NEW KomputerBay *1050x* 128 GB Card

[KB TechSupport]

Out of curiosity, KB tech support, if the internals aren't broken lexars, what internals are the komputerbay cards sporting?

>>The main component which is Micron NAND. Some of our cards carry the same exact Micron NAND.

Also on the description of the 128GB 1050x it says it's write speed is the same as the 1000x cards. The only difference is that the read speed is faster. Is this true?

128GB 1000X V2 (basically anything that was shipped from USA since last week, UK since this week and DE/Fr/ES/IT this week is all V2)

is: 90~100MB/s Write and 150MB/s Read

128GB 1050X is 100~110MB/s Write and 160MB/s Read



We are looking at 120MB/s Write speeds cards (1200X) early next month on a trial basis. Mass production will be looked into once these pass the tests.

I'm already getting over 120 MB/s in camera with Komputerbay 32GB 1000x (file write benchmark in playback mode, where most Canon tasks are idle). Actual recording speed: 109 MB/s at 24p.

FYI, 1000x means 150 MB/s, http://en.wikipedia.org/wiki/CompactFlash#Speed .

Just to chime in, I can't speak highly enough of the Komputerbay tech support team.  Fast responses and great answers to my questions!  They are not your traditional tech support that reads off an answer sheet, they actually know their stuff.  I have a new 1050x 128GB card on the way and I'll be posting up the results here asap!

[N.Mendes]

Can't wait for your tests all, i hope that these new 1050x are not "lottery" and are strongly reliable like a Lexar 1000x can be.. And thanks to KomputerBay for your quick and clear answers, i (and all of us i'm sure) really appreciate..

[senzazn12]

Thank you Komputer Bay Support for your clear answers as well. I bought a Komputer Bay 128 GB 1000X CF card last November and it still functions great. I guess mine was one of the good ones because when writing RAW video to my 5D3, it averages about 97-98 mbs. So I'll be happy to pick up a Komputer Bay 128 GB 1050X soon.

Thanks for the response! One more question though:

"The main component which is Micron NAND. Some of our cards carry the same exact Micron NAND."

When you say "Some of our cards carry the same exact Micron NAND.", which cards does Komputerbay offer that contain this chip?

Wow, this progress would be absolutly amazing!

I'm eager to order 3 of those 1200X ones.
I hope they will come before November to match our production.

This speed really has enough headroom to make dropped frames something of the past.. probably also good for a suitable 1080p30 and a 720p50 option.

[tronics]

For some reason the speeds at the beginning of the test were slower..not sure why..but
--It was nice being able to roll continuously with no problems for over 30,000 frames, thats 24 minutes!

What I have heard a warmup of 1,5 - 2 GB makes the 1000x cards somewhat faster or reliable.
This might be a myth. However it could be a possible explanation.

I'm so bummed I can't install ML on this card because of the 64GB+ limitation.

Anyone have any advice for 50D and MKII users? We don't have an SD slot to run / install ML from...

Buy the cheapest CF card you can find. Speed and capacity is irrelevant as you're only installing from it. You should be able to pick one up on ebay for under 5$ or borrow one from somewhere. You only need to to install once to set the bootflag. Then you can use your KB card.

Get a cheap 4gb CF card unlock the bootloader on that and then you'll be golden.

Thanks for responding.

I have a few CF cards all with proper ML installations.

So my procedure would be:

1. Install Fresh ML on another CF card.
2. Eject Card
3. Plug into computer card reader and copy files to PC.
4. Eject other card, plug in KB card, copy files into root directory.
5. Make card active via EOScard / MacBoot.
6. Eject Card - replace CF inside camera.
7. Turn on and *hopefully* ML loads

Does this sound right?

Just tried this process and it didn't work. Not booting from KB card. Can I manually add "EOS_DEVELOP" and "BOOTDISK" partitions? Are they hidden like EFI?

You don't need to move files at all... just move the magic lantern root from the RAR to your bigger CF card after you installed it and make sure AUTOEXEC.bin is in the bigger card so it can boot. Then EOSCARD it and done.

Still won't work. The 5DmkII can't see the .FIR file on the 128 gig 1000x or 1050x card.

That method you mention is not a problem with 32 or 64 gig 1000x cards.

I just finished doing some testing on my New KomputerBay 1050x 128GB Card.

