StorageReview has posted a review on the Maxtor Atlas 10k III harddisk
As nomenclature suggests, the Atlas 10k III represents the third iteration the venerable Quantum performance line. In addition to its 10,000 RPM spindle speed, the 10k III features a contemporary 18 gigabytes per platter. The flagship model, reviewed here, combines four of these disks to yield 73 GB of capacity. Maxtor specifies seek times at a svelte 4.5 milliseconds, the lowest yet claimed for a 10k RPM drive. The 10k III maintains the spacious 8-megabyte buffer debuted by its predecessor.Read more
The Atlas 10k III unit reviewed here features an Ultra160 interface. Maxtor plans to ship Ultra160 and eventually Ultra320 versions of the drive. The performance differences yielded by the Ultra320 version should be negligible in all cases excepting only huge multi-drive arrays servicing applications that require high transfer rates. A single 10k III won´t come close to saturating Ultra160.
