Maxtor's ATA-133 Does 160GB
B. Galliart writes "ExtremeTech has an article about Maxtor's two new bleeding edge ATA-133 drive models coming out later this month. The most interesting of these is the 160 Gigabyte DiamondMax Plus D540X (priced around $400) which uses Maxtor's purposed "BigDrive" 48-bit address space instead of the common E/IDE 28-bit address space thus getting pass the 137GB barrier. The drive should be useable on existing computers due to a bundled Promise Technologies ATA-133 PCI card."
For most of the applications the rotation speed is more important than the ATA standard. This determines the access time.
I prefer an ATA-66 @ 7200 rpm above an ATA-100 @ 5400
The nice thing about Windows is: it does not just crash; it displays a nice little dialog box and let's you press 'OK'
ATAPI still has a limit of 2 devices (master/slave) per controller. Ultra-SCSI is 15, not including LUNs.
ATAPI devices are still limited to hard drives and CD-ROMs (via a hack). SCSI handles scanners, tape drives and other devices as well -- it is much more generic.
ATAPI still causes performance degredation when you are accessing the master and slave on the same channel at the same time. SCSI does not.
Learning HOW to think is more important than learning WHAT to think.
How quickly do we forget that CPRM proposal was defeated and Maxtor was one of the high-profile companies to vote against it. IBM, Microsoft, Iomega and others wanted to push it through.

If you think big enough, you'll never have to do it.
Maxtor's so called Big Drive technology is no more than an implementation of the spec. ATA/ATAPI-6 specifies a 48 bit address scheme, giving a new upper limit of 2^48*512 bytes, or 128 petabytes.
Also, the limitation is not 137 GB, it's 128 GB. And Maxtor's new drives are not 160 GB, they're slightly more than 149 GB. These mistakes are what happen when you start believing "drive manufacturer math".
