AnandTech Storage Bench - Heavy

Our Heavy storage benchmark is proportionally more write-heavy than The Destroyer, but much shorter overall. The total writes in the Heavy test aren't enough to fill the drive, so performance never drops down to steady state. This test is far more representative of a power user's day to day usage, and is heavily influenced by the drive's peak performance. The Heavy workload test details can be found here. This test is run twice, once on a freshly erased drive and once after filling the drive with sequential writes.

ATSB - Heavy (Data Rate)

The Plextor M8V has a slower average data rate on the Heavy test than most mainstream SATA SSDs, but it retains almost all of that performance when the test is run on a full drive. This gives it a clear advantage over last-generation drives like the Crucial MX300 and ADATA SU800 that have higher peak performance but don't hold up well under pressure.

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

The average and 99th percentile latencies of the Plextor M8V on the Heavy test are higher than for any of its current-generation competitors, but the M8V isn't one of the huge outliers.

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

Both the average read latency and average write latency scores from the M8V are slightly higher than normal for mainstream SATA drives, but the differences aren't big enough to worry about.

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

The 99th percentile read latency of the M8V is unusually poor, matching the Plextor S2C and substantially exceeding all the competitors, even the Toshiba TR200. The 99th percentile write latency is not an extreme outlier, merely a bit higher than what the top-tier SATA drives provide.

ATSB - Heavy (Power)

The energy usage by the Plextor M8V on the Heavy test is clearly higher than most SATA drives, but by a fairly small margin.

    What's the actual capacity of this drive, 476 GiB? I hate having to use a calculator/guessing. Reply

    As with any other 512GB drive, the usable capacity (before partitioning) is 512,110,190,592 bytes. Reply

    Crucial MX200 500GB ends up as 465gb usable Win 7 64 build after formatted for use
    Crucial MX100 256 ends up with 238GB usable

    That would be because Windows displays GiB (2^30 bytes) and not GB (10^9 Bytes).

    During formatting, some space is reserved for the file system. That is not a limitation of the drive, nor does it make the drive have a smaller capacity.
    You don't like file system's overhead? Use a different file system. Oh wait, you can't do that on Windows :D
