Jackhammer Models 0300, 0301 and 0304 Hard Drive Shredders

Hard Drives come in various shapes and sizes. The Hard Drive Suppliers and Computer Industry refer to them as1.8”, 2.5” or 3.5” Form Factor Drives. These “form factor descriptions” refer to the size of the “platters” that are housed within the drive casing itself and account for over 90 % of the drives in use today.

Another way to describe hard drives is by the computer to which they are integrated. You will hear the term Notebook or Desktop / Mobile or Server / Enterprise Drives as a common description.

A “Notebook Drive” is based on 1.8” or 2.5” form factor. Because of the physical size of notebook computers, the drive itself needs to be much smaller than a desktop drive. The typical dimensions of a 2.5” form factor Hard Drive is .37” H x 2.75” W x 4” D. The 1.8” form factor Hard Drive is even smaller at 31” H x 2.16” W x 2.8” D.

Both 1.8” and 2.5” form factor Hard Drives can be fed into all three of the SEM Jackhammer Shredders with ease and can be shredded at the maximum rates specified by each system.

A “Desktop Drive” is based on 3.5” form factor or size of the platters. These drives are integrated into standard Desktop Personal Computers, Small Servers and/or Large Enterprise Storage Systems. The typical dimensions of this type of drive are 1” H x 4” W x 5.75” D. The metal and steel casings used in these drives vary by manufacturer.

The SEM Jackhammer series is designed to accept 3.5” Desktop Drives yet the output is dependent upon the amount of metals used by the manufacturer and will be less than the maximum rates specified by the each system.

Hard Drives come with various “interfaces”. The common ones are PATA ( IDE ), SATA, SAS, FC, USB and/or SCSI. You will also hear about LMR or PMR drives. None of these terms impact the size or dimensions of the drives themselves.

Below are pictures of typical 1.8” and 2.5” Hard Drives as well as 3.5” Drive with the inside of the drive exposed.
