    Write Cache Enabled?

    What are the advantages of having write cache enabled on one's hard drive??

    I run a "stand-alone" P.C.
    Xp Pro
    512MB RAM
    40 Gig hard drive
    Cable Connection

    "Tweaked" to the max!!

    Thank you for any insight...........be well..........

    Many disk devices provide enhanced performance through the use of an onboard cache, which provides read-ahead caching for data that is being read from the disk, and write-behind caching (or delayed writes or "lazy" writes) for data that is being written to disk. In some cases, it is important for data to be written to the physical disk immediately, and not retained in the disk's onboard write cache to be written later during an otherwise idle moment. This prevents loss or corruption of this data if the disk or controller (wherever the write cache is implemented) suddenly loses power, for example.


    That said, it would appear that having write cache disabled, would protect your data from loss or corruption if in the case of a power surge or an outage were to occur.
    Because the data is not being written into the cache, but instead taken straight to the platter.

    When enabled disk I/O performance may improve because it is being sent to the "buffer" or cached portion of the drive. The large the cache, I would assume the better the performance, until the cache fills up.


    Does that make sense?
