  1. Re:In 5 years on SSD Price Drops Signaling End of Spinning Media? · · Score: 5, Informative

    The point of the shift to 4k sectors (e.g. the WD "Advanced Format" drives) is that the amount of space needed for error correction at ever increasing densities was entering into the bounds of diminishing returns. Larger blocks mean less error correction is needed and thus more storage space for a given platter density. Anand has a pretty good writeup on it here: http://www.anandtech.com/printarticle.aspx?i=3691

    Oddly enough... increasingly so.

    I'm lucky enough to have a spanking new SAN at work, a bunch of iSCSI nodes with dumb discs and smart software. We tier storage over SSD, 10k SAS and 7.2k SATA, the SSD mostly being utilised for performance-critical databases. SATA discs we reserve for file server LUNs, low-I/O VMs (most of them) and the intermediate tier of VM -> LUN -> Tape backups.

    As an aside, we choose to use RAID1 for SSD LUNs, as the RAID controllers can't keep up with the parity calculations and we saw a ~40% drop in IOPS when we used RAID6.

    If by "cheap" you mean the craptastic OCZ Core series, and the other SSDs of the same gen that used the god-awful JMicron controller, the "cheap" end of the SSD market is full of high-performance drives that don't choke on random I/O. As soon as Intel and Indilinx came out with controllers that were worth the sand they were printed on everyone started doing it, and we've now got a market where the performance delta between "cheap" and "prosumer" SSDs is much, much smaller.

    The vast bulk of the cost of the SSD is the flash, which is why if you can find someone still selling Core series SSDs they're only marginally cheaper than an SSD that's actually usable.

    IME the average laptop doesn't have WinCE, Ubuntu or games either. I don't expect your typical "home" laptop to start coming with an SSD for another year or two, but there's plenty of businesses that are drooling over the prospect of a) uber-fast laptop drives to make the loading of all that security bloatware bearable and b) laptop drives that are small and don't get stuffed full of files that should have been on the file server in the first place.

    My "workstation" laptop has a 500GB drive, and I wouldn't give that up for the world - I need the space for VMs. But my knockabout laptop is a toshiba T110 with an aftermarket 60GB OCZ drive in it. I don't have to worry about it being jiggled, there's a noticeable improvement in battery life and, obviously, I/O responsiveness is much improved (which helps make the laptop feel faster than its wimpy single-core proc would have you believe). Extra space for media or similar is provisioned more easily in the way of USB keys or SD cards.

    Moral of the story: IMHO people will go with a best-of-breed solution. Hard discs for people who need the storage, SSDs for people who don't. I think the article is right to assume that the majority of the laptop market can live inside 120GB.

  8. Re:Flat panel monitors all over again on Western Digital Launches First SSD · · Score: 1

    Indeedy - it's improved even more by products like FusionIO which can act like a colossal cache between your server and your SAN which get you your craptons of cheap storage plus lightning-fast IO for the bits that matter (assuming they're being used frequently enough).

    We were lucky enough to get a good deal and our SAN fabric is all over 10Gb iSCSI, hopefully to be upgraded to FCoE-capable kit in a year or so, and it's pretty easy to saturate that even with plain old SAS/SATA drives (when we got it we played about with a RAID0 array of about 25 drives just to see what the hardware would take).

    Your comment on "more like memory" is interesting though - I'm wondering if we'll ever return to the architecture of some mainframes where memory pages are indistinguishable from disc sectors and the two are used interchangeably - i.e. having a filesystem that appears to be an extension of system memory, doing away with the need for virtual memory altogether. IIRC memory pages for x86 and "advanced format" hard drives are both 4k now. Seeing as the performance delta between DRAM and some PCIe-connected NAND is much smaller than that of a spinning platter it might prove feasible.

  9. Re:Flat panel monitors all over again on Western Digital Launches First SSD · · Score: 1

    Disclaimer: I'm an SSD evangelist, I think they're great and probably the most important thing to happen to storage in at least the last decade.

    I was also one of those people who held on to their CRT's for an age because, for me at the time, TFT's provided zero benefit to me. However, a few years later I've found some displays that didn't cost much more than their good quality CRT counterparts used to, as well as being much smaller, sharper and providing almost-as-good colour fidelity.

    SSD's, on the other hand, provided immediate benefits to me as soon as I got my hands on one. Not having to wait for rotational disc latency and avoiding disc thrashing are both worth their weight in gold to me, and this goes double for enterprise stuff. Sure, it's great to have a laptop without a slow-ass drive, but with SSD's you can create a storage solution that'll outperform your 24U of short-stroked FC drives at, beleive it or not, a fraction of the cost. You even spend less time having to wrangle oracle and friends to get the most our of your hardware as you now have IOPS coming out of your ears, and more often than not you're limited by the interface rather than the array itself.

    Spinning platters aren't going to disappear for a long time yet, especially where storage space is king, and for purely sequential reads/writes where hard discs give you much more storage for your money. But anything where random IO and low latency is important, SSD has been delivering immediate benefits that I think are worth the money - especially in the enterprise where random IO becomes very important. YMMV of course, but I've met alot of people who dismiss SSD out of hand despite never actually having used it.

    Reason I started using them at home was due to video editing - not very useful for encoding when you can rarely outpace your CPU's capability to encode stuff, but for random seeking/non-linear stuff/extracting streams/muxing, SSD's are a boon. Depending on your workload you can even get away with using crappy SSD's that are shit at random workloads but awesome at sequential.

Try running a laptop off an SSD for a month and then go back to a mechanical drive - the apparent slowness will drive you crazy :)

    What with nVidia's unceremonious exit from the IGP market thanks to Intel's licensing, and the introduction of every-Intel-chip-comes-with-a-GPU, tech like this is a shrewd, and pretty essential, move by nVidia in order to remain relevant in the middle tiers. If people, whether on a laptop or desktop, can get the power savings of an Intel IGP with the ability to fall back on to a decent GPU, they'll claw back a good deal of marketshare from "prosumers" and the like. Conversely, ATI has made incredible improvements in the idle power savings of their GPUs, so it remains to be seen if process technology makes the software complexity worth it.

    The only question is whether they'll stick at it in terms of driver support. IIRC their hybrid power initiative lasted only for a couple of card revs a year or two ago. Didn't RTFA but suspect this'll only work on Win7 where the WDDM allows for two different GPU HALs whereas Vista did not.
