- USB 1.1 Hard drive transfer rates
- Posted by latichever on February 15th, 2004
I have a Dell Inspiron 7500 with USB 1.1.
I'm thinking about adding a usb hard drive that is usb 2.0 but
backwardly compatible to usb 1.1.
(I wouldn't be able to use a usb 2.0 adapter card because I want to
remain connected to my LAN. My network adapter card is pcmcia and has
a bump on top of it and the usb 2.0 pcmcia adapter cards also have
bumps so I couldn't use both at the same time. The bumps on the cards
would cover the upper pcmcia slots.)
I mostly don't care about the slower usb 1.1 speed since I'd mostly be
using it to store stuff and not to run programs.
But if I'm downloading files will the usb 1.1. hard drive be able to
keep up with my dsl connections, i.e., be able to transfer files that
are coming in at about 1 mbps per second at most.
Alternatively would I be able to set it up so that I would write files
directly to my faster internal hard drive and then have them
automatically moved to the usb drive?
Thanks.

USB1.1 hard drives get around a megabyte a second.
Maybe a little more if lucky.

I'm curious how often you plan to be downloading directly to the external
hard drive. If not too often, it may pay for you to download to internal
hard drive and then move to external hard drive. I have usb 2.0 ext hard
drive. If I download 20 songs, I'll do it to a folder on internal hard
drive, then cut and past the folder to the ext hard drive.
Mostly I use ext hd for storage/backup and move big files (sometimes 3-5 gb
folders of photos for example) to it. I guess usb 2.0 is helping my speed
here.

USB 1.1 is 1.5 mega bits per second, USB2.0 full speed is 12mbit and USB
hispeed is 480mbit/sec (apparently). You shouldn't have any problem saving
straight onto external drive I think.

Does your laptop by any chance have firewire? I bought a maxtor onetouch
that has usb and firewire. I use the usb 2.0 on my desktop and the firewire
on my laptop, can't really tell any speed difference. I do notice a lot of
difference when I try to use usb 1.1 on my laptop to connect. It's at least
three times slower.

I can do what you suggested, download to internal hard drive and then
off load to external. But if the usb 1.1 can keep up with my internet
connection, which is less than 1 mpbs per second. Why wouldn't I be
able to go directly to external hd?
I'm planning on getting the LACIE 80GB USB 2.0 HD 7200RPM. It seems
like good bang for the buck ($115) and within the foreseeable future
I'll have a new computer with usb 2.0.

Does the 7200RPM help me out at all? Although I'd guess the difference
between 7200 and 5400 is irrelevant for what I'm talking about.
Ideally, I'd like to find a way to connect my network adapter pcmcia
card along with a usb 2.0 adapter, but the bumps on the cards seem to
make it impossible to have two connected at the same time.

Yes usb 2 can be used with usb 1.1 and 1
average USB 1.1 transfer of 700mb = 18-20mins
average USB 2 transfer of 700mb = 2-4 mins

replaced a defective Inspiron 7000 that I bought new. That one cost
about $3k in 1998 for a pentium ii. But it was one of the first to
have agp graphics and a usb port and dvd player.
The great thing about Dell is that they were never a problem in fixing
a problem and even replacing the computer. The bad thing is that there
were problems. A chronic problem was the hinges that broke several
times. Hinges are laptops weak points and the Inspiron series has some
of the weakest.
Back then, they included a three years warranty in the price. Now
extra years are a la carte.
