3ware 9000 Series Serial ATA RAID Controller User Guide

Figure 2). This gives your system fault tolerance by preserving the data on 
one drive if the other drive fails. Fault tolerance is a basic requirement for 
mission critical systems like web and database servers.

3ware uses a patented technology, TwinStor®, on RAID 1 arrays for 
improved performance during sequential read operations. With TwinStor 
technology, read performance is twice the speed of a single drive during 
sequential read operation.

The adaptive algorithms in TwinStor technology boost performance by 
distinguishing between random and sequential read requests. For the 
sequential requests generated when accessing large files, both drives are used, 
with the heads simultaneously reading alternating sections of the file. For the 
smaller random transactions, the data is read from a single optimal drive head. 

 

Figure 2.   RAID 1 Configuration Example

RAID 5

Combines striping data with parity (exclusive OR) to restore data in case of a 
drive failure. This array type provides performance, fault tolerance, high 
capacity, and storage efficiency. Requires a minimum of three drives. 

Parity information is distributed across all drives rather than being 
concentrated on a single disk (see Figure 3). This avoids throughput loss due 
to contention for the parity drive.

Figure 3.   RAID 5 Configuration Example

RAID 10

This array is a combination of RAID 1 with RAID 0. Striped and mirrored 
arrays for fault tolerance and high performance. Requires a minimum of four 
drives to use both RAID 0 and RAID 1 techniques.
