Ball Bearings versus Liquid Bearings (Score:5, Insightful)
Would someone care to educate the Slashdot masses about the differences between the old bearings and these new liquid ones? I'm in the market for a new drive, and I'd be curious to know what the difference is.
Well, I can't speak for hard disk drives, but I can maybe draw an analogy.
Wheel bearings - on cars, trucks, bicycles, whatever - use ball bearings. They're a set of caged balls, and one surface literally rolls over the other on a cushion of tiny little balls or cylindrical rollers. Here's an animated GIF and some other neat stuff. [howstuffworks.com] The problem is that, whatever the lubrication, eventually the balls and their races will wear, which increases the clearance between the two surfaces and causes looseness ("play") within the bearings. In wheel bearings, this translates into a shimmy in the wheel and weird tire wear. In a hard disk drive, this would result in a shimmy to the platters, causing less precision in data reading and writing as the platters vibrate nanometers back and forth under the heads. As the drives get to higher and higher capacities with the same physical disk size, the tracks being used must be getting smaller, and therefore this error becomes more crucial. Also, notice that hard drives which have been running for a long time tend to get noisy... Never mind that bits of metal being worn out of bearings have to be contained somehow so that the platters and heads don't get damaged.
Liquid bearings are used in all modern car engines. Oil is pumped from the oil pan into a very tiny space between a relatively soft bearing shell and a very smooth and hard crankshaft or camshaft journal. As the shaft spins, the oil is distributed thoughout the bearing surface and eventually leaks out the sides where it drains back to the pan to be pumped through the system again. Here's a picture of the main bearings of a Ford V8. You can see the little holes where oil is pumped into them. [fast351.com] While the engine is running, theoretically, the shaft's journal and the bearing surface never actually touch each other; they ride on a cushion of continually replaced microscopic ball bearings (oil molecules). During circulation, the oil takes the heat away from the bearings, and washes away impurities.
How you'd implement something like this in a hard disk drive, I have no idea, and I'd love to see any real techical info on it. (Marketing hype will not answer the questions I have.) But it's a great idea; in a server, with the hard disks spinning all the time, the hydrodynamics of the situation suggest that the platter bearings would never wear, and would therefore never have their tolerances open up and incur vibration.
But a seal would be required to keep the lubricant off the platters, and that seal would itself eventually wear out. Not to mention that it's unlikely they'll include a provision to do an oil change on these things. Stopping and starting cycles will wear the bearing and journal material, causing tiny abrasive bits to be floating in the oil.
I like the idea, I think it's a great step, and I'll look forward to seeing how hard disk manufacturers have solved the problems.
Would the new bearings come at a price premium?For sure! Even if it costs less to machine these than the super-tight clearance ball-bearings that modern hard disks must use, they'll still be a "new feature" which can enhance prices and profit margins. But I think they will actually cost more to make; it's just that ball bearings (like older stepper motor head actuators) have too many limitations to work with modern capacity and track density demands.

Some short answers are:
b) Worn ball bearings seriously disturbs the servo system from keeping the read head or the write head on true center of data track. This puts a ceiling on increasing track densities.
c) Very strong error correcting codes are applied to every data block (about 512 bytes) and not on any unused surface.
d) As for unused surfaces, there are multiple issues in this decision, but a new feature from some manufacturers is to reserve one outside surface for a template servo pattern & BIOS code so that the drive can self write its own servo patterning and more cheaply load its BIOS code. This reduces / obviates the many hours it takes of very expensive capital equipment to write servo patterns to drives.
e) Spin speeds above 10K introduce horrendous resonances at the outside of platters that make servoing tracks much harder. One remedy has been to reduce platter diameter & capacity (by about 10% as I recall).
And the long version of a) & b) or 101 of disk drive servoing:
For atleast a decade, hard drives have used embedded servo patterns on every surface that are intermingled with the data areas. Using a dedicated surface for servo worked long ago only because track & data bit densities were much lower. Todays drives typically have 120 or more curved radial servo wedges that costs 5-7% of the surface area. User data tracks nestle between these servo wedges.
1) In these short servo wedge areas, servo tracks contain a few tiny fields of digital servo data followed by several analog modulations so that the servo processor can sense its fractional position within any servo track. Servo tracks actually abutt each other and the only bit change between adjacent servo tracks is in the Gray coded track no. Since IBM patented this many years ago (1980's ?), manufacturers have since added proprietry extra small digital fields to correct for read errors in the digital fields & analog modulations to continuously improve servo tracking and hense improve data track densities.
2) The user data tracks are not neccessarily pitched to be inlign with servo tracks and may be reduced to 2/3 the density of servo tracks. This provides guard space and reduces inter track symbol interference. As the disk spins from servo wedge area on into user data area, it becomes an increasing act of faith that the read head or the write head is indeed still following a track center until we reach the next servo wedge. Such miss tracking is called runout.
A major source for Non-Repeatable Runout comes from worn bearings which introduces random wobbling, and this degrades the servoing and limits tracks densities.
Fluid bearings improve upon ball bearings because they don't introduce this NRR so spinning is quiter but more importantly track densities can keep climbing.
There are quite a few other NRR & RR terms impacting on servo tracking.

Now, when comparing performance to a real live IDE RAID controller (Adaptec AAA or 3Ware, etc.), it is not as fast. These controllers have an on chip implementation of RAID 5 (ie hardware XOR etc. usually implemented on an intel i960 or somesuch) and perhaps some cache memory, and they interface with the OS using the standard SCSI drive api.
Now software raid 0 or raid 1 is often just as fast as hardware raid 0 or 1 because the implementation is so simple and the drive r/w speeds are the limiting factor.

There are four 8-bit registers, and the "head" register uses 1 bit for master/slave selection, one bit to select CHS/LBA addressing, and two bits are "reserved" (originally used to select sector sizes, but in modern times sectors are always 512 bytes).
ATA-6 kludges this 28 bit LBA limit to 48 bits by specifying that the host is to write 20 bits twice!
But for the forseeable future, 32 bit computers will only really use 32 of those 48 bits, which turns out to be only 2 terabytes. If the operating system uses a signed integer (common practice, including the linux kernel until only recently), you only end up with 31 bits of sector addressing, or just one terabyte.
Of course, there are probably even more limits lurking. Doesn't linux ext2/ext3 use 32 bit numbers? FAT32 uses 28 bits for cluster numbers, but clusters can be as much as 32k in the standard (apparantly larger in some systems, though Microsoft doesn't document that in the FAT32 specification).

Does anyone know if fluid dynamic bearings would change the minimum temperature that a drive requires to spin up?
Well, assuming that these fluid bearings are smooth races with a "ball bearing" of oil molecules in between (ie. like bearings in any car engine since the 1930s), absolutely.
From the descriptions, from what I can tell, we're only talking about bringing automotive engine main bearing technology, on some scale, to hard disk drives.
Whatever the liquid lubricant, when it's cold, it's likely to be thicker. Which will mean that it will take more motor torque to get it spinning when it's cold. (Think of how much slower your starter motor turns your engine on a really cold day; not all of that is the reduced efficiency of the battery in cold weather!)
I think, in cold environments, these drives might take a while longer to spin up, but once they're spinning, the turbulence in the oil in the bearings will warm it up quickly enough. Also, when it's really cold, the bearing clearances will be smaller because they probably will have contracted more than the journals.
Compared to ball bearings which will have no fluid filling the bearing clearances as the temperature changes, I'd imagine these will be less prone to vibration and read/write errors as the bearing temperature changes. (Not that it matters much, all modern hard disk drives use a closed-loop servo system to detect the position of the heads relative to the platters.)
