Bought a new hard drive yesterday.
It's for the media server PC where I store all my downloaded movies and TV shows. $150. Pretty standard stuff.

At the time, I had six hard drives in my PC (a combination of SCSI and IDE), two of which were full-height 5.25", to give me something like 500 megs of total storage. Or put another way, 0.0005 TB. It was tits. I had more .MOD files than most BBSs. (Of course, back then a megabyte was 1024 KB. We're at a point now where a few billion bytes is just a rounding error. But who's counting?) Any wagers on when the first 1 PB hard drive will show up? |
damn 150 bucks for 2 terabytes!
its amazing how much prices are coming down, and capability is coming up. |
want level: extreme.
|
Where did you buy? That's a great price!

I just got one of these in a 2TB version: Buffalo Technology - Products - LinkStation Pro Duo™
I plugged it into my router and can access it from all my computers or any pc with an internet connection. I have it set up in RAID1 configuration so I really only have 1TB of storage, but should one of the HDs go out I have a mirrored backup at all times. I can also network any printer to it or add more space using the 2 USB ports on the back. It was $289 shipped from amazon. |
Single drive PB isn't going to happen on a HDD platter. In fact even though a 2TB drive seems monstrous, HDDs are one of the slowest progressing parts of a pc technology wise. Both in capacity and speed. The future will be in something with non-moving parts.

It's not the cheapest 2TB drive out there- both Seagate and WD have 2TB units for $140. But I've been having nothing but wonderful experiences with IBM / HGST since I bought a 10 gig DeskStar many years ago, so why change?

HDDs are one of the slowest progressing parts of a pc technology wise. Both in capacity and speed. The future will be in something with non-moving parts. I agree that for laptops, we're probably in the terminal stage of magnetic storage. Lower power consumption, less heat, better shock resistance. And SSDs are starting to get big and cheap. At least in relative terms. But for desktop and server applications, I think that platters have a lot of life left in 'em. For one, there's still a staggering price gap. The $150 I spent would only get me 32-64 GB worth of SSD. That's thirty to sixty times more expensive per unit capacity, and those are the uber-cheap ones. The big-name SSDs in that price range are 16 GB. And I really don't have room in my little mini-ATX case for sixty SSDs. And a 128 GB SSD is not twice as expensive as a 64 GB device. More like 3x to 4x. They're still following the CPU pricing scheme. By comparison, a 2TB hard drive is only about 1.25x to 1.5x the cost of a 1TB drive, and on down the line. And second, there's speed. Yeah, SSDs have incredibly fast read times. But their write times are still pretty lethargic. This is an architectural problem. With any storage device, before you can do a write, you have to do an erase. No big deal with a hard drive. But SSDs require that erase cycles happen in relative large blocks, several megabytes in most cases. So if you want to write a few k of data to the device, the controller first has to read a whole block into memory, then erase the block, then re-write the block with the new data added in. As a result, the overall performance of an SSD in a typical application tends to be many times slower than a hard disk. We'll get there eventually, I'm sure. Just not soon. |
I bought that same one from newegg last week for 159 instead but with a $30 mail in rebate.
It's going into my Windows Home Server which is at 2.29tb right now. I had a media server with a bunch of drives but decided to get Home Server for some redundancy. Works great so far and I can even stream directly from it which I didn't expect with an Atom in it. |
SSD tech is changing very rapidly. Much faster than platter tech. Look into NAND stacking and more specifically Intel's recent breakthrough in phase change memory. Intel touts NAND-killer breakthrough ? The Register
Also, a block in flash memory is never as large as MB. If you into it you will find that usually a Block is 64-256KB and made up of Pages that are 512B-2KB. I have not yet seen or used a flash that can't do Page level operations. For HDD SSD's they have gotten a bad rep for a long time for their speed. The issue largely was because they were all using a siliconimage controller chip that was never designed for the application in the first place. Now the "high end" ones are using a purpose built controller and are achieving write speeds at or better than the best HDDs and read speeds that can nearly saturate the SATA bus when being read sequentially. |
I'm still hoping that the hard drive will go away. I hate them. They're the slowest part of a computer and the most unreliable. If the first PB media is a hard drive, I'm gonna be pissed. SSDs are a start. I still drool over the PCIe 1TB SSD. If it wasn't thousands of dollars, I'd buy it.

So Joe, did you mean to misspell "yesterday" or what?:giggle:

Here's a nice graphic on how media storage has evolved (via Giz):

I wouldn't expect to see PB in any consumer form for at least another 15-20 years.
HDD's are getting crazy cheap and large capacity. Picked up my 1TB external WD for $100 about 4 months ago. |

But, to paraphrase a political joke, hard drives are the worst mainstream storage technology currently available, except for all the other ones.

I think that the technology to make it happen will be available. I mean, consumer-grade hard drives went from 100 megs to 1 gig in about 5 years, from 1 gig to 100 gig in another 5, and from 100 gig to 1 TB (ter?) in roughly 6. And all the while, they've gotten smaller and contained fewer platters. The actual increase in storage density (bytes / cm2) has grown much faster than that. OTOH, I'm not sure if there will be a demand for it. We're now at the point where I can store more HD video on a drive than I can watch in several months. Perhaps if a technology (by which I mean more of a legal and contractual evolution than hardware) comes along which makes the concept of going to the store and buying (or renting) a physical thing with a movie on it totally obsolete, then it'll become necessary to have PB-level storage. Microsoft and Netflix are making good strides in that direction, but critical mass is still a way off. |
:fawk:
So that was you? |
I think demand not technology will be the reason for the slow down. I just can't see consumer users needing 1PB or more within 15 years. With high def video he need for more storage increased pretty rapidly, but I don't see audio or any other formats getting much more dense in that time frame. Can you even imagine needing 1000TB for your home computer? I feel like I have a pretty damn large need of space and I can't even manage to fill my 1TB external storage drive. Like I said, I don't see audio getting much more dense, nor for image formats, maybe video will take another few leaps in that time, but surely not on that scale.
I also don't see any current storage technology capable of it. I know it will be along one day in the near future. Either way, I give it at least 15 years, if not quite a bit more before you start seeing 1PB-2PB drives like you are currently seeing TB. Then again, I also think the next 15 years will be very interesting times for technology. Computers may not even exist like they do today. |
Is the "Deskstar" still considered the "Deathstar" in terms of reliability?

The fact of the matter is that as storage, both ram and hdd, increases in size the programs that run on them will be created larger and larger in size to provide more functionality. |
