    Buffalo released something recently on Realtek... Found it interesting, as the board layout for Realtek is very similar to Allwinner in the SBC space.... mostly in the SoC to RAM/NAND orientation....

    Nice to see Realtek in this space - most of the ARM's have been Marvell up to now - we've got AnnuPurna Labs (e.g. Amazon) jumping in on the high end, and Realtek on the low-end - let's see what Marvell responds with (and yes, they have a chip there that is pretty impressive).

    The eMMC is from Toshiba.

    Also, the RTD1295 would've been a much better choice, but obviously more costly.

    The SATA is running off the Realtek's USB3.0 port via the ASMedia ASM1153E, which is an odd choice for a NAS... and may explain some of the storage numbers...

    At least there is UASP, which does help out here compared to the Bulk-only Transport profile...

    Info below:

    ASM1153E is the ASMedia third generation single chip solution, bridging the USB3.0 to Serial SATA host interface with highly integrated SuperSpeed USB3.0, High Speed USDB2.0 and SATA1.5/3.0/6.0 Gbps ASMedia self -designed PHYs. Along with excellent compatibility with USB3.0 host and SATA device, ASM1153E uses advanced process technology to optimize the chip power consumption. Furthermore, it is also pit-to-pin backward compatible with existing ASM1053.

    Customers can easily enhance their storage device performance with ASM1153 since it also integrates an 8-bit micro-processor and embedded RAM to provide a cutting edge solution in USB to SATA device enclosure market.
