@EvilDragon already announced, that there was a problem with the last mail batch and that he will send another batch.Unfortunately, I haven't received an e-mail either. Checked the spam folder, too.
I ordered end of January 2018. By the way, I'm No. 1103 according in the numbers image thread (https://pyra-handheld.com/boards/threads/the-numbers-image-thread.77461/page-42#post-1430331). Although generally the numbers image thread is not fully linear to the order history due to overlapping cancellations, in my case a direct association seems possible as I was the one that came in "fast forward to Saturday afternoon" in week 91 (https://pyra-handheld.com/boards/threads/weekly-pyra-preorder-stats.78477/post-1430408). Thank you levi for keeping track
OK. In that case (which the included pictures appear to confirm) I'm wondering what the discussion about the power lines means since a SATA II connection doesn't carry power for the device anyway. As far as I know the only connection that carries power is eSATAp (though, as I referred to, a lot of eSATA devices aren't eSATAp devices and don't expect power from the connection anyway).It's SATA II but not eSATA, @EvilDragon didn't check the differences before writing the technical specifications. See @hns' earlier post in this thread: https://pyra-handheld.com/boards/threads/its-software-this-time.99105/post-1675571
Originally, it was planned to use an eSATAp jack instead of that custom USB 3.0 jack solution. It wasn't possible to buy them anymore because they went out of production, though. However, the adapter still provides 5V via USB 2.0.As far as I know the only connection that carries power is eSATAp
Yeah, but the adaptor doesnt have a buck convertor to provide even the 3.3V let alone the 12V. Now 2.5inch drives never need 12V, and most of them are okay with 5V only, but the adaptor doesn't give you a SATA power connector even.Originally, it was planned to use an eSATAp jack instead of that custom USB 3.0 jack solution.

I would say something more like this :Yeah, but the adaptor doesnt have a buck convertor to provide even the 3.3V let alone the 12V. Now 2.5inch drives never need 12V, and most of them are okay with 5V only, but the adaptor doesn't give you a SATA power connector even.
Cheapest way round it as I see it is to buy a PC power supply brick that you screw into desktop systems, except you don't screw it in anything. Leave it on your desk and you'll have SATA power connectors coming out of your ears.
Because 5V is the only voltage that is universally available on eSATAp. To quote Wikipedia:Yeah, but the adaptor doesnt have a buck convertor to provide even the 3.3V let alone the 12V.
There are only two versions of this port. Most laptop computers do not have 12 V power available, and have an eSATAp port which provides only 5 V. Desktop computers, with 12 V available, have a port with two additional pads, placed against the plug's "horns", which provide 12 V. Some manufacturers refer to these ports as eSATApd, where d stands for "dual voltage". Some devices, such as 2.5-inch drives, can operate off the 5 V supplied by laptop eSATAp ports. Others, such as 3.5-inch drives, also require 12 V; they can be powered from a desktop eSATAp port, but require an external 12 V power supply if used with a laptop computer. This can lead to confusion if users are not aware of the distinction.
I am quite aware of all that, and there was never any confusion on my part about it. What I wondered about, specifically, was that, since the adapter appears to have a regular internal SATA port, why would anyone expect it to furnish power since internal SATA ports never furnish power to the drive? The only kind of SATA port that furnishes power to the drive is eSATAp. You can't tell the difference between a powerless eSATA port and a powered eSATAp port by looking at the outside of the port, so some might expect an eSATA port to furnish power when it actually didn't. Since the port appears to be a regular internal SATA port, there are no power lines to be missing power. There's no need to explain that the power lines are missing on an internal SATA port.Wow - there seems to be a lot of confusion around the SATA piggy backing off of the USB 2.0 port by using a USB 3.0 physical port.
Frankly, if you're confused as to what this is - don't worry about it, you don't need it in order to use the Pyra.
What it is: A USB 3.0 physical port has more data lines than a USB 2.0 port. The port on the Pyra is a physical USB 3.0 port jack, but only has the USB 2.0 data lines being used for USB. The -other- data lines on the physical USB 3.0 port are wired to the SATA connection on the SoC. This way, with a simple adapter, the Pyra can directly 'see' a SATA device connected to these data lines. This is -not- a USB to SATA adapter. It is the Pyra being sneaky and using a more complex port to double the functionality of the physical space the port occupies.
Does that help?
That's a nice way to suggest that it's a mess. Can hardware tinkerers not use proper eSATA?There are a few things on the Pyra that are there simply because it is fun for hardware tinker oriented people to play with. SATA lines hidden in an otherwise innocuous USB 2.0 port, a microUSB charging port with serial coms, etc. Nobody should be worrying too much over the SATA data lines and that, "it isn't proper eSATA". It isn't there to be a traditional eSATA. The important bits are there so we can have what we need to tinker with.
There isn't much difference between SATA and eSATA other than the shape of the connector and how much power can travel in the cable, depending if it is eSATAp or just regular eSATA. Power differences with eSATAp are handled with the Pyra adapter. lacking "proper" eSATA isn't a big deal to me as regular SATA cables are easily found and eSATA is a kind of fading out and I can foresee it getting harder to find these cables due to USB C.That's a nice way to suggest that it's a mess.

It would be more convenient if the port on the adapter were an eSATA port. However, since it wouldn't have power either way, and internal SATA to eSATA cables exist, it's far from the end of the world. My combination USB 3 / eSATA drive dock includes an eSATA cable that I won't be able to use with the Pyra, and I will have to get a SATA to eSATA cable instead. So I have a little added expense, but I will be able to use the dock with the Pyra if I want to.That's a nice way to suggest that it's a mess. Can hardware tinkerers not use proper eSATA?
