Mostly, the stuff in the papers i don't fully understand is the specifics of the photo lithography, low-level circutry (like connector, signal driving details, and transistor workings in detail), and how the ECC and redundant algorithms works in detail (how it calculates data). I'd say i've got a pretty good understanding of the higher level architecture and workings of SSDs, and do a real effort, like you say, to not let go off things i don't get right away in more in-depth papers. Edit: i think this reflects a bit in my long ONFI rant on the first page of this thread

personally, i don't think you understand what you don't understand, i tried to help you see things which seemingly you don't, yet you just treat them as if they're just small irrelevant stuff, and you go on.
you don't seem, to leave yourself aside and look without prejudgment on what is happening outside,
and i've told you this already in different ways though it passes next to you and it's a shame.
seems like you already have an opinion on how things should look and showing you something else just interferes with your way of thinking.

i don't think you look deep enough inside yourself.

hopefully, you'll let these words sink in.

Different from earlier suff i've done, this will be with a linear QD stepping of 1 from QD 1 to 32. This is low to medium "parallell load", and will capture the relevant range for desktops and most kinds of workstations.

I'm looking for results from single HDDs and SSDs, and arrays of HDDs and SSDs. Basically any storage type. The more diversity i get the better. Anything from a 10 year old 5400RPM PATA drive, to a first gen JMicron SSD, to a velociraptor, Intel SSD, and 2-8(+) SSD/HDD arrays.

Results will be posted later as nice sorted graphs and diagrams in a dedicated storage/SSD benchmark thread I'll make.

Here's the config, i've included a txt file with info:
Attachment 105130
It will take about 20-25 mins to run and give me 128 datasets/points.
Post result files (csv) with the naming described in the info file in this thread (for now). If you do runs on multiple configurations, you can include multiple csv files in a single zip file with your username (and possible a general description of content).

Any results are greatly appreciated, since this won't be possible without collaboration, and nobody else are doing anything simelar of this detail and work size and sharing results (to my knowledge).
EDIT: it would be great with a comment on what you think, and if you're in, so i can see if there's any interrest in this or if i should just leave it.

Good morning,

Hey Gullars, long time old buddy.

I remember I got a lot of good tips from you for getting my Vertex 30GB, soon a couple of years ago. I've killed that little poor thingy now and need a new SSD soon.

I've been looking at Crucial RealSSD C300 64GB, and it seams to be one the best deals for a good SSD right now. Would you recommend hitting on this or wait for Intel G3 or other good SSD that would arrive soon?

If I have to wait, then I want to try some CPR on the Vertex. I've been booting from HDD in a couple of days as a temporary solution, and can't bare it for a long time. I was puling, pushing (and rubbing) the wires inside the HDD-bay and BIOS can't find the Vertex after that. I checked the connections and interface, they look OK, but still looks dead. Is there any good tricks to find out how dead it really is?

guy's you just seem to happen to have a big ego,
at least some of us do seem to pay attention to what is being said,
respecting others, is not a bad way of behavior, rather then lick them upside down with pretty words...

WTF? Can someone please tell me what this guys problem is?
Coz I sure as heck can't see how the tone of his posts would be justified :confused:
