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 offers the most compre-
hensive line of PCI Express controllers, available 
in both low profile and full height footprints 
with 2, 4, 8, 12, 16, and 24-port configurations. 
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, significantly 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 traffic travel 
through just one cable, significantly 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, airflow 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.
