HD Tune running for a long time without speed drop off.

Hey I'm testing a Fantom External HDD to see where I should short stroke the drive at. It's been benching the drives read performance for a few hours. Right now, it's just past the half way point of the 3 gig drive, without a performance drop.

I do have Corsair link running for temps of components, but don't see it displaying the temps for that drive. I don't know if that could be messing with the bench. The disk is also allocated. Could that be messing with the reading? What should I do to bench this drive correctly for short stroking?

**Edit: This is what the capture looks like. Is it even worth short stroking the drive?

You should show the full window so we can see the speed.

If the usb interface(common on USB2 drives) is bottlenecking the drive, You will see the same speed across most of the drive(until it falls under the speed of the USB port.).

Short stroking works on drives via partition or other methods. When using the partition method, HD tune will not show it because it tests the full drive. Making a short stroked setup other ways will show.

The RED line is an old short stroke with 3 drives(about 1/3 of each drive in use). Blue was the 2 x 240's it replaced

You may have enclosure bottleneck.

I only say this because some of the faster drives on the market get up 180-200 megabytes/sec near the start. If the enclosure caps out at 112 then the drive will sit at that speed until the drive gets to section slower than 112megabyte/sec. Your min still seems excellent.

What is the exact model number of the drive inside that thing anyway?

I have had some off brand drives(Acom DATA). I think it had a western digital in it.

As a backup drive it was perfectly fine and I later swapped to a larger drive(2TB Seagate LP) and never had an issue aside of how cheap my e-sata cables had been.

I currently have that drive still and a WDC mybook(3TB). Both are just on for backups so they do not get allot of use.
