The Systems Division of Priam Corp, San Jose, California, this week introduces high-capacity Run Length-Limited Winchesters in capacities of 75Mb, 100Mb and 230Mb for the IBM AT, compatibles and 80386-based Personalikes. The kit includes RLL drive, controller, interface cables and installation and partitioning software and internal and external versions are available. The controller uses the 2.7 RLL method of encoding that enables up to 50% more data to be recorded on a disk than the more commonly used Modified Frequency Modulation encoding schemes. This in turn produces a 50% increase in data transfer rates resulting in higher performance. The seek time for the 75Mb and 100Mb versions is 28mS, falling to 20mS for the 230Mb version. The internal drives, with RLL contrller, are the ID75 at $1,700; the ID100 at $2,100 and the ID230 at $3,800. The external RLL storage systems join Priam’s existing StorageSpace ED series and are the ED75 at $2,000, the ED100 at $2,400 and the ED230 at $4,100. They are also available with combination Winchester/floppy controllers for $50 extra. Volume production of internal RLL systems begins in May with the external models following in June.
