The Best Keeps Getting Better
The 3ware 9650SE PCI Express to SATA II RAID
controller pushes LSI established leadership in
RAID controller performance to new heights.
While 3ware controllers continue to lead the
market in RAID 5 performance, the 3ware
9650SE outshines the competition as the
new standard bearer for RAID 6 performance,
delivering over 700MB/s RAID 6 reads and
600MB/s RAID 6 writes.
The 3ware 9650SE oers the most compre-
hensive line of PCI Express controllers, available
in both low prole and full height footprints
with 2, 4, 8, 12, 16, and 24-port congurations.
All 4-port and above models feature 3ware’s
award-winning Multi-lane connectivity. The
9650SE supports RAID levels 0, 1, 5, 6, 10, 50,
Single Disk, and JBOD.
Red Hot RAID 6
RAID 6 eliminates the risk of data loss if a
second hard disk drive fails while the RAID array
is rebuilding. In a 3ware RAID 6 system, two
sets of parity are simultaneously calculated,
written, and rotated across all the drives. This
second parity calculation enables the array to
survive up to two drive failures without losing
data, signicantly improving fault tolerance.
The 3ware parallel XOR RAID 6 parity generation
algorithm maximizes RAID 6 throughput, so
that RAID 6 enabled 9650SE controllers deliver
unequaled RAID 6 performance.
Get Connected via the
Multi-lane Expressway
3ware’s award winning Multi-lane high band-
width SATA connection system is fast, secure,
simple, and clutter free. Multi-lane combines
four SATA ports into a single locked connection.
Four lanes of high speed SATA trac travel
through just one cable, signicantly reducing
the number of cables needed to connect
controllers, backplanes, and standard SATA
drives. A 16-port Multi-lane controller needs
only four cables, compared to sixteen cables
with discrete solutions, for dramatically better
reliability, airow and convenience.
Enterprise-class RAID Storage
The 9650SE’s advanced RAID features, SATA II
connectivity, and powerful 3ware performance
architecture make it the ideal controller for
vertical applications that require the highest
levels of sustained write and read performance
including NAS storage, web servers, cluster
servers, supercomputing, near-line backup and
archival, security systems, pro audio and video
applications, and other demanding storage
applications that need high-bandwidth, high-
capacity sequential performance.
LSI 3ware 9650SE SATA II hardware RAID controllers deliver industry-
leading RAID 6 and RAID 5 performance, robust fault tolerance, and
multi-terabyte capacities. A PCI Express host interface, Multi-lane™
connectivity, StorSwitch™ architecture, and sophisticated SATA II features
drive this unrivaled performance.

RAID 6: Two sets of parity data, P + Q, are
striped across disks. RAID 6 safeguards against
data loss during rebuild mode by allowing up
to two consecutive drive failures for maximum
fault tolerance.
