Specifications & Features
The sample that OCZ submitted is a 240GB version of the drive. This series is equipped with Toshiba MLC NAND, flash memory from the A19nm node. The NAND flash used is labeled: TH58TEG70DKA4C.
OCZ will release three models within the ARC 100 range, 120 GB, 240 GB and a 480 GB version. Due to the architecture and memory channels used, the 120 GB edition will be a notch slower. This is pretty much the thumb of rule for any brand BTW. Still a 120 GB SSD performing at 475 MB/sec read and 395 MB/sec write performance remains very fast, especially if you keep the price in mind as starting at 240GB you are seeing 50 cents (USD) per GB, say 40 to 45 cents per GB in EURO.

The OCZ Barefoot 3 M10 controller
The flash memory is tied towards the Indilinx (owned by OCZ Technology) Barefoot 3 controller located under product code Barefoot 3 M10. This is an 8-channel NAND flash controller and the third revision from Indilinx, it comes with an all too familiar dual-core ARM architecture. The Barefoot 3 controller makes used of a pretty big memory partition for caching, that means that internal DDR3 memory plastered and hammered shut onto the PCB being used as file and data cache. The SSD has 512 MB of cache divided over two 256 MB ICs from Micron, but as we'll show you later on in the photo shoot, there is room for more. On the next pages we'll be showing you some PCB photo's as well, and what you'll notice is that it carries DDR memory caches as well. In-between the different SKUs the 240 GB has a 512 MB buffer, and some write speed variation with the lower capacity model. Over the SATA3 / SATA 6 Gb/s interface you may expect read speeds up to 490 MB/s and writes up to 450 MB/s based on volume size of the SSD. All the ARC 100 models have an advertised 4K random IOPS rating in-between 75,000 random read and 80,000 random write (4K aligned).