A little disappointed as I have read others having flawless results. I could not obtain consistent Continous results at 1920x1080 24fps with global draw on or off. (Drop frames would occur randomly, some times 2 frames into the recording or some times 1000 frames.)

Here are my settings.

- Formatted CF card to Exfat
- Running ML off 32gb SD Card 95mb speed.
- Using ML v2.3 2013-July-17- 5D3 1.13
- Warmed up the card with 1GB files
- Tried recording at 1920x1080 24fps
- Tried Global Draw on & off
- Tried Memory hack On & Off

Here are some results which I got.

1920x1080 24fps Global Draw OFF Test 1



1920x1080 24fps Global Draw OFF Test 2



1920x1080 24fps Global Draw ON Test 1



The results were a downer, and the card was not consistent in performance at all.  (As shown above the results from Global Draw On is actually better than Global Off....weird...)   (Some times it would give me the green "Good to go" record setting approval at the bottom along with all the record dimensions and mbs per frame at 1920x1080, but when I record it would fail after few hundred frames.  So times it even fails at 3 fps... I have never gotten past 3000 frames at 1920x1080 with this card.)  I consider this as a fail in recording 1920x1080 continuous.

Finding a stable setting for this card.

Bumping down the Ratio:

I started to bump the ratio down from 16:9 to 1.85:1 and so on until 2.35:1

Unfortunately for me it was only some what stable at 2.35:1 .   Recorded at 1920*818  18049 frames. (that is 47.5GB) (Consistently recored 70mb per frame.) (I consider this to be a pass as I don't shoot documentaries...)

Bumping down the resolution:

After testing the ratio setting I put it back at 1920x1080 and started to test the resolution. 1920x1080 to 1856x1044 to 1728x972

Once again it was only some what stable at 1728x972 Recorded at 1728*972  18278 frames. (that is 50GB) (Consistently recored 69.8mb per frames)

(I consider this to be a pass as I don't shoot documentaries...)

Over View:

Over all the card itself for normal use is excellent, It can handle 6fps burst raw + jpg easily as well as recording video in h264.  As for shooting raw video I was hoping it could do stable continuous 1920x1080 @ 24fps and maybe even 1920x1080 @ 30fps. So I'm a disappointed that this card can not shoot at those settings.  I will look at the 64gb 1000x as a temp solution while I wait for their 1200x version to be release in  a month or so.

I hope the information helps and if anyone can recommend me proper settings to make this card work at 1920x1080 then please contact me.

(I would rather have this card work than to send it back.)

I can confirm that Lexar 1000x can do 1080P at 30FPS (32GB version). If swapping cards out is not a problem for you (I have a small Thinkpad and external) for the field, then go for it.

[alvink]

Woh it can do 1920x1080 @ 30fps for the full 32gb?  Hum if that's the case then the 64gb might be worth it. (dont know why but it seems that 32gb and 128gb aren't as good as 64gb even at the same 1000x.)

Any one else have 64gb 1000x cards that can do 1920x1080 @30 without any drop frames?

[alvink]

I made a video on how I'm testing the 128gb 1050x card.

Komputerbay tech support ran through a CrytalDiskMark test with me and we both got similar results 129mb read and 96mb write, from a 4000mb test.  They said that my card should be able to do 1920x1080 @ 24fps continuous no problem...  but I'm still getting drop frames.

He also suggested that I clear my buffer for my camera before recording.... (how do I clear my buffer..besides waiting for the orange light to stop blinking.)  (Side note KomputerBay was very quick in responding to my questions.  Thumbs up to their Tech Support!!)

Anyone got suggestions for the camera settings?

 

[ShootingStars]

I'm not sure if it'll help but have you tried frame override to 24?

[dude]

I would be interested in higher resolutions, since my 64gb 1000x kb does 1920x1080@25p continuous

[NateVolk]

Quick test before running out the door this morning.  1920x1080 @24fps continuous.

Komputer bay 128GB 1050x card.  Attached is the first benchmark, no warmups, no hacks.  Stoked on the card and the support!  I'll try higher resolutions this afternoon

Hi Nate,
Thanks for sharing your results, they look amazing!  That is how all 1050x Komputerbay cards should work. No warm up required and just start recording.

May I know what all your settings are so that I can copy your settings and see if I can get my card to work like that.

Thanks,

[alvink]

Awesome Stuff!! keep up the good work.
