How to use an SSD to avoid slower and slower writing

1. SSD SSD installation and operation environment: mode, 4K alignment, XP system or above. To ensure high speed, of course, it is best to have an interface on the motherboard.

XP system and RAID mode all have an impact on the use of TRIM (of course, it is also possible to use TRIM, but with some limitations). 4k alignment, of course, is the bare minimum and a must.

2. When using SSD solid state drives, it is best not to write a large number of times for a long time. It's best to play the movie and go down to the HHD hard drive. A large number of writes over a long period of time can put a heavy load on the GC, resulting in slow, concentrated writes, and hurting SSDs.

3. The SSD retains enough space. Either your own SSD SSD has a large capacity, or you should hang an HDD.

4. Small partitions, less partitions. The "small partition" here, SSD SSD manufacturers have already made, and it is hungry OP to reserve space. For example, a 128G SSD has a usable capacity of 120G.

On the one hand, the capacity of mainstream SSDs is not very large, and more partitions mean more space wasted (there is always some space in each partition that cannot be used), on the other hand, too many partitions can easily lead to partition misalignment, and the SSD performance in the disk area at the partition boundary may be affected. And, for example, it's much faster to search for a file on a D drive than for that file on an entire hard drive.

5. Clean up your browser cache regularly. Browser caching can bring a lot of junk.

6. Be cautious with anti-virus software. First of all, don't install several antiviruses, just use one. Because one mountain cannot tolerate two tigers, installing two antivirus software is very likely to kill your computer with a blue screen, black screen, restart, etc., even if there is no one for the time being, two antivirus software will make your hard drive a lot of pressure.

The simpler the antivirus software, the better, otherwise it will mess with your hard drive and sooner or later it will die.

7. Refresh the firmware. There are some bugs in the firmware of the SSD, and the new firmware, which fixes some problems, will make the SSD performance better.

8. If the SSD is too slow for you to bear, then EC (Secure Erase), or a rough and direct format to start over. Of course, these are all harmful, and SE is less harmful to SSD SSDs. Formatting is equivalent to losing 1P E of the SSD.

Please be cautious about TLC NAND's SSDs. MLC's SSD SSD can then be let go, don't care. The ** of SSDs is still high for the time being.

High-capacity SSDs** are expensive. Choosing a small-capacity cheap SSD installation system, plus an HDD as a storage "warehouse", is the choice of many people. A small-capacity SSD with MLC flash memory is a good choice.

Reserve a certain amount of space and set up 4kb alignment.

Dynamic and funny** A joke every day, happy for a lifetime Solid state drive (SSD) If you just bought it, there is no data stored in it. It's the fastest at this point, but if you've been using it for a while, the SSD will get slower and slower as the data increases. But if you are using a regular hard disk, what is the reason for this?

We all know that one of the differences between SSDs and HDDs is that since the data storage of HDDs (HDDs) is in the form of magnetic media, when we need to store data into HDDs, the head will magnetize the magnetic media on the platter. Regardless of whether there is data in the hard disk or not, the operation is the same, and the original magnetic medium is re-magnetized.

Therefore, in terms of technical implementation, there is no situation where the mechanical hard disk is used more and more slowly. However, the data written by the SSD is very different from that of the ordinary hard disk, if the SSD is just bought and it is empty (no data is stored), then the written data is like a water cup filled with water, and you can store it directly. However, the SSD has been used for a long time and there is more and more data in it, and if you want to write data to it, you have to empty the "water cup", so it must first erase the original data before you can store the data in it.

In this way, there is one more erasing step, the more data you have, the more erases you have, and the speed will slow down. Of course, the speed of this SSD will not continue to decline, it will have a stabilization period, the sequential write speed of this stable period is only about 20% slower than the sequential write speed when the disk is empty, and the read and write speed is about 6% or so in terms of sequential or 4KB read and write, and the overall decline is not particularly large. Of course, the decline may vary from SSD to SSD, and I believe this problem will be gradually alleviated as SSD technology continues to improve.

If you want to [change the device] to greatly improve the performance of the computer, then the first choice for this device must be the hard disk, why? How do we choose the right SSD?

There are a few reasons why SSDs are slow to write:

1.SSDs do not have 4k aligned manuscript shipments.

2.SSD 3ahci IDE mode error.

3.SSD disk mode error.

4.The solid-state hard digging disk SATA2 3 interface is different.

5.SSDs use asynchronous flash memory.

About what SSDs are and the advantages over HDDs:

Solid-state drive is referred to as fixed disk, and the solid state drive is a hard disk made of a solid-state electronic memory chip array, which is composed of a control unit and a storage unit (flash chip, DRAM chip). SSDs are exactly the same as ordinary HDDs in terms of interface specifications and definitions, functions and usage methods, and are completely consistent with ordinary hard sail beam disks in terms of product shape and size. It is widely used in military, vehicle, industrial control, ** monitoring, network monitoring, network terminals, electric power, medical, aviation, navigation equipment and other fields.

The operating temperature range of its chips is very wide, commercial products (0 70) and industrial products (-40 85). Although the cost is higher, it is gradually becoming popular in the DIY market. Because SSD technology is different from traditional hard disk technology, many new memory manufacturers have emerged.

Manufacturers only need to buy NAND memory, and then cooperate with the appropriate control chip, and then they can make SSDs.

Data storage speed: In the same configuration, the read speed of the gold speed SSD can basically be around 500MB s, while the mechanical hard disk is within 150MB s. Such a difference in speed will be very noticeable to the improvement of the computer's response speed.

Shock-resistant and drop-resistant: Traditional hard disks (ATA or SATA) are disk-type, and data is stored in disk sectors. The SSD is made of flash memory particles, so there are no mechanical parts inside the SSD, so even if it is moved at high speed or even when it is flipped and tilted, it will not affect the normal use, especially when used in laptops.

Power consumption: Also because there are many fewer mechanical parts, the power consumption of SSDs is also better than that of traditional HDDs.

Weight: SSDs are lighter in terms of weight, a few tens of grams lighter than regular inch drives.

Noise: Because the solid-state drive has no mechanical parts and flash memory chips, it has the characteristics of low heat generation, fast heat dissipation, etc., and there is no mechanical motor and fan, it is silent when working, and the noise value is 0 decibels, which makes the traditional mechanical hard disk much inferior.

The reasons for this are as follows:

1. The performance of the SSD is degraded due to the energy-saving mode turned on on the motherboard

Usually, the motherboard's energy-saving function is enabled, and the CPU frequency will be reduced, which will also lead to a decrease in the performance of the SSD, because the CPU frequency will be reduced by 10% when saving energy, and it will be 10% slower when sending instructions, so the theoretical SSD performance will be reduced by 10% during the test, so if you want to give full play to the best performance of the SSD, please do not turn on the energy-saving mode on the motherboard.

2. Misconnection to the third-party SATA3 interface affects performance

Now the new motherboard supports SATA interface, and the use of SATA interface is also very important for SSD, if the motherboard we choose does not support SATA connection, then it will have a greater impact on the performance of SSD. On the other hand, the test results of the third-party SATA3 interface solution are almost completely inferior to the results of the native SATA3, especially in the startingApplications speed, which is a full 20MB difference. As a result, the score dropped significantly, and the use of a third-party SATA3 chip solution greatly slowed down the random speed, resulting in a sharp drop in performance.
