The first SATA 3.0 motherboard isn’t even on the market yet, and the standard has already been exceeded. A-DATA presented "XPG EX93 2.5" to 3.5" SSD Converter", a product that enables you to use 2.5" SSD in a desktop case. However, the part in hand is not just a piece of rubber.
The adapter fits nicely in a single 3.5" bay and packs a RAID0 controller – you know where this is heading, right?
The regular desktop case usually have room for either three or four 3.5" drives…
According to the manufacturer, the RAID controller is capable of handling read speeds of up to 825 MB/s, and massive 1.115 MB/s write transfer rates. By pairing two 500GB SSDs together, the EX93 2.5" to 3.5" Converter will give you 1TB of storage capacity and a top write speed of 1.1GB/s, which is simply breath taking.
If it was true, of course. Even A-DATA was very confused, with PR representatives giving different numbers than sales than the ones that were printed on the spec sheet.
The spec sheet states the adapter itself is limited to SATA-I/II interface and can give out 230MB/s read and 170MB/s write speeds. A-DATA PR claims that it can reach 825MB/s in read and 1.1 GB/s in write transfer rates, while math dictates that if you pair two of the fastest SSD drives A-DATA makes, you cannot have more than 460MB/s in read and 320MB/s in write mode. Yet, the company released a screenshot of CrystalDiskMark showing more than double of those figures and an appropriate press release.
The answer to that dilemma is simple – A-DATA connected couple of drives to the motherboard and that was that – I/O on the motherboard was completely maxed out. This is what you can expect from a single cable.
Since the converter outputs only a single cable out, you can connect up multiple SSDs in a standard cage in a double RAID0 configuration and well, have storage speeds exceeding those of the PCI Express bus. It is really impressive to see where engineering ingenuity is heading. The storage market was "dead" for so many years and now we have to admit that it feels just awesome to experience all the new innovations coming in that field.
