15 Reasons To Choose SSD Drives Over HDD Drives

SSD Solid State Drives

Solid State Drives (SSD)

What are the two ways in which you can grow revenue from your website? Driving more visitors to your website and boosting your conversion rates, right?

To drive more visitors, it is very important to rank your website in the Top Search results. To rank your website in the top search results, major search engines like Google, are now considering website speed as an important factor for ranking.  According to the latest research, SSD drives are playing an important role in speeding up your website.

Solid-State Drives (SSDs) are non-mechanical data storage devices, which consists of NAND flash mounted on circuit boards rather than hardware. Unlike HDD drives, SSD drives utilize popular form of flash memory NAND to provide fast access to information. NAND is a non-volatile memory with electrical eraser and re-programming capabilities.

The flash memory utilized by Solid State Drives is similar to that used by thumb drives, except the speed and type of memory, which differs considerably between them. The better speed and reliability of SSD flash memory makes it more expensive while making it more suitable for your sensitive data.

Since there are no moving parts, SSD drives are silent and they never disturb your computing experience unlike whirring Hard Disc Drives. SSD drives are energy-efficient storage devices. They require very little power to operate, which results into significantly less heat output by the systems.

Hard Disk Drives (HDD)

Unlike SSD drives, HDD Drives use rotating magnetized platters to collect data. When your computer attempts to access information, the read/write head physically moves over magnetic platters to read or write data. This process can take considerably longer time than readily available SSD data. HDD drives can only access the data faster when it is closer to the read write heads, while all parts of the SSD drives can be accessed at once with equal speed.

Whether you are looking to upgrade your existing system or buy a new PC, you cannot afford to avoid the striking features of SSD drives. Following are the 15 reasons to choose SSD Drives over HDD Drives.


(Solid State Drive)

(Hard Disk Drive)

  • Power consumption is Less.
    (approx. 2 – 3 watts)
  • Boosts battery backup to 30+ minutes.
  • Power consumption is High.
    (approx. 6 – 7 watts)
  • Your laptop battery may drain soon.

More likely to keep your data safe even in worst cases like;

You drop your laptop bag OR
CPU unit has fallen down.

In read/write operation, head fly over the platters rapidly.

Hence, abrupt power off or sudden power outage can cause severe damage.

Very Expensive.
Approx. $0.10/ 1 GB.

Very Cheap.
Approx. $0.06/ 1 GB.


SSD uses NAND flash memory,
It will continue to shrink as time goes on.

HDD uses Platters, they cannot be manufactured smaller beyond certain limit.

Maximum &
Common Capacity
  • 4 TB SSD units are available lately, but still rare and expensive.
  • SSD Units with 500 GB for Notebooks and 1TB for Desktop are available.
  • For Notebooks, HDD Units with 500GB to 2TB are available.
  • For Desktops, HDD Units with 6TB are available.
Operating System
Boot Time

8-12 seconds of average
OS boot-up time.

25-40 seconds of average
OS boot-up time.


SSDs wear out over time because each cell in a flash memory has limited number of read/write cycles.

HDDs eventually wear out from constant use as well.

There are no rotating/mechanical parts, SSD makes no noise. Due to mechanical parts, quietest HDD emits a bit of noise.
SSDs weigh significantly less
approx. only 77g.
HDDs weigh considerably more approx. 752.5g.
Effect of
Magnetism cannot affect the SSD Units. Sometimes magnetism can erase the data.
Required. Not Required.
Since there are no rotating parts, No Vibration. Sometimes, HDD emits little Vibration due to rotating platters.
Opening Speed
Upto 30% faster than HDD. Slower than SSD.
Lower power draw and no moving parts so Little Heat is produced. Due to moving parts and higher power draw, HDD produce More Heat than an SSD.
Copy/ Write
Ranges between
200 MB/s to 500 MB/s.
Ranges between
50 MB/s to 120 MB/s.

SSD vs. HDD Conclusion

While studying the above comparison factors, SSD gets 13 and HDD gets 2. SSD is clear winner here; but again it all depends upon the individual requirements. Undoubtedly, the comparison favors the SSD drives but if you cannot utilize SSD drive features; they are useless for you.

If you are an individual who needs lots of storage and don’t much care about how fast a computer boots up – Hard Disk drive (HDD) is perfect choice for you. On a contrary, if you are performance freak who needs blazing fast bootup times – SSD is the only choice for you.

SSD Drives are an attractive storage option with some great qualities, which make them the perfect choice for businesses seeking to improve speed and efficiency of their operations. While upgrading the enterprise storage options, business owners must measure budgetary concerns against the benefits of SSD Drives.
