[Xbit] Western Digital to Release 7-Platter Sealed Hard Disk Drives

post #1 of 49
Thread Starter 
Western Digital to Release 7-Platter Sealed Hard Disk Drives This Quarter.
Source
Quote:
Western Digital Corp. said on Thursday that it is on-track to ship its helium-filled hard disk drives with enlarged capacities to select customers this quarter. The company even revealed that the first sealed hard drives will utilize seven platters. Unfortunately, as it was revealed earlier, those products will not become truly mass devices for several quarters to come.

7 platter drives, filled with helium, wondering what sort of improvements this brings. Looks like mostly enterprise applications.

You'll know your server has failed once your voice gets squeaky. I question the durability of seven platters. Somebody should make a push to bring back 5.25" HDDs so they can sell 25TB drives if we're going to be this ridiculous.

Does anybody know the reason 5.25" drives aren't the standard anymore?, was it simply that because the density of the disks increased they decided to shrink disk sizes as well.

5.25? Why not go back to 8" drives? Put 100 TB on each 30lb HDD. thumb.gif

that is actually a good idea.
most cases have like two or three 5.25 bays and only one of them is used for an odd.

I thought patter density was the key to speed and capacity. HDD's have gotten nothing but faster an cooler in the last dozen years. 800GB per platter seems not so great on a 3.5 “ drive.

Indirectly, yes. More platters also works. Apparently we're close to a wall for magnetic disks' capacity without algorithms. Right now, one bit on a platter can store a single bit of data, but efficient algorithms can store more than one bit per bit on the platter as seen by the system. If you look at benchmarks for all four capacities of WD Reds and Greens, for example, you'll see an increase in speed as the capacity goes up since more data can be stored closer to the edge. I guess it's a bit like RAID 0 in a way? It isn't the same increase, otherwise a 2TB Red would beat a 1TB Blue.
