PATA和SATA的区别PATA: PATA 代表 Parallel Advanced Technology Attachment,它是一种总线接口,用于连接硬盘、光驱等辅助存储设备。它于 1986 年由 Western Digital 和 Compaq 首次推出。后来被SATA取代。SATA: SATA代表Serial Advanced Technology Attachment,是一种连接硬盘、光驱的总线接口。它于 2001 年在 PATA 被...
以下大部分内容源于differencebetween,根据自己的理解整理而成。 AHCIvsATA ATA(AT Attachment)是一个很久远的标准,最初是定义诸如硬盘等存储设备和CPU的接的标准。一共有两种类型的ATA,第一种叫ParallelATA(PATA),第二种叫SerialATA(SATA),现在使用ATA这个词汇默认是指前者,也就是PATA,他是在SATA之前出现的。而...
Besides the number of rotations per minute the other main difference was that SCSI drives were faster because of added intelligence called Command Queueing (CQ). SCSI drives were able to change the order of IOs so the drive’s arms didn’t have to cross the whole surface to reach each bloc...
Basic design.SATA connectors have four wires in one cable. SAS connectors also have four wires, but they separate the wires into two cables where each conductor pair can send and receive data. Because of this difference, SATA can only connect a motherboard to a storage device. SAS, on the...

A serial advanced technology attachment (serial ATA, SATA or S-ATA) is a computer bus interface used to connect host bus adapters with mass storage devices like optical drives and hard drives. This interface is commonly used to connect hard disk drives to a host system such as a computer mo...
So, for those of us still mucking around with pre-SATA, I'm wondering... is there an appreciable difference between ATA-100 and ATA-133, assuming the same rotational speed (e.g. 7200rpm)? Or is it so slight as to be negligible? Dusty Egghead Posts: 3,396 I could if she would,...
I've succeed in sending ATA command to SATA drive ( device \\.\PhysicalDrive3 ) with iotcl command IOCTL_ATA_PASS_THROUGH_DIRECT .(device identified as an SCSI device )Now I would like to send ATA command to the same disk connected to USB port thanks to an USB/SATA Adapter ....
The difference between queued and non-queued commands is what happens after the command is issued. If a non-queued command was issued, the drive would transfer the data for that command and then clear the BSY bit in the Status register to tell the host that the command was completed. When...
AHCI (Advanced Host Controller Interface) is a modern interface standard that enables advanced features in SATA drives, while ATA (AT Attachment) is an older interface standard used for connecting storage devices in computers. Difference Between AHCI and ATA ...
