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...

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 ....
So if you want the option to "scrub" your boot drive, then your going to want to go with a SATA hard drive and not a SSD. Also you want a MBP other than the MacBook Pro-Retina, so that you can open the machine and remove the internal storage for destruction. How do I securely...
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...
存储基础:ATA、SATA、SCSI、SAS、FC 按照接口类型我们可以分为ATA、STATA、SCSI、SAS、FC,接下来我们分别就以上几种接口类型进行一些对比。...ATA 发展至今经过多次修改和升级,每新一代的接口都建立在前一代标准之上,并保持着向后兼容性。...到目前为止,一共推出 7 个版本: ATA-1 、 ATA-2 、 ATA-3 、...
