Leaked Intel Roadmap Shows 600GB SSD

An anonymous reader writes "Solid State Drives have been trying to fill the mechanical hard drive niche for some time now. The problem is that while flash memory is faster than a spinning platter, it is also much more expensive per gigabyte. Over the weekend details leaked about Intel's SSD roadmap, and what's most interesting about it is that the capacities of Intel's SSDs are going to increase in a big way. First off is a refresh to the high performance X25-M range of SSDs. Currently available in 80GB and 160GB models, these will be replaced by a new design, codenamed Postville, which will come in 160GB, 300GB and 600GB variants."

      The real issue is the cost difference per storage needs to be closer between the SSD and the Magnetic HDD. Translation is cost per megabyte.

      What would be good is to keep the old lines iff they can be manufactured less then the new technology. This is not to be expected due to the need to sell enough of the new technology to offset the research and development costs.

      There-fore the price is still too expensive and in particular for a Desktop computer. Even though they are better for a Laptop or Notebook the cost is still expensive for most users needs.

Still, that means I have 210 GB of stuff that I legitimately would want to carry around at all times, up from 160 GB two years ago when the last drive died, meaning that I pack on an estimated 25 GB per year of new material. And even that pales compared with people who do lots of movie downloading (legal or otherwise). (Yes, you could argue that those downloads could be put on an external drive, but that becomes a management headache when deciding what movies to bring with you on a trip, and... you get the idea.)

      With the upswing in downloadable content (both movies and software), the need for hard drive space is in a rapid upswing. If most people only needed 60 GB drives, you'd still be able to buy spinning drives that small, and the few percent of users who needed the bigger capacity would have to deal by adding external drives. Since we're not seeing any sign of the demand for larger drives slowing, I think it's safe to say that 64 GB is not enough for most users. I doubt it is enough even for most casual users.

      Speed is nice and all, but flash provides minimal speed boost during the 99.9% of the time that you're not booting or launching an application. You can get the same benefit with just a few gigs of flash cache for a lot less money than a full SSD.

      Flash memory is actually very cheap when you compare it with other memories made of silicon. In term of density (bit/nm^2), there is nothing better today: a flash cell is approx 3 times smaller than a DRAM cell. Additionally, today, a single flash cell can store up to 3 bits (Multi Level Cell, MLC as opposed to Single Level Cell, SLC). However MLC-based flash memories require more time to read and to program pages and have a lower life time.

      As the price of a chip roughly depends on its die area, it also makes flash the cheapest memory existing today. Today MLC Flash is ~11x denser than DRAM, while SLC is around 3x denser, that makes it approximately 11 times and 3 times cheaper than DRAM, respectively. Look at the prices of DRAM and Flash in your favorite store, you should get close to these ratios.

      In the future prices should lower as we make flash even denser. However there is a limit to this shrinking: in 3-4 years the price reduction of flash should slow down.

Then factoring in 25% efficiency on the wear leveling (that some blocks will be used up 4 times faster than with an ideal wear leveling algorithm), we arrive at 10,000,000,000 bytes of write capacity using these absolutely horrific numbers that you must be imagining before any blocks cant be erased. That is still an average of 5.5 gigabytes per day of writes over a 5 year period, equivalent to replacing the entire contents of the drive every 2 weeks.. and at the end of this period, the size of the drive merely begins to shrink because we assumed 25% wear leveling efficiency.

Not a problem now, but as time goes on this could result in more and more space being used on the system drive (which ideally should be pretty static in terms of volume usage, only changing when I add or remove applications).

The access time is quite irrelevant, for it counts only once. In this case the SSD is not the best answer. The 20 GB for an average 1080P movie file is way to expensive for that. So the answer is a spinner.

      Of course since laptop manufacturers do not incorporate SSD's in their motherboards and there is only one 2.5 inch slot available there are some issues with this. Hybrid drives are one answer, although I do not think they are the best answer.

      If buying a new laptop another option to consider is to sacrifice the optical drive, put a SSD in the main bay and demote the hard drive to the bay the optical drive came in. This does limit your choice of laptops though.

      There are multiple people out there (including Linus Torvolds, Jeff Atwood, and some random poster in this story) who say that changing from a magnetic hard drive to an SSD is about the biggest single upgrade you could make to a reasonable system today.

