Windows 7: Write-Caching - Enable or Disable

How to: Set up Intel Smart Response Technology (SSD caching)
That wouldn't be the same as the write caching in the tutorial.

Yep, you would need multiple SSDs in a RAID setup for SSD caching mention in the link you posted.

This feature requires that the SATA controller be set to RAID mode via the system BIOS. Intel® Smart Response Technology is an Intel® Rapid Storage Technology (RST) caching feature that improves computer system performance. It allows a user to configure computer systems with an SSD used as cache memory between the hard disk drive and system memory.

This provides the advantage of having a hard disk drive (or a RAID volume) for maximum storage capacity while delivering an SSD-like overall system performance experience. Intel® Smart Response Technology caching is implemented as a single drive letter solution; no additional drive letter is required for the SSD device used as cache.

You can use a SSD to cache your secondary drives and RAID arrays. Just remember all data on the SSD you use will be wiped when you accelerate the other drives. And you can only have one volume accelerated at a time.

Buffer flushing?

What does buffer-flushing even do to an internal hard disk drive? It won't most likely work, unless you're using a Solid-State disk drive with battery-backed DRAM cache.

Hey HC,

A flush buffers command, which is available for SCSI and IDE/ATAPI disk devices, instructs the disk to write all cached data to the disk immediately.

Many disk devices provide enhanced performance through the use of an onboard cache, which provides read-ahead caching for data that is being read from the disk, and write-behind caching (or delayed writes or "lazy" writes) for data that is being written to disk. In some cases, it is important for data to be written to the physical disk immediately, and not retained in the disk's onboard write cache to be written later during an otherwise idle moment. This prevents loss or corruption of this data if the disk or controller (wherever the write cache is implemented) suddenly loses power.

It is recommended to have write caching enabled for internal hard drives (SSDs & HHDs). :)

I purchased a usb flash drive (Corsair Voyager 16 GB) and after enabling write-cache and clicking OK, the window or dialog box of properties freeze and there is no way regular way to close it, the only way is disconnecting the usb flash, but if i connect it again it the system don't detect it unless i restart the laptop after that i connect it and it works, but the changes to write-cache were not saved. What could cause the freeze? i have 3 more usb flash, one of the is Corsair too and none of them suffers from this freeze.

Hello LM,

It's usually recommended to have write caching disabled for USB flash drives since they are removable drives. This way you would be able to simply unplug and plug in the USB flash drive at will when it's finished copying files without having to worry about corrupting them or using Safely Remove Hardware. :)

Hello Shnxxx,

It appears that your Toshiba external USB 3.0 device doesn't support changing its write caching settings.

It is important to understand that the caching is internal to the drive and not something managed by Windows. Windows can only request that this caching be enabled or disabled and it is up to the drive whether or not to honor this request. It is not required of a drive to do so. If the drive does not support a change there is nothing you can do.

Hey John, :)

It can vary a bit per drive for exactly what you see based on what type of drive it is. What you see is normal though.

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...

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...
