OCZ Vertex 3 Fail: “Runtime corruption detected on SSD” and why SSD drives are not safe yet.

After almost 9 months with the OCZ Vertex 3 SATA-6GBPs (read about my OptiBay two-drive setup) and mostly no issues, the drive died on me. Starting with several GSOD (Grey Screens of Death) on my OSX Lion MacBook Pro, the drive became more and more unreliable.

Nov 28 18:30:43 mbp kernel[0]: hfs_swap_BTNode: record #55 invalid offset (0x9B46)

It was getting slower and slower, reporting tons of errors in the Console.app. Then, it did not reboot anymore. Even in an external USB drive enclosure the drive did not mount anymore. Contacting OCZ about this issue, they sent me an RMA number right away and told me they will replace the drive. Does this mean our data is not safe in SSD? What can we learn from this?

First of all, it is a myth that SSDs are more reliable than hard drives. Secondly, they are not even fully supported on OSX yet (see Should I use Trim Enabler on Lion for the OCZ Vertex 3? No!) - at least if you install the drives yourself (which is also what I would suggest, since Apple does not offer any decent SATA 6GBPs drives yet).

So where is the proof, you ask?

Proof #1: The Hot/Crazy Solid State Drive Scale (via Coding Horror)

Super Talent 32 GB SSD, failed after 137 days
OCZ Vertex 1 250 GB SSD, failed after 512 days
G.Skill 64 GB SSD, failed after 251 days
G.Skill 64 GB SSD, failed after 276 days
Crucial 64 GB SSD, failed after 350 days
OCZ Agility 60 GB SSD, failed after 72 days
Intel X25-M 80 GB SSD, failed after 15 days
Intel X25-M 80 GB SSD, failed after 206 days

As a commenter put it: "Average life of SSD = 227.375 days (based on Wills' data)" - which is also what I can confirm.

SOLUTION: Backup early, backup often. Don't rely on the SSD and make two local backups plus one backup in the cloud.

Proof #2: long-term study of SSD failure rates (via Tomshardware)

SSD vs HDD Failure Chart

SOLUTION: Buy drives that come with a very long warranty. Be prepared to let your drive replace for several times.

I am still waiting for my replacement OCZ Vertex and I will benchmark how fast it will die again. Since OCZ told me, it can take up to three weeks for my replacement to arrive, I bought myself a Seagate ST750LX003 750 GB SATA 600, Momentus XT, 8 GB SLC - it's a hybrid 750GB HDD with an 8GB SLC cache. The drive shifts data that is used often in the 8GB SLC SSD space automatically. While the SSD part of this hybrid drive can also fail, the data won't be lost and it will suffer just some minor speed loss (if it fails, since SLC is said to be more reliable than MLC chips). While this disk is now my main startup disk, i will go back to using the OCZ Vertex 3 again, once the replacement arrives. I just need to backup regularly - the speed gain is really worth the trouble.

Facebook “Open Compute” Server tested by Anandtech

Facebook designed an AMD and an Intel motherboard - all manufactured by Quanta. Their main aim was to make more efficient and cheaper servers: “The result is a data center full of vanity free servers which is 38% more efficient and 24% less expensive to build and run than other state-of-the-art data centers.” The efficiency of the voltage regulators: 94%. Everything was removed, that was not absolutely necessary: the motherboards have no BMC, very few USB (2) and NIC ports (2), one expansion slot, and are headless (no videochip).

Facebook had 22 Million active users in the middle of 2007; fast forward to 2011 and the site now has 800 Million active users, with 400 million of them logging in every day. Facebook has grown exponentially, to say the least! To cope with this kind of exceptional growth and at the same time offer a reliable and cost effective service requires out of the box thinking. Typical high-end, brute force, ultra redundant software and hardware platforms (for example Oracle RAC databases running on top of a few IBM Power 795 systems) won’t do as they're too complicated, power hungry, and most importantly far too expensive for such extreme scaling. (quoting Anandtech)

"The AMD servers are mostly used as Memcached servers, as the four channels of AMD Magny-cours Opterons 6100 are capable of using 12 DIMMs per CPU, or 24 DIMMs in total. That works out to 384GB of caching memory."

It remains unclear, when or if that server hardware will be available for purchase - but it looks like there will be some cloud/datacenter providers jumping on the idea of the open compute servers, so it might be possible to rent them.

