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,
lets 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.
