The other seek time and so on basically do not feel the difference
Question 2: How to look at the performance of the hard drive is good or bad hard drive performance is related to a lot of things!
RPM is just one aspect, but there are also single-disk or multi-disk, head count, cache, etc. In general, a good hard drive is a single-disk, high speed drive! In general, a good hard disk is a single disk with a high capacity and high speed, and a large cache!
For example, a laptop's high-end disk is a 7200 RPM, single-disk 500G. 16M cache!
If you want to test your hard disk good or bad, you can use ATTO this tool test!
Question 3: How to test the performance of mechanical hard disk can be tested with HD TUNE software
Question 4: How to analyze the performance of mechanical hard disk Mechanical hard disk performance does not have to be analyzed, are half a catty, about the same, there will be no significant difference.
As long as it is the latest product, 7200 rpm, it is almost the same.
Question 5: The difference and performance of mechanical hard drives and solid state drives Hard drives are divided into solid state drives (SSD) and mechanical hard drives (HDD); SSDs use flash memory particles to store, and HDDs use magnetic disks to store.
Mechanical hard disk is the traditional ordinary hard disk, mainly consists of: platters, heads, platter spindles and control motors, head controllers, data converters, interfaces, caches and other parts. Mechanical hard disk in all the platters are mounted on a rotary axis, each platter is parallel between the platters, in each platter on the storage surface there is a magnetic head, the distance between the magnetic head and the platters is smaller than the diameter of a hairline, all of the magnetic head is associated with a magnetic head controller, by the magnetic head controller is responsible for the movement of the magnetic head. Heads can move along the radius of the disk, coupled with the disk's high-speed rotation of several thousand revolutions per minute, the heads can be positioned in the designated location of the disk for data reading and writing operations. As a precision device, hard disks are the enemy of dust and must be completely sealed.
A solid state drive (Solid State Disk or Solid State Drive), also known as an electronic hard disk or solid state electronic disk, is a hard disk that consists of a control unit and a solid state storage unit (DRAM or FLASH chip). The interface specifications and definitions, functions and usage of a solid state drive are the same as those of a mechanical hard disk, and the shape and size of the product is also the same as that of a mechanical hard disk. Because SSDs do not have the rotating media of mechanical hard disks, they are extremely shock resistant. Its chip has a wide operating temperature range (-40~85 degrees Celsius). It is currently widely used in military, automotive, industrial control, video surveillance, network monitoring, network terminals, electric power, medical, aviation, etc., navigation equipment and other fields. Currently due to the high cost, but also gradually popularized to the DIY market.
At present, most of the personal computers, whether desktop or laptop, are mechanical hard disk, such as the popular 320G, 500G, 640G, 1TB, etc. are mechanical hard disk. Recently began to fire up the superbook. It has begun to appear to use the solid state hard disk, but the capacity is still relatively small, generally 20G, 64G, 128G, the largest only 256G. At present, the main solid state hard disk cost is relatively high, coupled with the support of other hardware, but also has not yet reached the popularity of the degree, so it will take a few years to develop, I believe that in a short period of time, the solid state hard disk will be popularized in the application of personal computers.
Comparison of the advantages and disadvantages of mechanical hard drives and solid state drives
1, shock resistance: the current mechanical hard drive are disk-type, data stored in the disk sector. And solid state hard drive is the use of flash memory particles (i.e., the current memory, MP3, U disk and other storage media) made, so the SSD solid state hard drive does not have any mechanical parts inside, so that even in high-speed movement or even accompanied by flipping tilt will not affect the normal use of the case, and in the event of a collision and shock can be the possibility of data loss is reduced to a minimum. Compared to mechanical hard drives, solid hard drives have an absolute advantage.
2, data storage speed: From the PConline evaluation room review data, solid state hard disk relative to the mechanical hard disk performance increased by more than 2 times.
3, power consumption: The power consumption of solid state drives is also higher than that of mechanical hard drives.
4. Weight: SSDs are lighter in weight, 20-30 grams lighter than regular 1.8-inch hard drives.
5, noise: because the solid hard belongs to no mechanical parts and flash memory chips, so with a small amount of heat, heat dissipation, etc., and there is no mechanical motor and fan, the working noise value of 0 decibels. Mechanical hard disk is much less.
6, price: the current market 80G Intel SSD, the price is about 4000 yuan. And this price is enough to buy a few mechanical hard disk with a capacity of 1TB.
