This article says that the Syba SD-PEX20122 card has ASM1042 controller hardware, yet Syba's site and everywhere else says that this card is based on 'VLI VL80x USB 3.0 Host Controller IC'. I imagine USB might just become a smaller part unless the reengineer the protocols and encoding but that might also kill any backwards compatibility it has currently. So while USB 3.0 is great for where I work and such, as a lot of customers may not be able to afford eSATA or TB devices or have those on their PC, its not going to be able to keep up with demands of people who use multiple large eHDDs for data storage and thats where eSATA 6Gbps and TB will come into play. I imagine if the drive had a better controller (say current Sandforce) it could reach 500MB/s (SATA 6Gbps speeds easily since the interface was designed with this in mind. As well, it reaches almost 300MB/s read and write which is just as fast as a SATA 3Gbps SSD goes. A 4GB file will have a better average transfer rate than a 4MB file on USB, eSATA or TB.

While its a Mac based drive you can clearly see that as the size goes up (4KB->1024KB), the speed goes up which makes sense. And while its nice to have a faster USB standard like USB 3.0, the main idea behind USB, a single connector for peripherals like mice, KB and printer, was designed when eHDDs were almost non existent.įirewire was designed more with eHDDs and the such in mind and had better encoding and protocols in place to support eHDDs and such.Įven better is Thunderbolt which has shown the ability to reach top end speeds of the attached device: One thing with USB is that it was never designed for massive large data thoroghputs like eHDDs and larger flash drives.
