I. Use the hdparm commandThis is a command used to obtain the parameters of the ATA/IDE hard disk, hdparm has been written by Mark Lord, the primary developer and maintainer of the (E) IDE driver for Linux, with suggestions from javasnetfolk ). this command should also be used only for Linux systems. For UNIX systems, ATA/IDE Hard Disks may be used less often. Generally, large systems use disk arrays.Easy t
priority is higher than the static priority.Linux supports three types of internal scheduling:Real-time processes support two types of scheduling:1. SCHED_FIFO: first in first out2. SCHED_RR: round robinFF-type processes are called through SCHED_FIFO; RR-type processes are called through SCHED_RR.A user process supports one type of scheduling:1. SCHED_OTHEROS-type processes are called through SCHED_OTHER.So how can I view the information used by the current operating system process? You can use

Test disk read/write IO speed
Sometimes, during maintenance, we always encounter a problem similar to IO, but it cannot be determined whether it is an I/O bottleneck or a hot disk caused by improper configuration of software parameters. at this time, we usually want to know the read/write speed of the disk for further decision-making.
The following are two test methods:(1) Us

At present, all hard disks on the market have S. m.A. r. t. (Self-Monitoring, Analysis and Reporting Technology), smartmontools is a software package that uses this feature to monitor hard disks, including smartctl and smartd, the former is the front-end command line tool, and the latter is the background running program. smartmontools is not a Linux patent

), 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

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.

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

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).
