I'm considering signing up for a Knownhost VPS, but I'm currently torn between the regular VPS and the SSD. Given the coupons that are available, the regular VPS would be a little cheaper, but I'm willing to pay a little more for a significant performance boost. I'm just not sure if an SSD would give a significant boost. Has anyone moved from the regular VPS to the SSD and if so, can you comment on any speed increase? I'm running Wordpress if that matters.
