March 8, 201115 yr here is a link from engadget showing samsung squeezing 1TB per platter resulting in 4TB 3.5" drives. The 3TB drives have yet to be fully implemented into consumer technology yet and they are already being pushed aside. It is an exciting time to be a digital storage guru. http://www.engadget.com/2011/03/08/samsung-hdd-manages-1tb-per-platter-areal-density-enthusiasts-r/#comments

March 8, 201115 yr I'll start getting excited when I can use 4TB drives in unRAID! Maybe after the 3TB are considered reliable. LOL
March 8, 201115 yr It is an exciting time to be a digital storage guru. It is always an exciting time. I have worked with memory chips from 1 kilobit (only 128 bytes!!!) up to today's gigabit devices. I have worked with hard disks were a 3 megabyte drive with a removable disk pack was the size of a washing machine up to today's multi-terrabyte drives. Whatever comes next is always more for less in a smaller space and is always fun.
March 8, 201115 yr I here that when I was in the Navy in the 90's we had Magnetic Disk Packs in our system. 200MB and the drives where driven with Hydraulics. Every 6months or so I had to rebuild them and the process took easily 14hours for each system. We had two of them. I'm sure they have since been replaced, but man I hated them. They reminded me of a stack of Albums made out of metal and I'd sware they weighed at least 15LBS.
March 11, 201115 yr The first hard disk drives I worked with were DEC RK05 - a whole 2.5MB on a 14" disk! Still, when you only had 32kB of main memory, there was little need for huge storage devices! We then moved on to the RK06 drives, with a tremendous 14MB.

They reminded me of a stack of Albums made out of metal and I'd sware they weighed at least 15LBS. I started out with big disk packs like those. Sounded like a turbine when they were spinning up. Head crashes had a smell you didn't forget. The platters were exposed (the plastic cover just comes off like a cake platter) and several times per year they were placed in a washing machine what washed and spun them dry.
March 11, 201115 yr The first hard drive that I worked on used these platters. http://www.grandideastudio.com/portfolio/hard-drive-coffee-table The platters were mounted vertically on a horizontal spindle. A byte was written in parallel, one bit on each platter surface. There was a story that during maintenance, with the cabinet opened and the drive running, that the spindle broke loose from its mounting. Rolled across the floor and almost killed someone.
March 12, 201115 yr Two most memorable PC era drives. Seagate ST-225 - 20 Meg 1/2 height My first drive (although I used a Tecmar 5MB drive at work), installed in my Compaq luggable. This was in the DOS 1.1 days. No subdirectories. "del *.*" had a whole different meaning back then. http://a.imageshack.us/img828/2729/hddi.jpg[/img] Segate ST-4096 - 80 Meg full height Not my first, but my most memorable hard disk of all time. This full height baby would pass the drive over test and live to tell about it. It was a tank! And 80MEG on a single disk. Unbelievably large in ~1991. Weighed in at ~6.5 lbs.

"del *.*" had a whole different meaning back then. I still have one of these in an external SCSI enclosure in a box with a Macintosh Plus, 4M RAM, and overclocked from 8 to 16Mhz.
March 12, 201115 yr I would like to see existing (working in unraid) 2TB drives manufactured with 2 1TB platters. Less power and quieter.
March 12, 201115 yr FYI - Samsung reps have said the drive that was "shown" was not a 4TB drive and they do not currently have a 4TB drive. If you look at the part/model number on the drive shown, it is also missing a "4" in there, which would indicate 4TB. http://www.xbitlabs.com/news/storage/display/20110309153832_Samsung_Denies_Demonstration_of_4TB_Hard_Drive.html But, with the new 1TB platters, I am sure it won't be long...
March 13, 201115 yr If you can fit 5 platters in the existing 3.5 inch HDD format then 5TB drive should be possible using exising technology. Peter
March 17, 201115 yr If you can fit 5 platters in the existing 3.5 inch HDD format then 5TB drive should be possible using exising technology. Peter Hitachi uses five platter designs in some of their drives. Most manufactures don't go over four platters. Sent from my HTC Incredible using Tapatalk
