Meantime PC Week hears that Iomega Corp has a hotter property up its sleeve in the form of an exchangeable Winchester cartridge drive code-named Viper, which stores 1Gb in a 3.5 form factor and is pitched at the market largely created by SyQuest Technology Inc. Set for r elease next quarter, it is expected to carry a price of $575 for an external version and $500 for an internal kit. Cartridges are expected to cost about $100 each. The paper also hears that the Fast SCSI-2 mechanism will have an uninterrupted sustained data transfer rate of 3.5M-bytes to 5Mb per second, more than double that of SyQuest’s 270Mb SQ3270 mechanism, and the same 14mS average seek time.
