Launched: iFlash-Dual – The iPod dual SD adapter

Proud to announce my latest product in the successful iFlash adapter range.

The iFlash-Dual, is a newly designed native SD adapter for the iPod. With the unique feature of allowing the use of 1 SD card or 2 SD cards in JBOD (Just a Bunch Of Disks) mode.

There is no switch or adjustment, the iFlash-Dual seamlessly switches from single SD mode to Dual SD mode fully automatically. Just insert a second SD card and restore/sync the iPod to see the new enlarged capacity.

As the iFlash-Dual utilises JBOD you are free to mix your cards, it has even been engineered to allow the use of different makes and models together, to provide maximum flexibility : 256Gb + 256Gb to get a 512Gb iPod, or how about 64Gb + 256Gb to achieve 320Gb, and for those on a tight budget 64Gb + 128Gb for a 192Gb iPod, and many more combinations.

With smart power management you get the best runtimes even when running two SD cards, on average there is only 20% difference in runtimes between Single card use and Dual card use. Read my runtime/power consumptions article.

iPod and SD card compatiblity is the same as the existing iFlash-Bundle.

Shipping is scheduled to start from 1st October 2015.

      @Jason – The 128GB limit is for the 6th Gen iPod’s only, and our iFlash adapters do not change that – the 4th gen/5g/5.5g/7g iPod do not have that limit.

    2. Jason

      When you say the 7th g will work do you mean the 2nd revision of the 6th gen? The iPod that came out in 09?

    Hi there, recently i bought a new iflash dual sd adapter for my ipod video 5.5 gen. i am currently using a 128GB Patriot LX Series Class 10 SDXC on my ipod . I have no problem syncing all my songs to the ipod. but after a while i notice sometimes there is no sound coming out of the headphones jack , i had to reset the ipod then the sound will come back . also while connecting to my car stereo at times the whole ipod will hang and i need to reset it again. the whole ipod will hang and i need to do a hard reset. Can anyone give me some advise? thank you .

      @Javern – Not something I have experienced, I would check it is not library size related. Is the model you are using originally 30GB? if so try removing tracks from the iPod – start with 50% of what you have now and see if issues are still present.

      hi, i am using a ipod video 80gb version. I am using Apple Lossless Audio Codec format in all my songs. I have abot 1200 songs inside my ipod. i will take your advise and tried transferring half of my songs to my ipod first. thanks

    The iFlash Dual is working perfectly so far in my iPod 5G. I’m using a Komputerbay 128GB Class 10 SDXC card from Amazon UK and have no problems yet.

    Installation was pretty straightforward, although I don’t think I seated the iFlash Dual correctly in the connector first time.

    Disappointingly the card showed a full 128GB in my Ubuntu computer, but once formatted and installed in the iPod (with no music restored yet), it only showed 118GB.

  3. Carl

    Thanks for the reply. I doubt the card has problems since it is still quite new and working properly before. I formatted it in AOMEI based from your guide before installing it into the iFlash dual but I will test it as you suggested just to be sure. I will also look into the faulty ribbon angle. Hope I can finally run this thing soon. Thanks again.

    Hi Tarkan,
    I recently purchased the iFlash dual for my 60gb Ipod Video 5.5g. I decided to use it with a single 128gb Samsung Evo+ Microsd on SD1 which is the only SD Card I have. Unfortunately, after re-assembling, the computer can’t recognize the iPod, not even a charging message appears on screen. All I can see is the message to “Restore in iTunes” which gives me a big problem since I think the computer cannot recognize the device itself. The connecting cable is quite new and was working before. Even moving to other usb ports have no effect either. Does this mean the problem is due to Samsung SD Card incompatibility or might be I possibly damaged the board opening the iPod? Thanks.

      May be you can formating your sd card and try again. You have to check before if you have moved Tarkan connector in the good side . Later ….

