Both HDDs and SSDs are storage devices and each holds a large market share. HDDs are more reliable compare to SSDs. However, an SSD is faster than an HDD. The overall operational life of an HDD is greater compare to an SSD. There is a lot more to learn about HDDs and SSDs. This post in the following sections aims to inform the reader about all they need to know about HDDs and SSDs.
A Brief Introduction To An HDD
As per the insights offered by an HDD and SSD data recovery expert associated with a revered data recovery firm, the working principle of an HDD (hard disk drive) is similar to a record player. An HDD would have a platter or a stack of platters that rotate around a spindle. The platter or platters of an HDD can spin at a speed of 5,400 or 7,200 RPM. An HDD records data on the platter(s) by making alterations in the magnetic field of the platter(s) with the help of the armature (or the read/write head) that hovers above the surface of the platter(s).
Features Of An HDD
- An HDD is one of the most reliable forms of data storage devices.
- An HDD’s operational life is longer than an SSD given the HDD is being run in a temperature and moisture-controlled environment.
- HDDs are cheaper than SSDs.
- It is easier to retrieve lost data from an HDD than an SSD.
- HDD data recovery cost is lower compare to SSD data recovery cost.
A brief introduction to an SSD
An SSD (solid state drive) got its name as its internal components are fix or are perpetually in a solid state! An SSD saves data on its integrated circuits.
In simple words, an SSD is an enclosed small motherboard that is designed to perform only three functions – read, write and locate data as per the inputs of the end-user. SSDs save data using flash memory. It means that data will not be lost from an SSD even when its power supply has been cut off since it will store data on computer chips that can retain data with or without an active power supply.
Features Of An SDD
- SSDs can read, write and locate required data instantly.
- SSDs need less power to run properly.
- SSDs don’t have any moving parts. Hence, their dimensions are always smaller than an HDD.
- The latency of SSDs is negligible, especially when compared to the latency of an HDD.
Comparing An HDD With An SSD
- According to expert hard disk data recovery professionals, the overall performance of an SSD is way better than an HDD.
- SSDs are more reliable compare to an HDD as the former does not have any moving parts inside it like the latter. Hence, the operational life of an SSD is not hampere due to wear and tear.
- Users who prefer SSDs do not need to periodically back up their data or create redundant copies of the data in other storage devices.
- An SSD weighs less than an HDD.
- The dimensions of an HDD are still large compare to the already limited dimensions of an SSD.
- An HDD entails a higher latency factor, especially when compared to the negligible latency factor of an SSD.
In the end, it all boils down to the preference of the end user. Irrespective of the benefits offered by an HDD or an SSD, the end user’s needs would dictate what they would install on their computer. To learn more, it would be best to consult with the experts associated with a data recovery firm as they can shine their expert light on the matter!
