Types of Hard Drives
SSD(new) and Disk Drives(old): SSDs have no moving (mechanical) components. This distinguishes them from traditional electromechanical magnetic disks such as hard disk drives (HDDs) or floppy disks, which contain spinning disks and movable read/write heads. Compared to electromechanical disks, SSDs are typically more resistant to physical shock, run silently, have lower access time, and less latency. However, while the price of SSDs has continued to decline over time, consumer-grade SSDs are still roughly four times more expensive per unit of storage than consumer-grade HDDs.
Most drive corruption occurs at a superficial level. That means the drive is still functional but has a corrupted system file(boot file) caused by virus and malware. Some have bad sectors in the drive path that makes the system slow or at times can cause blue screen or continuous "wheel spin". This is a Level 1 kind of problem that can be resolve in-house. Data extraction may take a day or a week. On a LEVEL 2, this requires a certified clean lab room to dis-assemble the drive. We outsource this process to a trusted vendor that we have been using for years, trusted and with a 99% success rate. Please note that we don't service encrypted drives.
