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:

    Amazing. I am using an OCZ Vertex4 256GB drive. Bought it last Nov for about $224. Very happy with it.
    This SanDisk drive is the same price ($229), same capacity (240GB), same format. However, it is performing a full 5% to almost 100% better, depending on block size, random/sequential, read/write activity. Amazing what 7 to 12 months has brought to the SSD market!

    In fact this is not what your test does. Your test records IOPS in one-second periods, but does not measure the latency of individual IOs. It would in fact be interesting to see the latency distribution for these drives.

    Ive done som IO Latency tests based on my own trace-based benchmark if your interested.

    The text is in swedish, but you should be able to understand the graphs. I could make aplot diagram of individual IOs Latency if anyone is interested,

    I still have an indilinx 64GB. Reply

    Is it just me or have the SSD prices stagnated since the past year or so? I bought a 120GB Plextor M5S for $85 in July 2012 and the 128 GB SSDs still seem to hover in the 100-120$ range. Reply

    Hey Anand , can you please test 6 SSD Raid 0 with the new Haswell Z87 motherboards ?

    we need to make sure we can hit 3G/s , what is the maximum bandwidth of the new chipset ?

    This looks awesome, it's almost neck-to-neck to the 840 Pro, at a lower price. Reply

    Hi Anand,
    Do you plan on covering the OCZ Vertex 450?

    All tests have been run but I guess Haswell and other Computex stuff got on the way. Reply
