Plextor M5S 256 GB Review: Marvell Inside, With A Twist

Benchmark Results: Iometer

Our Iometer benchmarks are run using an 8 GiB LBA range on the logical disk with a 90 second run time, using 4 KiB sector boundaries.

The following graphs reflect read and write performance for common transfer sizes at queue depths ranging from one to 32. In a typical client environment, queue depths are generally pretty low. So, the performance figures with queue depths between one and four are particularly interesting.

When it comes to random reads, Plextor's M5S comes out on top for all transfer sizes at queue depths in our most relevant range, except for the 64 KiB transfer size. Samsung's 830 sneaks ahead of the M5S there, but only at queue depths of four and higher.

There's a lot more variability in our random write results. Fine-tuned firmware serves Crucial's m4 well during the 4 and 8 KiB transfer sizes at low queue depths. But, as the transfer sizes start to increase, performance becomes less impressive and the m4 ends up at the bottom of the charts.

    Why in your reviews you dont mention anything about FDE and its support in modern mainboards based on chipsets for Ivy Bridge? It is much more crucial feature to some people than small differences in performance.

    I'd be more worried about matching Mushkin's price / performance ... and same 3 year warranty.

    Samsung 230 - $227 ($0.89 / GB)

    Mushkin Chronos Deluxe - $180 ($0.75 / GB)

    Good I hope the market continues to get flooded with SSD's the recent price drops are no doubt hugely influenced by competition.

    Hate to break it to you buddy but the Mushkin link leads to a 128GB for $179.99 That is well above $1 per GB.

    I wonder if the Plextor cloning software is as good as their Hdd's?

    He gave the wrong link and mistook the Delux for the non-Delux. The above link is the non-Delux 256GB for $179.99. The Delux is another $10 at $190:

    Still, I'd go with the Vertex 4 256GB at $190 instead of any of these at their prices.

    A small inexpensive (25 cent) capacitor could provide enough power to complete writing what remained in the dram if it is a major problem.
