3XCL4M4t10N: For a different take upon the word gay, i beg to differ.

That is not a small file. Nor is it random writes. Nor is the queue depth or cache taken into account.

Would be interesting to see what the power envelope amounts to in different scenarios.

According to this guys:

https://www.linux.com/learn/benchmarking-performance-tis-omap5432-board


OMAP5432 EVM is capable to achieve over 130 Megabytes/s on seek and read through the SATA,
Which is around 1Gbit per second.

But I think they hit the maximum limit of the SSD used for this test.

I have a question. How difficult/what would be required to get the pyra to be a SATA device? For example, let's say I want to boot a computer from the pyra, using it as a HDD or Disk Drive by plugging it into a SATA port on the computer. Or maybe emulate a custom disk drive, such as one used in a video game console?

That would be pretty difficult. But if your computer supports booting from USB mass storage, that would be the easiest way of using a Pyra as a boot device.

ED have to learn to close the camera iris.
Its horrible!!! Every picture is with that little sharp area. Thats not good for product pictures.

@ED: please try to take them with iris (Blende, du verstehst schon) over 10~14.
So the whole thing will be getting sharp.

Perfect would be to take the highest setting (maybe 22?), because you are not taking pictures from hand and with bad light.
ISO 100, Blende 22 = World happy

That does not work on my kitchen table with only LED lighting with an older camera and without tripod, which is where I did take the picture (I was at home, not in my office)

Besides, that's only technically better, as you want to see the whole product - from an aesthetic point of view, having a nice depth-of-field is nice.

I also usually dislike pictures where everything is sharp, as that's unnatural (your eyes also have a depth-of-field), but yes, or showing a product, it makes sense.

But here the reason clearly is low light and older camera. I could've taken a grainy picture with a higher iris value, which would've made everything more blurry...
That's why I took two pictures.

Are you seriously complaining about how the picture is taken? *sigh*

If you thought that it might make future photos better and you cared enough... why would you not? Would you rather not say anything, on purpose? That'd be mean...

 

[Wally]

If ED catered for everyone we wouldn't have any products, just pictures and ideas.. Which is why I ask!

*blinks* That's a good reason for ED to be selective as to what feedback he acts on, but it's not a good reason not to provide feedback, nor is it a good reason to discourage people from providing feedback.

That does not work on my kitchen table

Sketch some ideas for a device.

Blender will show the final product.

Design a board.

Put some chips on the board.

Then put everything in an oven.

A cooling system is required.

No, no ... With a sink !

Fork some projects.

May our journey finally bring us to the finish line

My external SATA housing only uses one USB3 cable for data and power, and I currently have it plugged into a USB2 host port delivering (I assume) only 5V at some amps, and that seems to be able to power my full-sized 3.5" hard discs just fine. Maybe my USB2 PCI card actually supports USB power at higher voltages though, I dunno.

Nope. External housings have a step-up converter to generate 12VDC from VBus (5VDC). Almost all (normal) Desktop SATA HDDs have the rotor connected to 12VDC and the logic connected to 5VDC.
Afaik, eSATAp drives may be powered from 5VDC, so the cable shown above on page 1 *may* work for eSATAp drives, but will most likely not work for desktop HDDs

 

[Kippykip]

Wait, does this mean I can connect a internal desktop harddrive into a pyra?
That's fucken sick!

Yes, but there is no way to directly power it from the pyra. There were some housings with eSATA + external PSU, no idea if they still exist.

 

[lukey]

Many 2.5" HDDs only need 5 Volts.

That's why I/we used the term "Desktop HDD" (which are 3.5").

One of the rules of taking pictures is: Never ever go over apperature 8. The picture will get blurry due to light bending.

Fine, but USB2 without any USB power extensions limits the current to 500mA. Step that up to 12V and you're talking somewhere around 200mA to power the rotor, before you even consider the logic or the stepper motor. I have USB SSDs that need a Y cable to provide enough current, yet this thing runs off a single USB cable, which surprised me slightly.

 

[TrashyMG]

It only provides regular SATA, you will likely need an external power supply which are fairly easy to get.

Honestly with a battery powered device I'd expect it's best to use externally powered drives even with USB3 drives.
