Let the hive mind of Engadget get that for you.
"I'm looking for a solid state drive, around 32 to 64GB, for use in my web server. The drive will contain my web sites and the operating system, either Windows Server 2008 R2 or Ubuntu. Large storage is handled by a separate RAID array, so capacity is not an issue. Rather, I am looking for the fastest, longest-lasting, and most reliable drive under $150 that is suitable to my application. Any thoughts? Thanks!"
I don't think this dude is claiming he can't see the difference between HD and SD (that's just stupidity or plain old blindness), I think he's just saying how fun it would be to mess with someone's head like that.
Now, if he really is claiming that he can't see the difference, perhaps he needs to have his head examined or at least get his eyes checked. But then again, he looks pretty old so maybe he can't tell the difference. My Gpa can't really tell the difference, but he's 75, or perhaps he just doesn't care, which is more likely.
