-
- The PS180 Controller nearly DOUBLES electronically the factory-rated
- storage capacity of REGULAR OXIDE MEDIA Winchester hard disk drives,
- and coupled with PerStor's entirely separate DiskExpander Compaction
- software, it can far more than double (approx 140%) the stand alone
- capacity!! PS180 utilizes the Advanced Run Length Limited 2,7 encoding
- method, giving it a data transfer rate of 9 megabits per second to
- increase hard disk capacity by at least 90%. It provides 31 sectors
- per track and is ROM residence selectable and port address switchable
- to allow you to have more than one HD controller operating in the same
- unit.
-
- The PS180 Controller WORKS WITH VIRTUALLY ANY quality Winchester hard
- disk drive compatible with the IEEE specifications for the ST506/412
- Interface. We have conducted qualification tests on most of the
- popular fixed disk drives in the market today, including MiniScribe,
- Seagate, Maxtor, Newbury Data, CDC, LaPine, Rodime and other models.
- PS180 uses a standard IBM compatible Bios, so it is compatible with
- MSDOS, PCDOS, UNIX, XENIX, and CPM, as well as Novell Netware.
-
- The PS180 Controller is capable of supporting 2 HDs each with 15 heads
- or less and 2,048 cylinders or less. The PS180 has an Advanced Error
- Checking and Correction capability using a 56 bit code to allow twice
- the bit drop-out factor of normal controllers. In addition to this 56
- bit ECC, there is a sector buffering RAM chip on the board itself to
- overcome speed defferences with the drive, and it has a 25 megabit
- data recovery circuit.
-
- Besides the 90% Actual Electronic Increase of 31 Sectors Per Cylinder,
- the separate PerStor Disk Expander Compaction Software System is also
- packaged with the PS180 Controller as a NO-COST OPTION, providing a
- data derived 50% further increase in capacity above the 90% increase
- secured by the PS180. Disk-Expander is enhanced by a cache access
- method that lowers the average access time to about 15ms when used.
- However, this additional compaction software system requires a DOS
- 3.1 or higher operating enviornment.
-
- Getting MORE THAN TWICE THE STORAGE CAPACITY out of YOUR HARD DISK is
- easy and cost effective with the PS180 Controller and DiskExpander.
- You get benefits of full compatibility with your system, increased
- capacity, decreased access time, error correction, and much more!!
