Apple has updated its Xserve RAID storage system, raising its capacity to up to 10.5TB with the release of new high-capacity 750GB drives.

Xserve RAID drives are hot-swappable. The system itself accompodates fourteen drive enclosures; until now the drives were only available in 500GB maximum capacity.

UK price on the new systems hasn't yet been confirmed and the new high-capacity drives aren't yet available as a build-to-order option on the Apple Store. In the US the new high-capacity Xserve RAID costs $13,799. The standard 7TB configuration now costs £9,399.

The low cost per gigabyte of its RAID system is helping Apple sell into existing infrastructures that use other operating systems, as the product works happily with Windows, Linux, Solaris and NetWare.

“The customers that are using RAID are putting the product in their infrastructure for broadcast, design, video and education,” Doug Brooks, product manager of Apple’s server and storage hardware group, told Macworld US. “We have lots of customers that are very heavy storage users.”

Apple will be selling the higher capacity drives separately, allowing customers of the older 7TB Xserve RAID to update, if they want.
