The Lenovo P900 has an HDD storage medium which is faster than most desktop computers of a comparable spec and age to it. Most many processor core PCs that were launched around the same time as it have a Flash storage medium. 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.
There are a number of other HDD personal computers currently available that you might want to consider including cheaper PCs such as the P900, the D30, or the P900 all from Lenovo.
If the storage speed of this personal computer is not fast enough for you then you might want to consider the P900 ($3,232.33) (SSD), or the Thinkstation P500 (SSD) both from Lenovo.
