The storage speed of this personal computer is HDD, which is typical of many similar spec PCs that were released around the same time as it. A Hard Disk Drive (HDD) is the traditional storage method for computers. A HDD stores the information on magnetic disks. HDD drives are cheap, but they are slower than Flash and SSD bases storage systems.
If you want a computer with a faster storage speed then you might also want to consider the M740 (£1,513.20) (SSD), or the W530 (£1,035.64) (SSD) both from Fujitsu.
