Optimization method of nine solid-state drives in Win7 system

SSD (Solid State Drive) is made up of solid-state electronic video surveillance, network monitoring Memory unit (flash chip memory chip array), which is composed of control Tan Yuan and DRAM chip. Solid-State hard disk in the interface of the specification and definition, function and use of the same as the ordinary hard drive, in the product shape and size is also completely consistent with the common hard drive. is widely used in military, automotive, industrial control, network terminals, power, medical, aviation, navigation equipment and other high-tech fields. With the price of solid-state drives falling, at present, solid-state hard disk has been widely used, some new notebooks and assembly computers have also begun to use solid-state hard disk platform, the super is not to mention that the use of solid-state hard disk has become standard, although solid-state hard disk speed, but do not understand optimization, still can not play its high-speed advantage, The following article will share with you under the current mainstream Windows7 system how to optimize the solid-state drive.

What you need to know is that for Windows 7 The optimized operation of Xitongtiandi.com SSD is mainly to turn off some unnecessary functions that will take up extra disk space and some useful to the mechanical hard disk. Harmful to the SSD, the following operation is a recommended operation with extensive compatibility, for some brands of solid-state drives and some other specific operations are not included in , please use the brand's students to find their own, such as the shutdown of Windows write cache buffer refresh for the OCZ product performance will be improved, and for Intel products may reduce performance, the following section details.

One, AHCI hard drive mode can improve hard drive performance, determine your SSD is running in AHCI mode, open "HKEY_LOCAL_MACHINESYSTEMCURRENTCONTROLSETSERVICESMSAHCI". Right-click to modify Disk mode to "0", restart can be, the following figure:

Modify the registry to open AHCI mode

Second, turn on the TRIM function to reduce disk wipe operation, extend the flash life of solid state hard disk, Windows 7 by default, the trim instruction is open, if you want to query the current status of the trim instructions, we can under the Administrator rights, access to the command prompt interface, input "fsutil Behavior Query Disabledeletenotify, and then you get feedback about the status of queries. In this case, the hint is "disabledeletenotify = 0", i.e. the trim instruction is enabled; the hint is "disabledeletenotify = 1" That is, the trim instruction is not enabled and the trim is not turned on, please update the drive and system patch in time.

Turn on Trim function

Third, turn off System Restore function, this function will affect the normal operation of SSD or trim, and then affect the ability of the SSD's reading and writing.

Turn off System Restore functionality

Turn off the disk index, the solid state drive response time is very low do not need this function, as far as possible to reduce unnecessary read and write operations beneficial solid-state drives.

Turn off disk indexing

Shut down the disk consolidation plan, which will increase disk read and write operations, the solid-state drive will not produce disk fragmentation, this feature will only increase the number of reads and writes.

Turn off the disk consolidation plan

Six, turn off disk paging, do not recommend memory less than 4G students turn off this support, but turning off disk paging saves 3-5g disk space.

Turn off disk paging

Seven, shut down the system sleep, for solid-state hard disk read speed is very fast, not necessary, can save 3GB of disk space.

The method is to enter the Start Command dialog box, and then enter the following command in the CMD command box, and then press ENTER to confirm it.

Turn off system hibernation

Eight, turn off prefetch (prefetch) and SuperFetch (super prefetch) in terms of 0.1ms-level delay does not require this technology. So the performance will improve after the shutdown. Find Hkey_local_machinesystemcurrentcontrolsetcontrolsessionmanagermemory Managementprefetchparameters Right-click Enableprefetcher and Enablesuperfetch to modify this data from (1 or 3) to 0, and then reboot.

Nine, the Quick Start system This function is shuts off the system to enter the picture, probably can save the 2-3s for you the start-up time, other option does not move, may have the negative influence. Press the keyboard win+r input msconfig, check whether no GUI guide is hooked up, if not please tick, OK.

Windows 7 has added some new random reads, Random writes, and erasure evaluations. A good solid state hard drive score will be above 6.5, the highest score of 7.9, the measurement period of 1.9 points, 2.9 points and other abnormal evaluation will not appear again. Of course, if the SSD itself is normal, the score in Windows 7 will be similar to Windows Vista and will not go up.
