A SATA2 question, please come in and take a look

Ordinary XP disk can be installed, I am SATA2 hard disk without floppy drive.

After installation, it can only recognize 137G hard disk, and then install the main driver to 160G full recognition.

Reformatting the last partition will bring back the unrecognized space.

Install it with the system installation disk.,No problem.,My one without a floppy drive can be installed.。

Where do you go to buy a tomato garden, come back for 5 yuan, and then install your ordinary XP system disk after installation.

Use the Tomato Garden version of it, which has an XP with SATA driver on it

No, the differences are as follows:

1. Appearance difference:

The SATA1, SATA2, and SATA3 BAI-based interfaces are the same on the motherboard. However, in order to distinguish between SATA2 and SATA3 hard drive interfaces.

Many motherboards are often marked with different colors. Most motherboards that support the SATA2 interface are black, while the SATA3 interface is yellow, white, blue, etc.

The hard drive SATA2 interface and SATA3 motherboards are basically the same appearance, and many low and medium motherboards still use SATA2 and SATA3 dual interface mixed mode, like the A75AMD platform, Intel.

Platform B75H81, B85 motherboard SATA2 and SATA3 dual interface mixed mode, and some mid-to-high-end motherboards, such as A88H87Z87 motherboard are interfaces.

2. Difference in transmission speed:

The transmission rate of the SATA3 interface is different from that of the SATA2 interface. The latest SATA3 interface can reach 6GB s, while SATA2 interface can reach 3GB s. Theoretically, the interface is twice as large. SATA1 is the slowest.

3. Differences in compatibility:

Interfaces are compatible with interfaces and interfaces, and interfaces are compatible with interfaces. However, the interface is not compatible with the interface and the interface, and the interface is not compatible with the interface.

and the interface types are compatible and universal. In fact, belonging to the next generation of upgrades, it is fully compatible. Just like the relationship between and, the two are compatible with each other.

1. Appearance.

The SATA1, SATA2 and SATA3 ports on motherboards are basically the same, but many motherboards are often marked with different colors in order to distinguish the SATA2 and SATA3 hard drive interfaces. Most motherboards that support the SATA3 interface are black, while the SATA3 interface is yellow, white, blue, etc.

SATA2 and SATA3 motherboards still use SATA 2 and SATA 3 dual-interface hybrid mode in many low-end motherboards, such as AMD platform A75, Intel platform B75, H81, B85 motherboards are SATA 2 and SATA 3 dual-interface mixed mode, and some mid-to-high-end motherboards, such as A88, H87, Z87 and other motherboards are all interfaces.

2. Transmission rate.

The latest SATA3 interface can transmit 6 GB s, while the SATA2 interface has a transmission rate of 3 GBS. Theoretically, the interface is twice as much. SATA1 is the slowest.

3.Compatibility is different.

The SATA interface can be compatible with SATA interfaces and SATA interfaces, and SATA interfaces can be compatible with SATA interfaces. However, SATA interfaces are not compatible with SATA interfaces and SATA interfaces, and SATA interfaces are not compatible with SATA interfaces.

In fact, SATA belongs to the next generation of SATA upgrade, and it is fully compatible with each other, just like the relationship, the two are compatible with each other.

Extended Materials. Getting the best read speed out of your drive depends not only on the drive, but also on the drive interface. That is to say, as long as the hard disk supports the SATA interface and is connected to the motherboard that supports the SATA interface, the hard disk of the computer will play the best performance, so some old computer hard disks only support SATA2 at most, even if this kind of hard disk is connected to the SATA 3 motherboard, the speed is still SATA2 speed, because the hard disk itself is hard to bruise.

Similarly, if the hard disk supports it, but the motherboard only has an interface, then the actual speed of the hard disk is only the speed of SATA2, which needs to be paid special attention to and must meet the conditions at the same time. Like the current mainstream mechanical hard disk and SSD are interfaces, especially solid-state hard disks are interfaces, users only need to choose the motherboard that supports the interface when installing and choosing SSD. 11

SATA3 has the same interface as SATA2 and SATA1, which belongs to the next generation upgrade of SATA2, and is fully compatible with each other. The difference is that SATA3 and SATA2 have different transfer rates, the latest SATA3 transfer rate can reach 6GB S, while the SATA2 interface has a transfer rate of 3GB S. Theoretically, the interface is twice as much.

Differences between SATA2 and SATA3 interfaces:

1. From the appearance alone, the SATA3 and SATA2 interfaces on the motherboard are basically identical, but many motherboards are often marked with different colors in order to distinguish the SATA2 and SATA3 hard disk interfaces for users. Most motherboards that support the interface SATA2 connector are black, while the SATA3 connector color is yellow, white, blue, etc.

The interface is the same and fits. SATA3 is backwards compatible with SATA2 and SATA1.

That is to say, if you have the SATA2 interface on the motherboard, you can buy a SATA2 hard disk, even if you use a SATA3 hard disk, the speed is still SATA2.

If you buy the LegWiden sate3 expansion card, this must be the same, and the products of LegExpand are the latest according to the needs of users. Friends use this brand, I hope it can help you.

The interface is basically the same.

However, the hard disk of the Legot SATA3 expansion card is connected to the interface of SATA1, the speed is the same as the speed of SATA1, and the speed of SATA2 is also the speed of SATA2, I hope it can help you.

It doesn't matter, and the difference between the two is barely felt.

The speed of the hard disk is generally divided into two types: the burst transfer rate and the internal transfer rate, bursting refers to the speed between the hard disk cache and the computer system, which varies greatly between SATA2 and 3, but it is rarely the case in practical applications: that is, the task can be completed by reading the hard disk cache directly, so this indicator is basically not very useful.

The internal transfer rate refers to the speed at which the head of the hard disk can read and write the platter, which is the most important. When you boot or run the software, you can pay attention to the movement of the hard disk, which is to read data from the platter, so this indicator is also the most direct experience. Although the development of mechanical hard disks is much faster than before, the transfer speed still does not exceed the upper limit of SATA2, so it is the hard disk itself that limits the speed rather than the interface.

Just like a car can't even run 80 kilometers, is there a difference between a speed limit of 100 and a speed limit of 200?

If the SSD is different, the read and write speed is 3, 400M or even 5, 600M per second, which is far more than the upper limit of the SATA2 interface, and the gap between SATA2 and 3 will be obvious.

Unless you change to an SSD, if you are an HDD, you can use it with confidence, and you may be able to see the difference between the two interfaces, but you can't actually feel it at all.

Due to the working principle of HDD, SATA3 is not very effective. It's not popular yet, and there are very few corresponding peripherals.

If you use a normal HDD, there is no difference in speed.

If you use an SSD, the difference is huge. The interface speed will be at least 50% faster.

The four satas on the motherboard are the same, no matter how many they are, you can plug them in.
