More Information

I read a review of an external drive that ran thru E-sata here...Tom had said "you could run your OS off of it"

My question is, Does the E-sata express card bottleneck the speed at all?

i was looking at this one http://www.newegg.com/Product/Prod [...] 6839150001

Im unsure since an PC card would have a direct connection to your MB....I'm not familer with express cards and I'm a bit unsure on how this works.

Your speed will be the speed of your slowest component.

SATA is 3GB/sec, but if you're connected to a 33MHZ PCI bus you won't reach it.

That said, I boot Linux off a drive connected to an eSata port just fine. But that eSata port is connected to the ICH7R

well i have a DELL e1705 with an express card slot...what speed is the express card slot transfer and how does express card slots transfer to and from my laptops motherboard?

Apparently at 2.5GB/s

How Dell chose to connect your slot to your motherboard - I have no idea.

Thanks sruane...so it looks like it will be bottlenecked by atleast .5 GB's...

I noticed i have a great framerate on games now, but this 5400 RPM drive sort of kills that experience...I get stuttering when i 1st shoot a weapon or if it's been a minute before i last fired...picking up new weapons and reloading(new animation) or anything that needs to load from the hard drive..makes the game stutter.

maybe a external drive will solve this, or maybe shipping it back to dell to upgrade to a 7200 RPM drive would be better...i need to make a decision soon tho, as my 20 days is almost up.

so if the express card connect's to the pci express bus...and say it operates at 133mhz??...whats the proper MHZ to get a full speed on an E-sata port?

I don't know the answer to your specific question, but the easiest improvement you can do is to add RAM - at least 2GB. Sounds like you only have 128MB, or something.

I have 2GB of RAM running on a T7200...a 7900GS 256bit/256ram video card and framerate isnt a problem...i think it's the HD...as it only slows down when it accesses the HD.

I thought it would atleast load everything into RAM so it wouldnt have to keep accessing the HD...is there a setting outside of the game to make sure my RAM is holding things it should, instead of continuing to access my HD?

btw, thanks for ur help...seems like noone else has an answer for me so far.

If lowering the graphics settings doesn't help, then all your left with is disk I/O. Assuming your drive isn't fragmented then I guess you're right - you need a faster drive.

which Reverts back to my original question....If i do get an 7200 maybe even an 10k RPM drive, and i use E-sata thru the Express port, will it be fast enough?

It seems that i also run thru Ich7r (according to Sisandra)...but perhaps im looking for someone who has tried this...I was going to email tom, but figured i'd try here 1st....I'd really like to hear from someone who has some tried this before.

in the meantime, I'll give Dell a call about this poor HD performance

I have two 1OKrpm drives in RAID 0 on an ICH7R and its extremely fast, although I don't think that's an option in a notebook.

well i finally got rid of the slowdown during game play....when the hard drive lit up to read (load a new weapon,animation,etc..) it would sort of pause the game for about .5-1 second...this was due to speedstep!

my processor was dynamically changing it's speed and when it went to finally increase (when loading something) it caused a slowdown in the game.

although im still not happy with 33MB/sec read speed...i can live with it....so speedstep was the culprit all along.

Im testing one more game now to see if this has solved all issues.

Set the control panel power option to always on and use i8kfangui to keep it cool. Might have to set the video card in advanced of i8kfangui to 10 offset to correct the temp to nvidia control panel temp readings.
In graw it takes ages to load the game on any hd / pc.

I am going to get a esata express card slot + 2x wd4000kd's in raid 0 for my e1705 + 7800gtx moded , just to get past the 45mb/s barrier.

I see one website list the sonnet as running at 100MB/s to 110MB/s
http://www.usb-ware.com/esata-expr [...] ess-34.htm
and this one at 140MB/s max but heck this is more than what I need and from 33MB/s or 45MB/s to 110MB/s is already worth it.

Man if only I can get a shop selling the fujitsu laptop hd http://www.tomshardware.com/2007/0 [...] index.html
