Introduction to IDE, SATA, SCSI, SAS, FC, SSD drive types [ZZ]

low, but the speed is slow. Each MLC unit is 2bit, a whole lot more than the SLC. However, due to the large number of data stored in each MLC storage unit, the structure is relatively complex, the probability of error will increase and must be corrected, this action causes its performance significantly lag behind the structure of the simple SLC flash memory. In addition, the advantage of SLC flash memory is up to 100,000 times, 10 times times higher than MLC Flash. In addition, in order to ensu

Introduction to IDE, SATA, SCSI, SAS, FC, SSD drive types

Reference: http://blog.csdn.net/tianlesoftware/article/details/6009110The main types of hard disk interfaces currently available are IDE, SATA, SCSI, SAS, FC, and so on.The IDE is commonly known as the port, SATA is commonly known as the serial port, both of the hard disk is the PC and low-end server common hard disk.SCSI is the abbreviation for "Small computer system dedicated interface", which is the hard disk with this interface.SAS is the

Install Windows 2000 on a SCSI hard drive

Many people are not unfamiliar with the installation of Windows 2000, and it is true that there is no difficulty in performing Windows 2000 Setup.exe, upgrades, or direct installations from Windows 98, for the vast majority of users who use IDE hard disks. However, if your computer is a graphics workstation using a SCSI hard drive, it might be a different story. My Computer is a typical example,

compatible with the PATA device by using a multi-purpose chipset or serial-parallel converter. Because SATA and PATA can use the same drive, you do not need to upgrade the operating system or perform other changes. 5. You do not need to set the jumper of the Master/Slave disk for Sata. The BIOS will number it in the order of 1, 2, and 3. This depends on the SATA connector to which the drive is connected

Solaris: Configuring a SCSI tape drive on the enterprise server

Not every place running Solaris operating System has the resources to backup the solution, and they don't even need those resources, such as expensive tape-changer, tape library, or Tape Silo. What is usually needed is a backup or ufsdump of the root file system, an important database, or a small development entry code. In these cases, external devices such as SCSI DDS tape drives are usually sufficient. The following information is useful for config
