OCZ AMD Radeon R7 SSD Review (240GB)


ATTO Disk Benchmark is perhaps one of the oldest benchmarks going and is definitely the main staple for manufacturer performance specifications. ATTO uses RAW or compressible data and, for our benchmarks, we use a set length of 256mb and test both the read and write performance of various transfer sizes ranging from 0.5 to 8192kb. Manufacturers prefer this method of testing as it deals with raw (compressible) data rather than random (includes incompressible data) which, although more realistic, results in lower performance results.


Although we easily reach listed specifications with 555MB/s read and 532MB/s write, the transfer speeds don’t quite graduate with file size as we might like to see.  This doesn’t necessarily mean there is anything wrong with the drive at all, but we tested a few times and still only returned 40MB/s for 4K read speeds.


Crystal Disk Benchmark is used to measure read and write performance through sampling of highly compressible data (oFill/1Fill), or random data which is, for the most part, incompressible. Performance is virtually identical, regardless of data sample so we have included only that using random data samples.

Crystal DiskMark displays solid performance for the AMD Radeon R7 SSD, especially when we look at the low 4K random write performance of 155MB/s.


The toughest benchmark available for solid state drives is AS SSD as it relies solely on incompressible data samples when testing performance.  For the most part, AS SSD tests can be considered the ‘worst case scenario’ in obtaining data transfer speeds and many enthusiasts like AS SSD for their needs. Transfer speeds are displayed on the left with IOPS results on the right.

An ISO score of 415MB/s is great but we would have like to see the other two results to jump a bit. AS SSD Copy Bench is a true to life program where ISO, program and Game files are moved from one spot on the SSD to another, monitoring the top transfer speed and time it takes to move each file.


  1. Go AMD! Good one Les! Looks like a very good SSD.

  2. Cheers Les – I’ve been looking forward to this review for a while – also linked it at http://www.gamingtribe.com/status/13194139584347/?v=d155c8c3963c661791f1a3fca3e5105d for the gaming community at GT

    I’m willing to forget all my former bad experiences with them and try this drive or the Vector 150, the only thing that’s holding me back is their over-crowded pcb! not sure why OCZ/Toshiba pcb’s look like SAS/Data center drives!

    • And thats bad how ?
      Smaller pcb means lower cost.

      • Z Inter fan - Kuwait

        I’m not talking about the size, what worries me is the amount of capacitors/items that populate their drives.

      • Care to explain ?

      • Z Inter fan - Kuwait

        The more items you have.. the more could go wrong.
        Other manufacturers have far cleaner/less populated pcbs.

      • While i see your point, lots of SSDs have design like that and never caused trouble. Those are pretty dumb components and wont die easily. The controller is the main problem with ssds, when it comes to reliability.

      • Z Inter fan - Kuwait

        You’re right my friend.. It’s just that I’m questioning the purpose of these components and nothing more.

      • I wonder the same. For all its worth, they could get away with a much smaller PCB and only 2-4 packages aswell (by using 8 dies per package). That would save cost, which could translate to lower MSRP.

        Big guys are doing this for a while now (samsung and smi based drives to name a few).

      • Z Inter fan - Kuwait

        I’m with you in this, a cleaner/smaller pcb would most likley lead to better cost saving.

      • sounds like you don’t understand PCBs. It doesn’t matter if the components are “visible” or not. In fact there’s going to be more heat if more of the components are inside an IC rather than on the outside. If you really don’t want to see the components, you basically have to remove them all together, e.g. downgrade the card.

      • Z Inter fan - Kuwait

        Hello Eisa,
        That still does not change the fact that all other bigger, more established manufacturers are making far more cleaner pcbs.

      • Sorry, but this is a really stupid complaint. If they were electrolytic capacitors then at least we could talk about it, because those had limited life-expectancy if they are highly loaded. But these are solid capacitors. You should complain if they do not put enough capacitors into a product. Yes, that is a usual cost reduction method. These are basically noise filtering capacitors. Without them the product is cheaper but less reliable.

  4. PR article at best, does not stand out in any way, I’d still take sammy or crucial mx100 over this any day, bf controller is the best my ass.

  5. I used to frequent this site for reviews, but if you can’t even take a honest critique of the artile (PR stuff otherwise), don’t even bother. And thank for deleting my previous post, looks like it was too much to handle, right?

  6. I enjoyed your review but as of now, nearly two weeks later, they are not yet in stock with Amazon. “Order now and we’ll deliver when available.”

    Do you have any updates on availability?
