Crucial M4 Adrenaline 50GB Cache SSD Review – Watch Your Hard Drive Perform Like an SSD


This is The SSD Review Test Bench Number One. A quick click on the photo will give you a better look.

In testing, our main objective is to obtain results as pure and as accurate as possible and we want to ensure that no anomalies slip through. Simply put, we want to provide you with the absolute best results the tested hardware can provide. Repetition in testing is standard and, if necessary, we may conduct specific tests in Windows 7 ‘safe mode’ to ensure the OS has little to no influence on the end result.

In order to validate and confirm our findings, testing is supported by industry accepted benchmark programs. All results are displayed through capture of the actual benchmark for better understanding of the testing process by the reader.

blankWe would like to thank Gigabyte, Corsair, MSI, OCZ, and Fractal-Design, for sponsoring components of our Test Bench.


For todays testing, we will be using ATTO Disk Benchmark, Crystal DiskMark, Anvil Storage Utilities, PCMark Vantage and we are even going to do some comparative testing in start times. In order to assist, we have supplied links in the titles of some of our favorite analysis software to encourage testing of your own as well.

On the following pages, the test format will simply compare the original HDD score performance to that of the same HDD when cached with the Crucial Adrenaline.  In the next few tests below, however, we have tested the Crucial Adrenaline without the NVELO Dataplex installed in order to give you an idea how this SSD would function if it were to be used as an SSD and not HDD caching solution.


The results of ATTO Disk Benchmark are very close to listed specifications and we see that the read result of 554MB/s brings us well into the SATA 3 zone.


blankMany may think that the write performance of 114MB/s might seem a bit low but it falls in line with the performance of an M4 of this capacity.  The purpose of the Adenaline is to boost the start time and typical user experience significantly.

    I find it funny how you say this is the game changer where the OCZ Synapse has been out for quite some time now.

    I was looking forward to a comparison between this to the OCZ Synapse, It would be nice to have a comparison review on them, such that I can know as well the performance differences on a similar system.

    • blank

      Did I say game changer? There is no comparison to the Synapse, or even the new Crucial for that matter, simply because the software (Dataplex) used in all is exactly the same and simply amplifies the hard drive speed to that of the SSD being used. If you want to run a comparison of both, simply examine both reviews. We choose not to do the comparison because the main point of interest is the caching solution and its effectiveness on the system in this case.

      Having said that, we could have probably run a caching comparison but I feel we are then taking away from the focus on what we tried to put forward which is the effectiveness and simplicity in implementing the caching solution.

      Thanks for your comment and maybe we will run a head to head once a few more hit the streets.

        Could you make a comparison with srt using the same drive?

      • blank

        I don’t use SRT as there is no comparison. Dataplex simply changes the performance of the hard drive to that of the SSD in use, something that SRT has yet to match. Tx for taking the time to comment.

        Also, if you like, i can upload my results with testing SRT, which, i have been using since z68 boards dropped, i have yet to see anything similar “match” IT!

        I didn’t mean to upset you and only expressed my opinion and experience. Nice to have you jump in though.

        Hi there Mr. Tokar. I’d like to thank you for two things, and I also have a question. One, thank you for all the reviews you’ve done, knowledge is power and this site has helped me tremendously with SSDs. Second, thanks for writing about your subjective experience with SRT. I have seen benchmark comparisons in the past but never had someone explain that Dataplex works better than SRT in the real world.

        And my question is, if I have a caching SSD such as the Synapse or the Adrenaline, should I do the SSD optimizations? I’m talking about the articles that you guys have in the ‘beginner’ section that tell you to change Windows 7 settings for your SSD.

        Thank you and take care.

      • blank

        I am going to suggest not to do the SSD optimizations as the background of these was made through use of a primary recognizable drive, unlike the Adrenaline and other cached designs. Remember, your primary drive is still a hard drive, although it is cached.

    wow that is some great improvement from such a small ssd, tbh i am really surprised at how well that works 🙂

    Does the cache work for the entire hard disk or only the partition?

    • blank

      The cache is et for the drive that it is identified, regardless of the number of partitions on the drive.

      • blank

        Thanks. That’s a decent deal, then. I usually have quite a few partitions on the disk and won’t want to have only one of them cached.

        BTW, does this solution work with disk partitioning tools? If I change the size of a partition using such a tool, would it kill everything or work as if there was nothing behind the curtains.

    Hello Les, may I ask you a favour? I only want to know if in SATA 2 it would be approximately the same boot time (slower it’s sure but how), because still now the majority of people are using SATA 2 in their computers and this solution could be very attractive for older computers.

    • blank

      You will not observe a difference in the boot time as it is disk access which is instrumental in your boot time, regardless of whether it is SATA 2 or SATA 3.

      Actually, I was shocked as heck to get such a quick boot time in these tests.

    @Les@TheSSDReview “Dataplex simply changes the performance of the hard drive to that of the SSD in use, something that SRT has yet to match.”……………………….WOW, so, without using SRT, you say that it can’t match this setup? well, you are in fact correct, SRT surpasses this technique, using a Mushkin Chronos Deluxe 60GB SSD to push a WD 500GB HDD, it scores 1,513.34 read-1,990.00 write=3,503.34 total using the Anvil Storage Benchmark, and, when using the 120GB Chronos Deluxe, it is even better, you should bench SRT before bashing it, Peace!

    I am not upset, just thought that i would enlighten you so that people will take this sites benchmarks seriously, that’s all.

    Les, I wish you’d started out your review by saying this only works with Win 7. I’m a Mac guy and was really disappointed to find it’s not available for the Mac. Also, reading the Amazon reviews, they are pretty much 5 or 1 star. The one stars are from those whose computers weren’t compatible and their HDs were trashed. Nvelo seem to be fixing the problems but it will probably be a while before all the bugs are out. The advice, as always, is to back up your whole system (clone it) so you can be up and running quickly if you are one of the unlucky ones.

    Also, I want to thank for all the info and reviews here. Based on your review I bought an Intel 520/240GB SSD for my MacBook Pro and couldn’t be happier.

    I also have to ask, what is all this rebooting about? Five times per day average?! As a Mac guy, I’ve gone weeks without rebooting.
