The Windows 10 "in place" update will also roll up your old Windows installation and save it in a folder called Windows.old (assuming there is room).
Graham I'm not sure exactly what's going to happen: the Windows 10 "in place" update may not behave the same way as the test version, and it will vary according to the amount of disk space available.
Gotta love that copyright protection system they have in place (update: taken down again).
However, flash memory does not support the in-place update which is in direct opposition to efforts to securely delete sensitive data from storage.
However, existing in-place update approaches either introduce significant I/O overhead or cause low update efficiency in erasure-coded storage systems due to the consistent update of parity blocks.
We also show that with careful design of aspects of implementation such as free-space management, in-place update can be improved by around an order of magnitude over a naïve implementation.
Our experiments with large volumes of web data show that re-merge is the fastest approach if large buffers are available, but that even a simple implementation of in-place update is suitable when the rate of insertion is low or memory buffer size is limited.
When applications want to overwrite existing data, SSDs do not perform an in-place update of the physical pages that contain the old data.
Unlike Flash memory, these new technologies will support in-place updates, avoiding the extra overhead of a translation layer.
In-place updates are often used to overwrite the existing data rather than append the new data so as to ensure the data access efficiency.
