You will need
- connection to the Internet.
- - special software.
Look in the manual to figure out the model that is installed on the computer device for data storage.
Go to the Internet. Just search for "HDD forum". Explore the information on the forums, where users discuss the specifications of hard drives which they use software to determine and adjust the spindle speed. Here are some addresses of major websites where you can get help and good advice: ClubControl (http://www.clubcontrol.ru/forum/), HDD forum (http://hdd.kulichki.com/forum/), Monitor (http://monitor.net.ru/forum/) etc. On the Internet you can find a large number of programs, both paid and free. However, not all of them work equally well with various models of hard drives.
Download and install the necessary software. Now turn the computer off and let it rest 10-15 min. To determine the actual rotation speed of the disk must be measured in the system, which has not yet managed to get a heavy load and is in perfect condition.
Run the program. Examine the list of physical disks that are presented in list or chart. Select the drive whose information you need to know now.
Test speed called Benchmark. Usually the test fails to obtain information which give a completely objective picture of the status of the disk as a whole. Click Start and wait for completion of test.
Analyze data collected by the program. Please note a few critical points. First, look at the value of the Transfer Rate Minimum. This figure determines the minimum data transfer speed, while the Maximum Transfer Rate indicates the maximum. Then move on to medium speed, called Transfer Rate Average. Write down the numbers or save them in any other way.
Note Access Time - an indicator describing the average access time to files, which is measured in milliseconds. Along with the Burst Rate (peak speed HDD) Access Time is a very important characteristic to consider. Fix also data about the CPU load during rotation of the hard disk.
Compare all the collected program data with the ones provided by the HDD manufacturer in the instruction manual of the PC. Pay attention to the fact that the numbers of indicators can differ significantly, however, this is not always indicative of damage to the HDD. A great influence on the results of the tests provide the conditions for its operation.
Advice 2 : How to know the speed of the stick
The main characteristics of the stick, or rather a USB stick, are its capacity and performance. Under the performance of the stick you know the speed of read and write information in megabytes per second. To know the speed of the flash drive by the experimental read and write large amounts of information.
You will need
- USB flash drive, computer
The manufacturer specifies the speed of reading and writing stick in its specifications on its official website. Write speed may be three times less than speed of reading. Performance, specified in megabits per second is 8 times less than the speed specified in megabytes per second. In the Datasheet of the flash drives is the interface through which you can determine the performance of the stick. The most common USB 2.0 port. Its maximum speed transfer of 480 Mbps or 60 MB/s. In reality the performance is rarely more than 30 MB/s.
Specified in the technical specifications of the manufacturer , the speed of read and write data does not match the actual, which depends on the computer and the operating system. To determine the actual speed it is necessary to test the flash drive on your PC installed on it OS. On the stick first recorded one large file volume of 600?700 megabytes, for example, a downloadable film, measured and spent time on it. So we define the speed record. For more speed I need to write about ten small files of the same total volume and measure the time of their recording. You can then calculate the average speed of the two obtained results and to continue to focus on it. To determine the speed of reading, carry out the reverse operation in the same manner: read a large file from pendrive to your hard disk, measure the time taken to read the same amount of small files, and again measure time. Calculated reading speed in both cases. The arithmetic average of these two velocities will indicate the speed of reading information from the specific USB drive on the computer when its operating system.
If the resulting speed read/write stick is insufficient to operate with large volumes of information, it is possible to acquire a keychain from NAND memory, which productivity is higher.
