How SSDs are Better than HDDs and is it Possible to Perform Data Recovery from a Failed SSD?
A Solid State Drive (SSD) also known as solid-state disk is the latest technology used for data storage. It uses a series of integrated circuit (IC) as memories to permanently store the data. This avoids the need to have any moving mechanical component and is not considered to be categorized under hard drives.
The latest SSDs that are being shipped with computers use NAND-based flash memory. NAND flash memory is a type of non-volatile storage technology, which regains the data even without power.
Benefits of SSD Technology
SSD Technology uses semiconductor memories organized in an array, which makes it different from the disk drives. Such an arrangement has many benefits. Some of them are listed below.
- 1. Provides a better data transfer rate as compared to traditional electro-mechanical disk drives
- 2. Reduced seek time and latency
- 3. Provides faster boot time
- 4. Much quieter and long lasting
- 5. Used as an enterprise storage solution to provide better performance
- 6. Avoids the need to add additional servers
- 7. Can be employed in a SAN as a ‘super cache’, thus making the frequently accessed files access much faster
You can now use your Mac as before with all the data intact. If you still face problems, you should visit an Apple retail store.
Difference between SDD and HDD Technology
The choice between an SDD and HDD totally depends upon the need, preference, and budget of the user. SSD is comparatively a newer technology as compared to HDD and is still to be explored by a majority of the user. It uses microchips to store information and looks more sophisticated as compared to other memory devices.
SSD has fewer parts as compared to HDD, which has a number of moving mechanical parts. A hard disk uses a read/write overhead to access information from the platter where the data is stored.
On the other hand, SSD uses a microchip to store information and is considered faster. This is because; the HDD requires more of mechanical movement as compared to SDD.
A system using SSD boots up faster as compared to the system using HDD. It is seen that on an average SSD takes 22 seconds to boot and an HDD takes 40 seconds to boot.
The SSD uses a non-volatile flash memory based on the concept of NAND. With this, the data remains permanently stored even if the power is turned off. There is no such flash memory involved in hard drives.
In SSD, you can perform various operations on the data including Read and Write. It has an embedded processor, which act as a controller to read and write the data. It determines the speed with which the data is written and read. On the other hand, HDD uses a mechanical arm to read and write the data.
Encryption is an important means to secure data present on a storage device. There are various encryption techniques that can be used. Both HDD and SDD use Full Disk Encryption (FDE) mechanism. However, this supported only on a few models of SDD and HDD.
SSDs are much portable than HDDs. More often, a SSD in incased in a plastic or metallic case. In addition, it uses the same form factor of 1.8", 2.5". or 3.5" size of a hard drive.
Because of the more integrated chips and lesser mechanical components involved in a SSD, SSD is comparatively costlier than HDD. Even though the price of SSDs has been falling, it is cheaper to get HDDs with larger storage space.
SSDs draw less power as compared to HDD. It consumes almost half the power as compared to HDDs and boosts the battery up to 30 minutes.
Noise and Vibration
Since there are no mechanical moving components present in SDD, there is not any vibration or noise present. On the other hand, HDD produces noise and vibration due to the presence of moving mechanical components.
In spite of having some many advantages, we cannot say that SSD is completely better than HDD. HDDs are still the popular choice for many users. A user might prefer HDD if,
- Up to 4TB of storage capacity is required.
- Cost is a factor.
- Performance is not a matter of concern.
On the other hand, a user would surely go for SSD, if cost is not a concern for him and can work around limited storage capacity.
However, in spite of having so many advantages with SDD, it can fail at times. No doubt, it reduces the chance of failure and data loss, but you might land in some unavoidable situation while working with SSDs. An SSD might fail due to some issue with the electronic component leading to severe data loss. In such a situation, it is very important to get back the lost data as soon as possible.
How to regain data from failing Solid State Device (SSD)?
Both HDDs and SSDs are used to store data and can fail at times. However, the rate of failure of SSDs is lesser as compared to HDDs. This is because of the lack of any mechanical moving component. But, data loss is uninvitable. SSDs can also fail without any prior information. As HDDs, data can also be recovered from SSDs. Since, SSDs use a different mechanism to store data, the recovery process might also differ. It is always recommended to have a Data Recovery tool to recover lost data from Windows based systems. The recovery process might also differ depending upon the software being used.
Stellar Phoenix Windows Data Recovery software is one of the most trusted software to recover data from failed SDDs. It supports recovery of photos, audios, videos, and other multimedia files from failed SDD. With this software, you can quickly scan the storage device. The scanned result is displayed in a tree like structure, from where you can select any files and check its preview. Finally, you can save the recovered items in a desired location. The tool also supports data recovery from any external SSD device attached to Windows.
