SSD vs. HDD: What’s the Difference?

Both SSD and hard drive serves the same purpose. They boot your computer and holds your applications, personal data. But each storage kind has its own set of inimitable features. How? How is SSD different from HDD? Well here’s the answer.


  1. Cost: SSD costs more than traditional hard drives. For instance, 1TB internal hard drive cost ranges between $40 and $50. Since old and more established technology is used in hard drive preparation thus it remains cost effective.
  2. Max and Common Capacity: Consumer-oriented SSD are out at 4TB capacity, but they are exceptional and expensive. Where, you can easily find a 500GB hard drive, which is considered as the prime hard drive. Generally, high-end systems (multimedia) users need even more than common drives with 1TB to 4TB capacity. After all, it is the simple fact that the more storage capacity, more stuff it can hold on your system.
  3. Speed: This is the lustrous thing about SSDs. An SSD- fitted computer will take even less than a minute to boot, in fact, it just needs few seconds.

But, a hard drive equipped PC need comparatively more time to speed operating specs, and to boot. Thus, a PC or Mac with an SSD loads, launches, functions apps, and transfers data faster. The extra pace is the key difference between SSD and HDD.

Note: If you have lost or deleted important files, photos or any sorts of data due to any cause on your Mac machine then try Remo Recover and easily recover data from MacBook Air, Pro etc. in no time.

  1. Fragmentation: Hard drives are best fitted to work with larger files, which are present in contiguous blocks due to its rotary recording surface. When your HDD started to fill up, large files stored on it scatters around the disk platter. This makes the drive to grieve from fragmentation. So, this clears that as time rolls fragmentation increases. Efforts are made to minimize this, however, fragmentation is not eliminated completely.

But, SSDs don’t. And, with the absence of physical read/write head data can be saved anywhere. Thus, SSDs are fundamentally faster.

  1. Durability: As there are no mechanical (moving) parts present in an SSD, it is the most probable way to safeguard your files from dangers of physical damage caused due to incidents like dropping of the laptop, shaking of PC during its operation etc.

In the case of hard drives, read/write heads will be halted when the system is turned off, but during their normal operation, they will be flying over the drive’s platter. Moreover, even HDDs parking brakes have borders. Thus, HDDs cannot withstand physical pressure or shocks.

  1. Availability: Hard drives can be easily adopted even with older systems, but SSDs are more established in recently released laptops. That says, manufacturers like Western Digital, Samsung, Seagate, Toshiba, and Hitachi etc. are still functioning in supportive of the hard drive rather than SSDs.
  2. Form Factors: The Main constraint of the hard drive is its size. As hard drives depend upon spinning platters, there is a boundary to how small they can be built. If the HDD is smaller then, there arises a main issue “storage capacity”.

But, SSDs have no such restraints. They can continue to shrink even more as time rolls. Currently, SSDs are available in 2.5-inch laptop drive-sized containers (for convenience sake).

  1. Noise: Even if it a noiseless hard drive, it will assuredly produce a bit noise when it is in use, as it contains a spinning or the read/write arm, which is moving back and forth continuously. This happens especially if your system is banged or improperly installed in an all-metal. Faster hard drives will generate more noise in comparison with slower ones. But, SSDs makes no noise because they are non-mechanical materials.
  2. Power: Typically, in hard drives, most of the supplied energy will be wasted in the form of friction, noise, heat etc.

But, an SSD doesn’t spend provided power (electricity) in spinning up a platter from a standstill, thus rendering an efficient outcome is possible in SSDs.

Who wins the race?

Hard drives triumphs on price, capacity, and availability. SSDs shines at speed, roughness, form factor, noise, or fragmentation (a chunk of speed).

Thus, it is your requirement finally and based on it, you can pick the one, which meets your demand.
