Exactly, sequential write is what OCZ advertises. This review focuses on random write, which all SSDs are poor at, due to the fact that flash has to be rewritten in large blocks. So for example, writing 2KiB of data requires deleting a 2MiB block and rewriting the entire thing with the old and new data; it isn't as simple as just sticking the 2KiB of data in there. This situation reduces the effective file transfer by 1000 times (i.e. writing 2KiB of data effectively requires writing 2000KiB of data), so it's easy to see why writing a bunch of small files really slows things down. Despite the poor random write performance, SSDs still usually outperform spinning disks because they are far superior in about every other metric. Or at least that's the case with SLC, MLC has higher access times which hurts random read and write.
And one solution (that will hopefully be adopted soon) people mentioned earlier is the use of a write buffer. For example, you could use a high-speed DRAM chip to store write operations until you have 2MiB of data that can be sequentially written to the SSD. Not only can this increase write performance, but it can also significantly increase the life of the flash memory.
