By the way, the parallel port of the box under the 120G160G hard about how much money ?
Experts answer: to see your own requirements. First. You buy a hard drive is what to do with. (Such as karaoke machines. Business Machines. Game ....) according to your actual requirements. Such as game consoles. Usually buy a 80 - 120'll be enough. To such a big Baihua Qian. Maybe one day after 3 years it has hung up Cry dead. The following patient and open bar ** # second.'s Optional hard drive (hard disk completely Shopping guide for - the mainstream meaning of hard numbers). Now we see in the market, most of Seagate hard drive (Seagate), Maxtor ( Maxtor), Western Digital (WesternDigital) , Hitachi (HITACHI) and Samsung (Samsung) and other products from several vendors. New hard drive recently been listed on the manufacturers in the hard numbers on the definition of certain changes have taken place. Many consumers are now the number of various brand hard drive has been difficult to identify. Because each number is the hard disk Represents a specific meaning, so for us consumers, the hard numbers like the hard drive's "identity." Through these complex numbers, which we can interpret the hard drive capacity, speed, interface type, cache and other performance indicators, and information on our hard drive purchase their favorite products Very helpful. Optional hard disk (hard disk parameters and common analytical errors) in we usually buy hard disk, often hard to understand some of the parameters, and many magazine articles have also been a lot of explanation. However, in many cases, this description is not detailed or even a bit misleading Elements. Today, we chat about this topic, hoping to buy the hard drive to provide proper assistance. Optional hard work, the disk in the axial motor driven, high-speed rotation, the head arm in the voice coil motor control, carried out in the disk radial movement of the top hard drive for addressing common technical indicators The following: 1 rpm (RPM, RevolutionsPerMinute): This indicator represents the hard disk spindle motor (disk drive) speed, such as on behalf of the hard drive 5400RPM spindle speed of 5400 rpm. 2, the average Seeker Time (AverageSeekTime): If there are no special instructions generally refers to the tracking time of reading, in units of ms (milliseconds). This indicator is the meaning of hard disk read * write command received after the specified track to move to the head (should be cylindrical, but it is the specific head track) The average time required for the top. In addition to the average seek time, there are Road between the seek time (TracktoTrack or CylinderSwitchTime) and full seek time (FullTrack or FullStroke), the former refers to the head from when Go to the adjacent track before the track over the top of the time required, the latter refers to the head from the outside (or the most inner) loop inside track at the top to move the most (or most things) the time required to circle above the track, basically more than more than double the average seek time. For practical work, we generally only care about the average seek time. 3, the average The incubation period (AverageLatency): This indicator is when the head moves to the specified track after the long wait the specified time * write sector will move to the head below (disc is spinning), the disc turn faster, shorter incubation period. The average incubation period is a half circle disk rotation time used . Obviously, the same speed, the average incubation period of the hard disk is fixed. 7200RPM when about 4.167ms, 5400RPM when about 5.556ms. 4, the average access time (AverageAccessTime): also known as the average access time, vendors generally Published specifications will not be provided, which generally results in a test, its meaning is read * write command issued from the first data to use when reading * Write the average time, including the average seek time, average House operation with the relevant latency time (such as instruction processing), since the House action for a very short (Usually around 0.2ms), can be neglected, the average access time can be approximately equal to the average seek time + average latency, which is also called the average seek time. If a 5400RPM hard drive, the average seek time is 9ms, then in theory it's the average access time is 14.5
