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:

Performance in our Light suite is fairly similar to Heavy suite: The Mercury Electra isn't unbelievably fast but it does okay for a SATA 3Gbps drive.

    I sort of get it, this thing is kind of affordable but in a year, with next gen Nand available128Gb/16GB), all prices will continue to crash($/gb). And high storage nand in 2.5" form factor is not all that unique. OCZ has had a 1tb drive out since at least may (OCT1-25SAT3-1T), which can be found on newegg or amazon. When you are already spending more than a grand for a drive, might as well grab one that is at least 6 Gbps compatible.

    Either drive will depreciate faster than is acceptable for me. I am still waiting for a $130 fire sale on an Vertez 4 256gb though, right now I have a poor mans raid 0 of a 128gb vertex 4 and a 120gb Agility 3, both of which I paid $140 plus for awhile ago. Its just as bad as when I spent $100 for 4gb of DDR3 3yrs ago. Buyers remorse, the cost of adopting tech early.

    If this thing is for Audio and Video Professionals, then it's more than likely targeted for Mac users. Mac users are well known for overpaying for their hardware, so the price for this piece of steaming pile is fitting.

    You really need to fix your chart making when performance is very low.
    If the performance number doesn't fit the bar, move it next to it instead of overlapping with the product name.
    I commented on this years ago but nothing's happened. We don't often see the bars go so low, but sometimes they do.

    Our CMS makes the graphs automatically so I can't play with small details like where the actual number is placed. I'll pass a word to Anand and see if there is a way to fix it, because I find that irritating as well.

    Actually, there is a way to do this Kristian: check the "outer labels" box at the top-right of the graph. I've fixed the two random write charts and regenerated.

    Thanks, hopefully all of you remember to do this when necessary (looks like it requires manual work).

    For consistency between different charts, you should either make this the default, or change it so it only places them outside for too small values. Maybe even for all values below 50% of the largest.

    I don't buy that they couldn't afford to put a SATA6G connection on there. The price is already through the roof and newer SSD's hit way past the normal limits of SATA3G (some even bump up against the SATA6G limit).

    OWC didn't exactly specify why they had to stick with SATA 3Gbps, they only said it was a combination of things including price, thermals and space. I wouldn't be surprised if there simply was no SATA 6Gbps controller as the market for such controllers is fairly small. I know Silicon Image doesn't have one, at least.

    I have a Macbook with an HDD + SSD in an optical bay adapter, but I'd sooner duct tape an external drive to the back of the lid that overspend on something like this.

    Hell, I'd rather install a pair of WD Blacks and software RAID them.

    Audio doesn't need as much sequential I/O as video, though, I guess.

    Somebody will buy it though.

    What if they used JBOD or linear raid rather than raid0?
