SSD vs HDD. Which one is better for you?




SSD vs HDD. Which one is better for you? I have seen many computer user have problem in choosing in SSD and HDD. In this article you will get your confusion solved. SSD ( Solid State Drive ) and HDD ( Hard Disk Drive )  are similar in their physical specs, but they store data differently with different technology. There are drawbacks and benefits to each types of drive, and deciding on which type is right for you depends on how you use your PC. In this article we will show you how each of them works and what it means for you. So let’s start.


In short and fast comparison.

Now for details on SSD vs HDD:


HDD



The  technology of HDD is well known and well tested technology. It have been around 60 years, steadily increasing data storage size and decreasing physical size. HDDs rely on platters to read and write data.

How it works:


HDD consist of one or more magnetically sensitive platters, an actuator arm with a read/write head on it for each platter. A motor to spin platters and move arms.  An I/O controller and firmware tells the hardware what to do and communicates with the rest of the system.

The platters spin at preset speeds i.e.  4200 rpm to 7200 rpm for consumer computers. Those speeds correlate to read/write rates. The higher the preset speed, the faster a HDD will be able to read/write data.

Drawbacks of HDD:


Its drawbacks are a result of the mechanical parts used to read / write data, as physically retrieving data takes more time than that of electronically. The mechanical parts can skip or fail if they are dropped or not handled properly. HDDs are heavier and use energy than comparable to SSDs.

Benefits of HDD:


The benefits of hard disk drive are that they are a well  known and proven technology. They are frequently less expensive than a SDD for the same storage capacity. Currently, HDDs are available with more storage capacity than SSDs.

SSD



It uses flash memory to deliver super performance and durability. As we see that HDD have a lots of small, moving parts inside it which is to go wrong and you could lose your important data. But in SSD, with no moving parts, it is more durable, faster and uses less energy. It is based on NAND technology, so let’s see how it works.

How SSD works (NAND technology)?


We can call SSD a large USB drive as both of them use the same base technology i.e. NAND. NAND, the technology in SSD, is a kind of flash memory. At the lower level, floating gate transistors record a charge to store data. The gates are organized into a block.  An SSD controller that performs several functions, including keeping track of where data is located.

Drawbacks of SSD:


SSDs are based on newer technology. They are more expensive than HDDs. The lifespan of an SSD isn’t as long as that of an HDD.  It can be harder to find large capacity SSDs. HDDs are approx. 2.5 times larger than SSDs.

Benefits of SSD:


It do not use mechanical parts so lose of data is low. SSDs deliver faster load times for games, application, and movies. Due to its technology, they are lighter and better able to withstand movement and drops. In addition, Solid state drive use less energy, allowing computers to run cooler.

Conclusion:

Finally at the end of this article I hope that now you are well known about SSD vs HDD and you can choose one as your need and budget.