    2. Support

      @Carl – Formatting can sometimes cause this, also a bad or faulty HDD ribbon can cause the same issue. Try formatting the MicroSD card – while you are doing that confirm the card is fully working by running something like H2Testw against it, this will show you if the card is the capacity it says it is, and the read/write speeds.

    @Mark. Just updating my post. My 7G Dual iFlash 1TB was working after an upgrade, but not appearing on the computer. In disc mode, it said that it was ok to disconnect, but did not say anything about connecting. So put it in disk mode and connected the USB. A few seconds later the computer found it. I said I only had 137G. I formatted it anyway, disconnected and reconnected. This time iTunes found it! After an iTunes restore and after 3 hours, I have the complete 940G and 20000 songs on the iPod.

  6. Mark

    I need help please. I damaged the power connector on my 7G Dual Flash. Fortunately, I found someone that could solder it back on yo the logic board. Seems to provide all the power needed. However, now I only get the white apple and it is repeatedly resetting. I entered the manual diagnostics and every looks ok. I can enter disk mode, but the ipod does not show on the main computer. Is it supposed to do so?

  7. Dave

    @Support Thanks for your response. AH, OK I see. So I could have 128gb of memory but will only be able to hold so many tracks? So when people are installing crazy-huge capacity storage its more than likely that they are using FLAC, or similar?

    1. Support

      @Dave – The larger capacities make sense for libraries which are made up of very high bitrate or lossless files, having said that a library made up good quality high bitrate MP3’s would need around ~350GB for ~50,000 tracks.

  8. Dave

    I am super confused by all of this (to an extent). I have a 5.5 gen iPod Classic with 80gb of storage and am in need of much more storage (and no moving parts). I have looked a lot into the possibility of installing a SSD but there’s lots of info out there saying I could run into trouble if my iTunes library is too big or has too much metadata, yada yada yada…
    Anyway, hoping someone can clear things up. The compatibility chart shows no iPod being able to handle more than 128gb… so how does the iFlash Dual method work in that case, if we hope to use two high capacity SD cards together? Also is re-formatting after installation an issue?

    1. Support

      @Dave – The 6g iPods are the only ones limited to 128Gb. There are limits to the library / tracks due to the database size vs iPod memory (RAM). More info can be found here.

    I have a gen5.5 iPod 80GB that I have upgraded with the SD-Dual adapter and a single Kingston 512GB SDXC card. It all seems to be working fine but I have a query about expected battery life.

    Starting with a fully-charged battery, I have set it to play random tracks out of a playlist consisting of just under 10,000 ALAC tracks. It was running with some iPhone headphones with volume roughly at halfway up the volume scale.

    On the battery that was in the iPod when I bought it (not convinced it is an original battery and it has no markings) I got about 11 hours run time. Thinking that I should expect better than this (based on the battery life article, although admittedly that was with a 7g iPod), I bought and fitted a new battery (which claims to be 700mAh). On testing I am seeing a similar battery life/run-time.

    So, is ~11hours run time under these conditions about right for this generation of iPod, or should I expect more and have I been sold a duff battery?

    (Actually, 11 hours is probably fine for me in 99% of cases – I was just expecting more.)

    1. Support

      @Mark – The 5g/5.5g iPods use 3 times the power compared to the 7g, runtimes are much lower – Is the battery you are using the slim OEM battery (which is around 550mAh regardless of any battery seller claims), then that runtime is about right for lossless playback.

      One thing worth trying as the 5g’s can get buggy with large playlists, is do the test with a smaller playlist say around 2000 tracks.

    Does / Can the iFlash-Dual work with two 512gb microsd cards (adapter)? iTunes recognizes the Ipod classic gen 6 with 999GB but the sync process seems to freeze / crash, then the space shows up taken on iTunes.


    1. Support

      @Louis – The cards you have are fake – no such thing as 512Gb MicroSD cards. They are more than likely 4Gb/8Gb cards that have been reprogrammed to appear as 500Gb plus.

