Solid-state disk drives (SSDs) are becoming more common in desktop and laptop computers. While SDDs serve the same purpose as hard disk drives (HDDs), there are some key differences in how they work.
How HDDs Work
To better understand how SSDs work, let’s first look at HDDs. HDDs have a range of spinning magnetic disks where data is saved, stored, and accessed. There is an actuator arm that moves over the spinning disks to read and write data. Since the arm must move into the right position over the spinning disks, it can take a little while before data can be saved or read from the drive.
Additionally, depending on the fragmentation of the data, the arm may need to move to different areas on a disk or different disks to save or retrieve data fully. The disks can also become corrupt and develop bad sectors where data can no longer be accessed or saved.
How SSDs Work
SSDs read, write, store, and retrieve data differently. There are no moving parts or components. Instead, SDDs work similarly to flash memory by using semiconductor chips to receive and send data from the drive. The chips are divided into different pages for storing data.
One major advantage of SSDs is their speed. Since there are no moving parts, data can be written and read much faster. The only drawback is when saving over existing data. The SDD has to first transfer the existing data to a blank data block, erase the existing block, then transfer the existing data back along with the updated data.
A second major advantage of SSDs is their reliability. HDDs are considered mechanical devices with moving parts and components that do wear out over time. SSDs do not have moving parts and components, so they tend to last longer.
Can SSDs Crash?
SSDs can eventually crash and stop working. They do wear out but not as fast as HDDs. The only issue is SSDs do not give you any advanced warning they are getting ready to crash. They just stop working.
With HDDs, they may exhibit signs they are getting ready to fail. For instance, you might hear clicking or grinding sounds coming from the drive. You might be notified of data read or write errors too.
Can Data be Recovered from SSDs?
The biggest obstacle to recovering data from SSDs is there is no guarantee the data recovery will be successful. As SSDs are a newer technology, data recovery options are still being developed. As SSD technology matures, more effective data recovery solutions will become available.
However, the best option to protect your data if you use SSDs is to ensure you perform regular data backups.
That being said, data recovery from SSDs is possible using the right tools and equipment. As most consumers and businesses do not have access to these, the best solution is to turn to an experienced data recovery service in Toronto, like Taking It Mobile.
