Hard Drive-SSHD vs. HDD: What's the Difference?

HDD and SSD or SSHD Explained

The customary turning hard drive (HDD) is the fundamental nonvolatile stockpiling on a PC. That is, it doesn't "leave" like the information on the framework memory when you kill the framework. Hard drives are basically metal platters with an attractive covering. That covering stores your information, whether that information comprises of climate reports from the most recent century, a top notch duplicate of the Star Wars set of three, or your computerized music gathering. A read/compose head on an arm gets to the information while the platters are turning in a hard drive casing.

Here are the Advantages and Disadvantages:

Both Solid State Hard Drives SSHD's and Hard Disk Drive HDD's do likewise work: They boot your computer, store your applications, and store your own documents. Yet, every sort of capacity has its own particular extraordinary list of capabilities. The inquiry is, what's the distinction, and why might a client/user get one over the other? We separate it:


  • The speed of a Solid State Hard Disk Drive is not constrained by its parts, because there are no moving parts to a Solid State Drive
  • Only a series of wires that moves at the speed of electricity.
  • Many SSHD's require lower power and produce less heat, resulting in a decrease in electrical usage and a longer lifespan, especially in laptops that are prone to overheating.
  • Because there is no disk to spin, a Solid State Hard Disk Drive can start up over 20-25 times faster than the standard hard drive.
  • There is no noise, except in the case of the higher capacity storage spaces that tend to have cooling fans attached.
  • Both flash and DRAM Solid State Drives run at faster speeds than hard drives and continue to run at those speeds regardless of the amount of data being accessed.
  • Any physical occurrences, such as vibration, high movements or temperature fluctuations, do not affect SSDs to the same degree because there are no moving parts to break.


  • The Solid State Disk price per gigabyte is much higher than hard drives, so an upgrade to the same GB capacity can incur some considerable costs. As of 2016 the cost of Solid State Drives have dropped by a lot. Check Amazon to compare prices on SSHD's.
  • While they are able to withstand movement, they are vulnerable to power loss and electrical/magnetic currents much in the same way as flash cards.
  • Currently there are very few large capacity SSD models, though this is expected to change drastically over the course of the next few years.
  • Flash SSD have limited write cycles. It is estimated that these write cycles will last until long after the computer is still being used, it is possible that some files could use write cycles often enough that it affects the owner/user.
  • Despite requiring less power, many SSD still use more power than the standard hard drive, especially when idle. This can cause laptop batteries to use up more quickly.

Bottom Line:

Solid State Drives (SSD's) today are far more reliable, have greater endurance and perform better (in some cases, two to three times better).
