My ISOstick is VERY slow to load boot images, regardless of the micro SDHC card used. I first used a SanDisk general purpose 32GB Class 4 speed rated card and then upgraded to a SanDisk Ultra 32GB Class10/UHS-1 speed rated card, both formatted FAT32 as received. Both result in the same boot load times and the load times are much slower than booting the same image from a CD/DVD. This is with the latest ISOstick firmware (1624).

 

Booting Paragon Partition Manager from the Laptop's CD/DVD 24x/8X drive takes 3.25 minutes.

Booting Paragon Partition Manager ISO (252 MB) from the ISOstick takes 9.5 minutes.

Booting other larger images such as WIndows 7 Pro takes up to 20 minutes from the ISOstick, again with either card used.

 

I re-flashed the ISOstick with the same latest firmware (1624) and it made no improvement.

 

The computer is a Dell Precision Mobile 6600 laptop with 8GB memory and dual Intel Core i7-2920XM 2.50GHz quad-core processors.

 

Everything else works as it should with the ISOstick except for the abysmally slow speed. I'm wondering if the unit is defectrive in some way.

 

Any ideas/help appreciated.

 

Thanks,

Ed Ruth

Have you tried transferring files to/from isostick once in Windows (or whatever operating system you use) ? What's the transfer speed you get there?

An old computer of mine only allowed USB1.1-speed (about 150KB/s I got) when outside of Windows (thus in BIOS/DOS environment).

 

That's about the only explanation I can think of (besides flash cards with abysmal 4KB-size random-read performance).

I just ran copy to and from tests in Windows 7 using the ISOstick with the SanDisk 32GB Class 10/UHS-1 card and an old, heavily used SanDisk 8GB thumb drive. Prior to the tests I emptied the thumb drive and fully formatted the micro SDHC card in the ISOstick using the Windows 7 Pro defaults (FAT32 and 16KB allocation unit size). The results still show the Isostick as abysmally slow. Note that the laptop's drive is a very fast solid state drive so is definitely not limiting.  Here are the results using 8 files totalling 6.48GB in size which are the current contents of the ISOstick:

 

Copy from Laptop drive:

Thumb drive: 9.5 minutes

ISOstick: 13 minutes

 

Copy to laptop drive:

Thumb drive: 4.3 minutes

ISOstick: 11.5 minutes

 

I guess my next step is to submit a support ticket?

OK, now I really believe the ISOstick is defective. I just popped the 32GB Class 10/UHS-1 Micro SDHC card in an SDHC adaptor and inserted it in my laptop's SD card reader slot. Copying the same 6.48GB of files from the card reader slot to the laptop's drive took only 3 minutes compared to the 11.5 minutes (see previous post) when copying from the ISOstick.

8 files worth 6.48GB means this is all sequential reads/writes. Isostick is limited to 12MB/s by the controller. The used flashcard could be even slower (also depending on protocol, not every device knows about UHS-1)

 

Copy from Laptop drive:

Thumb drive: 9.5 minutes

ISOstick: 13 minutes

 

Writing from SSD to thumb drive: 6635MB divided by 570 seconds means 11,64MB/s sequentially written. Slow thumb drive hehe

Writing from SSD to Isostick: 6635MB divided by 780 seconds means 8,50MB/s sequentially written (out of 12MB/s max)

 

 

Copy to laptop drive:

Thumb drive: 4.3 minutes

ISOstick: 11.5 minutes

 

Reading from Thumb Drive: 6635MB divided by 258 seconds means 27,72MB/s read sequentially, without SSD as write-bottleneck

Reading from Isostick : 6635MB divided by 690 seconds means 9,61MB/s read sequentially (out of 12MB/s max)

 

 

I guess my next step is to submit a support ticket?

So the SD-card can read at 36,86MB/s while isostick limits it to 12MB/s or slightly below.

The 12MB/s figure is from http://isostick.com/support/faq/

Fastest MicroSD cards can do about 90MB/s sequentially. Fastest USB sticks do 40MB/s on USB2 and about 250MB/s on USB3

( http://vr-zone.com/a...eeds/18840.html )

 

A Zalman unit takes 2.5" drives and would be able to get up to 300MB/s I guess on the V300 version, which uses SATA-2 (internal) / USB3 external)

Just for the record, although a large number of laptop's SD card readers (internal) are actually connected through an internal USB bus, it is not necessarily so.

In practice you may be subtracting (or adding with the Isostick) a USB bus bottleneck of some kind (not necessarily the specific case, mind you).

 

If it was a desktop I would suggest you to try the isostick on a different set of ports (some motherboards have two different controllers, one "better" and one "slower") but I don't think that the same happens on a laptop.

