All the data here is written to the controller cache so as to be available for subsequent read requests. The “Always Write-back” option enables the write cache on a permanent basis; it is also used if the battery of the BBU is empty or if no BBU is installed, whereas the “Write-back” option automatically switches to “Write-through” as long as the controller cache is not battery-buffered.

The “Write-through” option ensures that each write request from the controller is only reported back as completed when it has been acknowledged by the hard disk.
With the eas and “Always Write-back” options the requests are cached in the controller cache and they are immediately acknowledged to the application as completed and only transferred to the hard disk later. Stux and Kristian like this.

I have where applicable written which devices are cross flashable to other devices of the same chipset. Hope this is of use.
Possibly should have separate sections for 3ware and Areca, as they are LSI based and 3ware owned but they are not inter-operable. PatrickApr 21, Pieter and Patrick good job on this and the main page posts.

Solsman Dec 12, Great features and good sound, but fills a narrow niche Great features and good sound, but fills a narrow niche by Ty Pendlebury.
Disk cache mode The possible values here are “enabled” and “disabled”.
People are buying 4G LTE laptops — and then not activating LTE Lenovo has found people buy its Qualcomm-powered always-connected PCs more for their long battery life than the fact they’re always connected.
Feb 20, Messages: The “Direct” option defines that the data to be read is read from the hard disk directly and is also not stored in the controller cache. Dec 29, Messages: PatrickApr 24, But like you said not much point as you could just go to their respective website and do the same thing I’m fairly happy with the above now.
If you have a controller aas have successfully cross flashed or done something worthy, reply back here and the list will be updated. Just need some experiences of who has done what with which and why.

Gaming by Lori Grunin Dec 13, JeggsApr 27, Discussion threads can be closed at any time at our discretion. David Katzmaier updates his advice for cord-cutters, the Marriott cyberattack may be the work of Chinese spies, and Intel chips score a breakthrough.
In the case jegaraid the “Adaptive” setting the controller itself attempts to determine whether a read-ahead makes sense or not.
Do you already have an account? Maybe that becomes 88708elp page but probably not too useful.
In most cases, the enabling of the hard disk cache entails an increase in throughput for write access. Samsung and Qualcomm phone prototypes tease our 5G future But you still have sss wait for the real thing. A maximum of three options “No read ahead”, “Read ahead” and “Adaptive” are available.
Lenovo has found people buy its Qualcomm-powered always-connected PCs more for their long battery life than the fact they’re always connected. Any power failures can be bridged by means of an optional BBU, thus guaranteeing the integrity of the data in the controller cache.

StuxTheBloke and Kai Amundsen like this. Don’t cut the cord on cable like a rookie The 3: You must log in or sign up to reply here. No caching during read takes place in the case of “No read ahead”.
