Windows 7 SP1
Latest RAID Drivers
Latest motherboard bios (Crosshair V Formula)
RAID 0 array setup using RAIDXpert
Disk drives --> AMD 2+0 Strip/Raid0 --> Double click --> Enable write caching on the device
Logical Drive View --> Settings
In Device Manager "Enable write caching on the device" is not checked by default.
This value though can be changed via RAIDXpert.
This is what happens
If we check the "No Cache" option and apply the setting this will change the "Enable write caching on the device" setting in Device Manager to be checked.
If we check either the "Read Cache" or "Read Ahead" then the "Enable write caching on the device" in Device Manager will be unchecked.
Is this what is meant to be happening ?
Using RAIDXpert, "No Cache" performance using AS SSD with 4K writes is arnd 60 MB/s, using "Read Ahead" performance is arnd 120 MB/s.
The thing is, this disables the "Enable write caching on the device" setting in Device Manager, but wherever I have read about optimizing SSD performance it is said that this setting needs to be enabled, hence the reason I am somewhat perplexed by what I am seeing.
So hopefully someone can chime in and offer their experience/opinions on this issue.
