The Satellite Radius 11 L10W-B has an HDD storage medium which is better than the SSD storage medium found on most notebook PCs that are a comparable age to it. HDD is a traditional storage drive which stores the information on magnetic disks. HDD drives are slower than other forms of storage such as solid state drives (SSD) and flash drives.
An HDD storage medium is in fact the worst storage medium across all similar spec notebook PCs that were launched around the same time as the Satellite Radius 11 L10W-B.
An SSD storage medium is the best storage medium amongst comparable types of portable PC.
