The transfer speed of the hard disk is related to the front side bus

    Of course, it doesn't matter, the front-side bus limits the size and speed of the hard disk capacity.

    Hard disks are the biggest bottleneck of computers. The 133 you mentioned is the external transfer speed, but the internal transfer speed of the hard disk and the seek time are the bottlenecks. In terms of the PCI transmission speed of ordinary computers, it far exceeds the internal transmission speed of the hard disk, so PCI will not cause a bottleneck in the transmission of the hard disk.

    Nowadays, the read and write speed of ordinary hard disks is basically about 50-60MB s, if you only use a single disk, you don't need to consider the bottleneck of bus speed. But when you need to do arrays, you have to think about it. The actual reference is as follows:

    1. Dual hard disks can work normally with RIAD0 and ordinary 33 PCI devices, with a speed of about 90-100MB s.

    The RIAD0 requires 66 full-length PCI devices and slots, and the speed is around 170-190MB s.

    The disk needs 133 full-length PCI devices and slots to make riad0, and the speed is about 280-320MB s.

    The above is the performance of the top speed state of the IO port in practical applications, if the RIAD speed is set to be lower than the above, the requirements for the interface are also valid.

    Yes, but the speed in your hard drive is only 33ms at most!

    This is a normal rate.

    As for the speed of 100-200 m/s, it means that it can be "reached", but it may not be achieved. Because it also depends on the read speed of your hard drive, the transfer speed of the front-side bus, and so on. Usually, our ordinary computer is transferred to a mobile hard disk, which is generally 40-60M.

    Those are all theoretical data, right, my USB flash drive, and the laptop is also an interface, and the copy data has never been seen more than 100m, at most about 90m for a few seconds, and then it goes down to about 30m.

    The main bottleneck is your hard drive, not the cause.

    It's a pity that this one doesn't plagiarize the formula. The only bai that can be converted is the SATA 1 interface specification for the transfer speed du , which is equivalent to 150MB s. But this is only a theoretical value of the DAO, and the peak may be reached during the sudden transmission.

    But the sequential transfer is certainly not that high, considering that it is still a 5400rpm hard drive, and the sequential transfer can reach 50mb s is very good.

    When copying files inside the hard disk, you also need to consider the distribution of file fragments, system resource usage, and other issues. In particular, a hard disk cannot read and write at the same time, in other words, the same hard drive cannot be written when read and cannot be read when written, so the continuous transfer speed when copying a large file is much slower than simply reading a file.

    It's a bit of a problem upstairs!

    How can bus frequencies be irrelevant to memory?

    It should be closely related!

    The landlord's understanding is based on the 1333 bus, which is a bit one-sided, it should be the CPU motherboard, the memory, the three are subject to the minimum bandwidth.

    In terms of memory, Intel is dual-channel, so the frequency should be multiplied by 2, that is to say, if you want a bus frequency of 1333, two 667 memories are enough.

    Graphics card bandwidth is another form, and now the mainstream is PCI-E 16The basic support of the high-end PCI-E bandwidth is larger).

    hard disk, it is recommended to build a raidThis results in a significant increase in speed and data security.

    All configurations can be less than or equal to the board's bus, as the board has room for upgrades. The memory bus should exceed the CPU bus, for example, the U E8200 bus is 1333, then the memory 800 will need 2, that is, 1600, but it actually runs on 1333.

    The card can be used with 4850 or 4870.

    Generally, the CPU is the core, and the configuration (personal opinion).

    Let's say:"The CPU bus frequency is (MHz) 1333MHz

    Then the motherboard bus frequency should also reach 1333MHz or higher, memory.

    The graphics card has nothing to do with it, of course, the configuration must be at a certain level, so that the performance can be played. And the power supply is also important.

    Sorry, mistaken.

How to say, for example, if you copy things at home, just copy from your own computer, and the game of the Internet café is on the server, when you take the test, there is an extra link from the server to the client you use and then to your hard disk, so it is slow, if you catch up, others are also dragging things from the server, or **data, it will also affect the speed of your copying things. But there's also your hard drive port that's or of course hurry. Maybe yours is an internet café, and it's also very slow. >>>More
