Can I use an external hard disk as RAM to improve my computer speed?
NO. Hard disks are much too slow. Windows already utilizes your internal hard disk when applications need more RAM than is physically present. That’s what the paging file is (Data temporarily written to the hard drive to free up RAM), and it doesn’t speed up your computer, it slows it down MASSIVELY. Reads and writes to a hard disk are exponentially slower than RAM access, just because of the physical nature of the devices (electronic vs mechanical). External drives are even slower to access than Internal drives because they’re further constrained by USB transfer speeds. http://www.terryscomputertips.com/comput… So you see, Ready Boost isn’t so great to begin with… performance is far worse than adding more RAM. But at least some Flash drives are fast enough to make the Ready Boost technology somewhat useful in specific circumstances. That’s why only some Flash drives are suppor