7, capacity: solid state drives are currently the largest capacity of only 256G (IBM has begun testing the capacity of 4TB high-speed SSD group), and the mechanical hard disk maximum capacity measured by TB compared to a large gap.
8, life: SLC only 100,000 times read and write life, low-cost MLC, read and write life of only 10,000 times; compared to mechanical hard disk has no advantage to speak of.
Question 6: How many points is normal for hard disk performance? 5 points. A normal hard disk is normal for 2000 points.
Solid state drives must be at least 6000 points to be considered normal. High-end models can easily pass 10,000 points.
Conclusion: Your hard drive has a normal score.
Question 7: Computer Hard Disks Solid State Disks Mechanical Hard Disks Read performance There is a certain impact, but the impact is not significant, it is recommended to still install the game, etc. in the installation to the system disk. This is at most a slower read when installing, but the impact can be almost negligible. Unless the video is 4K raw, a mechanical hard drive will generally be able to read the player's data at the same speed.
Question 8: What is the performance of hybrid hard drives? How much of a performance boost is there over a mechanical hard drive? There is basically no improvement in sequential data reads.
Small data, random data reads are much better.
If you already have a mechanical hard drive and want to replace it with a hybrid hard drive, there is no need to do so, especially if you have Win7, you can buy an 8G USB drive and plug it into the back of your computer, and start the readyboost function instead of a hybrid hard drive to improve performance.
It is recommended to get the hybrid drive if new.
Question 9: What is the difference in performance between a mechanical hard disk in a computer, and a removable hard disk? 20 points Hello, friend. Glad to answer your question!
Mechanical hard disk (HDD): that is, the traditional ordinary hard disk, mainly composed of: platters, heads, platter spindle and control motors, head controllers, data converters, interfaces, caches and other parts. At present, our computers are generally mechanical hard disk, and there is a feature is a large capacity, but the price is relatively cheap.
Performance: 1. Mechanical hard disk is less resistant to shock and fall, and subject to strong impact, the data may disappear, or even hard disk damage.
2. Data storage speed, mechanical hard disk is faster than the mobile hard disk. But it is far less than a solid state hard disk.
3. In terms of lifespan, a mechanical hard disk will last longer than a mobile hard disk.
This is an example of a mechanical hard drive.
This is the Seagate mechanical hard drive I just took a screenshot of, and it's really low enough to have 1000GB at this price point. Seagate's hard drive is still good ~
Mobile Hard Disk (MHD): as the name suggests is a hard disk as a storage medium, the exchange of high-capacity data between computers, emphasizing the portability of the storage product. The vast majority of mobile hard disk on the market is based on standard hard disk, and only a small portion of the micro hard disk (1.8-inch hard disk, etc.), but the price factor determines the mainstream mobile hard disk is still based on the standard notebook hard disk. Because of the use of hard disk as a storage medium, so the mobile hard disk in the data read and write mode and standard IDE hard disk is the same. Mobile hard disk mostly uses USB, IEEE1394 and other interfaces with faster transmission speeds, which allows higher speeds for data transfer with the system. As of 2009, the read speed of mainstream 2.5-inch brand mobile hard disk is about 15-25MB/s, and the write speed is about 8-15MB/s.
Mobile hard disk features: 1. large capacity 2. small size 3. faster speed 4. easy to use, like a super U disk 5. easy to carry
This is the example of the mobile hard disk
This is my I just took a screenshot of the price and parameters of the portable hard disk.
I hope this helps you, my friend! I'm Capricorn.
Question 10: computer hard disk which is better, specifically how to see the good and bad 10 points At present, the computer hard disk you mainly look at a few points, the mechanical hard disk generally look at the interface, the speed and the size of the cache, the cache is large read storage speed will be faster. Solid state hard disk generally look at the chip, there are mainly the following types of chips.
SLC = Single-Level Cell, i.e. 1bit/cell, fast speed, long life, expensive (about 3 times the price of MLC), about 100,000 times erase life
MLC = Multi-Level Cell, i.e. 2bit/cell, fast speed, life expectancy, price, about 3000 - 10,000 times erase life
MLC = Multi-Level Cell, i.e. 2bit/cell, speed, life expectancy, price, about 3,000 - 10,000 times erase life.
TLC = Trinary-Level Cell, i.e. 3bit/cell, also called 8LC by Flash manufacturers, slow speed, short life, cheap price, about 500 erase life, no manufacturer can do 1000 times yet.
My suggestion is to choose MLC for 64G, because the life span is longer, and the time spent is also longer
If the life span of TLC is more than 128G, it is also acceptable
