Seagate Plans 37.5TB HDD Within Matter of Years
Ralph_19 writes "Wired visited Seagate's R&D labs and learned we can expect 3.5-inch 300-terabit hard drives within a matter of years. Currently Seagate is using perpendicular recording but in the next decade we can expect heat-assisted magnetic recording (HARM), which will boost storage densities to as much as 50 terabits per square inch. The technology allows a smaller number of grains to be used for each bit of data, taking advantage of high-stability magnetic compounds such as iron platinum." In the meantime, Hitachi is shipping a 1 TB HDD sometime this year. It is expected to retail for $399.
Just quickly, the specs I found for the Hitachi Drive:
- 5 discs, two heads each, rotating at 7200 RPM
- 1070Mbps transfer rate
- 8,7ms avg seek time
- 4,17ms avg latency
- around 9 watts power consumption while in "inactive-mode" (NOT reading or writing)
Hope this helps
actually they are. according to IEC 60027-2
1 kilobyte (kB) = 1000 bytes
1 kibibyte (kiB) = 1024 bytes
come on, the original specs date back from 1999.
http://en.wikipedia.org/wiki/Binary_prefix
Kilobyte = 1000 bytes
Megabyte = 1000 kilobytes
Gigabyte = 1000 megabytes
Terabyte = 1000 gigabytes
Kibibyte = 1024 bytes
Mebibyte = 1024 kibibytes
Gibibyte = 1024 mebibytes
Tebibyte = 1024 gibibytes

It's HAMR not HARM. Heat-Assisted Magnetic Recording. Here's the relevant Wikipedia article: HAMR.
FYI, 300 / 8 = 37.5
Sweet jesus, do you people not even read the summary anymore??
Endless arguments over trivial contradictions in books written by ignorant savages to explain thunder in the dark.
Who the hell modded you up? You have obviously never been involved in a large-scale backup solution.
Disks DIE. Tapes rarely do (comparatively). Tapes, although slow and linear, are incredibly durable.
HDDs aren't exactly volatile, but they are a heck of a lot more susceptible to corruption and failure due to the fact that you have both a magnetic storage medium AND the circuitry to power and control it on one device. And if one dies, you're pretty much fucked. A tape is only one of these, and is simpler and more reliable.
So why do we do things the old-fashioned way? Because it FSCKING WORKS!!
