There is a post over at the Homeservershow site testing the new storage spaces feature on the beta of Windows 8. Storage spaces is a feature that allows for pooled drives and parity protection of data. Essentially, this gives the ability to retrieve your data even if one drive fails. Parity solutions that currently exist include Flexraid and Unraid among others.
As you can see in the post, the writer is not impressed with the write performance of storage spaces as currently implemented.
You can see the numbers on pictures on the site, but the summary includes:
As you can see from the benchmarks below, the performance is still terrible in most tests. It got worse on some tests, while others got a bit faster. The one that is most important to me is the continuous write performance and that was only marginally better. All in all it is still a disappointment in terms of performance and does not perform on par with its sibling, Server 2012. The thought of getting slightly better than flash drive performance tells me that this not for serious users.
Of course, write performance in parity drive systems has never been a strong point. With all of its advantages, for instance, one of the great weaknesses of Unraid is the write performance of the system unless you use a cache drive which gives away the redundancy of the data until the cache drive writes to the array.
