faster. I have personally experienced it and found my laptop booting speed and operating speed increased by 4 times.

Which is more important RAM or SSD?

SSD is more important than RAM as SSD will make your laptop faster.

Should I get a laptop with 1 TB HDD or 256 GB SSD?

A 256GB SSD laptop will have less storage space but you will have a far better speed.

Why is SSD not a good option for long-term storage?

SSD is more vulnerable as compared to HDD.
