I have a Samsung spinpoint f3 and i am trying to transfer some stuff to a usb 3.0 Goflex 1.5tb drive. I started at 325 mb/s and quickly stumbled to 14 mb/s.... I transferred the same data to a usb 2.0 drive and got 30 mb/s constant.

I have a gigabyte GA-Z68A-D3H-B3 motherboard. which has two usb 3.0 inputs.

Anybody know why im getting so slow of transfer speeds to my usb 3.0 drive.

I just tried to transfer a 20gb file and its started at 50mb/s and slowly went down to 20 mb/s (by the time it was 4gb in)

Not the goflex 1.5 tb. I know that is new. The drive that contains your files, samsung spinpoint, is that highly fragmented?

Ok that is the problem. 120 GB of music (comprise of thousands of 3-5MB small file as well as KB size album art) instead of one continuous 130 GB file. 15MBish is normal. How about the 20G you later send, is it also one continuous or comprise of many small files?

Yes it is...But why would i get 30. mb/s with a 2.0 usb and slower with a 3.0. even when i plug the 3.0 into a 2.0 slot it still have very low speeds. i was going to give my brother my 2tb usb 2.0 but its better than the 3.0.

The usb 3.0 high bandwidth allows for really fast emptying of the fast disk cache in the initial moment (burst rate), and leave the mechanically slow hard disk platter to transfer small files, requiring constant stop to seek new file. In contrasts, in usb 2.0, the mechanical hard disk also transfer at 15MBps but since bandwidth bottleneck restrict the emptying of the cache in burst at the beginning, the data in the fast cache linger and is transfered at the same time as the platter data to saturate the 30MBps, giving it a more average speed. Now, if you have larger continuous file, like a any file over say 0.3GB. Because there is little seek for small file, hard disk platter will rotate without stopping. usb 3.0 will not be a bottleneck because the interface bandwidth is greater than the hard disk output. On the other hand, usb 2.0 is bottlenecking the mechanical hard disk because of its limited bandwidth. In large file, usb 3.0 will be about 180 to 300% faster than usb 2.0. Find a continuous large file to transfer. I will be surprise if usb 3.0 is slower than usb 2.0.

Ok back with results. I transferred a 18.7 gb MKV single file from my 2tb Usb 2.0 to my internal samsung spinpoint. this took 10 minutes at a constant 35 mb/s.

Then i transferred the same MKV from my internal samsung spinpoint to my goflex 3.0 1.5tb drive. This was taking well over 45 minutes. Very Very slow speed something like 9.84 mb/s. So i cancelled it.

So i transferred the Same MKV from my internal samsung to my external 2tb 2.0 drive. This took roughly 10 minutes at the same 30ish mb/s.

I decided to copy a 20 gb music folder from my usb 3.0 goflex drive and transferred it to my samsung internal and was getting an average of 90 mb/s....So i found that the only way to transfer fast is from the external to the internal. I would rather it be the other way around...


Also i have two internal harddrives both 1tb (spinpoint and wd cavi) is there a way to use one to speed up the other. I think its called Raid 0 but it seems that you need an ssd? Any help in this direction would be appreciated as well.

Ok defragged all three of my drives. all said about 3% fragmented before. Completed the defrag and tried my test again.

Transferred a 15 gb mkv movie file from 2tb Usb 2.0 drive to my Internal samsung spinpoint. This transferred at 34 mb/s a slight increase.

Then i tried to transfer the same file to my Goflex 3.0 usb drive from my internal. Started off fast for about 2gb, then same thing went down actually even further then before i defragged to 8-9 mb/s. Took little bit over an hour or two. i dont remember exactly.

Transferred the file of the Goflex back to my spinpoint at pretty good speed 60ish mb/s. didnt take more than 10 minutes.

Tried to transfer smaller but more complicated folder (as it has a bunch of Flac Files= 10mb total of about 10gb). Again started off amazing and by 2gb it was going way to slow.

I ended up transferring all my music (140ish gb) back to my external 2.0 2tb usb drive and had an average of about 35-40 mb/s.

This 3.0 drive is not all it is cracked up to be.

Also i was wondering about speeding my internal drives up. I have two 1 tb internal drives. Can i run these in Raid 0 and will it make a difference? and if so any kind of walkthroughs/tutorials to help me get my drives in this state that would be great.

It seem there is a problem with mechanical read of the spinpoint. Can you get a S.M.A.R.T of it.

