AnandTech Storage Bench 2011 - Light Workload

Our new light workload actually has more write operations than read operations. The split is as follows: 372,630 reads and 459,709 writes. The relatively close read/write ratio does better mimic a typical light workload (although even lighter workloads would be far more read centric).

The I/O breakdown is similar to the heavy workload at small IOs, however you'll notice that there are far fewer large IO transfers:

    "And in 95% of all I/O operations are random I/O."

    You're either an idiot, a liar or both. I'll take Anands' word and common techy sense over yours.

    I think it'd be useful if you added a "standard" hard drive to the power graphs, just so people can more easily see whether it consumes less power than an old platter drive.
    Also, have you put any thought to putting up a table that lists the total energy used to complete your benchmarks? I've seen that some of the faster drives draw more power, but wouldn't it sometimes work out that it still uses less energy since it completes the test faster?

    I would honestly love to see desktop motherboards have a port for these on board, and have the form become common enough that you could just snap one on and eliminate the cables associated with it. SFF PCs could become single board affairs with cabling only for power and an optional optical drive.

    Now imagine this attached to a modified Rasberry Pi. Ultra small computer, with storage to boot. And all powered by USB. That will be the day. And to push the envelope further, display using the Google's Project Glass. ULTIMATE!!

    Power's still a little high to go from USB; USB can deliver 4.5W, while this drive takes up to 4W while writing. That only leaves 0.5W for the rest of the mini-puter.

    So what exactly does a 36TBW mean, in useful terms?

    As in, if the drive is used for the primary OS install, then how long will it typically take to accumulate 36 TB of writes, and what happens when that number is reached? Compared to other drives of similar capacity, is 36TBW good, middling, or poor? Is there any empirical data showing a correlation between SSD longevity and "Endurance Spec"? If so, what is it?

    What was the drive hooked up to for this test? I would appreciate more upfront methodology recaps in these reviews.

    I am also curious as to whether the mSATA ports on motherboards (for example the upcoming Gigabyte Z77 ones) are 3 Gbps or 6 Gbps ports...

    Wake me up when you decide to do a real world test. You know, the time it takes to do something, like boot up or load a program. That's more meaningful than any synthetic benchmark.

    You clearly have not been reading this site for very long and don't understand much about SSD performance.

    Anandtech used to include those exact benchmarks and they became pointless because in those types of tests the performance across SSDs is nearly the same. I suggest educating yourself before opening your mouth and looking like a luddite.
  • AnnonymousCoward - Wednesday, April 11, 2012 - link

    What a foolish response. You're wrong because I have been reading the site for a long time, including the first SSD articles.

    Your own words validate my point! If *actual* performance is nearly the same, that's what we want to know!! It's stupid to only look at meaningless graphs that show alleged large differences.

    The real performance difference is all that matters. And if that's very small, then we know to buy based on price and reliability!
