Which hard disk read/write speed is important

Write vs. read speeds on SSDs, that one is more important, don’t play word games that others have played! What’s important for writing and what’s important for reading!

Read speed is very important to the call of this machine, because the software running to load data, read faster open speed will be faster, running more smoothly. And write speed is related to our download speed (including the speed of copying files from other places). If, for example, a memory card has only a few megabytes of write speed (SSDs are the same as memory cards), it’s obvious that copying files can easily take hours, whether you’re receiving or sharing. In short, read speed matters when we want to call a file, and write speed matters when we want to drop a file on it.

SSD write speed and read speed which is important

It should be said that write and read are important, I’m here to give a simple example, the proportion of you to open a game or open an application, this time is used to read, and you copy a file from the C disk to the D disk is used to write, of course, in the game or application not only to read, but also to write. There is also writing. So both are important.

Which is more important, read speed or write speed

Read speed is more important, especially for USB flash drive which is used to store audio/video media, read speed is directly related to smoothness.

And when running certain programs loaded on a USB flash drive, faster reading = faster loading into memory, so naturally the whole thing runs faster.

U disk inventory is small, write speed relatively does not affect the use of experience, after all, write a large number of data needs is the mobile hard disk. In addition, when formatting the U disk, the appropriate enlargement of the unit space, will greatly enhance the write speed, the cost is only a small reduction in the inventory, for the requirements of the speed of the user is a very cost-effective setup.

What is the difference between the write speed and read speed of a hard disk?

1, write speed is mainly the speed of recording external data into the storage device, can be understood as the equivalent of paste speed.

2. Read speed is the speed at which data is extracted from a storage device, which can be understood as the speed equivalent to copying.

In the computer more important storage device for the memory, its storage speed is generally measured by the access time, that is, each time with the CPU and the data processing between the time spent in nanoseconds (ns) as a unit. Most current SDRAM memory chips have access times of 5, 6, 7, 8, or 10 ns.

Expanded Information

Using flash memory as the storage medium, read speeds are faster relative to mechanical hard drives. SSDs don’t use magnetic heads, and seek time is almost 0. Sustained write speeds are amazing, and most SSD vendors will claim that their SSDs have sustained read/write speeds of more than 500MB/s, and in recent years, NVMe SSDs can reach around 2,000MB/s, or even 4,000MB/s or more.

Solid state drives are faster than just sustained read/write speeds, and faster random read/write speeds are the ultimate goal of SSDs, which is most directly reflected in the majority of daily operations. In addition, they have extremely low latency, with the most common 7200 rpm mechanical hard drives having seek times of 12-14 milliseconds, while SSDs can easily reach 0.1 milliseconds or less.

Booting a system that reads the contents of your hard drive for the vast majority of its operations is a matter of reading the drive’s contents, so of course the read speed is more important.

The performance of the hard disk is good or bad to see what aspects

1, hard disk single disk capacity

The hard disk’s single disk capacity directly determines the hard disk’s continuous data transfer rate. The larger the capacity of a single disk, the better the read and write speed of its hard disk.

2. Speed

Speed is one of the most important parameters of hard disk rating. The internal transfer rate of the hard disk is one of the key factors determining the internal transfer rate of the hard disk, which directly affects the speed of the hard disk to a large extent. The faster the speed of the hard disk, the faster the hard disk searches for files and the faster the relative hard disk transfer rate. When a computer’s hard disk speed increases, the computer’s read and write speeds also increase.

3, hard disk cache

The cache capacity of the hard disk is also a parameter that determines the performance of the hard disk. Ordinary hard disk caches are physical caches. In this case, the bigger the cache, the better. Now, the mainstream 1TB ordinary hard disk has 64M cache. In this way, the performance of the hard disk is quite good

4, the average seek time seek time refers to the hard disk after receiving system commands, the magnetic head from the beginning of the track to move to the data where the average time of the track. It reflects the ability of the hard disk to read data to a certain extent, and is an important parameter that affects the data transfer rate inside the hard disk. The shorter the time, the better the product performance.

Expanded Information:

There are basically three types of hard drives on the market today, namely, mechanical hard drives (HDD traditional hard drives), solid state drives (SSDs), hybrid hard drives (HHDs), and new types of hard drives based on the superimposition of traditional mechanical hard drives and SSDs.

1, mechanical hard disk

Mechanical hard disk in high-speed operation of the magnetic head to reach a predetermined position to read and write data. Data information is written to the disk by changing the magnetic polarity of the magnetic head, which is a hair’s breadth away from the magnetic surface, and data information can be read in the opposite way.

2. Solid State Disk

Solid State Disks and hard disks have the same functions, specifications, and uses. Due to its pure chip structure, the size and weight of an SSD is much smaller than that of a hard disk.

3. Hybrid hard disk

Hybrid hard disk is a combination of mechanical hard disk and solid state disk. It is mainly used in personal computers. It has the advantage of being faster and consuming less power than a mechanical hard disk.
