Title says it all really. What is the fastest memory, and is an HDD faster than a flash drive? This is purely out of curiosity.

a lot probably depends on the hard drive and the memory your using. For example, most flash drives today are definetly faster then an IDE hard drive (133 mb/s vs 480) however, Sata starts out at 1.5 gb/s which is definetly faster then a flash drive with sata II at 3 gb/s and so on and so forth, and that SSD drives are far faster then a typical hard drive. Keep in mind however, that with most flash drives their bottleneck isnt the memory itself but the interface, they use USB which is only like 480 mb/s transfer rate or something like that. . .while with a typical hard drive its the spin rate and read rate thats the bottleneck. . . both have their purposes. As for who makes the best? I dont know, lol when I need a new flash drive I usually just go down to wally world and buy a new one of whatevers the cheapest, have never had one fail on me and they all work great. My favorite is probably a 2 gb Patriot flash drive that came with my Patriot Viper memory, it seems to run a hair faster then most and holds a bit more then most 2 gig flash drives, but in the end, I just like the looks. It looks cool. :D

What the specs say about transfer rates and what happens in the real world aren't always the same thing. Example, a SATAII hdd which has a transfer rate of 3Gb/s will average around 25 Mb/s when it is used in an external case connected to a USB2 port which has a transfer rate of 480Mb/s. :thumbsup:

Like I said, its usually not the hard drive that causes the bottleneck its other factors-in an internal case-with a regular 7200 RPM hard drive, its the hard drive, not the SATA that will bottleneck it. Not so if you have a RAID 0 setup or SSD drives. . .

These are about as fast as you can get. I am seriously considering one when I rebuild my Office PC. For now I am on my laptop most of the time.
