The disk wars: Solid State Drives vs. Hard Disk Drives

The Challenge

There are two types of compact disks in use these days; the advanced Solid-State Drives (SSDs) and the traditional Hard Disk Drives (HDDs). Being the most perceptible difference, the former one is generally used as an external storage option. You can connect the drive with a computer or laptop using a USB cable. Meanwhile, the second one often comes fixed with a computer or laptop. HDD is frequently a part of the computer’s hardware. However, it can also used as an external drive connecting with a USB cable. And SSDs have started to appear within the modern laptops and netbooks also.

SSDs Vs HDDs

In fact, there is a huge difference in the way the data is stored and retained from the both the disks. This feature is often counted as the major distinction between the drives. SSDs make use of microchips to store and retain the data. While HDDs use spinning disks to store the data. The former one has no moving parts like the read/write heads of the latter. There are many more differences between HDDs and SDDs in speed, performance, battery consumption, and others. Go through our comparison between SSDs and HDDs under the light of a pick of measures.

Reliability

Both HDDs and SSDs are used for a single purpose, i.e. to store data and to retain them whenever required. Therefore, reliability of the disks has been a biggest concern of customers. We know that SSDs store your data in NAND-based flash memory. The device does not have any moving write/read heads like HDDs that store the data in spinning disks.

Winner: The most advanced SSD is the winner when reliability is in the discussion point. Since the data is stored in microchips, the entire process is more reliable than HDDs.

Speed

Needless to mention, speed is a big factor a user might consider before purchasing a compact storage disk. Since the breadth of data is increasing with every customer, more competent disk is a necessity. Thanks to its dependence on NAND-based flash microchips, SSDs offer better speed than HDDs that work on spinning disks.

Winner: Speed in storing and retaining data is always the requirement of a consumer. Therefore, SSDs are adjudged the winner under this category too.

Capacity

Solid-State Drives that depend on the most advanced technology to store data have better memory capacity than HDDs. The explosive growth in the evolution of high-performing microchips has increased the capacity of SSDs to HDDs that still depend on spinning disks to save the contents.

Winner: It is again SSDs, because in the new world, the one with more capacity in certainly the winner over the one with less capacity.

Power Consumption

No one needs to be made aware of the mounting energy crisis. It is proven that SSDs use only less than one-third of the power HDDs need when the disks are in running. And amazingly, SSDs need only 95 percent less power than HDDs when the disks are idle.

Winner: SSDs win over HDDs because the former uses less energy.

Verdict

The technology world is looking for more sophisticated products with less power consumption, but with high performance, speed and size. Reading the above comparisons, we can simply conclude that SSDs are doing better than HDDs. There is nothing surprising in it, though, because SSDs are the outcome of the recent technological advancements. Meanwhile, HDDs are the products of the past technology. Anyway, price is still the barrier that prevents many users from going for SSDs. The solid-state drives are priced higher than the conventional HDDs.