    1. Bruno

      And what about Samsung evo 850 1tb in the iFlash-SATA? Why it doesn’t work? I didn’t find 840 version for sale. I think it was discontinued.

  11. Martin

    An update on the issues I’m having with my iflash-dual (2 x 256gb cards, Ipod Classic 7th gen): ipod connects and syncs to iTunes without issue. Playing tracks via the ipod’s headphone output also works perfectly. The problems only occur when taking an output from the 30 pin connector. Plugging the ipod into the usb input on my Marantz AV receiver works perfectly (it is designed to play from an ipod and shows track details and album art on screen). Connecting to the usb input on my Sony car stereo (which works perfectly with my old Ipod video) results in random connection loss. Same thing with my Monitor Audio A100 (basically a small amplifier with usb ipod connectivity). It seems to me that it could be that 470GB is simply too much for some devices to cope with? There doesn’t appear to be an issue with the 30 pin connector itself. I might try replacing the ribbon connector between the iflash-dual and motherboard (you never know) but otherwise I’m stumped. Any suggestions?

    While the quad-micro-sd adaptor provides more flexibility and choice of media to use (which is nice), it doesn’t, with current pricing, much change the bang-for-buck ratio or the maxium possible storage size.
    Occurs to me though that a 6 or 8 micro sd adaptor, while still being about the same cost/Gb, would allow even larger storage than is currently achievable.
    just saying!

    I’m just updating my ipod 7G 2.05 with dual connector and two Patriot Lx 256 GB and …. Not OK
    there is a problem few minutes after working well . Ipod stop on track and don’t want to restart !
    There is a bug ! After itunes restauration it’s the same . Other menu work perfectly but Ipod don’t want to play music.
    So I had to reset the ipod (menu+central) and it’s ok I can listen music again , but five to ten minustes later Ipod stop again on track and don’t want to restart ! So I think the dual connector with 2 iflash 256GB Patriot Lx is not compatible.
    I checked with 1 card patriot Lx and dunble connector on ipod 5G,6G,7G and the iflash card patriot LX works perfectly.
    I will open again the Ipod and try with 2 card 256GB and 128GB .

  14. Martin

    Quick question: have just tried a Patriot 256gb sdxc card in my I flash dual (which works fine with two Sandisk 128gb micro sdxc cards). With the Patriot 256gb in one slot and one of the 128gb Sandisks in the other, I can transfer music from ITunes without difficulty, but playback is often interrupted for a few seconds before restarting again. The issue is much worse with ALAC files than with lossy (mp3) ones. The 256gb card seems to work fine in other contexts (eg playing video files on my laptop).

    Do the symptoms I’ve described suggest the Patriot card is not compatible with the I flash? If so, I’ll try one of the cards on the compatibility list.

    Many thanks


    1. Support

      @Martin – Was the same library used with the 2x Sandisk 128Gb MicroSD as that used with the Patriot 256Gb? Did you experience any of the issues using the 2x 128Gb MicroSD cards playing the same tracks?

    2. Martin

      @Support: Yes, same library, same tracks. No problems at all with the Sandisk cards. With the 256gb Patriot card in place, I’m getting long pauses when skipping between tracks and random dropouts for a couple of seconds. Playing the same track again after a dropout doesn’t result in a similar issue at the same place in the track. It seems to me that the card is struggling to keep up. The problem is much worse with lossless files than with MP3.

    3. Support

      @Martin – That is interesting, it could be the card controller is glitchy (like the older SDV Kingston cards which had similiar skipping issues), or it could be specific to the card you have.

  15. Peter

    Any comments on the quad adapter? I saw it for sale briefly and now it sold out and has gone. Was thaT a limited prototype run? It would be good to know if/when they may be back.

  16. J

    I already ordered the dual sd.

    Are the kingston sd cards still not good to use? I was looking at a 512gb sdxc by Kingston.

    What about the older lexar 600x 256gb? I see you say not recommended, but why?

    I appreciate your time
