Turn 10 micro SD cards into a SATA SSD drive


This adapter from looks like an interesting solution to replace or create more storage for a computer that uses 2.5 inch SATA hard drives. It’s a micro SD to SATA 22-pin converter card card that has been designed to use up to 10 micro SD cards. Once installed, it appears as an ordinary SATA hard drive to DOS, Windows 3.1, NT4, 98SE, Me, 2000, XP, Vista, Mac, and Linux operating systems and can be configured as a bootable drive. Note that you will need to use 1, 2, 4, 8 or 10 micro SD cards at one time as it will not support an odd number of cards like 3, 5, 7 or 9 micro SD cards. Also, when you use different capacity micro SD cards in RAID mode, the total capacity of the drive will be the smaller capacity of micro SD card multiplied by the number of micro SD cards. The adapter is priced at $24.99 from Amazon.

    I can only see support for Raid 0 on the site. That means Striping only. No data redundancy. A failure on any of the micro cards will cause loss of data across entire card. Keep this in mind if you are going to rely on it for critical documents. The upside is with 10 cards, the potential speed can be quite high. This is often a nice trade off, if you want extreme speed and a failure of drive will not hurt you. This could be scratch drive for video editing, install games on it for fast load times (keep your saved games backed up).

    But then again, you arn’t going to find a good quality RAID 1/5/6/10 card for $35

      This is (for my part) what i think after what i see (i did not buy one).

      I think if one microSD fails some data will get lost, but not all, from what i can see and think, the Raid 0 is not a 10x Raid 0.

      Seeing a little deep i see there are “pairs” Low & High.

      So i can asume it will do five Raid 0 sets, and over that a BIG Raid (concatenate).

      If it realy could do N x Raid 0, what is the reason for multiple of two? raid 0 can be done with 2, 3, 4, 5 , etc.

      I think it is really doing a full disk composed of: Raid 0 (0 & 1) – Raid 0 (2 & 3) – Raid 0 (4 & 5) – Raid 0 (6 & 7) – Raid 0 (8 & 9).

      That is the main reason i do not buy it… i am looking for a real 10 x Raid 0, so with class 10 microSD a speed of 100MiB/s minimum.

      If i am rigth this card will do a no much more than 20MiB/s (using on all slots a class 10 microSD card).

        You obviously have absolutely zero clue how an RAID0 would function.

        10 drives doing 10x RAID0, would be 10 logical drives for the windows, the same as individual drives.

        RAID0 across 10 drives would be single logical drive to the OS & FS, and loss of a single drive (MicroSD here) would mean total loss of data.

    I might get one to do something with this draw full of 8gb cards.

    Memory cell technology used to create SD cards does not have the durability to make critical use of something like this.

    Even if you give a conservative life of a year for an SD card being written to continuously before a failure you have 10 cards and their individual MTBF so it’s kind of a crapshoot.

    I agree with Andrew that this is probably only good for a scratch drive or some sort of cache which could be a pretty advantage. I wouldn’t use it for anything important.

    If you’re willing to install this kind of converter, search ebay and find similar ones. 21~23 bucks.

    Quite useless, in my opinion. Even if you disregard the fact that a real SSD has lots of data-safety stuff going on, which an SD card does not, even then this is not worth the money.
    Let’s assume you want to create a 256 GB drive. You’d need 4 SD cards of 64 GB, which cost around $20, so that makes $80. Add the $32 for the adapter, and the total adds up to $112. A real 256 GB SSD will cost you about $100-110. And that SSD is a lot faster and safer.

      I imagine this would likely be for people who already have a stack of card lying around. This gives the cards a new lease of life. I must have 30 or so SD cards lying around of all different sizes but most commonly 8GB ones so I could get a 80GB drive going on here for $30 odd bucks. Not too bad at all!

      Well, if you can tweak it, you could turn the thing into a RAID 1 + 0, in which you have both striping and mirroring.

      • chris martin December 23, 2016, 12:16 am

        well i was thinking as long as the board took care of the raid 0 you you could get 2 the ‘sata’ cards and maybe raid 1 in bios.

        • Pierre June 29, 2017, 7:24 pm

          I tried to connect 2 in the same box, and the BIOS will only see one. This does not appear to scale well at all.

    • DC Guy November 1, 2017, 9:24 am

      That setup makes no sense when you can have 10.

      Using your pricing, 10x 64GB = 640GB at 232$, still not a good deal but cheaper than most actual SSDs.

  • Alex August 10, 2016, 7:39 pm

    Where can someone buy this???

  • chris martin December 23, 2016, 12:23 am

    anyone know what them maximum size is for a mic sd on this? 32? 64? 128gb?
    think i want to give it a go for the lolz

    • Craig January 29, 2017, 11:18 pm

      Currently 128g/card, and I kinda want one.

      • chris martin February 24, 2017, 9:45 am

        ive tried 2 of the cards cant get ether working with 10x 64gb and 1 x 32gb on its own. tried via usb caddy and sata on mobo. im £300 in whole unless i can get working.
