Yes, notice how far down 40GB is on the listing. This is why I don't see the need for more than two 80GB HDDs... undoubtedly, above 1TB read and write errors cannot be precluded with such ancient technology being stretched to its limits, even with perpendicular recording technology involved, not sure if heat assisted magnetic recording will help. As for SSDs, I'm sure they are faster in some regards but not everyone needs more speed than what mechanical HDDs provide and PCBONEZ did say that RAM can be effectively used to do some of the benefits SSDs come with if you have enough of it. The problem with SSDs, though, is that data recovery is impossible... not with HDDs at least.
