AnandTech Storage Bench - Light

Our Light storage test has relatively more sequential accesses and lower queue depths than The Destroyer or the Heavy test, and it's by far the shortest test overall. It's based largely on applications that aren't highly dependent on storage performance, so this is a test more of application launch times and file load times. This test can be seen as the sum of all the little delays in daily usage, but with the idle times trimmed to 25ms it takes less than half an hour to run. Details of the Light test can be found here. As with the ATSB Heavy test, this test is run with the drive both freshly erased and empty, and after filling the drive with sequential writes.

ATSB - Light (Data Rate)

The Crucial MX300 performs very well on the Light test with an average data rate that the MX500 cannot quite match, but the MX500 doesn't lose as much performance when the test is run on a full drive.

ATSB - Light (Average Latency)ATSB - Light (99th Percentile Latency)

The average and 99th percentile latency scores of the Crucial MX500 are largely unremarkable, though the 99th percentile latency is near the high end of the normal range. The MX500 is a substantial improvement over the MX300 when it comes to full-drive performance.

ATSB - Light (Average Read Latency)ATSB - Light (Average Write Latency)

The average read latency of the Crucial MX500 on the Light test is close to the Samsung 850 PRO and EVO when the test is run on an empty drive, but is merely average when the drives are full. The average write latency is a bit below average in both cases, but the full-drive penalty is much reduced compared to the MX300.

ATSB - Light (99th Percentile Read Latency)ATSB - Light (99th Percentile Write Latency)

As with the average read and write latency scores, the 99th percentile read and write scores fall within the normal range. The 99th percentile read latency is a bit better than average while the 99th percentile write latency is worse than most drives, but the MX500 isn't an outlier in either direction.

ATSB - Light (Power)

The power consumption of the MX500 ranks a bit better on the Light test than it did on the Heavy test. The Crucial MX300 is still substantially better, and the slow but DRAMless Toshiba TR200 holds on to a comfortable lead. The Samsung 850 PRO and EVO are in last place.

    The flyer I link shows the rated Sequential speeds and IOPS are the same for all capacities, so I wouldn't expect it to vary much Reply

    0 variation at all over all capacities strikes me as suspicious, not reassuring. Reply

    Oddly they note in the pdf that those numbers are:
    "Based on the published specs of the 1TB model. Speeds based on internal testing. Actual performance may vary"

    I think I finally found the drive to replace my aging mechanical drive in my venerable 2009 Macbook Pro. Reply

    Still going on that with an HDD? I'm still using the same model and an SSD sure perked it up. Reply

    Nice part. Look forward to seeing the 256 and 512MB results. Too bad the Crucial Storage Executive is still Java based. Reply

    The tool that you have to use what, a few times a year being Java based is some sort of problem? How? Reply

    Do you need it for anything but a FW update? I expect there'll be a few updates now in the beginning but I definitely wouldn't call it a problem. Reply

    I think I've updated firmware on my Crucial drives, but I know I don't have Java on any of those systems. Reply

    Java comes with the dashboard installer. Reply
