With the emergence of newer technologies every year, it has become way too difficult choosing the right computer hardware and the PC storage has been no different. Whenever you buy a new laptop or a desktop computer, a big question always comes to mind is that whether to go with the SSD or the HDD?

Let’s first briefly discuss about the Hard Disk Drive (HDD);It is a traditional storage device that has been used since the dawn of the computer age.The HDD is a non-volatile data storage device which is installed internally inside a PC, attached directly to the disk controller of the computer’s motherboard. It contains platters, housed inside of an air-sealed casing. Data is written to the platters using a magnetic head, which moves rapidly over them as they spin.You must have heard about RPM (Revolutions Per Minute) rate in the specifications of a hard drive.The higher the RPM, the faster the data will be accessed. For example, if you were comparing two hard drives, one with 5400 RPM and another with 7200 RPM, the hard drive with a 7200 RPM will be capable of accessing data much faster than the other.

Keeping that in mind, hard drives are viewed as less durable than the Solid State Drives and that is the essential motivation behind why hard drives are being supplemented by the SSD. Yet, there is a significant interest and demand of Hard Drives around the world because they are cheaper, effectively accessible and have a higher capacity range.

There are a ton of varieties and specs between two, so we have complied advantages and disadvantages of these two competitors.

The key advantages of getting a SSD for your PC

advantages ssd

1. They’re more durable.

With traditional hard drives, the continuous motion generated by small moving parts creates heat, which is a leading factor in hard drive failure. Because SSDs don’t have moving parts, they’re more reliable and more vibration/shock-resistant than traditional hard drives. They’re also more resistant to common drops, accidents, and wear and tear since they don’t have the small, susceptible parts of traditional hard drives. If you happened to drop your laptop and it had an SSD installed, your screen would probably break before the SSD. That’s SSD durability.

2. They’re faster.

Without moving parts to slow your computer down, SSDs aren’t just faster; they’re ready to go when you are. Crucial SSDs offer instant-load performance, meaning faster boot times, faster application loading times, and better system responsiveness.

3. They’re easier to carry.

Since SSDs weigh less than hard drives, they’re more mobile-friendly and they help make your laptop easier to carry. With lightweight components and solid construction, SSDs are better suited for the rigors of constant travel.

4. They’re more efficient.

Since SSDs have no moving parts, they require less power to operate, which means you’ll get longer battery life. They’re even quieter, too.

5. They’re easy to install.

With little more than a screwdriver and your owner’s manual, you can install a Crucial SSD — no experience necessary!

Some users’ reviews for SSD:

Best SSDs

1. Faster everything

“Faster boots and faster program loads compared to a hard drive.” — Hiren P.

Imagine clicking on a program and having it load immediately. That’s the power of an SSD. SSDs also enable “instant on” performance — the ability for your system to boot almost immediately. Since SSDs don’t have to mechanically seek out data on a moving platter (as a hard drive does), they help your system achieve instant-on performance.

2. Seamless multitasking

“Faster backups, faster antivirus full system scans, faster everything!” — Ruben F.

The improved data access capabilities of an SSD allow you to toggle multiple programs with ease. From backing up your data to running antivirus system scans to accessing apps, websites and playlists, an SSD enables you to multitask like a pro — with little to no lag time.

3. Increased energy efficiency

“Lower energy consumption.” — Jason C.

Since SSDs don’t have small moving parts, they require less energy to operate and can increase the life of your laptop’s battery.

4. Better system cooling

“Low temperatures when in use.” — Leon C.

Since SSDs access data using flash memory rather than seeking it out on a spinning platter like a hard drive, they’re able to maintain more consistent operating temperatures, which can help keep overall system temps down.

5. Less fan noise

“No noise, run cooler as no moving parts to generate heat.” — Joe B.

Since SSDs stay cooler than hard drives, your fan doesn’t have to work as hard, which means less fan noise and quieter overall performance. That humming sound you heard when using a hard drive? Gone.

6. Increased durability and reliability

“Higher survival rates after a drop/accident … that alone is priceless. Anyone who has ever had to do data recovery knows what I’m talking about.” — Lisa C.

Since SSDs don’t have small moving parts that are easily susceptible to damage, they can be thrown around and still retain your important files and information. Designed to reliably store your data for years, SSDs offer additional shock and vibration resistance for travel-tested durability.

7 Flexible storage

“You can use them like a flash drive if you have a hot swap bay or dock.” — Nicholaus R.

SSDs are available in multiple form factors, and some form factors (like mSATA) are able to plug directly into your system’s motherboard, allowing the drive to act as a cache drive or to work alongside your existing hard drive. What’s more, with a USB cable, you can use an SSD like a giant flash drive — just plug it in!

8. Better gaming

“Faster load times in games so you are the first to load into a battlefield.” — Travis D.

For gamers, the faster data access speeds of an SSD help enable faster load times, so you can spend more time playing and less time waiting. Many gamers love using SSDs because it means they’re a step (or a load) ahead of the competition, giving them an increased chance at first strikes and a more seamless gaming experience.

9. Easy installation

“Waiting is overrated.” — Marcin M.

With our step-by-step videos and install guides, installing an SSD couldn’t get any easier — no computer skills necessary! Just grab a screwdriver, your system’s owner’s manual, and one of our Easy Install Kits and we’ll walk you through the process.

10. More time for what matters

“To me, it’s pretty simple: the main reason to get an SSD is to save time. Be it booting up, loading applications, general OS responsiveness or intensive operations, a good SSD will save you time so you can focus on what matters.” — Jesse P.

The key disadvantages of getting a HDD for your PC:

1. Far slower to access data than ROM or RAM chips such as SSD:

A PC with an HDD storage will boot up much slower than SSD. depending on their respective RPM or rotation per minute specification. An HDD is prone to fragmentation of data because of its rotary recording surface, it is inherently slower than fragmentation-free SSD.

2. Hard disks is prone to crash leading to loss of data permanently:

3. The disk is fixed inside the computer and cannot easily be transferred to another computer.

4. Durability issue:

One big disadvantage of a hard disk drive is that it is more prone to integrity failure or data loss and data sector corruption. The movable mechanical parts of an HDD make it physically vulnerable to mechanical damages due to drops and shudder. For example, the close spacing between the read head and the metallic platter makes HDD prone to scrapes across the platter as the head grinds the thin magnetic coating.

5. Higher power consumption:

Another disadvantage of a hard disk drive is that it consumes more power than SSD. It needs more power input to rotate the metallic platter and move that magnetic read head. The implication of this is that manufacturers would instead opt for an SSD for computers that are more compact or that have limited battery capacity.

6. Bulkier form factor:

Another disadvantage of a hard disk drive is a bulkier form factor. There is a limit on how small HDDs can be manufactured because of the need for a rotating metallic platter and a moving read head. This makes HDDs not suitable for mobile computing devices such as laptops. Take note that smartphone and table computer manufacturers have been using an SSD storage system.

7. Produces noise while in operation:

The spinning of the metallic platter and the back-and-forth movement of the magnetic read head create mechanical noises while a hard disk drive is in operation. Both spin and movement also create subtle vibrations. This is more noticeable during boot or whenever a user is storing large files. SSD is essentially noise-free.
