It is possible that this will change in the future, but at the present moment this strategy is so pervasive that drive manufacturers presume write-back caching to be enabled when certifying their ATA products.
Though performance enhancement is helpful, the use of write-back caching in ATA RAID implementations presents at least two severe reliability drawbacks.
The reason that this more global type of corruption occurs is due to another problem with using a write-back cache.
These write-back cache problems are a common cause of data corruption.
Management expects earnings of RUB100-120bn for FY10E, present but diminishing pressure on NIM in 2H10 and net write-backs of reserves in 2011E.
Thereafter, a strong earnings recovery should be triggered by reserve write-backs and supported by NIM stabilisation.
