Windows 7 disk transfer performance - post your pics


Recommended Posts

It's all relative really.

The hardware and the interfaces are much faster than the 3.1 days but we are also pushing far more data which tends to negate much of that speed bonus. (+7 now right ;) )

This is a very stupid test.

Why are you comparing copying a file to the same hard drive, and then doing the same test to another drive and saying that copying to the other drive was faster? Of course it's going to be faster.

It's not a stupid test because it gives a real world performance of sustained large file transfer as long as the conditions that i posted are kept to. eg. file must be over 2gb in size/wait to atleast 3/4 of the way through the transfer before recording the speed, file copy is on the same disk and not from one disk to another.

Of course some people are posting results from one disk to another but i dont mind if it keeps them happy as long as they dont mind posting the disk to the same disk result as well using the conditions from my original post on this thread. Better than not posting any results at all, atleast it's helping me find out what disks are the fastest in this test.

If you can suggest any real world performance test (not synetic) which is better to show large file transfer speed please post it and then we can use that instead.

The best test of all would be for every one to use the same large file copying from disk to the same disk and time it using the same os and that would be completley accurate to show which disk/disk's raided have the best large file copy performance but that might not be possible/to much hassle for people to do and that is why i asked people to post using this test.

(4 Seagate 500GB 32MBcache in RAID0)

Making a copy of a iso file in the same folder. I cant wait until windows calcule time remaining because the overall copy take about 3 to 5 seconds. Tis is fasteeeeeeeeeer than Vista, in Vista i cant go over 170MB/S.

My lite notebook with small 160GB 5400RPM also go faster than Vista, much faster.

That seems very fast even though it's 4 drives raided, what exact model of seagates are they. Are you sure you did not run the file before and it was stored in main memory/cache as my one vertex drive gets the result below if i run it a few times where it would normally get 70MB/sec. Could you please test and post the results again rebooting your system and run the file once and wait to 3/4 of the way through transfer before recording the transfer speed. Also if you could post your raided raptor results, that would be interesting. Thanks.

Thanks. Could you tell me the exact model number and size of the seagate?

Straight off the box:

320GB 16MB SATA HD

ST303204N1A1AS-RK

Identifies in 7 as ST303204N1A1AS when not in RAID.

EDIT: I am now getting 140MB /sec transfers with RAID 0

Thanks. Are you saying that when you raided the two drives you got 140MB transfer rate using the exact conditions of the test i posted instead of the 37MB for one disk you got before or do you mean that you get 74MB when copying on the same raided disks and 140MB/sec when copying from the raided disks to another drive while you got 65.5MB before?

Could you post a pic of your results showing the drives raided making sure it is recorded 3/4 of the way through the transfer of a file more than 2gb and that you reboot your PC and make sure the file is only run once after rebooting so it is not stored in main memory?

I already took them out of RAID and placed the Raptor as my OS disk for now. I will try RAID again after I get my hands on the RC.

79 folder to folder and 143 disk to RAID

OK, here is the lowdown an all three disks. Model numbers in the pic. I think I'll keep the Raptor as my OS drive:

First pic is the Raptor

Raid definately seems to double transfer rate speeds on both mechanical disks and ssds.

Taken from MSDN Blogs :

"Earlier, I made note of the fact that our new levels, 6 and 7, were added to recognize the improved experiences one might have with newer hardware, particularly SSDs, graphics adapters, and multi-core processors. With respect to SSDs, the focus of the newer tests is on random I/O rates and their avoidance of the long latency issues noted above. As a note, the tests don?t specifically check to see if the underlying storage device is an SSD or not. We run them no matter the device type and any device capable of sustaining very high random I/O rates will score well."

This seems to be to reason your disks still score 5.9 in WEI raided as the drives that get higher scores must be capable of sustaining very high random I/O rates and even though your transfer rate has doubled higher WEI scores depends on high random I/O's/reduced latency and not transfer speed.

This is my hdtune random i/o scores :

I tested in the Beta, to transfer 150GB by LAN with Gbit between one computer with XP (sender)

So the receiver (W7Beta) received at 50MB/s. I have no s/shot but its mostly close to the writing top of my HDD so its fine lol

Er, you have'nt followed the test condition of waiting until atleast 3/4 / near the end of the transfer before recording your result. Please can you post your results again with this condition met, thanks.

Mine gets this at the start of the transfer but averages out at 70mb 3/4 way through the test.