RAW Video for DSLR with Magic Lantern and Black Magic Hyperdeck Shuttle (vs. Atomos Ninja): 5D MKII, 550D, Rebels

SLR Film making got even more exciting: with the availability of HDMI recorders, RAW Video footage can be recorded to get the maximum out of your Canon 5D MKII or other camera compatible with Magic Lantern. Standard Firmware does not output a "clean" HDMI signal, at least not for Canon cameras; the Panasonic GH2 produces a clean HDMI output, as noted by Philip Bloom (!).

What are currently recommended HDMI field recorders?

1. Black Magic Hyperdeck Shuttle (RAW Video)

Black Magic Design Hyperdeck Shuttle

* Product information page/ manufacturer: Black Magic Design
* Discussion on the Magic Lantern User Group: hyperdeck shuttle

Pro:

  • Very Cheap: ($339.99 in the USA, 299€ in Europe
  • Records UNCOMPRESSED (!) RAW Footage from HDMI Out.
  • Cons:

  • Expensive in usage: 15 minutes uncompressed (1.6 GB/s) = 180GB
  • SSD drives NOT included, so you might need to calculate in some OCZ Vertex 3 SSDs in your budget
  • No Video Monitoring on the device itself. You might need to buy an external monitor, such as the Liliput external HDMI monitor (starting at $169 in the USA and 186€ in Europe)



    2. Atomos Ninja - Portable HDMI Recorder (ProRes)
    Atomos Ninja HDMI Recorder for almost RAW Video (Apple ProRes)

    Pro:

  • Smaller files, since it is no real RAW footage but Apple ProRes: 6 hours ProRes 422 (HQ) (220 MB/s) (16.5 Hours with 750GB Disks)

  • Monitoring included! 4.3” diagonal, 480x270 resolution
  • Cheap usage, since Hard Drives can be used! (though, the initial price is higher:
  • Less storage space needed
  • Supports two Hard Drives or SSD-Disks.
  • Firewire 800, USB-2 and USB-3
  • Continous Battery: two power cells to guarantee uninterrupted usage

    Cons:

  • Apple ProRes and no real RAW footage (this can be a good thing, as you are saving tons of money and storage space)
  • No ProRes for Windows users yet; Apple users might need to get Final Cut, since Apple ProRes is included in FCP Studio


  • Conclusion:
    Unless you are super-rich and have tons of money to spend for Solid State Drives and a RAID Array, you should get the Atomos Ninja. Besides the actual device, you also get a monitoring solution and have a true portable device, that creates files usable with normal hard drives. Overall cost is much lower and there should not be a really visible difference from ProRes to RAW footage. If you are into Bokeh Porn, you might want to spend your money in the Black Magic Hyperdeck Shuttle.

    Keep in mind, there are currently some issues with HDMI out an Magic Lantern: there is a video on the 5D MKII's 1080i out and also some discussions going on in the Magic Lantern Forums, because some processing needs to be done to get actual usable files. Actual resolutionis 12-19% less (depending how you do it) but still the results are awesome - especially in low light situations. Maybe we will get real clean HDMI out with the Canon EOS 5D MKIII.

    Should I use Trim Enabler on Lion for the OCZ Vertex (3)? No! (Benchmarks inside)

    We recently blogged, after purchasing two OCZ Vertex SATA3 Drives (240GB) and inserting them with an Optibay setting (2 Drives in one MacBook Pro; see our previous post: 2011 Macbook Pro and SATA III 6Gbps, Optibay: two HD drives – setup explained).

    We also blogged that enabling TRIM is a good thing, although it seems that it seems to be not necessary on Sandforce based chipsets.

    Since we still were experiencing freezes and Sandballs on our Mac OSX Lion 10.7 SSD Setup that were actually not related to TRIM, also the system did not feel as snappy anymore.

    Conclusion: don't use TRIM on OSX Lion 10.7, if you are using a Sandforce based SSD. Revert to the original driver and not only the Beachballs will go away, but also the system feels snappy again. See the below Benchmarks for real-life results (since AJA System Test does not work on internal drives, we can recommend using XBENCH to verify the figures for you).

    Mac OSX Lion 10.7 System Freezes: kernel: IOSurface: buffer allocation size is zero (console message)

    Some people experience system freezes on Mac OS X 10.7 Lion, but also on Snow Leopard: kernel: IOSurface: buffer allocation size is zero.
    The Error is visible with Console.app ("All Messages" respectively "kernel.log")

    To reproduce the issue:
    1) click on "Clear Display" in Console.app
    2) go to http://www.adobe.com/software/flash/about/ and the error will show up in the console.

    The error must be Flash related. Sometimes, the whole System is unresponsive, freezing everything but the mouse. There is no official response from Adobe or from Apple, so we can only hope and wait. Please check your Console.app for this error and respond to any of the existing discussions.

