IBM introduces high-performance hard drive

IBM is shipping a new hard drive for desktop computers that uses a technology called "tag 'n seek," which increases its performance by up to 20% over competing hard drives, according to the company.

The Deskstar 180GXP tags commands sent to it from the host processor in a desktop computer. By identifying and classifying different commands issued to the hard drive, it can prioritise those commands for more efficient processing of data, IBM said.

This increases performance by allowing the host processor to take on other tasks, and decreases the seek time, or the amount of time needed to locate a specific piece of data.

The drive features a maximum capacity of 180Gbytes, with a base capacity of 30Gbytes. It uses up to 8Mbytes of cache, and runs at 7,200 revolutions per minute.

NexSAN Technologies will use the Deskstar drives in new RAID storage products, which will allow it to compete with SCSI and Fibre Channel products.

IBM entered into an agreement earlier this year to merge its hard drive operations, with Hitachi, which purchased the majority of IBM's hard drive assets for $2bn (£1.3bn) in June. The deal is expected to close at the end of this year.
