Solid State Drive Myths

Solid State Drive Myths

Solid State Drives (SSDs) are being used extensively across operating systems like Mac and organization data storage. But some people still refuse to take the advantage that SSDs offer over their slower mechanical counterparts – hard disk drives (HHDs). This is just because of misconceptions over how the faster, all-electronic SSDs work.

Solid State Drive Myths

Here are a few things that can clear your knowledge on the matter and help you make an informed decision.

When solid-state drives entered the market, the cost of a Gigabyte was much more in SSD than equivalent storage space on an HDD. But since then, flash memory technology has progressed and prices have dropped. But the fact remains that SSDs cost higher than hard drives. However, cost savings can be seen when you look at the amount of performance. For example, an SSD does the job of 40 hard disks, but does not cost 40 times as much.
SSDs consume less power and hence, require fewer resources to cool them and space to house them. Fewer SSDs are required to complete the job of a rack of 500 HDDs, essentially saving real estate in your data center.

SSDs offer a great deal of security for your most valuable data and don’t compromise performance. They are self-encrypting and offer enhanced hardware-based security features. Advanced encryption standard (AES) is an internationally recognized specification for the encryption of data.
Hardware-based encryption means that data is automatically encrypted and decrypted through the AES which is built onto the SSD. It is more secure and efficient than software-based encryption where data encryption lies within the threshold of a computer software and makes data vulnerable.

The most pain-staking aspect of a computer system going awry is when it undergoes a drive failure. An HDD failure can take up a number of hours and amount to unproductivity and additional efforts for IT. On a personal computer, there is time wasted in lost memory, recovery and recovery software for the operating system.
SSDs undergo extensive testing and are engineered to reduce costs and minimize downtime due to storage-related failures. Unlike HDDs, SSDs have no moving parts. They are able to withstand shocks and vibrations and don’t lose data.
They provide consistency in performance. The health can be monitored and this predictable reliability and the absence of moving parts, give SSDs a huge advantage over the high failure rate of HDDs.

Life of an SSD is calculated by the number of “writes” and not its time. The SSD works like a cell system in the human body. Before new data is added to a directory, the old data must be removed first. In the repeated process of such an occurrence, a drive is able to withstand a limited number of erasures before it becomes unusable.
SSDs contain billions of directories. In terms of data, it is an enormous that is written and deleted every moment of every day of the drive’s life. For example, a 100GB SSD is capable of offering 10 drive writes per day and it can support 1TB of writing each day, 365 days a year for five years.

5.High performance computing
SSDs are incredibly fast and HDDs are nowhere close when it comes to speed. Since HDDs use mechanical actuators, they are moved to precise locations on a spinning platter to read/write data. There’s a limit to how fast the platters can spin and the actuators can be moved.
SSDs can provide productivity improvements for most Mac users, simply because of the instantaneous access to storage made up of semiconductors.
