Credit card shaped 16GB USB sticks with engraved Bitcoin logo (Batch 1)

[Craynon]

I am Craynon
I'm not worried about them being legit, just wondering if they'd been manufactured yet or what stage they're at

[Teka]

Don't worry, Craynon vouched for him being legit.

The units have been manufactured and are being shipped out to me so they will probably arrive on Wednesday. If you have a any doubts about me not being legit you could always ask Tinua (His Order has been fulfilled and he has received 25 working units) . There were simply no updates to give out until today.

That's fine, just wondering

The units have arrived and will be shipped out tomorrow afternoon.

Cool, can't wait.

Do you have any idea what (speed) class the memory is?

Do you have any idea what (speed) class the memory is?

It is a USB device and should be Version 2.0 - you can see the contact so it aint 3.0 . And there are no "speed classes" - Version 2.0 varies, more on e.g. https://en.wikipedia.org/wiki/Universal_Serial_Bus ; the speed data of this device was not communicated and was not subject to this product as it is IMHO more a matter of design.

By the way I cannot imagine a usb 3.0 device to be this thin because all connectors I can find are quite well shielded and thus not thin enough.

[vv01f]

I personally think of putting several preconfigured wallet software on these ones  with additional information to give away to beginners (bitcoin-qt without wallet.dat but with a preloaded blockchain signed by me, brainwallet.org and bitaddress.org, vanitygen as "offline files", list of shops, links and some tutorials/howtos).

The memory will have a read/write limitation, regardless of which bus (USB) is being used.
USB2.0 has a max. data rate of around 60MB/s, but the type of memory inside the stick (I'm not sure what is being used) will have a performance limit.
If, for example, an SD card at class 10 is used, then the maximum write speed will be 10MB/s, regardless of the fact USB2.0 can hand a bandwidth of 60MB/s.

Sounds good, it would make a nice, small, gift.

I like to remaster my own live Linux distributions, so I'm thinking about putting a couple of them on their for personal/computer repair use, along with a version of Linux for using an offline Armory wallet.

Nice one, looking forwards to it!

Hey everyone.

Units have been shipped out. The EU and US units were shipped out via Airsure and depending on custom they should arrive within 2-7 working days. The UK units were shipped out via Royal Mail 1st class. I don't know about the class of the cards but I will test them out tomorrow and give you an estimate of what speeds you should expect.  If you need any more information send me a pm or reply to this topic.

Thanks,

Teka


edit: Bulk orders above 25 units are still accepted.

Read/Write speeds if any one is interested (using FAT32):

Read:  26.20 MB/sec
Write: 6.3 MB/s

Code:

READ

hdparm -t /dev/sdc
Timing buffered disk reads:  80 MB in  3.05 seconds =  26.20 MB/sec
Timing cached reads:   15096 MB in  2.00 seconds = 7554.25 MB/sec

Code:

WRITE

dd if=/dev/zero of=speedFile bs=1M count=1024 conv=fdatasync,notrunc
1024+0 records in
1024+0 records out
1073741824 bytes (1.1 GB) copied, 169.493 s, 6.3 MB/s

So I'd guess from a quick test that these are class 6 cards- pretty good

[Craynon]

Just received my card, looks very nice Thanks!

[Teka]

A quick update to EU and USA customers:


Your package has arrived in its destination country and should be with you shortly.


Thanks for the feedback Craynon and Openyoureyes.

To OpenYourEyes: Thanks for the performance numbers and some more information on the probable class of the card .

[vv01f]

Just some feedback on the thread:
The cards arrived yesterday in Germany, redelivery in the country also is done. AFAIK no problems at all.
Tested one of them for the speed question with H2testw v1.4:

Code:

write: 5,79 MByte/s
read: 18,1 MByte/s

Received my 2 USB devices also, had forgot I had asked them to be delivered to my work address and they had been lying there probably for some time so very happy with both the product and the seller.
Thanks!
