RZ26L High Performance, Low Profile 1.05 GB Disk Drive
HIGHLIGHTS
o New SCSI disk offered in one-inch-high, 3.5 inch form factor
o 15 percent price/performance improvement over RZ26 disk
o Features new, five year warranty
PRODUCT DESCRIPTION
To meet the need for follow-on products in the same capacity range as
Digital's RZ26 and RZ26B 1.05 Gbyte disk drives, Digital is introducing the
RZ26L drive. This one-inch-high, low profile SCSI disk expands the
performance and price/megabyte curves of the previous generation of Digital
3.5 inch disks. In addition, its state-of-the-art seek and access times and
industry standard spindle speed make it Digital's highest performing
3.5 inch SCSI disk today. The banding technology used provides maximum
transfer rates (in the 3.5 inch form factor) of up to 5.5 Mbytes per second.
The RZ26L disk comes with a five year warranty (one year of onsite warranty
and four years of extended, Return-to-Digital warranty), demonstrating
Digital's higher quality standards and enhanced maintainability standards.
(See the "Enhanced Storage Warranties Span Up to Five Years" article in this
issue.)
Note that the RZ26L drive is not a direct substitute for the RZ26 drive in
all applications. The RZ26L drive cannot be placed in an existing RZ26
stripe and/or shadow set. However, a new stripe and/or shadow set can be
created when all members are RZ26L disk drives.
