How to see the hard disk read/write speed

What parameters should I look for in a fast hard disk?

One, look at the hard disk speed

The higher the speed, the faster the reading and writing speed, must be more than 7200 rpm to fast.

Second, look at the hard disk memory

The size of the memory will affect the hard disk read and write speed. 32 is low, 64M or more cache is fast.

Three, look at the interface of the hard disk

SATA3 is faster than SATA2, but this is actually not a big impact, basically can be ignored

Four, look at the seek time and continuous transfer speed

seeking time of 14ms or less, the loading of the system is relatively fast, 12, then it is better. Continuous transmission, should not be less than 180M/sec. This is not usually labeled, you have to read reviews to know.

In fact, if you want a fast hard disk, it’s best to get an SSD. random read/write (that’s how fast the hard disk seeks) is at least 100 times faster than a mechanical disk!

How to see the hard disk read speed

Do you mean real-time monitoring of hard disk read speed or read speed test?

Real-time monitoring:

If you are using Win7, you can use the Resource Monitor to see what’s going on: Right-click on the taskbar, Task Manager Performance (tab), Resource Monitor (button), Disk (tab),

The Disk Live Processes column shows the number of processes on the disk. The “Processes active on disk” column shows the hard disk read/write speeds for all current processes, and the line graph on the right shows the read/write speeds for each hard disk.

As for XP, I don’t know of any program that monitors it in real time.

If it’s a speed test, you can use software such as HDTrue to test it, or you can use Fastcopy to copy the file to test it based on the speed displayed by the software

How to check the read speed of a disk

hdparm-t/dev/sdx(x stands for a,b,c, the first hard disk is a, the second one is b. and so on.)

Very simple and good command, please refer to the book “Linux should be learned this way”

How to check the maximum read/write speed of your own hard disk

Method 1: Download this software hard disk speed measurement tool HD_Speed on the Internet;

Method 2: If it is a win7 system, you can check it through the Resource Monitor to view. Right click on the blank space of the taskbar, Task Manager, Performance (tab), Resource Monitor (button), Disk (tab).

How do I check the read speed of my hard disk?

hdparm-t/dev/sdx(x stands for a,b,c, the first hard disk is a, the second is b, and so on).

Very simple and easy to use commands, please refer to the book “Linux should be learned this way”

What software can see the read and write speed of the hard disk

LuGuardian emphasizes the ease of use, the interface is simple and easy to understand, but the measurement of the data is not specific and inaccurate, change hdtune to measure.

Run a speed test (benchmark) to see if the curve is smooth. Mechanical drives generally have a smooth continuous decline, SSDs are a straight line. See how many big ups and downs there are, and if the lowest speed is particularly low. Too much of a drop in speed means that the performance of the disk has declined significantly, and if the minimum speed is particularly low, the disk won’t last long.

What do read and write speeds mean on a hard disk

To put it this way, read speed is how fast you can read a book, and write speed is how fast you can write a book.

As for the write speed, it is generally this way, and it is not low, should the owner’s hard disk is only 64G. SSD is generally the bigger, the faster its write speed.

As for the running speed of the system, it mainly depends on the instantaneous readability of the SSD. As long as it’s a solid state drive, the system’s response time will be fast, so don’t worry about that.

I hope this helps.

What is the general hard disk read speed and write speed

Transfer rate of the hard disk: as the most important data storage device and data exchange medium in the computer, the hard disk transfer rate of the fast and slow directly affects the system’s operating speed. Different types of hard disk, its transfer rate is often very different. Now there are three main types of mainstream hard disk: according to different interfaces can be divided into parallel port ATA hard disk (i.e. IDE hard disk), SCSI hard disk and SerialATA hard disk.

IDE interface hard disk in the current computer is most widely used, the mainstream specifications include ATA/66, ATA/100, ATA/133, this nomenclature also shows that they are in the theory of the external maximum transfer rate of 66MB/s, 100MB/s and 133MB/s. Here we need to explain: 100MB/s, 133MB/s, 100MB/s, 133MB/s, 100MB/s, 133MB/s, 133MB/s, 100MB/s, 133MB/s. s and 133MB/s are peak speeds and do not indicate that the drive can sustain this speed, which means that this is the theoretical maximum peak speed.

