Storage: my eSATA is transferring slower than USB??
upgraded firmware
by djbeema - 6/27/07 9:07 AM In reply to: Firmware upgrade will help by MadCrackenI upgraded the firmware like you did, and now it's getting gaster speeds, but not as fast as you've put down. I only get like 42mb/s burst
what's the new firmware version?
by vannguyen0 - 6/27/07 9:13 AM In reply to: upgraded firmware by djbeemawhat's the new firmware version?? i have yet to upgrade because it will only work on an xp machine... i have vista installed. i'm trying to get my hands on an xp machine... but want to know if the firmware upgrade is higher than 40.0A.
Do not use eSATA bracket
by vannguyen0 - 7/5/07 10:33 AM In reply to: what's the new firmware version? by vannguyen0Ok... so after talking on the phone with Seagate... they said not to use the eSATA to internal sata bracket. There's some weird stuff they cannot account for with that bracket. If you want to achieve the drive's full potential... you will need to get a true eSATA controller. I didn't like that answer... but I caved and went out to my local Fry's and got a PCI Express x1 eSATA controller (SI3132 chipset). Sure enough... it worked out for me. I had a Foxconn 6150B motherboard and was using a bracket. I was getting 30MB/sec sustained transfer rate and the drive was erroring out after waking my computer up from sleep. Connected it to the PCI Express x2 eSATA controller... I get a sustained transfer rate of about 49 MB/sec and it works just fine after waking up from sleep.
SATA drivers update
by MadCracken - 6/28/07 6:16 AM In reply to: upgraded firmware by djbeemaIsn't that an update for your SATA drivers?

Check the content of that link before installing anything. I found it by looking up drivers for the P5WD2 on support.asus.com.
What cable?
by acaurora - 6/30/07 2:31 PM In reply to: Firmware upgrade will help by MadCrackenHi, I just got the 750 ... and this eSATA cable I bought from Frys is a total piece of crap. I have to really push hard for it to actually stay connected... with HDTune I was getting about 50Mb/sec initially but again with having to hold the connector in is NOT the way to go for me. Can you tell me where did *ALL OF YOU* get your eSATA cables that WORK? (Online links would be handy) I dont want to have to make a dozen trips to different computer stores to try out eSATA cables...
got mine on amazon
by djbeema - 7/5/07 10:24 AM In reply to: What cable? by acauroraJust do a search of eSATA cable. Frankly I'm wondering if my cable is maybe the problem. I'm not really sure how or why there would be different types of eSATA cables, but it could be. I just got one that was a good price and looked decent, but it had no packaging that described anything really.
eSATA cable

To get the rated speed...

SATA to eSATA for max speed
by MadCracken - 6/28/07 6:05 AM In reply to: To get the rated speed... by Papa EchoMy 79MB/s burst and 40MB/s average was from the FreeAgent to my Western Digital 120GB IDE HDD. I do believe you would need to work from a SATA drive to get the full speed (300MB/s).
When I get some time I'll try to use an older IDE drive on a SATA converter and see if it improves anything. I do believe the max speed for IDE is 133 as opposed to 300 for the SATA, but my guess is most of the slow speed problem comes from the conversion from one standard to the other. If anybody has tried that already (or simply has a SATA drive), please let me know!!!
I AM using SATA
by djbeema - 7/5/07 10:10 AM In reply to: SATA to eSATA for max speed by MadCrackenMy internal drive is a Seagate 300gb sata drive. So that shouldnt make a difference.
eSata woes
by hubert99 - 8/2/07 4:48 PM In reply to: SATA to eSATA for max speed by MadCrackenI just bought FreeAgent Pro 750GB USB/1394/eSata unit yesterday, looking forward to faster backups and faster large file transfer. I do some video editing and 3 - 10 GB files are not unusual. My primary interest was eSata - USB2 and FireWire are ok, but......
This thing flat out sucks. I read these postings, tried the firmware upgrade, and no joy. See www.precise.ca/esata for test results. I thought after the firmware upgrade it started to look pretty good, but then tried my real world test - transfer 2 large .avi totalling 3.3 GB. Took 2:22 on USB2; 2:04 on FireWire, and an astounding 12 minutes and 44 saeconds with eSata......that's after the firmware upgrade. I was so puzzled I ran HD Tune again, and totally different results - 2.5 MB/sec min, max, avg AND burst. I don't know where to begin to look at this point.
System is a 4 year old Shuttle SB65G2 with on board sata support - I have a 160GB Seagate Sata as my main (and only) harddrive in the box. I'm connecting to the FreeAgent with one of those adapter dealies that connects to the Sata connector on the main board and out through the case to an eSata connector. Drive seems to work ok, and seems to be recognized, but sloooooowwwwww.
Any ideas?
Thx.....Randy
Internal HDD speed
by MadCracken - 7/7/07 4:11 PM In reply to: To get the rated speed... by Papa EchoOut of curiosity, would you guys mind posting your internal hard drives speeds so we can compare?
Please use HD Tune so we start from a common basis and list your internal hard drive type (IDE, SATA, magnetic tape?!), average speed and burst speed and same for your FreeAgent.
Because after messing around with my FreeAgent on a SATA to eSATA bracket, I get: 45MB/s average, 82MB/s burst.
My IDE drive gives me: 52MB/s average, 91MB/s burst.
I also ran HD Tune on a laptop (VAIO with Intel T5500, 1GB RAM, 80GB HDD) and got: 32MB/s average, 92MB/s burst. Not really sure it's comparable since I don't really know how laptops work.

What exactly do you mean by "Because after messing around with my FreeAgent on a SATA to eSATA bracket..." If this boosts rates, maybe you could elaborate so I could give it a try?
Found a possible answer to this problem

In this link, he mentions that with an internal SATA port, the mere act of adding a SATA to eSATA bracket and second cable can be enough to reduce the SATA signal strength to a point where SATA II (3 GB/s) speeds cannot be achieved. He jumpered his drive to SATA I (1.5 GB/s) and that made a big difference. This explains why buying a separate eSATA adapter works better. It's apparently not Seagate's fault at all (the drive in the above article is a WD). It seems that the onboard SATA connectors often just don't have enough grunt to drive the bracket/second cable properly. I wonder if anyone makes a bracket that has a built-in signal booster?
