1.IDE (Integrated drive Electronics, electronic integrated drives), more common. The IDE hard drive has the following three types of transmission modes: PIO (programmed I/O) mode, DMA (driect Memory Access) mode, Ultra DMA (short UDMA) mode.2.SCSI (Small computer system Interface, small computer system interface), is a completely different interface with the IDE (ATA), the IDE interface is the standard interface of the ordinary PC, and SCSI is not spe

replication, replay, and other attacks.9.2 Hacker attacks on devices1. Bypassing ATA Password securityATA is a common security measure in a company that protects stolen notebooks from being accessed illegally. The ATA security mechanism requires the user to enter a password before the BIOS reads the hard drive.The simplest approach is to hot-plug the hard disk into a system that disables the

computers, the data stored by users often far exceeds the computer's own price. When the cost is relatively small, RAID technology can enable individual users to enjoy doubled disk speed and higher data security, the IDE-RAID control chips on the PC market are mainly from highpoint and promise, and some are from AMI companies (such as table 2 ). IDE-RAID chips for individual users generally only support RAID 0, RAID 1 and RAID 0 + 1 (RAID 10) raid specifications, although they are technically i

SASAndSATAHard Disk differences As you know, like ata, SCSI is a parallel technology that can connect multiple devices through their respective data channels. Like ata, SCSI is also evolving towards Serial technology, which is SAS (Serial Attached SCSI ).In short, SAS is a new generation of SCSI, which includes some improvements, such as higher transmission speed, better scalability and reliability. Some pe

the 64-bit bus can transmit 64 bit data at the same time. each bus has a clock measured in MHz. this data transmission rate at the end-to-end of the bus affects the speed at which the application runs. Bus can be divided into the following types based on the channels in the computer system: System Bus: This bus transfers data from CPU to memory. Local or I/O Bus: a high-speed path directly connected to the processor, responsible for communication during the peripheral device and pr
