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:

Light Workload 2011 - Average Data Rate

For lighter workloads that involve far less incompressible data, the 830 takes a clear backseat to the SF-2281 based drives. For nearly all users SandForce's real-time compression/dedupe architecture is a significant boon. You simply can't outperform a well designed controller that just writes less than the competition. The SSD 830 is at least significantly faster than the 470 and within striking distance (~10%) of the Intel SSD 510 and Crucial m4.

    Didn't read the article yet, but I sure did post the first comment. Looks like a fun read. Reply

    Do people seriously still do this? You think people would grow up and out of dumb habits eventually. Reply

    You'd think so, but GiantBomb even has an site achievement for getting first post (and not writing "first"). Reply

    But shouldn't it be okay if you post w/in the minute of it listing? Or, if it is published at some ungodly hour, like 4:39AM Reply

    But by replying, we made the useless thread longer....So did this comment, but lets try not to in the future ;)

    AT's comments do need some work though, edit button + downrank/hide option for comments like these would be miles improved by themselves.

    First posts should be auto-deleted when containing the word 'first' ;) Reply