      I very rarely notice HDD based slow down on my current computer. I don't find myself tapping my thumbs and sighing at waiting for something to load (okay, outside of Photoshop, and the dramatically bloated and archaic iTunes).

      I'm sure, like all things, though, the second I upgrade; computers without a SSD will feel slow, and that couple ms will make me very impatient.

      I booted up my old C64 the other day, and realized that I had infinitely more patience than I have today. At the time, though, it didn't seem that bad waiting 2 minutes to load something. Same thing with going back to dial-up, 56k was BLAZING fast awhile back, and now it damn slow feeling.

      Of course, you wouldn't do this; you'd come up with some split between what should be on fast SSD and what should be on a slow magnetic media, and have one drive for each.

      I've been trying to efficiently split my data between drives for years, but most software doesn't play nicely enough yet to actually make this possible. My goal has always been a perfect split between relatively static data on a small, fast, drive, and dynamic data and media on a larger, slower, drive. Haven't managed to actually get this to work yet (with Windows at least). I agree though, SSDs would be perfect for this, when they drop in price a bit.

      Games are the worst, they really don't allow you to tell them where to plunk down anything outside of Windows default (which is generally actually pathed, and not just targeted to %USERDATA% or such).

      Not as much of a problem on Linux machines, obviously. And I have no clue how viable it is on OS X.

      When I can get a 200-300GB SSD for around $200, I'll grab it fast. Until then, the performance advantage isn't worth the cost.

      I still generally build my own computers with only AMD CPUs. I know Intel is a bit better right now, but the difference is less in the high-middle, than at the very high end. AMD generally always wins at cost/performance though. I never, EVER, build for the high end since the price is always inflated (the bleeding edge tax). Price increases exponentially, where performance increases incrementally.

      My last computer I settled for an AMD Phenom II x4 965BE, over whichever i7 I was looking at. Sure, the i7 was much better, but it also cost (with the price of a new mobo, and DDR3, around $500 more). Oddly, I could buy a premade Dell with the same specs cheaper than I could build an i7 box.

      I still wouldn't get a SSD yet, though, they are too cramped for being even my OS/applications drive, and to get a roomier one (over 100GB) you end up paying far more money than the performance increase is worth.

      Not saying that SSDs are pointless, just that their real world applications are rather limited right now, and most of them find use only with the same crowd that would cough up $600 for a graphics card that does 10% more than a $150 one. Some people find incremental improvement worth exponential price increases, these people are a minority. Yes, SSDs are also useful for netbooks, laptops with very limited use, and other people need fast access to limited amounts of data. They are not set to replace HDDs in desktops quite yet.

      Have you ever used one? Seriously?

      Putting a SSD in place of a rotating hard drive in a laptop will make a huge difference in how you view your laptop. Instead of sitting and waiting, and then waiting some more for things to happen or load in off of disk, it's basically instant. Boot times drastically reduced. Scanning or searching lots and lots of files, probably an order of magnitude faster.

      They are excellent solutions for the primary program/OS disk in any system. But bulk storage is not their strong point due to cost.

      On my Linux laptop, I haven't actually noticed much waiting. It isn't an issue. On my PC I've noticed a bit of churn on applications like Photoshop and Itunes. But SSD's haven't even got close to big/cheap enough to replace my primary drive (with 111GB of Windows, applications and games, all the media is on a separate drive already). I could by a 120GB SSD for $300 (as opposed to my $100 1TB drive), but I can't warrant the price, and in real life it would cost even more since I would want at least 200GB for growth room.

  30. Why I don't have an SSD drive by Anonymous Coward · · Score: 0

    Its not that they are more expensive or quibbling over their traditionally abysmal random write performance.

    Its the age old issue of oxide slowly being eaten away by electron tunneling causing the transister arrays to die.

    That and some condition lots of people are reporting where their SSD's get slower over time I don't understand. I think it has something to do with the way the wear leveling works but it seems at a glance to me to be more a function of lack of maturity.

    What is keeping me away from SSD is the fine print.. Intels "Guaranteed to work for 5 years at 20GB of write per day" ... Assuming a normal hard disk can sequentially write at a rate of 100MB per second (Many of us have disks which can do much better) this works out to 3 minutes worth of writes per day for 5 years. For my needs this renders the technology totally useless.
