- xcheats, on 10/12/2007, -4/+36Why the hell do you need a 10000 RPM HD in your iPod?
- gcnaddict, on 10/12/2007, -1/+18"Plus how noisy and unreliable would that drive be?"
Noisy? I'll give you that.
Unreliable? You're on some serious crack. This is an enterprise storage drive. - astralway, on 10/12/2007, -0/+15Technophiles are "enamored" with harddrive progress since it is a principle bottleneck within a modern computer. For many applications, particularly for multitasking, you will spend more time waiting while your HD thrashes rather than actual processing time. IO is a significant issue that should not be overlooked.
- inactive, on 10/12/2007, -4/+16well played. +1
- tomerak, on 10/12/2007, -4/+12The iPod HDD is a 1.8" disk drive not the 2.5" and I think 15Krpm or even 10Krpm would significantly reduce the battery life. although I do agree that a 150GB iPod would be very cool!!
- dark1587, on 10/12/2007, -0/+7These drives are used in IBM Blades and 1U servers where you need to consolidate space as much as you can. And to see a 15k 2.5" drive is nothing but good news for companies who want to utilize smaller servers without sacrificing disk performance.
- Zreitan, on 10/12/2007, -2/+7That's..umm..fast..
- vuke69, on 10/12/2007, -1/+6Pssst... flash is painfully slow.
- Urusai, on 10/12/2007, -1/+5I know notebooks use 2.5" IDE, but these are SCSI. Who uses them? That fast on a notebook would seem to invite gyroscopic effect problems.
- ez12a, on 10/12/2007, -0/+4"Ummm SAS? This is not a notebook drive people."
"Serial Attached SCSI (SAS) is a computer bus technology primarily designed for transfer of data to and from devices like hard disk, cd-rom and so on. SAS is a serial communication protocol for direct attached storage (DAS) devices. It is designed for the corporate and enterprise market as a replacement for parallel SCSI, allowing for much higher speed data transfers than previously available, and is backwards-compatible with SATA."

Theoretically, the 2.5" form factor allows it to be a laptop hard drive. Did you not know that modern laptops use SATA drives?
"Why the hell do you need a 10000 RPM HD in your iPod?"
I'm pretty sure they don't use laptop 2.5" drives in ipods... - kob0724, on 10/12/2007, -0/+3Doesn't flash memory still have that nasty little problem of only being able to be written over a fixed amount of times?
- SaumZ, on 10/12/2007, -2/+5Companies should be focusing more on flash storage and making that "bigger" and "better". This is where the future of storage will be, it's more energy efficient, there are no moving parts, and they are a lot easier to backup and restore.
- merreborn, on 10/12/2007, -0/+3The drive in the ipod really doesn't need to be any faster than 5000 rpm. There's simply no benefit -- 5000 RPM is more than fast enough to stream video data at any bitrate. Anything higher would run hotter, draw higher wattage, be more expensive, and be more prone to fail when you drop the thing.
Same goes for just about *any* embedded device, like Tivo. If you stick anything faster than 5000 RPM in your Tivo, you're not gonna see any performance benefit, but your Tivo *will* run hot.
You could stick this thing in a laptop... But you'd better not drop it while the disk is spinning. - vuke69, on 10/12/2007, -0/+3"They came out with a new drive with the SAS interface, which is backwards compatible with SATA."
You can use a SATA drive on a SAS controller, but not a SAS drive on a SATA controller. - cquinnd, on 10/12/2007, -0/+2To clarify; flash is notable for being fast on reads, but much slower than current hard drives when it comes to writing data back to the device.
- vuke69, on 10/12/2007, -1/+3As dark mentioned these are for servers not notebooks.
You can fit 8 or 9 2.5" SAS drives with trays in about the same space as 6 3.5" drives.
They use about half the power and put out half the heat.
They are usually a few percent faster.
Finally having 15k 2.5" drives is awesome. - smb3d, on 10/12/2007, -0/+2Once again, this is not a laptop drive.
- bioxeed, on 10/12/2007, -0/+2this isn't meant as a consumer product. It's more of an enterprise one. If you'd read the article you'd see it's being touted as a better performing (speed wise in certain cases) to the 3.5" drives. I doubt we'll see these in even the most extreme desktop replacement "notebook" let alone something like an ipod like some other commenters have said.
- JasonPrini, on 10/12/2007, -0/+2Is it faster than Flash?
- mgrucker, on 10/12/2007, -0/+2kind of odd how lots of Macs come with Seagate hard drives then...
- MrFoof82, on 10/12/2007, -0/+2For those of you saying "...iPod..." comments, keep in mind how the hard-disk based iPods work.
iPods basically have a good chunk of memory built into them in addition to the HDD. When you queue up a playlist, or even a random bunch of songs, it goes a few songs "ahead" to caches them all into memory. This prevents the disk from spinning constantly, which would be a huge battery drain. They just do a good chunk in one go to minimize how often the disk needs to be spinning.
You could put an abysmally slow disk in an iPod. The only thing it would really affect is access time for the first song, or when switching to something completely random, and then I'm sure it'd hardly be perceptible. - afwjam, on 10/12/2007, -0/+2read the article dip *****.
- shteinb, on 10/12/2007, -1/+3No reasonable company would EVER refuse to do business on moral grounds with a customer that has the buying power and demand that Apple has with the harddrives it uses for its IPods.
- AeroSquid, on 10/12/2007, -0/+2perfect hd for gaming laptops.. now if i can only figure out how to RAID them in there :)
- tmcdigg, on 10/12/2007, -0/+1Well, the space limitations make this drive impractical.. but kudos for trying..
When they can squeeze 500gb on the 2.5 inch sata2 drive with 64gb of hybrid flash space... call me!
