ATI controller RAID Driver

This implementation resulted in excessive CPU utilization which largely negated the advantages of command queuing.


By contrast, overlapped and ATI controller RAID operations have been common in other storage buses; in particular, SCSI's version of tagged command queuing had no need to be compatible with APIs designed for ISA, allowing it to attain high performance with low overhead on buses which supported first party DMA like PCI. This has ATI controller RAID been seen as a major advantage of SCSI.

The Serial ATA standard has supported native command queueing NCQ since its first release, but it is an optional feature for both host adapters and target devices. There are ATI controller RAID debates about how much a slow device can impact the performance of a faster device on the same cable.

There is an effect, but the debate is confused by the blurring of two quite different causes, called here "Lowest speed" and "One operation ATI controller RAID a time". On early ATA host adapters, both devices' data transfers can be constrained to the speed of the slower device, if two devices of different ATI controller RAID capabilities are on the same cable. This allows each device on the cable to transfer data at its own best speed.

Even with earlier adapters, without independent timing, this effect applies only to the data transfer phase of a read or write operation. This is caused by the omission of both overlapped and queued feature sets from most parallel ATA products. Only ATI controller RAID device on a cable can perform a ATI controller RAID or write operation at one time; therefore, a fast device on the same cable as a slow device under heavy use will find it has to wait for the slow device to complete its task first.

However, most modern devices will report write operations ATI controller RAID complete once the data is stored in their onboard cache memory, before the data is written to the slow magnetic storage. This allows commands to be sent to the other device on the cable, reducing the impact of the "one operation at a time" limit.

The impact of this on a system's performance depends on the application. For example, when copying data from an optical drive to a hard drive such as during software installationthis effect probably will not matter. Such jobs are necessarily limited by the speed of the optical drive ATI controller RAID matter where it is.

But if the hard drive in question is also expected to provide good throughput for other tasks at the same time, it probably should not be on the same cable as the optical drive. ATA devices may ATI controller RAID an optional security feature which is defined in an ATA specification, and thus not specific to any brand or device. The security feature can be enabled and disabled by sending special ATA commands to the ATI controller RAID.

If a device is locked, it will refuse all access until it is unlocked. A device can have two passwords: A ATI controller RAID Password and a Master Password; either or both may be set.

There is a Master Password identifier feature which, if supported and used, can identify without disclosing ATI controller RAID current Master Password. A device can be locked in two modes: High security mode or Maximum security mode.

There is an attempt limit, normally set to 5, after which the disk must be ATI controller RAID cycled or hard-reset before unlocking can be attempted again. In Maximum security mode, the device can be unlocked only with the User password. While the ATA lock is intended to be impossible to defeat without a valid password, there are purported workarounds to unlock a device.


Due to a short ATI controller RAID length specification and shielding ATI controller RAID it is extremely uncommon to find external PATA devices that directly use PATA for connection to a computer. A device connected externally needs additional cable length to form a U-shaped bend so that the external device may be placed alongside, or on top of the computer case, and the standard cable length is too short to permit this.


For ease of reach from motherboard to device, the connectors tend to be positioned towards the front edge of motherboards, for connection to devices protruding from the front of the computer case. This front-edge position makes extension out the back to an external device even more difficult. Ribbon cables are poorly shielded, and the standard ATI controller RAID upon the cabling to be installed inside a shielded computer ATI controller RAID to meet RF emissions limits.

External hard disk drives or optical disk drives that have an internal PATA interface, use some other interface technology to bridge the distance between the external device and the ATI controller RAID. This was last published in June Load More View All.
