An SSD is implemented a little like a RAID array internally. Higher capacity SSDs have more flash chips and tend to be faster. So one would expect that 2 x 128GB drives in RAID 0 to perform similarly to a single 256GB drive.

Wouldn't being able to offload to multiple SSD controllers potentially help too if that's the bottleneck?

  It would - you'd have the aggregate bandwidth of the multiple controllers to use. Similarly, RAID-1 is better for random reads than RAID-0.
