Next Generation SSDs Delayed Due To Vista
PoliTech notes in a journal entry that "Vista is the gift that just keeps on giving." "Speaking during SanDisk's second-quarter earnings conference call, Chairman and [CEO] Eli Harari said that Windows Vista will present a special challenge for solid state drive makers. 'As soon as you get into Vista applications in notebook and desktop, you start running into very demanding applications because Vista is not optimized for flash memory solid state disk,' he said... 'The next generation controllers need to basically compensate for Vista shortfalls,' he said. 'Unfortunately, (SSDs) performance in the Vista environment falls short of what the market really needs and that is why we need to develop the next generation, which we'll start sampling end of this year, early next year.' Harari said this challenge alone is putting SanDisk behind schedule. "We have very good internal controller technology... That said, I'd say that we are now behind because we did not fully understand, frankly, the limitations in the Vista environment.'"
TFA doesn't go into much detail - by "not optimized" do they mean that Vista pages frequently, and thus would wear out the SSD rapidly? Or is it possibly something to do with sustained read speeds?
It greatly upsets me that they view this as a question of optimization.
Seek speed is nice, but it's only one aspect of SSD technology. Heat is another, and for a large segment of us the noise generated is the dominant feature. The HD is the only piece of the machine standing in the way of silent operation, and unlike power use or speed that's something that can affect the owner all day long even when they're not actually using the machine.
Holding up silent drives because they aren't quite fast enough is just disheartening. :-( I'm guessing for others, holding up cooler drives is equally sad.
rage, rage against the dying of the light
The interesting thing is the Ingo Molnar has said outright that none of the current Linux filesystems is GOOD ENOUGH for SSD's - he has his hopes on BTRFS to save us in the longer run - and the Linux filesystems are a damn-sight better at it than Vista...
Intriguing how Linux was already the best, and yet working on improvement when the competition hasn't even considered the problem yet.

It's not "bull". Microsoft fundamentally changed the storage architecture in Vista, making it very wasteful in many respects (battery life, CPU usage, drive thrashing). This *might* have been worthwhile if it offered a significant performance increase, but it doesn't. XP's storage architecture is better in almost every way when it comes to real-world usage.
The main problem is that MS is very secretive about proprietary code in their driver stacks, including storage & file system. You can't really blame SSD manufacturers for MS's complete lack of documentation.
Yeah, this was what I noticed the very first time I had started using Vista.
To clarify, the reason for most of it is at least threefold:
SuperFetch, Windows Search Indexing, NTFS Defrag.
I've found that disabling these will cut down on disk access significantly. Especially SuperFetch seem to be a big culprit -- it's "intelligently" loading files to RAM (pretty much any file, not just executables) if it thinks it's about to be used this time of day. For everything but the most regular computer usage patterns, you see how ridiculous of an idea that is. I decided to start disabling that system service after I had noticed it was trying to cache an incomplete ~100 MB file that was being downloaded by a P2P application to RAM. WTF, I was never going to open that file until it was done! I can think of dozens of cases where that prefetcher will be wrong, and I'll prefer saving my hard drive life time in that case.
Beware: In C++, your friends can see your privates!
He's got a point. Vista even introduces that "Dreamscape" stuff where the screensaver draws off your graphics card to do 3D rendering the entire time you're away.
It even moves the shutdown button elsewhere and put a standby button in its place.
Negligible for each PC but adds up to a lot of unnecessary power draw.