Just making the drives smaller has a somewhat Japanese appeal.. (sony 80's/90s thing to miniaturize EVERYTHING ELECTRONIC) but for the rest of us?
Nope.. technically you could get enough throughput for a PMP to do HI-DEF video... barely, but would you want to on such a small screen and with so little hard disk space? Think People, think..
Also, for wannabe engineers.. it's not how fast the disk rotates.. it's what you get out of the "spin"
(ie throughput.. data in/data out) faster isn't always better.. there are other electronic configurations of substrate being investigated for possible hard drive advances.. but this is a tedious task, not always bearing fruit within the design reliability of todays equipment... (3-5 year window of guaranteed reliable operation... relatively speaking)
- BassJunkie, on 10/12/2007, -0/+1This looks quite cool, the company I'm working with atm recently took delivery of some new HP Proliant servers which all used the 2.5" HDD's and they are squeezing alot more HDD's into a smaller form factor, up to 8 or 9 mounted vertically! all this in a 2U form factor! This along with the fact that they ran on the new Xeon meant they where a lot quiter and one could then assume running cooler then the older servers which can only really be a good thing in a rack for of them!
- ez12a, on 10/12/2007, -0/+1"I know notebooks use 2.5" IDE"
The newest laptops use SATA
They came out with a new drive with the SAS interface, which is backwards compatible with SATA. These drives are for enterprise applications, not the everyday laptop. Though the 2.5" form factor would give some interesting ideas.. - tombomb, on 10/12/2007, -0/+1@ Petronski: I'm pretty sure it is in the 'If you have to ask, you can't afford it" Catagory.
- sinembarg0, on 10/12/2007, -0/+1Older Creative Nomads use 2.5 inch hard drives.
- Petronski, on 10/12/2007, -0/+1Any idea about pricepoint?
- mgrucker, on 10/12/2007, -0/+1why couldn't it be faster? They both spin at 15k rpm and they both have the same interface.
from the ***** article:
"Even with perpendicular recording, Seagate can only squeeze 36GB onto the Savvio 15K's platters. That results in fewer gigabytes per drive actuator, but it's the actuator speed that often limits performance in enterprise server environments. The fact that the Savvio 15K has less data per actuator than a 3.5" drive can actually make it faster, at least in applications that emphasize random access times rather than sequential transfer rates." - brivix, on 10/12/2007, -2/+2Oh yes, that would be very nice to be able to use my macbook all day without recharging it until the end of the day.
- Brows, on 10/12/2007, -0/+0Wow, that sounds great. I have 3 of the Cheetah's in my system now and they are really fast...can't wait to see they new drives at work. And yes they are noisy....but fast...
- drizek, on 10/12/2007, -1/+1Who says notebooks cant use SCSI?
Edit: nm, confused SCSI with SATA for a second. These would be awesome for mobile gaming though. - mcwizard, on 10/12/2007, -1/+1@merreborn, I agree with the first part of you comment, but for a dvr/pvr like a tivo, especially if it has more than one tuner or records HD content, a higher rpm drive will definitely show an improvement. Plus, a tivo is plugged into the wall so battery life is unimportant.
- SaumZ, on 10/12/2007, -1/+0Where I work, we use flash at the enterprise level as well as SAS drives.
I do enjoy both, but when it comes down to power consumption and ease of use, you can't beat flash. We currently use it in a piece of equipment called a Logomotion. We have a few of them, because we broadcast 8 TV station our of our location.
When it came to putting more logomotions in place, we simply got a card reader, and copied all of the data, made new card, changed a few things in the config, and it was up and running in about 15 minutes.
As for the overall speed, I would still use fast SAS for my NAS appliance or file server due to cost reasons. - gdragon, on 10/12/2007, -2/+1While the hard drive is a bottleneck, I don't think making faster spinning drives is the solution. The normal error rate for current hard drives is already too high. They spend most of the time doing error correction. Spinning the platters faster, like adding bit density, just increases the error rate.
A different approach is needed. Hybrid drives with lots of integrated non-volatile flash memory is a better solution. We should see more of these hybrid drives in the next year or two. Buying a 15K RPM drive is a waste of money when faster and more reliable hybrid drives are on the way. - TonyCubed, on 10/12/2007, -3/+1Will be interesting to see companies like Western Digital compete against this..
- hadak, on 10/12/2007, -3/+1sounds bad for battery life.
- kefler, on 10/12/2007, -3/+1@hadak -- yeah, I'd think that for a laptop this would be bad for the batteries!
- inactive, on 10/12/2007, -6/+0World's fastest hard drive? *****, Seagate. I think you just made that up. There's no way this could possibly be faster than a 15k 3.5" disk.
- deathhawk, on 10/12/2007, -9/+2for those of you who don't have a ***** clue what the interface is, SAS is Serial-attached SCSI, basically a scuzzy that plugs into a Serial ATA port. It's NOT what is in an iPOD, why the hell would an overrated mp3 player need a 15k rpm HD? besides, Seagate's way too good of a company to do business with Apple
- inactive, on 10/12/2007, -11/+2let the commenting up begin!
- kevnaca, on 10/12/2007, -15/+4You fail!
Ummm SAS? This is not a notebook drive people. Plus how noisy and unreliable would that drive be? - Samsong, on 10/12/2007, -15/+1Why is it the diggers are so enamored with hard drives?
- neuromancerzero, on 10/12/2007, -30/+3Isn't this the iPod HDD? Is there any chance of a disk LIKE this coming to an iPod. I just got a 80 gig one, but that barely fits my music. I have no videos on it. 150ish gigs sounds like what i need/want. I know this is too loud/hot/unreliable, but a 150 10,000rpm disk in an iPod would be fantastic.
- inactive, on 10/12/2007, -51/+5first! lol
