Any difference between a 5400RPM hard drive and a 7200RPM hard drive when you use a USB2.0 external enclosure?

I think the 7200 one spins a lot faster.

err, what i meant was, am i wasting money by using a 7200 RPM drive in a USB 2.0 enclosure when a 5400 RPM might xfer data just as fast?

I know what you meant, it just needed to be said, that's all

I don't know I don't have a USB 2.0 card

But I do have a WD1000JB (7200RPM 100GB 8MB cache) in a firewire (Oxford 911)/ USB 2 (ISD300) external enclosure. I use it via firewire, 30MB/s sustained transfer across the disk.

Yes. USB 2.0 has a theoretical burst speed of 60megs a second. Since the fastest IDE drives can transfer data at 20-30Megs a second you are not limited by the USB 2.0 bus. Also, a 7200 RPM drive has much faster access time which will improve performance. There will always be latency issues with USB though. You will see an appreciable difference in performance going from a 5400rpm drive to a 7200rpm drive even on USB 2.0. the faster the drive, the shorter the life, the hotter it is, the more vibration, and the more power is required. Make sure that the enclosure can meet a fast drive's power and heat requirements.

IDE drives are way faster than this nowadays. The newest from WD can do 56mb/s at the start of media. There are reviews of the available external drives on the web so it may be in you may want to look at them.

I believe the speed is limted by the partictule bridge ur using, I hear the ISD300 (in system design 300) isn't very fast. But even the Oxford 911 chipset seems to be limited to 30MB/s. I've seen there is an Oxford 922 bridge (firewire and USB) which is quite a bit faster than the ISD300.

But anyways using the drive in my firewire enclosure is like having an internal drive.

where did you buy your enclosure? i bought a firewire enclosure from CompUSA a few months ago, and while it is great, it has this annoying rattling sound when it leave it running? do you leave yours running, and does it make any rattling noises?

thanks.

Improved seek times WILL help with repetetive hits to the drive. External drives work great as scratch disks.

see maxtor's ext hd:
usb 1.1 model uses 5400rpm hd
usb 2.0 model uses 7200rpm hd
firewire model uses 7200rpm hd

I have this case it does'nt have a fan so its super quiet. Its basically an aluminum shell with a power supply and a the circuit board with the bridges on them. Its easily able to dissipate the heat generated by the drive.

I do leave it on but the drive spins down after a few minutes of inactivity when I"ve got it hooked up via firewire. When I had it hooked up via USB 1.1 it would stay spun up all the time but it was still fine. Doesn't make any rattling sounds except for the sounds of the HD when seeking

usb 2.0 model uses 7200rpm hd

I have a 40 gig maxtor 3000le external usb 2.0 hard drive and it is a 5400 rpm drive.

 

[Kingofcomputer]

I should say
only the LE model uses 5400rpm because it's usb 2.0/1.1 only, mainly for the usb 1.1 users.
The DV and XT models use 7200rpm, fireware/usb 2.0/1.1, mainly for the fireware and usb 2.0 users.
