Windows 8 (storage implications?)

[Computurd]

So windows 8 will be available in a few hours for those with TechNet, and several hours later on the torrents, of course!
Gonna D/L off the technet and maybe see if there are any types of storage differences.

hopefully there will be optimazations for SSD for the love of christ, is there some coding changes in this OS? the WIN7 treatment was superficial at best. Cant wait to run a simple winsat and see what the differences are. I have a test OS on a 256 C300 and am going to install to a identical C300 and do some comparisons.

of course i would love to see others results as well, lets see what happens!

i thought that MS was putting out the redskin win7 with the universal UI option for windows8 being demoed and not windows8 yet

Where did you read this? I'm out of the loop.

I have a technet liscence, so I can see if it's up.

gah i may be incorrect here...this is the page.

what exactly does it mean by 'preview'?

[Computurd]

yeah i dony know either. its D/L now so we will find out shortly

[zanzabar]

what exactly does it mean by 'preview'?

its a pre beta, from what i gather its the post PC UI on windows 7, but im going to instal it and take a look

EDIT: doh! Computurd beat me to it

[Computurd]

got it installed...much different, but the internals look sevenish in some ways of course.

[odditory]

i'd be very surprised if there were any improvements to the way SSD's are handled in Win8 versus Win7, at least at this stage of the dev cycle. If any optimizations come then I'm sure it'd be later on.

I'm not all that sure what really could improve at the O/S level if we're already getting the full speed of the drive from Win7, I could see maybe extra user options for setting things like how aggressive TRIM is, or the ability to set extra paremeters like strip sizes when configuring software raid in Windows Diskmgmt. There is of course still that gaping feature hole which is TRIM being incompatible with striped arrays (both hardware and software raid), so while getting the feature implemented is complicated by Microsoft and hardware raid vendors having to work together, at least windows software raid - which MS has full control over - would be great if it gained TRIM support. This is really an area that MS could capitalize on with CPU's being more powerful than ever, and the hardware raid controller market continuing to taper downward.

OTOH I'm kind of expecting not much attention to be paid to enhancing disk I/O at least with any of the ideas I mentioned, as it seems the push right now is toward the lowest common denominator end user, its no coincidence that Apple is making boatloads off products tailored toward consumers/dumb end users and along came MS with the tiled Metro UI which first appeared on Zune to compete w/ iPod and then spread to Windows Phone, and will continue spreading as Microsoft-defacto on Xbox360, Windows O/S, Surface and whatever other devices they're working on. I'm sure I'll like Win8, but honestly my first reaction to Metro UI was "Fischer Price".

I downloaded last night, was thinking of putting it on a laptop.

Looks like a W7 with a new GUI from what I can see.

[mbreslin]

I was going to put this on a vhd, for those familiar with vhd can I make one on a raid array? And if so am I able to attach a vhd on a raid array during the W8 install process?

Thanks.

[NapalmV5]

no implications here

as far as alignment goes..

win7-103424kb

win8-359424kb

Looks like Windows 8 automatically detects SSD's and runs TRIM optimisations instead of defrag. (It can trim SF and Intel drives)

[Nizzen]

Nice find!

[Ao1]

It looks like MS have made a special version of the standard MSAHCI driver:

Driver Version 6.2.8102.0 (win8m3.110823-1455)Date: 21/06/06

I wonder if it can detect drives in a raid array.

Strangely, the W7 driver is also dated 21/06/06. It seems something went wrong there, there are several versions of it dated the same day.

I wonder if it can detect drives in a raid array.

To do what exactly? If the controller provides such data, it can, but what it can do based on it is a different question.
E.g. Areca provides some data about individual drives in an array, but I believe it only provides SMART attributes.
It can't do TRIMs if the controller and controller driver don't support it. It is above the disk manager level.

Very nice find on the defrag!

[Computurd]

yes excellent find! I havent had time to dig into this...

[alfaunits]

Tried it from inside a VM - no go (attached a physical disk). recognizes it as an HDD.

[Ao1]

You get a bit more info when a file is being xfered.....



You also get an option to copy a file path on the explorer tab:

[Ao1]

Whoa.....

I created a raid 0 array and it looks like you can TRIM the array using the optimizer

C drive - raid 0




This is the default raid driver that Windows 8 installed

[Computurd]

now that changes things quite a bit!
first thing to do i guess is to get an array into a degraded state...then TRIM it and see if it recovers performance, i.e it actually works...

we need to think of a way to come up with a test to see if it really works
that would be very exciting if it does!

[Ao1]

"fsutil behavior query disabledeletenotify" returns a 0.

I ran Anvils app and I got a "TRIM" hang when the loop ended. I tried to disable TRIM via the fsutil command to see if the TRIM hang disappeared and it returned an "access is denied" error.

I'm not sure how else I could check (hIOmon does not work on Win 8) but it really looks like TRIM is working.

[Wendy]

Win8 TRIM confirmed working on Vertex, C300, Intel 510, Vertex 2, and Vertex 3 on a SATA analyzer.

I then used a bus analyzer to check the Revo X2. The command is sent, but it doesn't get through to the Revo X2.
Revo has its own RAID drivers, so that doesn't mean it won't work on the mobo's RAID solution, but it's not something I can check at the moment.

[Computurd]

wendy, was it working in raid?
