Fast storage for everyone
One of our more interesting visits at Computex from a geek knowledge perspective was with Seagate. Sure, the company brought along a whole bunch of solid state storage products to showcase, and while it's nice to drool over the speeds and specs, understanding how things are measured can get pretty interesting.
Seagate talked about the difficulty in coming up with a hard upper limit for SSD performance on PCI Express. Figuring it out can be pretty complex -- the generation and number of channels can give you a theoretical maximum, but in terms of a real world limit, you also have to account for how the architecture internally takes advantage of those assets.
The bottom line is, there's more to performance than what the spec sheet says. That gets even trickier when you factor in the difficulty of performing accurate benchmarks. As Seagate explains it, looking at just read and write speeds won't give you the full picture. In a real world environment, the OS could be doing things in the background that affect performance.
It's an interesting discussion and definitely worth a few minutes of your time. Check it out:
