The power supply is called the power cable, and the motherboard is called the data cable. . .

Anonymous users2024-02-09Distinction between pata and sata.
The full name of PATA is Parallelata, which is the parallel ATA hard disk interface specification, which is the most common hard disk interface specification now. The size of the PATA hard disk interface has a very glorious history, and it has developed from ATA33 66 to ATA100 133 to the highest ATA150 today. The full name of SATA hard disk is Serialata, that is, Serial ATA hard disk interface specification.
At present, the typical write speed of the PATA100 hard drive is 65MB s, while the first generation SATA hard drive has a write speed of 150MB s, and the second generation SATA hard drive has a write speed of up to 300MB s, which is exactly twice the speed of the first generation. The emergence of the SATA hard disk interface specification is actually to replace PATA, just like DDR replaces SDRAM.
From a technical point of view: how much faster SATA is than PATA?
Since the emergence of SATA is to replace PATA, where are the main advantages of SATA compared with PATA? The first is speed, as we mentioned above that the transfer speed of the second-generation SATA is 300MB s, but the transfer speed of the third-generation SATA products has been increased to 600MB s. In terms of speed, SATA has left the PATA hard drive far behind.
In addition, SATA is also superior to PATA in terms of transmission mode. SATA uses single-channel transmission, and PATA uses multi-channel transmission. Some friends may literally mistakenly think that PATA's multi-channel should be faster than SATA's single-channel, but it is not.
This is because SATA's single data channel does not limit the speed frequency like PATA. SATA transmission lines are nearly 30 times faster than PATA. PATA must transmit 16 signals at a time in the data line, and if the signal does not arrive in time or is delayed, error data will occur.
As a result, the speed of bitstream transmission had to be slowed down to correct the error. SATA, on the other hand, only transmits one bit of data at a time, and the bitstream is delivered much faster. It's like a game of dribbling, and it's much easier to dribble one ball at a time than 16 balls at a time.
In addition, another improvement of SATA is its data cable, which is smaller in size, has better heat dissipation, and is quite convenient to connect to hard drives. SATA consumes less power than PATA, which is good news for laptops, while the unique CRC technology makes data transfer more secure.

Anonymous users2024-02-08Different motherboards have different settings methods.
There are usually two items.
The first is to set up IDE and SATA to work together.
Second, set the boot order of the hard disk. If the first item is not set properly, the corresponding hard disk will not be found in the second item.
Let's take the most common ICH6 7 as an example.
In the SATA Devices Configuration in Integrated Peripherals, the ATA IDE Configuration can be set in mode. It is recommended to set it to compatibility mode.
When set to compatible mode, only 4 devices can be used, and there are four options for configuring sata as:
SATA ONLY: Only SATA interfaces are used, but 4 SATA ports can be used to connect 4 SATA hard disks.
PATA PRI, SATA SEC:IDE is the primary channel to connect two SATA devices, SATA is the secondary channel, and only SATA2 and 4 can be used to connect two SATA hard disks. zrzj
SATA PRI, Pata SEC: SATA is the main channel, and only SATA 1 and 3 can be used to connect 2 SATA hard disks. IDE1 does the secondary channel to connect the two PATA devices. v`p6g
pata only: uses only IDE interfaces and does not use SATA interfaces.
When set to Enhanced mode, you can connect up to 6 devices using IDE1 and SATA. At the same time, you can configure SATA AS with the following three options:
IDE mode, IDE interface and 4 SATA interfaces use IDE mode at the same time, IDE mode uses IO transmission.
AHCI]: AHCI mode, the IDE interface and 4 SATA interfaces use AHCI mode at the same time, AHCI mode provides a connection bridge between memory and SATA devices, it includes new technologies such as native command queue (NCQ), hot swap, power management, etc.
RAID]: RAID mode, that is, to form a disk array, ICH6R supports soft RAID 0 and 1.
The latter two are ICH with R, which is only available if RAID is supported. If you don't have R, there is only one IDE.
After this is set up. In the order in which the hard disk is booted, you can choose which hard disk to boot from.
