SATA, all of the name is Serial ATA, which is when using the serial ATA interface, due to capabilities like strong anti-interference performance, plus the requirement of entire data lines is much less than ATA, support hot swap and the like, final results of SATA-II interface is 375MB / s, while the transfer speed of the latest SATA-III criteria can reach 750MB / s. SATA data cable is also much thinner than the ATA, is conducive towards the venting in the event, is additionally useful to organize the wire.

Compared with the driving voltage of Parallel ATA, 0.5V SATA system spend less power, as well as the fabricating cost of its drive IC will be less.

FATA  hard drive is often a hybrid hard disk technology, called fiber subsidiary adapter (FATA, Fibre Attached Technology Adapted). Fractional treatments was jointly developed using the largest disc drive manufacturer Seagate, that may effectively reduce the cost of the hard disk, in order that contribute to improve the cost performance of disk arrays.

The most selling point of FATA  hard drive is the fact it might mixed use FC hard disk drives and FATA hard disk drives in the same disk, the inadequacy could be the valuation on FC interface is slightly expensive than SATA hard drive  interface, in support of Seagate and Hitachi master FC interface technology among the harddrive vendors. The sources of hard drives are limited—frankly, using FATA hard disks is single. Supplier is difficult to create it in quantity--further raise the tariff of the FATA. Moreover, for the time being, perhaps the EVA products use hard disk drive FATA, it really is rarely to see a disk ark inside adopt FC and FATA hard disk drives within the same time.

The English name of SCSI is "Small Computer System Interface" (Small Computer System Interface), takes a different approach from IDE (ATA) interface completely. IDE interface will be the standard interface of general PC, while SCSI seriously isn't an interface created for the hard disks, is usually a high-speed data transmission technology widespread on minicomputers. SCSI hard drive interface is loaded with lots of advantages like wide range of applications, multitasking, large bandwidth, low CPU occupancy rate, and also hot swapping etc. However, it is hard to popularize like IDE hard drives due to the higher price. Thus, SCSI hard drive mostly are used in high-end servers and high-end workstations.

After several generations of development, from early SCSI-II, to the present Ultra320 SCSI and Fiber-Channel (FC), sort of interface also varied. SCSI computer drives are popular on workstation-class PC and servers, therefore, it is going to adopt higher technologies, for instance high-speed disc rotation speed 15000rpm reducing CPU occupancy rate when data is transfer, nevertheless the unit costs are costlier as opposed to same capacity of ATA and SATA hard drive.

SAS (Serial Attached SCSI) is usually a new generation of SCSI technology. Same goes with SATA hard drives, it adopt sequential technology to buy higher transmission speeds, it could reach 6Gb / s. In addition, furthermore , it improves the interior space system with the narrow connecting line.

Besides, because of SAS hard disk drive can share the identical backplane with SATA, so from the same storage system, you can use SATA hard disks to replace some expensive SAS hard drives just to save overall storage costs. But SATA storage system cannot connect SAS drives.

SAS is a new interface after developing the parallel SCSI interface. This interface is made to improve performance, availability and scalability of storage systems, and offer compatibility while using SATA harddrive.

FC (Fibre Channel, Fibre Channel interface), featuring on hot-swap, high-speed bandwidth (4Gb / s or 10Gb / s), remote connection and many others when such hard disk drive interface using fiber-optic connections; internal transfer rate is more than ordinary hard disk drives. Limited using its high price, it generally use on the high-end servers. Like SCSI interfaces, FC hard drive isn't an interface technology designed originally for your hard disk drive, is made for network system, however with final results dependence on storage system, it gradually given to the hard disk system. FC hard drive  is designed for increasing the speed and flexibility of multi-drive storage system, it seems greatly improved the communication speed of multi-drive systems. The main characteristics of Fibre Channel are: hot-swapping, high bandwidth, remote access, many connecting equipment.

Fibre Channel is ideal for multi-drive system environments such as servers, it can meet requirements of data transmission rate including the high-end workstations, servers, mass storage sub-networks, peripherals bidirectional serial data communications systems for high-hubs, switches and connected by point and many others.
