Access time can be orders of magnitude faster than with a disk, because the data can be accessed randomly - there's no need to synchronize the read/write head with a rotating disk.Īlso, the solid state hard drive uses about 50% less energy (important for laptops running on battery power), makes no noise, and is generally more stable. A solid state drive has no moving parts, so there's no chance the "needle" can scratch the "record".Īnother advantage is that they can access data stored in their memory nearly instantaneously, even when data is fragmented. Have you ever bumped into a turntable while a record is playing? The same type of damage to a hard drive platter can occur when the read head gouges the surface. In other words, they tolerate the Two D's (dust and dropping) better than a traditional hard drive. This means that SSDs are not susceptible to data corruption or operation failures caused by debris or movement. The first advantage is that there are no moving parts. There are several obvious advantages to using a solid state hard drive. Instead of using a storage medium that is magnetic or optical, an SSD is made entirely of semiconductors and typically uses the nonvolatile NAND Flash technology, which gives you nearly immediate access to data in the SSD. While there are several significant advantages to using a solid state drive with no moving parts, price is currently keeping the SSD from taking over the hard drive market for laptop and desktop computers.Īs mentioned previously the solid state hard drive has no moving parts. It was designed using the same technology as USB flash drives, and it is intended to eventually replace the standard hard drive that uses a spindle and platter. A solid state hard drive, or SSD, is the next revolution in computer hard drive technology. Solid state hard drives were introduced to the public at the 2007 Consumer Electronics Show in Las Vegas.
