Majority of the advantages of Solid State Drives over Hard Disk Drives can be attributed to the way these are assembled. In a Solid State Drive several interconnected flash memories or circuit assemblies as memories are used to facilitate storage. This enables data storage even in the absence of power supply by obviating use of mechanical or movable parts. On the contrary, a Hard Disk Drive uses metal disks or plates that keep on revolving and are provided with a magnetic coating for data storage.
Understanding SSD storage
In recent years the use of SSD has seen a sharp rise on account of their obvious benefits over Hard Disk Drives. One of the most interesting benefits of an SSD is related to speed of website. It is also linked to a rise in website visitors who prefer to stay on fast loading websites. Since leading search engines attach great importance to speed of websites, an SSD is found to contribute significantly to faster speed of website and a subsequent improvement in search engine rankings.
SSDs or Solid State Drives are also referred to as non- mechanical data storage devices. These are basically made by using NAND flash that is mounted on circuit board instead of any hardware. In order to enable ultra-fast access to data, SSD uses the most sought after forms of flash memory NAND. It is regarded for its non volatile memory that has outstanding capabilities of re-programming and is provided with electric eraser.
There are many similarities between the flash memory offered by SSDs and thumb drives. There is however a major difference between the two types of memory devices in terms of the speed of access and type of memory. SSDs are costlier than thumb drives and are designed for faster and reliable performance. This makes SSD and ideal choice for storage of critical information.
Lack of rotating or mechanical components significantly reduces power requirement for operating SSDs. This also explains why there is almost no heat generation during running of SSDs.
HDDs or Hard Disk Drives
Hard Disk Drives consist of magnetized platters that are designed to rotate whenever the information is being accessed by the computer. The read or write head of the drive is made to move over the magnetic platter to perform its operation. The entire operation needs far greater time than SSD drives. It should be noted that HDD can only access data faster if it is in proximity to the head, while SSDs are able to access entire data with same speed.
Notable advantages of SSDs over SSDs
Having briefly reviewed major attributes of SSDs and HDDs, let us dig deeper into some the most compelling advantages of SSDs over HDDs.
Faster data accessibility- The very fact that SSDs are devoid of any movable parts facilitate them to access data much faster than Hard Disk Drives that need time to access data due to physical movements of mechanical components. Better speed of SSD can be also attributed to lesser data fragmentation as compared with HDD. In terms of comparison, an SSD offers 25 to 100 times faster performance that enables greater bandwidth for enterprise level computing, faster boot time, and rapid file transfers. SSDs are also reckoned for faster copy/write speed that is at least four times faster than HDDs.
Greater energy efficiency- In terms of power consumption, an HDD scores over SSD due to presence of moving parts including magnetic metal platter to read or write data. Solid State Drives are highly energy efficient and moreover produce no heat. This also makes SSD a preferred option in computers that can perform better with reduced exposure to heat.
Superior durability- There is always a possibility of shudders or drops in case of Hard Disk Drives. This can result in loss of data and a total breakdown of the device. This drawback is attributed to the involvement of moving parts that are mechanically assembled together. In contrast, Solid State Drive has no such issues and can seamlessly perform due to its resistance to drops or shudders. This attribute of durability is of great use in application of SSDs for mobile computing.
Silent operation- SSD is regarded for noiseless operation with absence of moving parts such as a rotating magnetized platter or the movement of read or write arm. In case of HDD, there is a constant noise production as well as vibration due to moving parts.
Compactness of size- This is an inherent characteristic of Solid State Drive, and is of great benefit for its use in portable computing devices. However, Solid State drives are bulky in appearance and also need frequent maintenance due to presence of moving parts. This is also applicable in terms of overall weight and it is observed that an HDD is almost ten times heavier than an SSD.
Solid State Drives are extensively preferred dust to their faster performance and reliable storage attributes. If you are looking for an ideal storage option the enables ultra fast access and super quiet performance, then a Solid State Drive would be the right choice in comparison with a Hard Disk Drive.
