15-in-1 card reader vs. 29-in-1 card reader (P920)

2018-08-31, 15:09 PM

I have a P920 that I put together using the online configurator, with the 15-in-1 card reader.  This was the only MCR option for the 5.25" Flex bay that I could see.  https://psref.lenovo.com/syspool/Sys/PDF/ThinkStation/ThinkStation%20P920/ThinkStation%20P920.pdf also indicates that the 15-in-1 card reader is the only MCR option for the Flex bay.

 

However https://support.lenovo.com/by/de/solutions/acc100140 indicates support for a 29-in-1 card reader, and this post shows a card reader that appears to have more slots than my 15-in-1, including xD. (photo of my card reader attached to this post) 

 

Is the 29-in-1 card reader available in the US?  How does one obtain it rather than the 15-in-1?

 

Thanks

Solved! See the solution

Officially, the 29-in-1 card reader was never qualified on P920.  Instead we moved to the newer 15-in-1 card reader.  I believe this was done because the 15-in-1 supported some of the newer high speed card formats that the older 29-in-1 did not.

 

I think a 29-in-1 would likely function OK in P920 since it's really a standalone component that's just using a USB connection, but we've not really looked at it as far as I know.  If you chose to try this, the only way to get the 29-in-1 reader would be through FRU or Option as P920 cannot be ordered with it from the factory.

 

I'll see if I can do some digging to find out more details on the differences between the two devices.

Thanks, I would be curious to see the differences between the two devices. I had thought the 15-1 was older and the 29-1 newer but apparently I was inverted!  Good to know.

I think the major update was the 15:1 supports SD UHS-II, which is a significant improvement over the older 29:1.

 

Generally, the 15:1 is compliant to the newer storage specs for the individual formats.  So for example:

 

 

15:1

supports SD Part 1 spec v4.0 (vs v3.01 on 29:1)

supports MMC spec v4.5 (vs. v4.4 on 29:1)

supports CF spec v6.0 (vs. v5.0 on 29:1)

 

 

There are other changes as well, but this gives you the general idea.  Of course if you need one of the formats that was only supported on the 29:1 and is no longer supported on the 15:1, then the 29:1 might be the better option for you.

 

If you have questions about specific card formats, just let me know and I can try and track down the right info.

The 29-1 had a dedicated TF slot while the 15-1 seems to have merged this into the MS slot. Do you know the insertion profile for a TF card in this slot? I have not figured it out yet and have so far resorted to a microSD adapter in the SD slot, but this seems to defeat the purpose of having dedicated TF.

I think the transflash slot has merged into the SD slot (via the use of an additional micro SD-->SD converter as you mentioned.  Can't say I've ever seen any sort of TF/uSD --> MS converter.

 

That's kind of a tough call....If a dedicated TF/uSD slot is necessary, the 29:1 might be the better option for you.  But if you don't mind using the converter, then you get the benefit of the higher speed SD slot by going with the 15:1.

Hi Guys,

 

I am considering to buy a P720 or a P920. Is there an option to have a CFexpress card reader? Wondering whether the 15 in 1 Card Reader Tower has this?

 

Do you find it diffuclt to load DVDs on to a vertical dvd player? In the past I have had the horizontal version.

 

Cheers, C
