This is a meh product tbh. It is 4 seperate SSDs(4 different controllers) in a RAID0 config. I'm more excited for the single SSDs that can do 700+MB/s with this interface.
I/O speed is not a bottleneck for most game servers and magnetic drives are actually a better choice for most game types, just due to their increased capacities. For the games that do benefit from SSDs (those that perform frequent writes, like Minecraft), there wouldn't be a noticeable benefit gained by using this 1700 MB/s drive versus the 500+ MB/s drives that we currently use, because IOPS is usually the key factor and both types of SSDs easily fit the bill. With no significant gain, a serious price drawback, and a form factor that makes them unusable in most configurations, and it's unlikely that we'll be able to justify including PCIe card-based drives in our dedicated machines.
In the future, SATAe should become more common and at a price point similar to existing SATA3 SSDs. They will likely be the logical next step for general server use.
John, out of curiosity, have you seen supermicros "MicroCloud" solutions, allowing 12 or 24 E3 servers in a 3U space? Have you considered using those at all? Seems like it would be a good way to save on shipping costs alone, even if the price eventually is the same as 12 or 24 1U servers.
