Hard Drives Down To A Dollar A Gigabyte
Junky191 writes "I doubt anyone else noticed this- but today is the first day where mass storage is available for $1 per gigabyte (according to pricewatch,). There are several stores now selling 120GB models for $120 shipped. This is truly an amazing milestone for those of us who once spent $500 for the fantastically large 10MB models. I just can't wait for the days when things are $1/TB." With discounts, the price has been that low for a little while.
1957, the first hard drive was introduced as a component of IBM's RAMAC 350. It required 50 24-inch disks to store five megabytes (million bytes, abbreviated MB) of data and cost roughly $35,000 a year to lease - or $7,000 per megabyte per year. For years, hard disk drives were confined to mainframe and minicomputer installations. Vast "disk farms" of giant 14- and 8-inch drives costing tens of thousands of dollars each whirred away in the air conditioned isolation of corporate data centers.
Bought an Atari SH204 20meg hard drive for my beloved 520ST, $985.
Inside was the circuitry to make the atari interface speak MFM/RLL, and a full height 5.25" Rodime 20meg hard drive. 65ms seek time.
If I've done my math right, that's $50,432 per gig.
Wow, this is amazing if you've been around for a while.
My first hard drive was 105MB (that's mega, not giga) and cost $600. Of course, that included the SCSI interface for the Atari ST I was hooking it to.
The big question is where the lower-capacity drives are going. It seems like a decent drive always costs about $100 - and the amount you get for your $100 keeps increasing - but where are all of the 40GB drives that should be floating around for $40 apiece?
It's Slashdot's evil twin... SlashNOT
Well yes, the prices have dropped immensly indeed - however it might be worth considering that the basic concept of physical storage has not changed a bit. We are able to squeeze more bits into each square millimeter, but access speed has maybe changed by a factor of 50 or so (I'm guessing here, so please correct me). At the same time, processor speeds have aptly doubled in speed every 18 months or so.
I do appreciate cheap mass storage on my desktop, don't get me wrong, but I really long for things like static memory or holographic storage devices. And the use of spinning copper disks is not exactly power efficient either - so on the laptop front, new storage technologies could make a big difference.
The first hard drive I bought cost me $500.
It was a 10 MByte (yes, that's mega) Seagate. Full height 5 1/4 (hint, a CD drive is half height).
I partitioned it into 4 drives:
C: 1M - DOS (V 2.0 !)
D: 4M - Applications
E: 4M - Data
F: 1M - Testing
Mind you after struggling with two 5 1/4 floppy drives, this was heaven.
I still have it, after all, where could I possibly sell it?

Retail stores are a very good place for HD's. You will often find BestBuy/CompUSA/Staples/CircuitCity/OfficeMax etc will have lower prices on HD's then what is at pricewatch, local computer stores, and even regional computer expos. More then likely you get a retail drive in a box with full warranty (mainly 1 year now) and maybe even a UDMA cable and 5.25 adapters. Most mail ordered I've seen are OEM and 30 days at best. CDRW's are the same way.
Sometimes you may have to deal with a rebate to get the good deal but at least one of the above retailers has one good deal a week. Not sure if SalesCircular covers all areas of the US but it is a good place to scope out retailers sale prices for a week.

I have no idea why anyone would ever need a TB drive at home...but if it comes down to betting, I'll bet with history, and bet they will.
Would you pay twice as much for the same capacity? If so, then get two, big, cheap drives, and use mirroring RAID. You get much faster data rates, and you have backups.
Best of both worlds...

That's something I've learned about PC hardware. You must plan for failure. That's what RAID and backups are for. I've been buying harddrives for $1/GB for over a year now. I buy the cheapest drives I can find, 80GB Seagates, and use a few 100-200GB drives to build a RAID. The Seagates work well in swapable drive bays and have been very stable. I had one problem and it was only a missing pin, no data loss or corruption. But then again none of the data I store of them is important by itself.
The best technology today IMO is a few cheap 1394 controllers, some 1394->IDE converters and the cheapest $/GB drives you can find. Build a RAID, probably in a custom case with like 8 or 12 5.25" drive bays, use swapable IDE enclosures and have the box email you when the logs show a drive is about to fail. It might cost a little initially but it is mostly fault tolerant and dirt cheap in the long run.
if you could pick up a 40GB drive for $40, or a 20GB for $20, without having to fool with rebates. As it is, the cost of hard drives seems to be staying at around $100, almost regardless of capacity, limiting you in just how cheap a system you can build. Right now the most expensive item in a bottom feeder system is the HD. On Newegg you can build a minimal Duron system for:
20GB HD: $69
All-in-one mobo: $51
CPU: $31
Case: $28
128MB SDRAM: $22
CD-ROM: $19
Floppy: $8
Total: $228
If that 20GB drive were $20 instead, that would be only $179. Of course, there are reasons why the drive isn't $20, I'm just lamenting.
In this paper, dates were predicted for a megabyte per buck, a gigabyte per buck, and a terabyte per buck. I recall that this 1980 paper predicted a gigabyte per buck in 1999; pretty close!

By the way, Post named in this article the "Shannon" = 1 mole of bits = 6.02 x 10^23 bits.
Now THAT's a big memory!
