Console.WriteLine(drive.Name); if (drive.IsReady) Console.WriteLine(drive.TotalSize); } } }

Manipulate an Archive in memory with PHP (without creating a temporary file on disk)

How much faster is the memory usually than the disk?

I’m surprised: Figure 3 in the middle of this article, The Pathologies of Big Data, says that memory is only about 6 times faster when you’re doing sequential access (350 Mvalues/sec for memory compared with 58 Mvalues/sec for disk); but it’s about 100,000 times faster when you’re doing random access.
