All Indilinx Drives Are Built Alike

G.Skill, OCZ, Super Talent and Patriot all sent their Indilinx MLC drives in for review. If you take the drives apart you see that most are the very same on the inside, despite differences externally:


From Left to Right: OCZ Vertex Turbo, OCZ Agility, Patriot Torqx, G.Skill Falcon and Super Talent UltraDrive GX. Only the Super Talent drive uses a different PCB design.

Even the packaging doesn’t appear to vary much between manufacturers; that part I don’t really understand. All that seems to change is the artwork on the outside.

There are some minor differences between drives. Patriot ships its Torqx with a 2.5” to 3.5” drive bay adapter, a nice addition. The Torqx also comes with a 10 year warranty, the longest of any Indilinx based manufacturer. OCZ is next with a 3 year warranty, followed by Super Talent and G.Skill at 2 years.

Indilinx is still a very small company so it relies on its customers to help with validation, testing and even provide feedback for firmware development. As far as I can tell, every single Indilinx customer gets the same firmware revisions. Some vendors choose to rename the firmware revisions, while others do not. OCZ calls its latest stable firmware 1.30, while G.Skill, Super Talent and Patriot call it 1571.


The Indilinx Barefoot controller (right), powered by an ARM core.

Of all the Indilinxites, OCZ and Super Talent work closest with the controller manufacturer. In exchange for their help in manufacturing and validation, OCZ and Super Talent also get access to the latest firmwares earlier than the rest of the manufacturers. Ultimately all manufacturers will get access to the same firmware, it just takes longer if you’re not OCZ or Super Talent.

You no longer need to use a jumper to upgrade your firmware, provided that you’re already running fw revision 1275 or later. If you have a previous version you’re pretty much out of luck as you need to upgrade to 1275 first before upgrading to anything else, and none of the manufacturers make it easy to do. Some don’t even offer links to the necessary firmware you’d need to jump to 1275. Thankfully pretty much anything you buy today should come nearly up to date, so this mostly impacts the original customers of the drive.

Performance, as you’d expect, is the same regardless of manufacturer:

There's normal variance between drives depending on the flash/controller, that's why the OCZ Vertex is slower than the Patriot Torqx here but faster than the Super Talent UltraDrive GX. The manufacturer and size of the flash has more to do with determining performance. Samsung is used on all of these drives but the larger the drive, the better the performance. The 256GB model here will always be faster than a 128GB drive, which will always be faster than a 64GB, etc...

All of the drives here use the same firmware (1571) except for one of the Super Talent drives. That drive is using the beta 1711 firmware with TRIM support that was pulled.

When it comes to the best overall package, I’d say Patriot’s Torqx is the nicest for a desktop customer. You get a 3.5” adapter bracket and a 10 year warranty (although it’s difficult to predict what Patriot’s replacement strategy will be in 10 years).


The Patriot Torqx bundle, complete with a 2.5" to 3.5" adapter.

Prices vary a bit between manufacturers, although most of the more expensive drives here have a $30 rebate to bring their prices in line:

  Price for 128GB
Corsair Extreme Series $384.00
OCZ Agility $329.00
OCZ Vertex $369.00
OCZ Vertex Turbo $439.00
Patriot Torqx $354.99

 

OCZ does do some unique things that the other manufacturers don’t such as deliver an overclocked drive (Turbo) and a drive with slower flash (Agility). There’s a Mac Edition of the Vertex, unfortunately it’s no different than the regular drive - it just has a different sticker on it and a higher pricetag.

    Installing a non-OEM drive is not going to void the warranty on the rest of the system. And as the other commenter posted, your problem isn't reliability, it's performance. Anand's excellent article shows the performance dropoff of the Samsung drives.

    Finally, if you do get another SSD (or still have one currently), definitely disable Prefetching. SuperFetch and ReadyBoost are read-only as far as the SSD is concerned, but Prefetch optimizations do write to the drive. It selectively fragments files so that booting the system and launching the profiled applications do as much sequential reading of the HD as possible. Letting prefetch reorganize all those files is bad on any SSD, and extra bad on one where you're seeing write penalties.

    ...