 

There is a known "performance hit" in XP (and consequently most probably on Vista and 7) when the FAT32 filesystem is used, but it should apply to *any* device, i.e. the USB stick should have the same kind of slowdown, see:

http://www.msfn.org/...d-on-usb-stick/

 

What is queer is that if I get the data right:

 

 

Copy from Laptop drive:

Thumb drive: 9.5 minutes

ISOstick: 13 minutes



Copy to laptop drive:

Thumb drive: 4.3 minutes

ISOstick: 11.5 minutes

the write speed is all in all "comparable" 9.5 to 13, whilst the read speed (which normally is MUCH higher than write one on normal USB sticks) is much faster for the stick 4.3,  but not for the isostick, the 11.5 are very similar to the 13 minutes.  :unsure:

 

Usually the read speed of a SD card is roughly double the write speed.

 

A class 10 SD card is can have as low as 10 Mb/min transfer rate:

http://sdcard-speed-...icles.r-tt.com/

 

but if it can make it in three minutes, it should mean that yours is a faster one,  the whole experience sounds "queer", so it is very possible that the bottleneck is the actual theoretical 12 Mb/min of the controller. :dubbio:

Well, based on all the replies, based on the 12MB/s Isostick controller limit, perhaps it is not an issue with the raw read speed for coventional copies (NOT boots). Then my problem goes back to the fact that the ISOstick boots ISO images 3 times slower than the same boot from my 24x/8X CD/DVD drive. The FAQs state that the ISOstick can be as fast as a 82x CD drive or 9x DVD drive. That same FAQ states that; "Combined with almost no seek times, ISOstick is much faster than a real optical drive." There has to be someting wrong with this stick.

Hi eruth ,

 

As  bblaauw has pointed out, the speeds you are seeing are on par with what should be expected on isostick, given its ~12MiB/s limitation. That said, it should still be faster than a physical CD during boot, so that is a bit odd!

 

If you don't mind doing some testing, please load the desired ISO into your isostick's CDROM, then install and run ImgBurn. Select "Create image file from disc," choose the isostick CDROM as the source drive, and select a destination on a fast (ideally non USB) drive. Make sure read speed is set to MAX in the first drop-down (the second drop-down is for Audio and isn't relevant for this test). Click the start button at the bottom and wait for it to finish. When it's done, in the log window at the bottom of the screen click File -> Save As, save it somewhere, and then attach it to a reply here.

 

If you have multiple ISOs that boot slow, please repeat the test for each one.

 

Thanks,

Eric Agan

:cheers:

Hi Eric,

 

I will download ImgBurn, run the tests tomorrow and post results right after. I need one clarification. When you said "please load the desired ISO into your isostick's CDROM" did you mean load an actual .ISO file via the ISOstick's boot menu and then boot to Windows to run ImgBurn - or did you mean in Windows to copy the discrete files to the ISOstick CDROM that would be used to create an ISO file using ImgBurn? Sorry for the confusion here.

 

Thanks,

Ed Ruth

Sorry, I meant copy the ISO files onto your isostick's flash drive as per usual, then you can load them using ISO Manager (like the isosel boot menu, but runs in Windows).

Eric,

 

Ok, understood. I already have ISO Manager and used it to originally split/load the Win7 Pro DVD install image to the ISOstick. The other ISO files on the stick did not require splitting so just copied them directly. Thanks.

Eric,

 

I did not see how to attach the log as a separate file so pasted it here. I ran the test for all four images on the Isostick.

The first, second and fourth were written to the SSD in my laptop. The third was written to the 7200 RPM SATA drive in the laptop.

The laptop has two USB 2.0 ports and two USB 3.0 ports. I used a 2.0 port since that's what I have to use to boot from the ISOstick (BIOS does not support booting from the 3.0 ports).

Thanks for doing the tests.

 

10:14:33 Average Read Rate: 9,694 KB/s (7.0x) - Maximum Read Rate: 10,628 KB/s (7.7x)

10:16:16 Average Read Rate: 9,877 KB/s (7.1x) - Maximum Read Rate: 10,847 KB/s (7.8x)

10:17:50 Average Read Rate: 10,022 KB/s (7.2x) - Maximum Read Rate: 10,847 KB/s (7.8x)

10:38:41 Average Read Rate: 9,495 KB/s (6.9x) - Maximum Read Rate: 9,990 KB/s (7.2x)

The speeds look very good, exactly what I would expect from isostick under normal conditions.

 

So, I suspect it may be similar to:

An old computer of mine only allowed USB1.1-speed (about 150KB/s I got) when outside of Windows (thus in BIOS/DOS environment).

And doing a bit of math, you say it's about 3x slower than your CD drive which is 24x (CD) / 8x (DVD)...

USB Full Speed (the slowest isostick will negotiate) would be 12Mbit/s = 1.5MB/s, but some bandwidth is reserved and then there's packetization and other overhead, so you see about 8.7Mbit/s *max* in practice, or 1MB/s

3x slower than your drive's rated speeds is about 3.6MB/s, but an installer or livecd is likely doing a lot of random accesses so it would appear slower than that still.

