There are some interesting discussions revolving around Robin Harris’s StorageMojo blog—too bad he’s taken a vacation just when the discussion’s getting really good. The topic is SSD architectures and whether disk-form-factor SSD arrays can possibly provide the kind of performance speed-hungry applications require.
At Kaminario we’ve long argued that a disk-form-factor SSD architecture is inherently flawed. While the SSD itself might deliver on performance, inevitably the legacy storage controllers and other legacy components become a performance and reliability bottleneck, increasing latency and reducing throughput as several SSD’s vie for the same limited pipe.
