I attended my favorite storage conference last week in Silicon Valley, File And Storage Technology (FAST). This is the foremost gathering of corporate and academic researchers and practitioners in the ...

The caching of content from disk storage to high-speed memory is a proven technology for reducing read latency and improving application-level performance. The problem with traditional caching, ...

With the introduction of the solid-state Flash drive, performance came to the forefront for data storage technologies. Prior to that, software developers and server administrators needed to devise ...

I have a Dell PE2590 with a PERC5 handling a 6 disk RAID5 array. Write-back caching is enabled but it's defaulting to write-through. This is obviously murdering performance (writes = 30Mbps vs 300Mbps ...

Going through the BIOS menu afterward I noticed that the default for Advanced Options > Drive Write Cache is "Disabled". Does this mean that all the drivex in the box (which are attached to the ...

Flash storage provides significantly more performance (IOPS and throughput) and lower latency than hard disk-based media. Of course, flash comes with a higher price tag – up to 10 times more than ...
