In RAID applications, the most commonly selected option is a RAID control card (some server motherboards already integrate a RAID controller, making it unnecessary to purchase an additional RAID control card). Through this card, various high-performance data storage and redundancy can be achieved. A RAID control card is essentially a disk array card, with its core being the RAID control chip. With the development of RAID technology, today's RAID control cards are no longer limited to providing only SCSI disk interfaces. The commonly used IDE and SATA interfaces in PCs now fully support RAID technology as well, especially in mid-to-low-end disk arrays. In particular, the emerging SATA interface RAID control cards are widely used.
The ADAPTEC SCSI-3210S disk array card has 2 internal 68-pin and 2 external 68-pin SCSI interfaces, allowing for the connection of up to 30 SCSI disks or SCSI peripherals. The RocketRAID 404 disk array card provides 4 independent IDE channels. Since one IDE interface can connect to a maximum of 2 disks, it can connect up to 8 IDE disks. The HIGHPOINT company offers the RocketRAID 1640 disk array card that supports 4 Serial ATA (SATA) channels. The RocketRAID 1640 can connect up to 4 disks, with data transfer rates reaching up to 150 Gb/s. It supports RAID 0, 1, 0/1, 1/0, 5, and JBOD.
SATA interfaces are not only available internally; some RAID control cards also provide external SATA interfaces. The HIGHPOINT company’s ROCKETRAID 1542 RAID control card is a product that supports 4 Serial ATA (SATA) channels, two of which are external SATA interfaces.
