What are the optimization techniques for solid-state drives?

Solid-State hard disk is called fixed disk, is a solid-state electronic memory chip array made of hard disk, its chip operating temperature range is very wide, business regulation products (0~70℃) of the product ( -40~85℃). Although the cost is high, but also is gradually popularized to the DIY market. The new generation of solid-state drives generally adopt SATA-2 interface, SATA-3 interface, mSATA interface and Cfast interface.

Let's take a look at how to make disk use more efficient.

As we all know, solid-state hard drive optimization (hereinafter referred to as SSD) can make the use of disk more efficient. Here we will teach you how to optimize your SSD in different ways. Data that may be stored during optimization is lost, so it is recommended that you back up the original data first.

SSD optimization is a very targeted setup process, this tutorial just tells you how to do, to achieve the optimal, you need to configure according to your specific needs.

Required reading: The various optimizations you perform on your computer may cause your machine to fail, so it is recommended that you back up important information before you have targeted optimizations. It is best to optimize after reloading the system to avoid unnecessary trouble.

SSD Optimization Setup Preparation

First, make sure your computer is running in AHCI mode

The first step in optimizing SSDs is to ensure that your disk read-write mode is AHCI, in general, if your computer is a windows7 system, just go to the BIOS setup before installing the system to disk read and write mode is "AHCI" can be, if you have installed Windows7, And not sure if the disk is working in AHCI mode, look at the following tutorial:

1, click Win+r, enter the Run dialog box.

2, input regedit into the registration form.


4, right button to modify the disk mode of "0", restart can be.

Second, update your chipset driver

Keeping up with the latest chipset drivers can improve system compatibility and improve disk literacy, especially now that the SSD is updated faster, it is very necessary to update the disk chipset at any time.

Trim is a very important feature that can improve the ability of the SSD to read and write and reduce latency. This is an important technology supported by Win7 and needs to be supported through upgrades.

Through the above two drives can be turned on the trim mode, many detection software can be seen, when the data deleted, the disk in the background will be trim operation.

Third, turn off System Restore function

This is a very important step, a lot of recent feedback that System Restore will affect the normal operation of SSD or trim, and thus affect the ability of SSD reading and writing.

1. Right-click My Computer Select Properties

2. Select System Protection

3. Set Item

4. Turn off System Restore

Iv. Verify that the trim is turned on

It is difficult to make sure that the trim is turned on, because we have to monitor the state of the computer very closely to judge, and often disk trim is instantaneous, so it is difficult to detect. We can see if the trim is turned on successfully in the following ways:

1. Open cmd

2. Right-click cmd to run in admin mode

3, input "fsutil behavior query Disabledeletenotify"

4. If the return value is 0, your trim is turned on

5, if the return value is 1, then your trim is on the off state

Closing the disk index

The purpose of disk indexing is to accelerate access to the appropriate folders and directories, but the SSD product itself response time is very low, only 0.1ms level, compared to the traditional hard drive more than a hundredfold, so there is no need for indexing, too much index will only reduce the life of SSD.

1, click on My Computer

2. Right-click SSD Select Properties

3, cancel the index check, click OK. Sometimes you may need to operate with administrator privileges and perform administrator privileges.

Vi. closing the disk consolidation plan

Win7 By default, disk defragmentation is turned off, but in some cases it may be turned on automatically. Because there is no fragmentation problem on SSDs, it is not necessary to open it, and frequent operations can only reduce its lifetime.

1, click the disk right key properties.

2. Select Tools tab.

3, select the disk finishing plan, click the Close Reorganization Plan button.

4, click OK.

Vii. Turn off disk paging

This is a widely debated optimization option, and many people wonder if this will improve performance. But no matter how close this option can bring you additional 3.5GB-4GB to tell storage space. We do not recommend that users with less than 4GB of RAM turn off this option.

1, right click on My Computer

2. Select Attributes

3. Select System Advanced Settings

4, optional Ability tab of the Advanced Options tab

5. Select Virtual Memory changes

6. Turn off automatic management of memory paging

7, close all memory paging, and OK, exit.

Eight, turn off system hibernation

Hibernation is a useful feature for traditional hard disks, which can quickly load the last-used program, but in the SSD era this functionality becomes useless. Because the SSD system start-up time is basically within 20s, this and the sleep mode of the start difference is not much, so instead of wasting that 2.5GB about the capacity to do dormant temporarily, or to take out.

1, shortcut key win+r call operation;

2, enter the command line "powercfg-h off"

Nine, turn off Windows write cache buffer Flush (or leave the default)

Note: Turning off the Windows write cache buffer can have two distinct consequences, one is the system read and write performance and the other is performance improvement, why this situation, because the same SSD device has a different cache, OCZ SandForce Master product is not even cached. Therefore, for OCZ products, performance will be improved, and for Intel products, we recommend that you do not check, otherwise performance will fall.

1. Right-click My Computer Select Properties

2. Equipment Management

3. Select disk Drive

4. Right-click SSD and select Properties to write cache refresh option

5, Windows on the shutdown device will appear

SSD optimization settings (3)

Ten, close prefetch (prefetch) and SuperFetch (Super prefetch)

These two technologies are XP and the Vista-era acceleration technology, for SSD, 0.1ms-level delay does not need this technology at all. So the performance will improve after the shutdown.

1, enter the registry, find Hkey_local_machinesystemcurrentcontrolsetcontrolsessionmanagermemory Managementprefetchparameters

2. Right-click Enableprefetcher and Enablesuperfetch

3. Modify the data from (1 or 3) to 0; restart

Xi. close Windows Search and SuperFetch super pre-read

1, click Win+r to enter the running menu

2, input services.msc carriage return

3, find the Windows Search and SuperFetch options, right-click Properties

5. Stop it

12. Quick Start System

This function is to shut down the system into the screen, presumably to save you 2-3s start time, other options do not move, may have a negative impact.

1, according to the keyboard win+r input msconfig

2. Check if no GUI guide is hooked up

3, if not please tick, OK.

These 12 SSD optimization techniques do not necessarily apply to everyone, and we should be treated with constant attempts to accumulate experience. As explained at the beginning of the tutorial, data that may be stored during optimization is lost, so it is recommended that you back up the original data first.
