Western Digital USB 2.0 external HD speed problems...
It's a 160 GB / 7200rpm -
http://westerndigital.com/en/products/wd1600b008.asp Setup went perfect however I can't seem to get the speed where it should be. I am formatted as NTFS, the USB 2.0 is a PCI Adaptec DuoConnect with 3 USB 2.0 and 2 Firewire ports (I have nothing in the other ports yet). I run a benchmark program on my internal Western Digital and get 33 MB/sec read write. Excellent. Run benchmark's on the external USB 2.0 drive and get Read 10MB/sec and Write 8315KB/sec Is this it? Should I not get like 33 MB/sec? I need to edit video and thought the USB 2.0 would at least be as fast as my internal. I installed all the latest XP Pro service packs, system is completely up to date on HD drivers. Also installed the latest Adaptec USB 2.0 card drivers (Enchanced Host Controler). I just bought the drive and can return it, but Western Digital tech support can't figure it out. All they suggest is download the latest drivers and that is what I have done. Any other options? Does it sound like there is a problem or is this all a USB 2.0 external drive can give? The system is a P4, couple years old and PCI slots should be fine I would think. Unless there is different speed PCI slots. Any help would be great...thanks!! Frank |

I need to edit video and thought the USB 2.0 would at least be as fast as my internal. Nar, even a firewire external is a bit slower than an internal, depending on what type of benchmark you use, how it moves the data etc. I installed all the latest XP Pro service packs, system is completely up to date on HD drivers. Also installed the latest Adaptec USB 2.0 card drivers (Enchanced Host Controler). I just bought the drive and can return it, but Western Digital tech support can't figure it out. All they suggest is download the latest drivers and that is what I have done. Any other options? Get a firewire one instead. Does it sound like there is a problem Hard to say without knowing which benchmark you used. http://www.xbitlabs.com/articles/sto...0gb-ext_4.html has some benchmarking data on the 250GB version, see what you get with the same benchmark software and configs. or is this all a USB 2.0 external drive can give? Thats well down on what some of the reviews have got. But not if you are using small block sizes in the benchmark. But again, depends on which benchmark you used. The system is a P4, couple years old and PCI slots should be fine I would think. Yeah, should be. Unless there is different speed PCI slots. There is, but thats unlikely to be the problem. Any help would be great...thanks!! |

Unless there is different speed PCI slots. Any help would be great...thanks!! Frank Yeah, that's seems about half of what would be reasonable. I have almost the same setup as you. 'Cept, I'm running a WD 80JB with 8MB cache through a USB 2.0. I'm getting 24MB/s throughput using Diskspeed 32, whereas my internal RAID 0 is getting 56MB/s. I also have an internal Seagate(old) IDE ATA 33 for my other OS(dual boot) that gets what your WD 160 is running at(9MB/s). But Rod is correct, FW will run faster even though USB 2.0 supposedly has a faster burst speed(400Mbs/s vs. 480Mbs/s). So, I recently ordered a FW external enclosure and will probably put another DVD writer in this USB enclosure. If you're using Sandra as a BM program, you'll get lower values. Try DiskSpeed 32, ATTO, and the one Rod suggested. Do you have the Intel Application Accelerator loaded(UDMA)? What's your CPU speed? Also, keep in mind that whatever your drive is rated at(ATA 66, 100, 133, etc.), it'll usually run at less than half of that on the average in everyday use with normal setups. Ron |

Yes, that would be my ICH4 SB wouldn't it? ICH4 should be able to do 32MB/s on read and 28MB/s on write. Well, at least with the c't testdrive it does. IOW, I did have it hooked to my internal chipset, It appears that some MoBos, next to the internal USB controler also have an extra PCI USB2.0 controller added to the configuration: IT7-MAX2 with VIA controller and GA8IHXP with a NEC controller. but still only got low twenties. Make sure that it is on the ICH4 and not some added PCI USB controller. If it is then perhaps your drive's USB-IDE convertor may be the problem. And yes, I do have the Enhanced Controller Hub drivers for USB 2.0. And, according to who? I need to read that. c't, a german magazine. Btw, before the MoBo chipset included USB2.0 controllers came about they initially thought that the USB-IDE convertor chips were the limiting factor. When the MoBo chipsets appeared the drives suddenly did better than they did on the add-on PCI interfaced USB chips from TI, NEC, VIA etc. So, I recently ordered a FW external enclosure and will probably put another DVD writer in this USB enclosure.

I was under the assumption that any USB 2.0 capable device could be hooked into any USB port and would automatically be routed through the Enhanced Controller. In any case, according to the properties tab under System for my external USB HDD, it is, in fact, running as a 2.0 device and not 1.1. Btw, I have an Abit BD7-II R mobo. The point may be moot, however, since I've just received my FW box and now am getting 34MB/s throughput. So at least THAT's working. Thanks for you input. Ron |

They obviously wouldn't get in the low 20 MB/s if they were USB 1.1. Btw, I have an Abit BD7-II R mobo. I don't have any offline info on that. Doesn't appear to have been tested by c't.
