The simple look and extra care that went into manufacturing the Angelbird wrk SSDs show that they are serious about breaking into the market. They have launched at a price slightly higher than average for the market but also bring the best sequential reads that Al has seen yet on a SATA drive. Legit Reviews pried the drive open to reveal the Silicon Motion SM2246EN SATA III 6Gbps SSD controller previously seen on Corsair, PNY, ADATA and Transcend SSDs, along with MLC flash and 256MB of DDR3 cache. In Legit Reviews testing of the drive they concluded that you should pick up the 256GB or 512GB model for the extra performance that it brings, you will not be disappointed.
"Angelbird might night be a household name, but the Austrian company has been around in the SSD market for a number of years and has gotten a reputation for having high quality products. When we found out that Angelbird was coming out with a new SSD product like called the SSD wrk we couldn’t wait to get our hands on one of these drives and see what Angelbird has to offer consumers. Read on to find out!"

Introduction, Specifications and Packaging
You might have never heard of Angelbird - until now, that is. Angelbird Technologies GmbH is an SSD maker based out of Vorarlberg, Austria. Their product lines have historically focused around high end and Mac-based products, with a recent arch into portable SSDs (like their SSD2go line). Angelbird is known for their high build quality, and their products are assembled using a technique I can appreciate - vapor phase soldering - (seen here) a technique that puts the least possible thermal stress on the components, as well as ensuring all solder joints are oxygen free. While the vast majority of the their prior products have been build around SandForce controllers, today they have launched a new line, the SSD wrk:
The Angelbird SSD wrk is built around a new (to them) controller, the SM2246EN from Silicon Motion:
Silicon Motion prides themselves on making SSD controllers that deliver good performance at very low power consumption. For those wanting more detail on this particular controller technology, we have a detailed analysis from last August, available at this page.

Silicon Motion has announced their SM2256 controller. We caught a glimpse of this new controller on the Flash Memory Summit show floor:
The big deal here is the fact that this controller is a complete drop-in solution that can drive multiple different types of flash, as seen below:
The SM2256 can drive all variants of TLC flash.
The controller itself looks to have decent specs, considering it is meant to drive 1xnm TLC flash. Just under 100k random 4k IOPS. Writes are understandably below the max saturation of SATA 6Gb/sec at 400MB/sec (writing to TLC is tricky!). There is also mention of Silicon Motion's NANDXtend Technology, which claims to add some extra ECC and DSP tech towards the end of increasing the ability to correct for bit errors in the flash (more likely as you venture into 8 bit per cell territory).

You may very well have never heard of Silicon Motion (SMI), a major priducer of flash memory controllers, even if you've followed the SSD industry for a while. This is primarily because the vast majority of their products have been tailored for the devices that folks tend to not crack open during review, namely USB memory sticks, eMMC devices, and SD / CF cards:
Creating controllers in those arenas will tend to force a company to do a few things very well:
- Handle a very limited number of flash channels with the greatest speed possible, due to packaging requirements for very small devices.
- Operate at the lowest power draw possible as to meet the current draw limits of the host interface.
This has resulted in SMI developing a 6Gb/sec SSD controller, dubbed the SM2246EN, using the above techniques:
The block diagram shows what appears to be a fairly standard 4-channel configuration, though there are fewer steps in the pipeline as compared to SandForce and other controllers, which should help decrease latency and improve efficiency. There is also no compression engine, which means power consumption should be further reduced.
Read on for further details on specs and power consumption, followed by the full press blast.
