Random Read/Write Speed

The four corners of SSD performance are as follows: random read, random write, sequential read and sequential write speed. Random accesses are generally small in size, while sequential accesses tend to be larger and thus we have the four Iometer tests we use in all of our reviews.

Our first test writes 4KB in a completely random pattern over an 8GB space of the drive to simulate the sort of random access that you'd see on an OS drive (even this is more stressful than a normal desktop user would see). I perform three concurrent IOs and run the test for 3 minutes. The results reported are in average MB/s over the entire time. We use both standard pseudo randomly generated data for each write as well as fully random data to show you both the maximum and minimum performance offered by SandForce based drives in these tests. The average performance of SF drives will likely be somewhere in between the two values for each drive you see in the graphs. For an understanding of why this matters, read our original SandForce article.

The SSD 730 isn't the fastest in peak performance because that's irrelevant in the enterprise space. We are still looking at decent random write performance and the random read performance is actually surprisingly good.

Sequential Read/Write Speed

To measure sequential performance I ran a 1 minute long 128KB sequential test over the entire span of the drive at a queue depth of 1. The results reported are in average MB/s over the entire test length.

The same goes for sequential performance: the 730 is an average performer with focus on consistency.

AS-SSD Incompressible Sequential Read/Write Performance

The AS-SSD sequential benchmark uses incompressible data for all of its transfers. The result is a pretty big reduction in sequential write speed on SandForce based controllers.

    I find it endearing. I bought a 240GB version of the 730 precisely because of its boring, but very practical features relating to reliability and early warning if there are any problems, not because of its speed (because that version is actually pretty slow in some areas). It seems so out of place that it kind of makes for a good story.

    Ever heard of their Extreme line of processors? Or Socket 2011 motherboards? Same deal. I think they also have the skull on their AIO liquid cooling kits (made for the Extreme processors). Just take it as a warning that nobody should buy it as it is overpriced compared to their normal goods.

    It's badaxe!

    Seriously. If I wanted a tasteless tattoo I'd go and spend the $10 on one.

    It was a joke for those that remember the D975XBX. I'm just mocking Intel's pathetic marketing attempts at being hard core.

    Is this WP 8 or 8.1? https://www.youtube.com/watch?v=ZMU51KeRIcs

    I think is bad ideal add on general customer product some religion symbol.. ok skull isnt religion symbol, but yes between us satanists are technology enthusiasts too :)

    I have to ask: What on Earth does a skull have to do with Satanism? It's just a skull with some stylized line art applied to it.
