OCZ Vertex 4 128GB SSD Review and 1.4RC FW Comparison – SSD Steroids for Your Vertex 4

If you thought the most exciting improvements with OCZ’s new Vertex 4 firmware were reserved for the 256GB and 512GB models, you’d be wrong. As it happens, the most interesting and substantial performance improvements are to be had with the 128GB Vertex 4.

We happen to have a 128GB Vertex 4 on our bench in order to find out what makes it and the new Vertex 4 1.4 Release Candidate firmware worth a look.


The Vertex 4 possessed many desirable characteristics at launch, but also many puzzling attributes. For example, despite it’s brutal speed, it could barely compete with it’s contemporaries in Vantage testing. New firmware addressing some initial shortcomings was promised, and now OCZ has delivered. Though still in a pre-release stage, OCZ has made the upgrade available for the adventurous enthusiast. Does the new firmware increase performance? Is it worth the upgrade from a stable 1.3FW release to a release candidate? To find out, we’re putting a 128GB Vertex 4 though the gauntlet with both firmwares.



The 128GB Vertex4 isn’t the fastest member of the new OCZ flagship family. With sequential reads of up to 535MB/s and sequential writes up to 200MB/s, the “junior 4” falls behind the performance of it’s big brothers. All three are said to have nearly the same random performance though: 85,000 random write IOPS and 90,000 random read IOPS (95K for the 512GB). Each is also given a “max IOPS” figure: 120,000. Digging a little deeper, it appears that this number is generated from 512 byte random accesses at high queue depths.

The 128GB Vertex 4 SSD is currently listing at Amazon for $149.99blank, or around $1.20 per usable GB. The 256GB and 512GB units can be found in the neighborhood of $300blank and $650blank, respectively. Each Vertex 4 is given a five year warranty to bring it in line with Intel, Plextor, and OWC’s premium offerings.


The 4’s Everest 2 platform is composed of a Marvell processor strapped with OCZ’s 1.3 version firmware. Riding shotgun on the PCB is 1024MB of DRAM, or put another way, more memory than came standard on most laptops before 2005. The 128GB doesn’t make use of all that cache, and only the 512GB model makes use of the whole GB. The package is completed with sixteen 64gbit ONFi NAND modules, each 8GB in capacity. After formatting, users are left with a little over 119GB of the 128GB onboard, which amounts to zero percent over-provisioning.


After voiding the warranty and removing the case screws, the PCB is available for pictures. The plastic housing hides one of the most intricate and visually interesting PCBs around, packed to the gills with traces and surface mount components. The Indilinx-badged controller is surrounded by eight flash packages and 512MB DRAM. Given some of the characteristics of the drive, the controller could be a variant of the new Marvell 88SS9184.


The opposite side, just as visually interesting, holds the remaining 512MB Micron DRAM IC and the other eight Intel 29F64G08ACME3 NAND packages. Some drives may have identical Micron flash in the future, but so far most shipping drives appear to use the Intel-branded IMFT flash. Either way, the Vertex 4 will have 3,000 PE (program/erase) cycle flash in it, regardless of whether it says Intel or Micron on the flash.

If you compare the PCB shots from this sample and the original Vertex 4 512GB we reviewed in April, you’ll notice some visual differences. The golden traces are much more visible and the Indilinx branding on the controller is not as white on this 128GB version.

The V4 makes good use of the 3K PE cycle NAND with it’s 128bit ECC (Error Correcting Code). With the more advanced ECC engine, the Marvell processor and Indilinx firmware should be able to get every last bit of endurance out of lower-PE flash.

    i wanted to see some updates on 256gb drive lol but this is great. the HD tune showing a weird behavior though, would probably wait for the releases of next firmware, which no one knows when..

    “once you’ve upgraded to 1.4RC. Flashing to 1.4RC involves a destructive update (all data is wiped in the process), and the drive must not be the primary system drive.”

    im understand why. flashing to 1.4RC involve destructive update,
    but im not understand, why the drive, cant act as the primary system drive?
    pls explained?

      You cannot upgrade while it is a boot drive or it will destroy your system. You can upgrade and then use it as a boot drive.

      I think the author was saying if you’re running this drive right now, and it’s running 1.3, and your operating system is running on the drive running 1.3, you can’t update to 1.4, because flashing it would wipe out everything on the drive running 1.3, including the operating system.

    Many people reporting Vertex 4 is having issues being detected on cold boot which is also causing waking from sleep bsod.

    Way to be punctual and terse about it! 🙂

    also i still dont get how firmware seems to boost the performance up for everything, its clear in CDM as well as ATTO or ADSSD, but not the vantage.. is it something to do with that issue with HDtune?

      This has us a bit stumped as well but, in testing as many SSDs as we have over the years, we have seen variances where SSD compatibility was an issue for on reason or another without a clear understanding of why.

        im wondering if its because the latency tripled as shown in the picture AS SSD and that probably cause the poor performance on the overall realworld vantage

    Is there any difference between 1.4RC and 1.4? (I’m wondering if they fixed the slow write speeds on the 2nd half of the disk.)

    Are there any considerations to running a pair of these in Raid0? The intent is performance. I saw a comment about 3 months ago that you were better off running the biggest ssd you could afford instead of 2 smaller in Raid0. Any truth to that?

    Raid 0 Setup with Vertex 4 (Firmware 1.5) 512GB SSD in HP Elitebook 8570W i7- Failed
    To potential OCZ SSD buyers,
    I posted the above matters to OCZ forum and got no solution from them after many email in and out in a week time. They want me to write an email to HP for help. They even deleted my reply and make the post like I did not reply their request or reply their mail. Furthermore, they blocked my post. They wanted me to send them a personal email instead of on the public forum.
    They moved my post to ForumOCZ Support ForumCompliments, Complaints, & SuggestionsVertex 4 512GB BSOD in RAID 0 setup.
    That’s why I totally agree with the post here on the first page:
    “It’s still a drive from OCZ, a company that has repeatedly and blatantly used its customer base as unpaid beta testers, and lambasted them when they dared to complain about it. No thank you. The fastest drive in the world is of no use to me if it’s causing my computer to BSOD constantly. I’ll be spending my money and that of my many clients on drives with proven track records for reliability and excellent customer service, both sadly lacking in OCZ products.”
    I will walk away from this OCZ unreliable SSD. Luckily I am able to return the drives and asked for refund instead of following their steps to do the beta tester in a week time.
    Think twice before you buy it.
    Thanks you.

    The OCZ SSDs got a lot of compatibilities and reliable issue. Just heading to their technical forum and you will know what I mean. The fastest drive in the world is of no use to me if it’s causing my computer to BSOD or other problem.