    And "One More Thing" (apologies to Steve Jobs)! Check out FlashFire (http://flashfire.org/)">http://flashfire.org/). It's a program designed to help out with low end SSDs. At a very basic view, what it does is use some of your RAM as a massive write-coalescing cache and puts that between the OS and your SSD. It collects a series of small random writes from the OS and applications and tries to turn them into a large sequential write for your SSD. It's beta, and I've never attempted to use it, but if it works for you it might be a life-saver.

    Thanks again for the feedback, Ardax. Duly noted about the Dell warranty. They will continue to warrant the rest of the laptop, AFAIK, even if we install a 3rd party drive.

    Can you point to your source on the statements about how prefetch fragments files on the drive? Nothing I've read about it describes it as write intensive.

    I'd like to point out that this SSD is not a low-performance unit, the kind Flashfire is supposed to help with. It was one of the fastest drives available last year, before Intel's drives came out and set the curve. When its performing normally, this system boots Vista in ~30 seconds. Its uses SLC flash with an order of magnitude more write cycles than comparable MLC-based drives. Were standard Windows installs the cause of these failures, we would have heard about MLC drives failing similarly within the first month.

    Its also a business machine so loading alpha rev software on it for performance optimization isn't really an option. The known issues on Flashfire's site make it not worth the risk until its more mature.

    One possible work-around:

    I know that, for instance, if I buy a drive from Dell for one of my servers, that drive is covered under the Dell warranty for that server.


    Dell sells a Kingston re-branded Intel X25-E drive and a Corsair Extreme SSD drive.
    The Corsair Extreme series is an Indilinx SSD drive:

    I don't know if this applies to non Dell-branded products that Dell sells, but it might be worth looking into.

    "Disable Defrag, SuperFetch, ReadyBoost, and Application and Boot Prefetching"

    This is keen advice, especially for the OP's laptop SSD usage scenario. Definitely disable these services.

    I'd also suggest disabling Automatic Restore Points on the SSD Volume(s) from the System Protection task in the "System" Control Panel. When enabled this setting can generate a lot file I/O and will add to block fragmentation and eventual garbage collection. http://en.wikipedia.org/wiki/System_Restore">http://en.wikipedia.org/wiki/System_Restore

    Regular external backup and disk imaging should be just as effective, without the resource penalties.
  • heulenwolf - Friday, September 4, 2009 - link

    TGressus, thanks for the feedback. With the exception of defrag, however, I can't find any real-world data about these services that leads me to beleive they place undue wear on the SSD. Sure, disabling them may free up marginal system resources for performance operation, but I haven't heard anything leading me to believe they're the cause of the repeated failures I saw. Since none of those features are check-box-disable-able items (again, beyound defrag) - they seem to require custom registry hacks - I'm not comfortable performing them on my business machine purely for performance optimization.

    I guess I've narrowed it down to options A or C from my original question:
    A) Am I that 1 in a bazillion case of having gotten a bad system followed by a bad drive followed by another bad drive
    B) Is there something about Vista - beyond auto defrag - that accelerates the wear and tear on these drives
    C) Is there something about Samsung's early SSD controllers that drops them to a lower speed under certain conditions (e.g. poorly implemented SMART diagnostics)
    D) Is my IT department right and all SSDs are evil ;)?

    Drive reliability does not appear to be a problem in your case. There is nothing in you description that indicates the drives failed, only the performance dropped to unacceptable levels. That is exactly the situation described by Anand's earlier tests of SSDs, especially with earlier firmware revisions (any brand) or with heavily used Samsung drives.

    I presume your swap space (paging file) is on the SSD? The symptoms you describe would occur if writing to the swap space (which Windows will do during boot up/login) is slow. You might be able to regain some performance and/or delay the reappearance of symptoms by simply moving your swap space off the SSD.

    For your purposes, it sounds like your best solution would be to switch to an Intel or Indilinx drive, probably an SLC drive, but a larger MLC drive might work well also. Dell won't warranty the new drive, but it won't "void" your warranty either. You'll still have the remainder of the warranty from Dell on everything except the new SSD, which will be under warranty from the company making the drive. If you have a support contract with Dell, they might try to point to the non-Dell SSD as an issue, but at least with the Gold/Enterprise support group, I have not found Dell to do that type of finger pointing.