    Screen Shot 2011 07 28 at 11 52 25

    [Update] the error message also seems to have surfaced in 10.6.4 already, as visible in the Apple Discussion Forums

    [Update] installing the Adobe Flash Player 11.0 from Adobe Labs seems to at least minimize the freezes, but still the console messages appear.

    [Update] i posted a poll on insanelymac to see which browsers and systems are affected. please also post your results there!

    [Update] the new Beta 2 11.0.d1.98 of the flash player is out (thanks JP Hansen)

    [Update] The Flash Player 11 is officially released. It seems though, that not all issues are resolved with Mac OSX Lion compatibility.

    [Update 23.12.2011] more than 6 months after the issue was reported, (and we have Apple Mac OS X 10.7.2 and 10.7.3 in beta) there is still no update on this issue from Adobe. Please write your concerns to the Adobe Forums in the existing thread to have them fix the issues! Especially for SSD owners this is unacceptable!

    Existing Discussions:

    * Nanofunk.net discussion thread in the Adobe Flash Player Forums
    * Thread in the Apple Support Communities Forum
    * Thread on MacRumors Forums regarding Lion Freezes with kernel: IOSurface

    [Update] I posted to the Adobe Bugbase with a bug description. Hope they will respond now.

    Promise Pegasus Thunderbolt RAID system for high-speed data demands: 6x3TB for a total of 18TB (mod)

    [Edit 23.12.2011] CAUTION! People trying the below mentioned modification of the Promise Thunderbolt reported issues and data loss. Please consult the Promise Support if you are planning to do modifications or already did!

    [UPDATE] with the announced Hitachi Deskstar 7K4000 4000GB(4TB), 5K4000 as well as the 4TB Seagate Barracuda XT a total of 24TB could be reached when modding the Promise Pegasus just replacing the 2TB drives it comes with. 5TB HDDs are reported arriving in January 2012. Read our updated Article: Caution with Promise Pegasus Thunderbolt RAID 6x3TB (18TB) or 6x4TB (24TB) modification. 6x5TB (30TB) possible as of January 2012?


    The Promise Pegasus is the most "promising" hardware for enthusiasts and pro users, since it offers really fast transfer speeds, even topping the OCZ Vertex 3 SATA 6Gbps internal SSD on Macbook Pro computers.

    Delivering over 800MB/s of disk performance, Pegasus is compatible with Mac systems with Thunderbolt

    31ZnpSUvKsL
    41CYNnbqz3L

    Compare the Promise Pegasus R4 (4x 2TB) and the Promise Pegasus R6 (8x 2TB). Of course, if you want to pimp your pegasus, you can replace the internal drives with different ones.

    Internally Promise uses a PMC Sierra PM8011 8-port SAS-2 RAID controller. This is an 8-lane PCIe Gen 2 controller with eight SAS/SATA 6Gbps ports. On the R6 obviously only six of those ports are functional. The PM8011 has an embedded 600MHz MIPS processor and is paired with 512MB of DDR2-533. (via Anandtech)

    DSC 4155

    Possible replacements and hacks for the Promise Pegasus:

    * replace the internal hard drives with SSD drives: at the current date this still has stability issues. We are waiting for updated drivers or a response from Pegasus about the current freezes and issues with SSD drives. If you really have to test it out, make sure you get 6Gbps SSD drives. 2.5inch drives will also fit in the caddy.

    * replacing the internal drives with 3TB drives: this is a confirmed and stable way of pimping your pegasus drives. Pegasus comes with 2TB Hitachi Deskstar 7K3000 drives, so make sure you are getting 3TB drives from the same brand. We can recommend the Hitachi 3TB 7200RPM drive, but also we can confirm the Pegasus runs with the Western Digital 3 TB SATA II Intellipower 64 MB Cache Bulk/OEM Desktop Hard Drive and the SEAGATE Barracuda XT 3 TB SATA 6.0 Gb-s 64 MB Cache. Just keep in mind, not to mix up brands: you should get 6 times the same hard disk for the most stable system.

