ProStor Ramps Capacity, Challenges Tape

Removable disk cartridges are getting bigger, making RDX technology an increasingly viable alternative to tape, according to ProStor, which today announced its first 500-Gbyte offering.

ProStors RDX technology, which comprises a "dock" and 2.5-inch removable disk cartridge, previously had a maximum capacity of 300 Gbytes, although the vendor has now certified a 500-Gbyte disk drive.

By boosting its drive capacity by 67 percent, ProStor’s RDX offerings are more likely to lure users away from tape-based backup, according to Chris Bukowski, the vendor’s senior product marketing manager.

”As the basic disk drives for servers and laptops grow, we’re keeping pace,” he says, promising even higher capacities in the future. “By the end of this year, early next year, we will have a 750-Gigabyte cartridge, and, probably, three quarters or a year after that, we will have a Terabyte cartridge.”

Imation, which, along with Tandberg, licenses RDX technology from ProStor, was quick to jump on the 500-Gbyte bandwagon today. In a statement released this morning, Imation announced that it will offer a 500-Gbyte cartridge for SMBs later this month, priced at $550.
