Visualized: IBM's 1956 HDD packs 5MB of storage, requires forklift for installation

2011-12-30T11:07:00.004+08:00

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.

還在抱怨 3.5 吋的硬碟盒不方便攜帶或是雲端空間一點都不夠用嗎？這台 IBM 的 305 RAMAC（Random Access Method of Accounting and Control）想必可以完全改變你的想法。照片中這「塊」嗯... 應該說是這台 1956 年的 IBM 硬碟，內部主要是由 50 片 24 吋的磁碟所構成。這個 16 平方英尺的龐然大碟，除了每年固定耗費 US$35,000 外，而且還僅具有 5MB 的儲存空間，姑且不論當時的高科技的在現在看來有多麼渺小（一首 MP3 頂多吧？），但 RAMAC 其超過一噸的重量卻肯定讓你無法忽略它的存在。現在，讓我們開始感謝科技的進步吧！（緊握著 USB 拇指碟...）
