Microsoft: Windows 7 is faster on SSDs, with two caveats - 05-06-2009, 07:24 PM
I find page 2 more interesting.

It tuned the upcoming OS to run faster on SSD drives. Microsoft Corp. today gave a strong, though qualified, endorsement for running Windows 7 on PCs equipped with solid-state disk (SSD) drives, saying it has tuned the upcoming operating system to run faster on the still-emerging storage technology.
At the same time, Microsoft admitted that it has not solved two lingering problems that can cause SSDs -- mostly lower-end, older ones -- to perform sluggishly or even worse than conventional hard drives.
Out of the box, Windows 7 should install and "operate efficiently on SSDs without requiring any customer intervention," Microsoft distinguished engineer Michael Fortin wrote in a posting at the Engineering Windows 7 blog.
Users of Windows 7 -- the Release Candidate 1 became available for public download today -- will experience the full benefit of SSDs in areas where the storage technology shines.
Small chunks of data can be read about 100 times faster from an SSD than a hard drive, since an SSD doesn't require a rotating disk head to be physically repositioned, Fortin wrote. SSDs will also read large files such as videos up to twice as fast as a hard drive does, wrote Fortin. Many SSDs will also write large files more quickly than a hard drive, especially when the SSD is new or empty.
The first generation of SSDs introduced mostly in netbooks two years ago were largely a disappointment, because they were slower and pricier than expected. But performance gains, as well as falling prices, have many PC makers excited anew about SSDs. Asustek Computer Inc.'s new S121 netbook has a 512-GB SSD that will run Windows 7 when it becomes available.
However, Fortin said that Windows 7 users could experience freeze-ups while writing small files and see overall performance slow down over time, depending on the quality and age of the SSD they're using. The freezing problem is caused by the "complex arrangement" of memory cells in flash chips, he said, as well as the fact that data must be erased from cells before new data can be written to them. And unlike most hard drives, few SSDs today include RAM caches that can speed up performance.
