Conclusion, Pricing, and Final Thoughts



  • Outstading sequential read performance (best we've seen on SATA 6Gb/sec)
  • High quality construction and engineering


  • Limited write speeds (further at 256GB and especially 128GB capacities)

Pricing and Availability:

Introductory MSRP's for the ARC 100 are as follows:

  • 128GB – $100 ($0.78/GB)
  • 256GB – $160 ($0.63/GB)
  • 512GB – $300 ($0.59/GB)


Angelbird SSD wrk ships with a 3-year limited warranty.

Final Thoughts:

The SSD wrk is a beautifully crafted Solid State Drive that performed admirably in our testing. Straight-line read performance from the equipped Silicon Motion 2246EN controller was the highest seen from any SATA 6Gb/s device tested to date. Random access and trace pattern testing turned in figures competitive with the best of the competition. The only issue to speak of is the limited write speeds, which put the tested 512GB model at a slight disadvantage. That write performance gap widens at 256GB and 128GB, an effect compounded by the increasing cost/GB as capacity is reduced. I would recommend the 512GB model to those looking for a high performing, aesthetically engineered SSD.

The SSD wrk 512GB gets gold for quality engineering and excellent controller choice, turning in super fast reads and good writes in an attractive package, all at a decent cost/GB.

The SSD wrk 256GB and 128GB, while untested, get silver. Why not gold? The choice of 128Gbit dies in the smaller models means reduced die count when compared to competing units which see far less falloff in write speeds, and when combined with increasing cost/GB, this double whammy makes them far less attractive.
