SSD vs HDD: Which Is a Better Storage Device

SSD vs HDD: Which Is a Better Storage Device

When it comes to storage devices, there are two main types of contenders: SSDs and HDDs While many gamers and tech-savvy people consider SDD the winner of this race, there is more to it.

In this blog post, we'll compare these two storage devices head-to-head based on speed, price, availability, data recovery, and performance.

What is HDD?

Hard Disk Drive, usually simply called a hard drive or HDD, is a data storage device. It is mainly used in computers and cloud servers to store data. HDDs are subdivided into volume, track, and sector.

The spinning disks store data in tracks that the read/write head can access. When it comes to capacity, the modern hard drive can reach up to 32-64 TB.

What is SSD?

SSD, or Solid-State Drive, is a data storage device that uses integrated circuit assemblies as memory instead of spinning disks. It reads and writes data extremely fast due to the high-speed memory chips and read circuit.

Furthermore, it is more rugged since it has no moving internals and is less likely to be damaged if dropped. However, it is more expensive and has a lower capacity, with the current limit being around 8TB.

Now that we have a basic understanding of the two storage devices, let's compare them in the different aspects of SSD and HDD Difference (Detailed Analysis)

Here we will explore all the differences between SSD and HDD in terms of speed, reliability, price, durability, and other major criteria. You can set your preferences and make your decision if SSD is better than HDD for your needs.

SSD vs HDD Speed

HDD is slower than SSD since it must wait for the disk to spin around to the correct location before it can start reading or writing data. Furthermore, it must move the read/write head back and forth to access different tracks.

On the other hand, SSD can start reading and writing data immediately since it doesn't have to wait for the disk to spin.

Typically, HDD has a top read/write speed ranging from 80MBps to 160 MBps. Meanwhile, SSD can have a reading/writing speed of 350MBps to 550MBps.

Verdict: SSD is a clear choice for people looking for high speed. Most gamers, crypto-miners, and other professionals who need high-speed read/write should go for SSD

HDD vs SSD Price Difference

HDD is cheaper than SSD because it is the older technology and has been around for much longer.   A 1 TB Hard disk drive is priced at around $44 while a 1 TB solid state drive costs around $90.

Which one is Cheaper: HDD is a better option if you need large storage capacity on a budget. However, the SSD price is dropping and is expected to be lower in the coming years.

Reliability and Durability Difference between SSD and Hard Disk

Since SSD has no moving internals, it is more rugged and less likely to be damaged if dropped. On the other hand, HDD is more fragile since it has spinning disks. SSDs are also more resistant to heat, moisture, and magnetic fields.

Besides, Hard drives are 5-8 folds heavier than Solid drives, making them more vulnerable to falls and drops.

Is SSD more reliable than HDD: SSD is more reliable and durable than hard drives. It's a better option for your laptop or computer if you travel a lot with your device.

Is SSD better than HDD for Data Recovery?

HDD is easier to recover data from than SSD because data is stored on spinning disks in an HDD. If the hard drive is damaged, the data can still be accessed by changing the read/write head. However, data stored in SSDs can be more difficult to recover. This is because data is stored in flash memory chips, and any minor circuit damage could lead to complete data loss.

Verdict: Hard disks are a much better choice if you need to store highly valuable data and backups. If you are using SSD, make sure to regularly take backups or cloud sync the data.

SSD and HDD Difference in Performance

HDD performs better than SSD when it comes to writing large files. This is because SSDs have to erase data blocks before writing new data. This process is called write amplification and it slows down the SSD. HDDs don't have this problem since they can overwrite data without erasing it first.

However, under general circumstances, Solid state drives perform better at reading and writing files.

Which has better performance: SSD vs hard drive: If you need to write large files often you should go with HDD. In other cases, SSD is the better choice.

Solid State Drive Vs Hard Drive Availability:

Currently, SSD is pre-installed in high-performance laptops and desktops to complement the high-end processors, RAM, and GPU. However, most computers in offices and homes still have hard disk drives as storage devices.

Verdict: SSD is readily available in new Laptops and desktops.

HDDs tend to make more noise than SSDs since they have spinning disks. The noise is created by the spinning disks and the read/write head moving back and forth. On the other hand, SSDs are much quieter since they don't have any moving internals.

Verdict: SSDs are a better choice if you are looking for a quiet device.

Power Consumption

HDDs consume more power than SSDs since they have spinning disks. The disks need to be spinning all the time for the data to be accessed quickly. On the other hand, SSDs don't have any moving internals and only use power when they are reading or writing data.

SSD HDD difference in power consumption: If you are looking for a power-efficient storage device, SSD is the better choice.

Solid State Drive vs Hard Disk Drive Lifespan

HDD is widely used in computers and servers around the world with an average lifespan of 3-5 years under general conditions. The age might vary depending on the read-write frequency. SSDs are relatively new and are not tested to the mark under practical circumstances. However, studies and research have concluded that NAND-based SSD could last up to 10 years as NAND chips come with a limited working time span.

Which one is better SSD or HDD for long-term storage: Virtually, SSDs are expected to last much longer than HDDs making them a better choice to store data for a longer time.

Security difference between HDD and SSD

Some of the SSDs have hardware-based encryption to protect data. Any data that is written to an SSD is automatically encrypted making it more secure than HDD.

However, it's difficult for users to use software-based encryption or permanently delete a specific set of data in SSD as it distributes data on all flash NAND chips to increase lifespan.

Is SSD better than HDD in terms of Security: Well, SSD has both advantages and disadvantages when it comes to security. If you want to secure stored data Hardware encryption-based SSD are a better choice. However, HDDs are better when it comes to permanently deleting or software encrypting a set of data.

When should buy a Solid-State Drive instead of a Hard Disk Drive?

Summarizing everything we have written above, here are some cases when you should prefer SDD over HDD: -

· Buying systems/laptops for gaming or extremely fast performance

· Updating existing system when you can’t change processor

· Need smaller storage space on your system

· If you want to store data for a longer time

· If you are planning to use your system in an unfavorable environment: Extreme cold, hot or humid

Pro Tip to get High Speed in Budget System

If you want extremely high speed, larger storage capacity and you are low on budget for SSD. Here is a trick. You can install both HDD and SSD on your desktop/ laptop.

But wouldn’t that make it more expensive? No, you just need to install a 128/256 GB SSD as primary system memory and the rest 512 GB or 1TB HDD as secondary memory. You can install your OS in the SSD and run all games/applications at lightning speed while storing the rest of your data in HDD.

If you Install 512 GB SSD it will cost, you anywhere around $40. However, you can get a 256GB SSD and 1 TB HDD for the same price. Many Budget gaming Laptops have the same configuration.

SSD or HDD: Which is better for a laptop?

While most users consider SSD as a better option for Laptops in terms of Speed, performance, and reliability, it comes down to use requirements last. SSD is great for gaming and high-speed laptops. However, when it comes to storing and processing very large files for animation, video, and servers, HDDs are a much better option.

Even for processing large games like Call of duty and Quantum Break, you need an SSD greater than 1 TB capacity which is extremely costly. The mixed approach of using SSD as primary and HDD as secondary memory could prove much beneficial in most of these cases.
