Speeding things up |

Having read all the reviews, the SSDs seem to be blazingly fast on read,
and quite poor on write. Thus if you are writing in your database, you may see little benefit. If you are mainly reading, then they'll whizz. It struck me that the answer for the manufacturers is to put in a few meg of cache ram for the writing. It would take the writes quickly and store it while the flash takes the age to actually write. For many applications, that would be enough to take a load of updates and move on, but obviously some may do larger writes than the cache, or too fast, and then they'd find the performance penalty. But the majority would simply find the disk was like a ram drive. /Matthew Jones/ | |

Do you have any time to perform the test Tim was proposing? |
