), Ataz Chinese hard disk interface technology, SATA, is Serial ATA, a new type of hard disk interface completely different from parallel ATA, named because of the serial transmission of data. SATA 1.5gbit/s, SATA 3gbit/s, and SATA 6gbit/s are now available in three different sizes.SAS (Serial attached SCSI), serial-attached SCSI, is a new generation of SCSI technology that is the same as the current popula
up.In order to prevent change, just a copy of the data two copies, this technology is mirrored mirror. Another technique is the cyclic redundancy check code (RAID4), which is not used to store data on the disk, but the check code on this disk, when one of the bad, the use of checksums and other disk data to recover the data on the broken disk, so that the disk utilization is good, But a two-piece hard drive would have been a terrible break. A rich enterprise, two technology combined.Because eac
1. Run msconfig command
Open the Windows 7 Start menu in the lower-left corner of the screen, type msconfig in the search box, press ENTER, and start the Windows 7 System Setup interface.

2. Modify Startup settings
The Open System settings interface has five tabs at the top, first open the Boot tab, modify the timeout (timeout) to 3 seconds (min 3 seconds), and then select the No GUI boot (no GUI booting) option.
3. Set the number of boot CPUs

How do I install hard drive (AHCI)?
Tell users what AHCI is and how to install AHCI drivers
VISTA WIN7 and WIN8 installation AHCI is more convenient if installing XP requires some action to install AHCI hard drive
First, AHCI Introduction:
AHCI, called Serial ATA Advanced Host Controller Interface (serial ATA Advanced Master Interface), is an interface standard developed by several companies under Intel
I've always felt like my computer is getting slower lately. So want to optimize, but the General software optimization has reached the limit, the streamlining system is not my style. So I began to look for problems like hardware. So I found a good thing--ahci.AHCI (Serial ATA Advanced host Controller Interface) serial ATA Advanced Master interface/Advanced Host Controller Interface) is an interface standard
Sata
SATA (serial Advanced Technology attachment) is the abbreviation for Serial ATA, which is currently available SATA-1 and SATA-2 two standards, the corresponding transmission speed is 150mb/s and 300mb/s. SATA is primarily used for PATA interface technology that has replaced bottlenecks. From the speed of this point, SATA in the transmission mode SATA is also more advanced than Pata, has been far away from the PATA hard drive behind. Second, from

-q,–quietSuppresses display and returns only the exit status. 0 indicates that a matching row was found.
-l,–files-with-matchesPrint a list of files that match the template.
-l,–files-without-matchPrint a list of files that do not match the template.
-n,–line-numberPrint the line number before the matching line.

disk is mainly used in middle and high-end servers, high-end workstations and storage devices.
The SCSI interface is currently used with 68-pin and 80-pin interface specifications.
The SCSI interface is a parallel transport interface.
To emphasize, SCSI this kind of hard disk basically already eliminated, use very few similar to SATA replace Pata, SCSI also must be replaced by its upgrade product SAS (serial attached SCSI).

The SAS English name is serial attached SCSI or

the device is not much. Printers and scanners that use LPT interfaces are rarely available, mostly for printers and scanners that use USB interfaces.
MIDI interface: The MIDI interface of the sound card and the joystick interface are shared. The two pins in the interface are used to send MIDI signals and can be connected to a variety of MIDI devices, such as electronic keyboards, and it is difficult to find products based on this interface in the market.
