To jump in real quick since my comment seems to have revised the thread, I did refer to the 'average Joe' or typical user activity in which they will never (or may never) have reason to utilize high sequentials whatsoever.

c300 is 31-32MB/s on a good controller :)Quote:

one thing that is still overlooked here alot by people is the typical user pattern though.
when reviewers test load times, install times, etc, they are done with the disk usually with nothing else on it. NOT with an OS, or if they do (rarely) have an os installed, they only have the OS, and nothing else.
what about desktop gadgets, antivirus, mail, browser, media player, FPS measure, everest, etc? this is what typical users have
now lets look at my not-so-typical usage pattern (multimonitors FTW!)
i play almost all of my games windowed so that i can do other things at the same time.
so what was i doing last night?
i watched the first miner come out live streaming from CNN (in HD) from the mine in Chile while i video chatted with Tilt in Greece. I also had my media player up because i jam when i play, at the same time i was playing farcry2 windowed. i also had my email up because i leave it on as a matter of course, so that when i get emails i get that nice noise :)
now i also have several desktop gadgets that are running to tell me speed of my internets, the weather out, and the cpu/ram usage, and the system monitor.
so not necessarily normal usage but very heavy. YES i am running Kapersky, and several browsers so that i can keep an eye on the forums...
However, i can do this, lag free and i mean totally lag free. on the game, on the video from cnn while talking with tilt, and some music playing ever so lightly in the background.
Now, that is some heavy stuff there. And smooth as glass. everyone brags about how fast things load, etc...but what about how well they RUN once loaded?
where are the benchmarks for performance with that? i put up some example pics of me doing precisely what i told you tonight while chatting with tilt, to illustrate my point.
Now, the last pic i am showing you is of my disk read per sec activity while doing this. note the spikes. the graph is set at 70, not 100 for illustration purposes. now, look at the spikes in disk read as i do all of this.
the faster that you resolve those spikes (by having ultra fast i/o) the better your system will run. and mine is smooth as glass even under this load. the CPU and RAM arent being loaded very heavily, it is all in the disk I/O that is making it smoooothhhhh. most peoples systems would sputter and hitch and lag like crazy.
during gaming they say around 70 percent of access is sequential, so yeah, resolving those huge sequential read requests as quickly as possible is crucial to doing things of this nature effectively. that way the system can also do the other myriad of accesses that it is being required to.
BEWARE the "standard" tests. there is nothing standard about them. they are as far from real world as you can get. how many people set there and load games off a SSD with nothing else on it? or an OS with just a game and nothing else at all running? well, probably people who need SSD's with ultra fast speeds :)
*LOL i always love that the FPS is showing how many FPS i am getting to tilt in Greece :) )

@computurd: what drive(s) are you running?
five 30GB ocz vertex (gen one dinosaurs) on a areca 1880 controller with 4GB of cache. and for those who want to cry CACHE! i can tell ya i have also done this type of stuff easily with the 9260 (512mb) and the 9211 (no cache), the only constant is that they are all 6gb/s cards. yeah not standard stuff, but shows the benefits of these types of speeds.
another thing that is not being mentioned here is that 6gb/s raid cards have better latency, even with 3gb/s devices. there are many *previously* documented cases of guys getting .05 latency with intels, and c300's, on 6gb/s platforms. can your 3gb/s interface do that? hell no. now, once we get some more advanced 6gb/s drives out, and put them on 6gb/s controllers (and onboards, soon) then we shall see ultra low latency.
now, lets talk about some other things that are benefits of the 6gb/s protocol. all we are mentioning here is the maximum speed.
that is not seeing the forest because the trees are in the way.
there are many more important advances to 6gb/s than maximum sequential speed.
random access has been mentioned as what is most important. the 6gb/s protocol is way faster at random access than the 3gb/s. it is a matter of course that it will be better. that's why they do these things.
*Isochronous Streaming command Native Command Queuing (NCQ) streaming command to enable isochronous quality of service data transfers for streaming digital content applications
*An NCQ Management feature that helps optimize performance by enabling host processing and management of outstanding NCQ commands.
*Alignment with the INCITS ATA8-ACS standard.
now, NCQ is what drives random I/O to ever higher peaks. there is an enhanced instruction set for NCQ with sas/sata 6gb/s. this increases your random performance. also increases the reliability of write combining with SSD usage, so that you are writing more effectively.
also, Isochronous Streaming should speak for itself. this is awesome stuff here.
not to mention that the processors other components involved are faster than the 3gb/s counterparts, thus resulting in faster everything, random included :)
these are the advances that 6gb/s gives us. to say that it is not needed and not better is being misinformed. this is an entire specification, that has MUCH more to it than the fact that it increases sequential speed.
Computurd....
Gotta like your setup as i just ordered my 28" to enhance my 22" this morning...
yeah man i love multimonitor, been doing it awhile. even though i run windowed usually a game or browser takes up my whole second screen. i just pulled down the game a bit to show the browsers behind it.
I have four screens and have even experimented with using three and four at once, but that is a bit overwhelming even for a power user :)
the whole thing really opened up for me when one day my buddy said "hey run your game windowed so we can chat while you play"
increases productivity for sure.
playing with the sound mixer is key though so i dont get too overwhelmed with different audio outputs. i find my eyes can track three or four things at once, but my ears can only follow a few...so i put the music low, the game sounds in the middle, and the chat/video streaming at high. soemtimes have to cut out audio on a few things (like the miners for example)
strange that it works :)
so acard performance but nonvolitale and at a capacity that doesn't involve your first born.Quote:

TLC NAND might be able to deliver the capacity and price, although I’m not so sure about the data integrity. I’ve asked Intel if they would consider such a product.
I’m open minded on SATA 3.0. So far I’ve not seen anything of interest, but its early days and no doubt things are cooking behind the scenesQuote:
