interface (atapi ). Original ide drives were unable to handle drive sizes larzger than 528 MB due to their use of the cylinders, Head, and sectors (CHS) method of addressing space. eide drives use Logical Block Addressing (LBA) that allows a hard drive's sectors to appear to the OS as one long sequence of data with a concurrent address for each sector. typically, when referring to an Eide drive, the "e" is assumed and not mentioned. The current ide drive standard is the ATA 100 interface tha

using RAID and using SCSI hard disks? Which one is more cost-effective?A: Here we only discuss the IDE-RAID. In general, SCSI can provide better stability and faster speed, but the price is quite expensive. The price of a 7200-to-9.2 GB/Ultra160 SCSI hard drive will be as high as about 1500 yuan. In contrast, the general IDE hard drive capacity at the same price will be more than 80 GB.We can compare IDE-RAID and scsi raid, we use four Maxtor golden

Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. Currently, many open-source cross-platform software are available, which makes the performance of Linux and Windows software comparable. The performance of the software in Ubuntu 8.04 and Windows XP SP3 is compared by Hammed Saleh. The test