    * replacing the internal drives with SAS 6Gbps Hard Disks: while this would render the promise pegasus a real pro system that is rock stable, drives should be used, that offer a compatible SAS-connector. Since SAS-drives are generally compatible to SATA-connectors, we can generally recommend the Seagate Constellation ES.2 3 TB Internal Hard Drive SAS 600 7200rpm 64MB

    Conclusio: The Promise Pegasus is a fast solution for great read/write speed plus the extra feature of having the possibility to daisy-chain more Pegasus devices together, to increase the space when needed. Compared to the Data Robotics DROBO PRO System, it only offers 1-drive fail (1 drive can get corrupted, if 2 fail your data is lost) while the DROBO offers dual drive redundancy. Also, the DROBO PRO supports different sized drives, while you can only put drives of the same size (and it is recommended to also only use the exact same drive models) in the Promise Pegasus.
    Overall, nanofunk is recommending the Pegasus R4 and R6, because of its faster speed and possibilty to enhance the system. Since we had our DROBO PRO replaced twice (the unit itself was faulty) we are currently fully in favor of the Promise Pegasus.

    2011 Macbook Pro and SATA III 6Gbps, Optibay: two HD drives – setup explained

    Since we recently purchased two 2011 MacBook Pros (with lots of issues, as previously reported) we were wondering if SATA III 6Gbps drives would be supported. The short answer is YES, the longer answer is: only on the original Hard Drive port. Here are recommendations on which drive setup is best  suited for getting the maximum out of the 2011 Apple machines.

    Which type are you?

    • the collector: two 750GB SATAII Drives
    • fast, but not furious: 256GB SSD SATAIII drive + 750GB HDD in the optical drive slot
    • the caretaker: 256GB SSD SATAIII drive + 500GB SATAII hybrid drive in the optical drive slot
    • speed enthusiast: 256GB SSD SATAIII drive + 256GB SSD SATAII drive in the optical drive slot
    • humongous and rich: 512GB SSD SATAIII drive + 512GB SSD SATAII drive in the optical drive slot

    The recommended steps are to select your setup, get an OptiBay, choose an external casing for your optical drive and get your hands dirty. Read our recommendations and tell us which type you are!

    The new MCE OptiBay was created for users who want as much hard drive capacity as possible inside their MacBook Pro, MacBook, PowerBook G4, iMac, or Mac mini. Period

    Best Cases and Casemods for your Hackintosh

    Having a hackintosh can be a good experience, once you get it up and running. According to the geekbench result browser, there are some fast ass-kicking machines out there. Unfortunately, one thing not benchmarked by geekbench still sucks big time: the case. How to find the perfect case for hackintosh computers?

    1. Get an original Apple Mac Pro Case (Enclosure/ Chassis) or alternatively: an Apple Power Mac G5 Case to tinker with

    You can find Apple Mac Pro Cases (case only) via ebay, although they might be quite pricy. Another option is to search for Apple Power Mac G5 Cases instead, which are sometimes selling for a few bucks (most of the people interested are searching for "Mac Pro" and not for "Power Macintosh"). So while there might be some tinkering required, still the Apple Power Macintosh G5 Case is a very fine piece of casing. (see a howto for G5 Casemodding on Youtube)

     

    2. Almost as good as the "original": Lian Li PC-V1000 computer case

    You might get lucky and find the Lian Li PC-V1000 computer case on ebay - unfortunately I did not find any other ways of ordering this awesome case somewhere else.

     

     

     

    3. DIY your own.

    There are some impressive CaseMods out in the wild (e.g. the Hackintosh Jr. Case Mod). While this might be a lot of work, you will earn lots of (digital) street creds for your "almost impossible mod". Enter hardforum.com if you are brave.

    hackintosh: XPC Bootloader Can Boot Mac OS X 10.7 Lion

    "lion is booting with some old xpc version" ~ Netkas

    Some people are claiming to boot the recent Mac OSX 10.7 Lion with the XPC Bootloader project. More and more voices are popping up, so I am just pointing in the right direction, since "Any and all information about downloading and installing Lion, as well as any details are under Non-Disclosure Agreement from Apple.". You probably find updates on Netkas' Blog as well.

    via fffff.at: "The 2nd edition of the SPEED SHOW presents again a wide selection of pop.net.art pieces and addresses various developments of performance related but still screen based art works. Most interaction and communication on the web bears it’s very own performance character. One could say Facebook is a huge mass performance piece. net.art in it’s classic form could be considered a performance by interactivity as well. In recent years artists from different fields work increasingly in a mix of performances and digital interventions. In some cases the screen itself, the beholder of the pixel is subject to fluctuations. In other works the performance is acted out by a hysterical mass or just by the code."

    Owl Project: electronic musical instruments made of wood

    Owl Project is a collaborative group of Manchester based artists who share interests in human interaction with technology and process led art. Over the last few years they have become known for a distinctive range of wooden musical and sculptural instruments that critique human interaction with computer interfaces and our increasing appetite for new and often disposable technologies.