 

If we can assume the actual performance of the real CD/DVD drive is 3x slower than its rated speed, then the numbers add up  :dubbio:

 

Do you, by chance, have a USB CD/DVD drive to test this theory with? I would expect it to behave similarly.

If not, I will toss something together so isostick can tell us if it has negotiated USB Full Speed to your BIOS. It may very well be a bug relating to how your BIOS initializes isostick -- it's not very likely, but it is possible! (Which would mean I can patch isostick firmware to fix it.)

 

Also, do you have any other computers to try booting on?

 

Thanks :cheers:

Eric,

 

It appears that as you and bblaauw said; my BIOS may not be properly initializing the isostick.

I switched my external Plextor PX-L890UE CD/DVD 48x/24x drive from eSATA to USB connection on the same USB port as before and booted Paragon Manager from it. The boot time was just over 9 minutes, only slightly faster than the isostick.

Also, using the same old 8GB USB memory stick as in the previous Windows read/write tests I created a bootable Paragon Manager and its boot time was just under 1 minute. However, the total size of the files on the memory stick was only 92MB compared to the 252MB image on the isostick. So, 1 minute for the memory stick, 9 minutes for the USB CD/DVD drive versus 9.5 minutes for the isostick.

I do have another computer, a Dell Optiplex 330; however, though it sees the isostick in Windows XP, it failed to recognize the isostick for booting (no iso menu, and "No boot device found" when "boot from CD" was selected) even after I disabled the internal CD/DVD drive in BIOS.

I can take the isostick to one of my client's offices and try it on a few different computers if you want but it does look like my laptop's BIOS is suspect here.

If you are going to try a patch to the isostick firmware, for what it's worth my USB 2.0 controller is an Intel 6 Series/C200 Series Chipset Family USB Enhanced Host Controller and my Dell Precision Mobile 6600 laptop has the latest Dell BIOS version A12.

 

Thanks

Ed Ruth

Eric,

 

I forgot to mention that if you are going to "toss something together so isostick can tell us if it has negotiated USB Full Speed to your BIOS", I'll be glad to test as needed.

The PLoP bootmanager (available as an ISO) can boot USB flash drives in an accelerated way. Ofcourse that might make isostick pointless as you might as well use a simple usb stick then combined with Syslinux and/or Grub.

Due to the unique nature of the isostick, perhaps the CD-emulation gets usb2.0 speed at the same time as the flash drive would get it once PLoP gets loaded.

Eric,

 

First, it still looks like the BIOS is definitely not properly initializing the isostick on the Dell Precision Mobile 6600 laptop.

My apologies but my previous times were not exactly accurate because I was including the time it took to actually see the first program screen on the computer. Then I noticed that the activity light goes out on the isostick and other media earlier than that. So I was adding times not relevant for the tests. Also, the times for the flash drive boot were not exactly comparable because I discovered it was a "minimum" configuration of Paragon Manager - so I rebuilt the flash drive with the full version which comprises 297MB, basically the same as the CD version and close to the isostick (252MB). Finally, I did test on another computer that recognized the isostick. Here are results which reflect only the load times from the media used:

 

Dell Precision Mobile 6600 laptop:

Flash drive: 25 sec.

CD drive 24x: 2 min. 0 sec.

Isostick: 8 min. 25 sec.

 

Dell Latitude D830 laptop (6 years old):

Flash drive: 15 sec.

CD drive 20x: 2 min. 35 sec.

Isostick: 2 min. 40 sec. (note about same as CD -why???)

 

Thanks,

Ed Ruth

Another "semi-random" thought.

Bootable *whatever* can (and should be) optimized on CD/DVD media.

The SAME approach has led to interesting results on USB sticks too.

 

See a few posts starting from here (this is about PE 1.x's):

Determining bottlenecks by tests:

1) file copying

2) operating system loading with a reference OS

3) operating system loading with your preferred OS

 

You've already done the file copying of step 1, and now are trying step 3 by loading Paragon CD-image.

I'd recommend you first benchmark loading times of a very-well-known ISO such as PartedMagic, and preferably also copy its files as well under Windows.

In other words, it's unlikely other isostick owners are able to replicate your results if sticking to a more obscure (Paragon) CD-image.

 

You've already demonstrated that isostick is faster on another system even with same flash card inside. Maybe that system defaults to initialising USB2 at fast speeds instead of USB1-speeds.

A sane operating system installation loads its driver files as early as possible so any file copying can benefit from the full bandwidth. However, at early stages still some file copying/loading might be done at the speed that BIOS configured the USB-port. Your 6600-laptop likely suffers from this issue.

Eric,

 

Any progress on resolving this issue with a firmware upgrade?

Sorry, no progress at this time. Thanks for bringing it to my attention again, I will try to get some test firmware soon to investigate this further.
