Windows 7: Optimize Windows 7 for use with a Solid State Drive (SSD) (page 2)Windows 7: Optimize Windows 7 for use with a Solid State Drive (SSD) (page 2)By: Arie Slob. Windows Settings.
Yesterday I explained about both Prefetch and Superfetch. Both Windows Vista and Windows 7 contains Superfetch since it is more advanced and uses more comp.
The first item we need to check is to make sure your SSD isn't scheduled for disk defragmentation. Windows 7 will automatically disable scheduled defragmentation when it detects it is installed on an SSD drive. Disk defragmentation is unnecessary on an SSD drive and can even have a negative effect on the endurance of the drive. If you have multiple disk drives, you should see the (Select all disks) and any/all of your non SDD drives selected (Figure). These technologies were all designed to improve performance on traditional HDDs, where random read performance could easily be a major bottleneck. Looking for root causes Microsoft engineers found that some first generation SSDs had severe enough random write and flush problems that ultimately lead to disk reads being blocked for long periods of time.
Black Viper’s Top 8 tweaks for a faster (and less annoying) Windows 7 PC The following is what I do directly after a clean install of Windows 7. This does not mean.

With Superfetch and other prefetching re- enabled, performance on key scenarios was markedly improved. According to Microsoft if Super.
Hi, The answer to your first question: What exactly is SuperFetch? Does it have anything to do with drivers? SuperFetch is a service that was introduced with Vista. Prefetch is a feature, introduced in Windows XP, that stores specific data about the applications you run in order to help them start faster. Prefetch is a. This annoying system pig-out is caused by a Windows Vista mis-feature (piece of crap) called SuperFetch. While the service still exists in Win7 it's been fixed up and. Gestion de la mémoire avec SuperFetch et ReadyBoost; Prefetch et Superfetch avec un lecteur SSD; Prefetch; Vider le dossier Prefetch; Superfetch; ReadyBoost.
Fetch detects that the system drive is a fast SSD (as measured by Windows Experience Index (WEI) Disk score), then Super. Fetch turns off Ready. Boot, Ready. Boost, and the Super. Fetch service itself. According to Microsoft documentation, better SSDs can score above 6. To be included in that range, an SSD has to have outstanding random read rates and be resilient to flush and random write workloads. To double- check I checked the registry, which confirmed that both Prefetch and Superfetch were set to run.
Check that the service Superfetch is set to Disabled. The TRIM command allows the operating system to inform the solid- state drive which data blocks (e. That's another reason why you'll need to check on the latest firmware from your SSD manufacturer. For example, Intel firmware versions prior to 2.
CV1. 02. HA did not support the TRIM command. Let me offer you my insights. The TRIM command is an actual ATA protocol command, specifically DATA SET MANAGEMENT command 0x. If you want to read about it, please see the ATA- 8 ACS- 2 working draft document. Any device that speaks the ATA protocol - - such as SATA hard disks - - and supports 4. LBA addressing, can support the TRIM command.
You can submit this command to the drive via a standard ATA CDB message and it will work. You don't need AHCI to send this command.
If your system is capable of running in AHCI mode, you would definitely want to run in this mode! AHCI will add Native Command Queuing (NCQ) which will boost performance. AHCI also adds Device Initiated Power Management (DIPM) (more useful on a Laptop to increase battery life) and will give you hot- swap ability.
For more information on enabling AHCI after you have installed Windows without AHCI enabled, see further below under SATA - AHCI. Besides checking & configuring Windows 7 for proper use with an SSD drive, it'll also confirm if your SSD drive supports the TRIM command. If you don't have an Intel SSD drive you can still use the SSD Toolbox to confirm if your drive will accept the TRIM command: Click the Drive Details button on the Drive Summary page, scroll down to Word 1. Data Set Management Support. If it shows 0. 00. TRIM (Figure). Run this command from an elevated command prompt in Windows 7: fsutil behavior query disabledeletenotify. In this case the return Disable.
Delete. Notify = 0 means TRIM support is enabled in the OS (which is Windows 7 default, even on 'normal' hard disk drives). The TRIM operation is fully integrated with partition- and volume- level commands like Format and Delete, with file system commands relating to truncate and compression, and with the System Restore (Volume Snapshot) feature. AHCI exposes SATA's advanced capabilities - such as hot swapping and native command queuing (NCQ) - such that host systems can utilize them. Specifically the 'native command queuing' will give SSD drives a performance boost. When you restart and Windows loads, it will load the AHCI driver & asks you to reboot your system. First we'll have to set Windows 8 to boot into Safe Mode.
Open an elevated command prompt (type CMD on Windows 8 Start screen, right- click the Command Prompt app and click Run as administrator from the menu (Figure)) and type the following command bcdedit /set . After saving the BIOS changes, restart your system. Windows 8 will boot in Safe. Mode. Open an elevated command prompt and run the following command to remove the Safe. Mode boot option: bcdedit /deletevalue .
Restart the computer and boot normally, you should now be running in AHCI mode.
