    Check out IBM's 305 RAMAC (Random Access Method of Accounting and Control) hard disk and those gripes about dragging around that USB thumb drive soon evaporate. This 1956 HDD was composed of 50 24-inch discs, stacked together and taking up 16 sq ft of real estate. The once-cutting-edge monstrosity was capable of commanding an annual fee of $35,000 and stored up to 5MB of data. Sure, by modern standards it's a pretty modest capacity, but the RAMAC still weighed in at just shy of a ton. Our technological forefathers could have done with that exoskeleton prototype.

  • Engadget Primed: SSDs and you

    Primed goes in-depth on the technobabble you hear on Engadget every day -- we dig deep into each topic's history and how it benefits our lives. You can follow the series here. Looking to suggest a piece of technology for us to break down? Drop us a line at primed *at* engadget *dawt* com. If you're a storage aficionado -- and who here isn't? -- you've probably heard a lot about SSDs, those friendly solid-state disks promising dramatically improved performance over their magnetically inclined brethren. No doubt you've heard about the advantages, thanks to NAND storage that makes them silent, shock resistant, energy efficient and lightning quick. Yet you've also heard the horror stories: drive slowdowns, controller failures and manufacturer recalls. And adding to all those anxiety-producing headlines, there's the price premium. While most magnetic drives average around a nickel or dime per gigabyte, even consumer-grade SSDs still run $1-2 per gigabyte, often for drastically smaller-capacity drives. Three years ago, Intel launched its X25-M and X18-M: the "M" stood for "mainstream," and the pair of drives were designed to reintroduce solid-state storage to a cost-conscious consumer market. (Perhaps more importantly, they were also meant to solidify Intel's standing in the nascent SSD realm, up to that point a chaotic, Wild West-style domain. But we'll get to that.) For most users magnetic drives still remain king, with solid states appealing primarily to a niche of enterprise IT professionals and modding enthusiasts. How did that happen -- and should it be different? After the break we'll look at how and why SSDs haven't (yet) conquered the storage world, and examine whether they're poised to do just that.
