VST Technologies has unveiled a new range of hard drive and removable media storage systems based on FireWire and USB for Macs at the MacWorld Tokyo exhibition – following on from the big announcement of new Powerbooks, G4s and a new special edition iBook. The company's new FireWire hard drives feature both FireWire and USB ports, meaning it can be used for transporting large amounts of data between newer FireWire-equipped Apple systems and older models that support only USB. Available with capacities from 6GB to 25GB, the new drives will ship in April, said Vincent Fedele, founder and chairman of VST Technologies. VST's new FireWire RAID (redundant array of independent disks) array accommodates four 25GB hard drives to give the user a maximum storage capacity of 100GB per array. The drives support data transfer at up to 32MB per second and can be stacked up to four arrays high for a total of 400GB of storage space. The entire array is also compact, measuring 13-by-18-by-25 centimetres, and includes a lithium-ion battery pack that provides for up to two hours of use. Compatible with all FireWire-equipped Apple computers, the system is scheduled to ship in March. UK prices as are yet unconfirmed. Also new were two FireWire Zip drives, each with the ability to support the 250MB Zip format. One supports FireWire and the other Apple's new PowerBook, announced earlier today, and both are available immediately, said Fedele. Sitting in one corner of the company's booth was a pre-production version of a new drive scheduled to ship within the next three months. Supporting conventional floppy disks, SmartMedia and CompactFlash cards, the device connects to Macs via USB and each of the three drives appears as a different device on the user's desktop. This enables files to be easily read and written to the disks and even transferred between them, said Fedele.