So it was 1 internal drive and now you have a raid0, correct? Lets not complicates things further because if one of your drive have a problem, you raid0 is likely to suffer to. I will run S.M.A.R.T on single drive, the one that is slow. Go through the stats for issues. Also, since it is the internal drive that is slow, I also think you should put it on another port and update bios/driver (if available).

ok well i just disabled raid0, changed the drive to different sata port. and reinstalled windows 7. Its just about done. so when done i will install all motherboard drivers, graphics driver, and update windows. then how do i run S.M.A.R.T? is there a program to do this? or is it built into windows system? im on windows 7 ultimate x64

everything look ok. On the safe side can you also bench the usb 3.0 drive? Don't worry about s.m.a.r.t for usb drive, you wont get a heath stat for it. and the health of the internal drive are ok right?

Internal transfer (samsung) to other Internal (wd) speed of 81 mb/s (3.8gb music folder)
Transferred back Steady at 200mb/s until about 3/4 way done dropped to a low of 120mb/s

Transferred same 3gb file from Internal 2 (wd) to usb 3.0 with constant speed of 45-50mb/s

Transferred back at 1gb/s for about 1 sec or 2 seconds went down to about 500mb/s then dropped to a low of 450mb/s

I can see the transfer rate to the usb 3.0 drive is the worst of all performance. Is write cache enable on the usb 3.0 drive? Enable it if it is not. I think most likely there is a problem in the usb 3.0 implementation. Nearly there. There can be foure potential problem. 1. the hdd in goflex is bad and writes slow. 2. the go flex enclosure is bad and writes slow. 3. The usb 3.0 driver is causing the bad performance. 4. Firmware. I suggest update and reinstall usb 3.0 driver. Update goflex drive firmware. If that is not working, I think we should get a second opinion on what is wrong. Although I cannot see any other problem. If my dianogstic is correct, the provided that you have warranty, return the goflex drive.

Anyone reading this thread have a second opinion?

Alright so this is kind of weird. Transferred a 18 gb mkv file from internal (wd) to 3.0: This has gotten me my highest transfer rate yet 120 mb/s for first 6 gb then dropped to 85 mb/s for about 8 gb and finally went to 63 mb/s for that last little bit.

When i transferred it back. well i got around 12 mb/s even slower alot of the time. infact it is still transferring

I think you can cancel the transfer. If you enable write cache on usb 3.0 drive and 12MBps is from wd to usb 3.0 and you reported eariler about 9MBps from spinpoint to usb 3.0. I am pretty sure the usb 3.0 is not writing as it should. Call up the manufacturer for exchange or return to shop in DOA period.

No. From WD--->Usb 3.0 =120mb/s
From Samsung--->Usb 3.0= 12mb/s

From Usb 3.0---->WD= 12 mb/s
From Usb 3.0---->Samsung=90 mb/s

Samsung-->WD and WD-->Samsung is fast right. Then the conclusion is that the problem is random and cause is inconclusive. Sorry, I am also puzzled here. Need someone with better skill here. I am going to find a top expert and send them a message to ask them for help.

The transfer speed between the internals is pretty fast and constant: 65ish mb/s
and then as i stated above from WD-->usb 3 fast opposite slow Samsung-->usb 3 slow opposite fast...

I appreciate all your help Pyree and returning for all my questions.

I asked Hawkeye22 and got this reply:

I didn't read trough all of the posts, but some F3's have a firmware bug. Samsung has released a firmware update to fix the problem. have the OP check the samsung web site for a list of effected drives. If his drive is on the list, he will need the firmware update.

You may want to ask him directly.

Alright thanks Pyree, i searched for a couple hours about the firmware problem. It seems i have the latest most up to date firmware for the F3. Tried the transfer test again First from
3.0-F3=slow
F3-WD=Average (65mb/s)
WD-3.0=Slow
WD-F3=Average
F3-3.0= slow.

I also have a macbook pro with firewire 800 port, so i plugged a firewire adapter (that i previously bought for this drive from Seagate).
FW800--MBP=70 mb/s
MBP--FW8= 70 mb/s

Lastly I tried on my Girlfriends Asus Laptop (3.0 enabled with same drivers as my rig).
3.0--Asus= 75-85 mb/s (little fluctuation but generally pretty steady at 80mb/s)
Asus--3.0= 74-99 mb/s (started out slow eventually got fast then slowed down a little)

Could this may be not a problem with a drive at all rather the mobo's 3.0 ports. on newegg some of the reviews say the the usb 3.0 port is "hit and miss".

Any insight would be great especially if someone has had the GA-Z68A-D3H-B3 mobo.
