External Harddive Transfer Speeds

Postby velocirafter » Fri Apr 09, 2010 5:13 pm

So I bought a SATA Harddrive (320 GB, 5,400 RPM, 8MB cache) and a seperate hard drive enclosure . The enclosure claimed to be USB 2 but the tranfer speeds are really poor, somewhere around 1Mb/s. Would I be correct in assuming that the problem is with the enclosure and not the HDD.

Are there any command that I can run or places to check to see if it is being picked up as a USB 2 device?

...oh i should mention that it is powered off usb, it needs to be connect to two ports.

Welcome to Linux Mint
Well, This is not the answer, but a recommendation, I also had issues with a external HDD that I bought for Back up purposes. I found that USB transfers were slow at best, & ( No matter the OS or machine, as I tried it on several ,3 ) It was not the HDD either, I guess it was the interface controller,in the enclosure. Well how did you figure this out , you ask. Answer = the box I purchased came with only USB cables, & the power cord ( outlet type adaptor ). The box had other ports, firewire, ( which I Did Not Try ) & E-Sata. I went to the Local retail store & purchased an E-Sata connector Cable. Transfer speeds were simply amazing, almost like writing to the internal drive ( it still takes about 30 sec for the OS to recognise the drive , probably due to the size 1.5TB ) but after that all is fine. I think I was not getting the full benefit from the USB interface. I haven't switched back to the USB again.
So if you can get a cheap enclosure that will support E-Sata , that is what I recommend.
I hope this gives you some ideas, Have A Good Day.

Checking usb (usbview) status..
--the standard is lsusb in the terminal..

Apart from some convenience, I don't know why anyone would want to use a usb (-->hard drive interface) connection translator device to manage their hard drives for backups or otherwise

If it's for a storage repository, such as video, graphics audio or other media, then a NAS solution is the cheaper/more expandable and better choice (which you now see usb external hard drive packages/hardware platforms) being used as: examples HP or other brands media centers, in a 2-->4 hard drive small case

Almost any old bare-bones computer, small case or not will do
--just supply a hard drive interface or a network connection (Ethernet) and go; after making the connections work correctly (network) or other wireless ? etc..