The true transfer speed of a hard drive is affected by the internal transfer rate of the hard drive, which is generally stabilized at between 30MB/s and 45MB/s. As the CPU, memory, and other hardware are used, the hard drive can be used for a variety of purposes. In this way, as the CPU, memory and other hardware operating speed continues to improve, the low rate of the ATA hard disk gradually becomes a bottleneck affecting the operating speed of the entire machine. As a result, a new hard drive interface, SerialATA, has emerged.

SerialATA hard disk is often referred to as serial hard disk, it uses the point-to-point way to realize the data group transmission and thus bring higher transmission efficiency. serialATA1.0 version of the hard disk’s starting transmission rate of 150MB/s, and SerialATA3.0 version will realize the hard disk’s peak data rate of 600MB/s, which will finally realize the hard disk’s peak data rate of 600MB/s, and thus finally realize the hard disk’s peak data rate of 600MB/s. 600MB/s, thus finally solving the system bottleneck problem of hard disk.

The SCSI interface is not specifically designed for hard disks, but is actually a bus-type interface that operates independently of the system bus. SCSI interface hard disks are widely used in servers and professional workstations for their high stability and low CPU occupancy, with transfer rates of up to 320MB/s. Of course, for the hard disk’s overall performance, in addition to the hard disk’s transfer rate, the hard disk’s performance will also be improved. In addition to the hard drive’s transfer rate, the speed, cache, and average seek time of the hard drive are also important factors.

Trivia: 1. Internal data transfer rate

The internal data transfer rate is the rate at which data is transferred from the magnetic heads to the drive’s cache, which can be considered critical to the overall performance of the drive, and is generally dependent on the speed of the drive’s platters and the density of the platter data lines. In this indicator often use MB/s or Mbps as the unit, which is the meaning of megabits per second, if you need to convert to MB/s (megabytes per second), it is necessary to divide the Mbps data by 8. For example, there are hard disk to give the maximum internal data transfer rate of 240Mbps, but if the calculation by MB/s will be only 30MB/s. This can be seen that the hard disk as a bottleneck of the computer at present. The root of the problem lies in the internal data transfer rate of the hard disk.

2. The external data transfer rate of the hard disk

The rate at which data is read from the hard disk’s buffer. It is directly linked to the type of interface of the hard disk, so in the advertisement or hard disk characteristics table is often replaced by the data interface rate, the unit is MB/s such as what we usually say ATA100/133 hard disk.

Optical drive transfer rate: usually the optical drive transfer rate depends on the multiplier speed of the optical drive, such as 16X DVD, 52X CD-ROM, in general, the higher the multiplier speed of the optical drive, the faster the data transfer. What is the concept of “speed”? It turns out that a long time ago, CD-ROM transmission rate is very low, only 150KB bytes per second, that is, the initial optical drive rate of 150KB / s, which is 1X (single speed) CD-ROM optical drive. Later, with the CD-ROM optical drive technology is changing day by day, its rate is getting faster and faster, in order to distinguish between different rates of optical drives, so the initial 150KB / s as a benchmark for measuring the corresponding times the speed value. Such as 50X CD-ROM means that its transmission speed is 1X CD-ROM drive 50 times that its rate of 50 × 150KB / s = 7500KB / s. And now the popular DVD-ROM rate algorithm is basically the same, but the DVD-ROM single rate than the CD-R……

How fast is the hard drive read/write speed

Ss guts are much faster than mechanical disks, there’s no comparison of just saying the numbers don’t make sense you’ve personally used them and you’ll know that the general mechanical disks on laptops are 5,400 rpm.

raid0, the speed is the sum of several hard disks.

The speed is the sum of several hard disks minus 1. For example, 3 hard disks, each with 100M/s, is 200M/s.

But note that the sata interface has a bandwidth limit.

If your hard drives are all plugged into the sata interface on the motherboard, that’s not a big problem. If they are picked up through a disk array, then there are limits to going through interfaces like sata and u***.

The limit of sata2 is about 260M/s. The limit of sata3 is about 550M/s.