    The Intel drives are now good at automatically cleaning up with repeated writing, while with an Indilinx drive, you may need to occasionally (perhaps every 6 months) run the "Wiper" utility to restore performance.

    Also, you indicate your drive is about 3/4 full, if you can reduce that, you may see less performance hit also. You can do that by removing some data, moving data to a secondary drive (HD or SSD), or buying a larger SSD.

    If you're working with large data files that you're not accessing and updating randomly (e.g. you're not primarily working with a large database), then you might benefit from having your OS and applications on the SSD, but use a HD for your data files and/or temp/swap space. Of course, make sure you have sufficient RAM to minimize any swapping regardless of whether you're using a HD or an SSD.

    gstricker - duly noted about the Dell warranty.

    I have to disagree that drive reliability is not the issue for two reasons, only the first of which I'd mentioned before:
    1) Dell's diagnostics failed on the SSD
    2) Anand's test results show major slowdowns, but not from 100 MB/s 5 MB/s for both read and write operations. No matter what I did, even writing my own scripts to just read files as fast as it could, I couldn't get read access over 10 MB/s peak with average around 5. Its like the drive switched to an old PIO interface or something. The kinds of slowdowns in Anand's results do not lead to 15 minute boot times.

    Its a laptop with only one drive bay so, yes, page file is on the SSD and a second drive isn't really an option. According to the windows 7 engineering blog, linked by Ardax above, SSD's are a great place to store pagefiles. Since the system has 4 GB of RAM, its not like the system has undue swap writing going on.

    I can't imagine Samsung or Dell selling a drive with a 3 year warranty that would have to be replaced every 6 months under relatively normal OS wear and tear (swapping, prefetch). Vista was well past SP1 at the time the system was bought so they'd had plenty of time to qualify the drive for such uses. They'd both be out of business were this the case.

    Agree that the best bet would be to switch brands but I'm kinda stuck on what's wrong with this one. Thanks for the feedback.
  • gstrickler - Thursday, September 3, 2009 - link

    That it failed Dell's diagnostics might indicate a problem, but do you know for certain that Dell's diagnostics pass on a properly functioning Samsung SSD? I don't know the answer to that, but it needs to be answered.

    While Anand's tests don't show 90% drops in performance, his tests didn't continue to fragment the drive for months, so performance might continue to drop with increasing fragmentation.

    More importantly, I've experienced problems with the Windows page file before, it does slow the system dramatically. Furthermore, the Windows page file does get written to as part of the boot process, so any performance problems with the page file will notably slow the boot, 15 minutes with Vista is not difficult to believe. While I haven't verified this on Vista, with NT4/W2k/XP the caching algorithm will allow reads to trigger paging other items out to disk, so even a simple read test can cause writes to the page file if the amount of data read approaches "free RAM". Again, performance problems with the page file could dramatically affect your results, even for a "read-only" test. Don't be so certain of your diagnosis unless you've eliminated these factors.

    You should try removing the page file (or setting it to 2MB), then see what happens to performance.
  • heulenwolf - Friday, September 4, 2009 - link

    I had the same thought about Dell's diagnostics. I've run them again on the latest refurb drive and found that it passes all drive-related tests. Unfortunately, Dell's diagnostics simply spit out an error code which only they hold the secret decoder-ring to so I have no idea what the diagnosis was. This result isn't conclusive but its another data point.

    To more fully describe the testing I did, I wrote a script that generated a random data matrix and timed writing it to file. I then read the data back in, timing only the read, and compared the two datasets to ensure no read/write errors. I looped through this process hundreds to thousands of times with file sizes from 4k up to 50 MB. Since I was using an interpreted language, I don't put much stock in the performance times, however, I was using the lowest level read and write functions available. Additionally, my 5-10 MB/s numbers come from watching Vista's Resource Monitor while the test was running, not from the program. No other measured component of the system was taxed so I don't think the CPU or being near the physical memory limit, for example, was holding it up.

    I have not found many articles on the net about SSDs and this one is even easy to understand.

    The only negative part about this article is the Lenovo T400 I am typing on (it has a Samsung drive :( ) And I have to agree, startup times are nothing special.
