Imho windows/whatever boottime is relatively irrelevant, especially since normal computer spend quite a lot time doing BIOS initialization code - which obviously isn't going to be affected by a SSD drive at all.

But application startup time is relevant enough - I'm generally annoyed at anything that takes more than half a second to start. I can forgive that for larger applications, but it still annoys me. If Visual Studio would go 1-second startup time and firefox would go down to a few hundred miliseconds, I'd be quite happy :)

Carol: use "start <whatever>" to do that - check "start /?" from a cmd.exe prompt, it can do lots of useful stuff.

How do you get it to do all four at once? I have tried BAT and CMD files but it loads the first app and only opens the second app when you close the first app window etc. ?

This is how I did it (without a batch file): https://www.donation....msg154388#msg154388

Thanks yes - that works - don't ask how long it took, I gave up waiting and went and cooked dinner ;)

Today I did remember the link that was mentioned in my previous post about using SSD as cache for RAID systems:

http://tweakers.net/...als-cachinglaag.html

It is in Dutch, but your friend Google will be able to translate for you.

Hmm, interesting - I wonder a bit if the caching is also meant to speed up writes on a RAID - after all, proper raid adapters have a decent amount of cache-ram, which should be enough to rearrange writes and give nice linear write-bursts. But using the SSD to cache writes that would later be used for reads, that could be interesting - especially for database systems.

I now finally watched the video, and I was of course wrong wrt. ioDrive being faster than the 24 SSDs. Should've realized that 24 SSDs in RAID would mean a really fancy RAID controller :). I wonder which controller they used - 2GB/s data transfer rate is pretty impressive. With pci-e 2.0, it would have to be at least a 4x card, according to http://en.wikipedia....PCI_Express#Overview :)

Opening many programs simultaneously was probably chosen specifically to make the SSD RAID configuration look impressive. A more realistic benchmark for most people would be copying several large files from one area to another on a single drive. I suspect that would not be quite such a slam dunk for a SSD as opposed to a HD, regardless of configuration.

At AnandTech there's a very long, but very interesting article on SSDs:
The SSD Anthology: Understanding SSDs and New Drives from OCZ

Wow, very long article indeed - I'm at page 22/31 right now. Kudos to OCZ for actually listening up, and sacrificing some bandwidth to fix latency problems... might look less impressive on paper (and thus get flamed by people who think they have hardware knowledge), but the end result is a fast and usable drive.
