When I installed an OCZ Agility-EX SLC SSD the write caching option was enabled. If I try to disable it I get this message:
--------------------------- AGILITY-EX ATA Device Properties --------------------------- Windows could not change the write-caching setting for the device. Your device might not support this feature or changing the setting. --------------------------- This might indicate that write caching is needed by SSD's. Perhaps write caching means something different for SSD's. |

Thanks for the tutorial. Increased my speed to USB HDD significantly!
[Edit] Well, it did initially. Transfer speed starts ~3x faster, then tails off to the same speed ![]() |

Hi Brink, thanx for the tutorial. I just have some questions.
The data should lose or corrupt either the write-caching is on or off?
Thank you in advance. |

Hello Rjck,
Anytime you lose power suddenly you can lose and risk corrupting only the data that happened to be in the process of being written to the hard drive. Usually restarting the computer sorts it automatically. If not, then running chkdsk can. Usually the only time you would lose anything that happened to be in the write cache is if you unplugged a external drive with write caching enabled improperly without using "Safely Remove Hardware" first. It's usually best to have write caching enabled for better performance. If you have a second physical hard drive that's just as fast, and not just another partition on the same hard drive, then you could gain performance by having the virtual memory page file on the second hard drive instead. Hope this helps, Shawn |

Hey Brink. You should add that you need to be logged in as admin in order to do these changes. The policies tab wont be there on a standard user. Thanks!
OR You have to click the change settings and give it Admin rights. Also, i have a question: Below is my Policies tab. What am i missing? |

Hello Coolness,
Note added. You're not missing anything in your screenshot. What you see and have available is dependent on the chipset driver and the hard drive. |

SSD "Enable Write Caching" turning back on after being turned off Windows 7 Ultimate x64 SP1. I've noticed this strange behaviour where, after I have un-ticked "Enable write caching" for the main (only) drive in my laptop (Intel 240GB SSD) the setting keeps getting turned on again every time Windows wakes up from sleep. I turn if off again, and then it's on again... |

Write-caching I have all my external drives set to "quick removal" option, so I don't have to use the "safe-removal" option. On my internal drives, I have it set to "Enable write caching." It says that a power outage could cause data loss. Since I always use the "sleep" option, is this option... |

Write caching or ??? With explorer. Copy a large, say 700mb file from folder a to b on a regular HDD, should take 10-15 secs right. If you watch resmon, disk activity, you will see write activity to the destination folder for almost a full minute afterwards. Anyone know what's going on here? I don't have restore... |

Write caching Ok, so my hard drive in ACHI mode does not allow me to enable write caching but in compatibility mode it does. Should I enable write caching? Also this whole thing about memory loss is bugging me on what they are talking about. I have a laptop with a battery and mostly has power. But what if... |
