Marvell 88SS9174-BLD2 SSD Processor
Crucial m4 Solid State Drive
Marvell 88SS9174 Performance

AS-SSD Benchmark

Beginning with sequential read and write performance, the 256GB Crucial m4 SSD CT256M4SSD2 produced 402.21 MB/s read speed, and 263.46 MB/s write performance. This compares well against the new SandForce SF-2281 controller on the OCZ Vertex 3, which produced 505.67 MB/s read speed, and 282.84 MB/s write performance

Single-threaded 4K IOPS performance delivers 19.73 MB/s read and 57.70 MB/s write, nearly matching the OCZ Vertex 3 with 21.69 MB/s read and 61.58 MB/s write. The 64-thread 4K reads recorded 158.24 MB/s and 211.48 MB/s writes, compared to 164.88 MB/s and 221.39 MB/s for the OCZ Vertex 3.

ATTO Disk Benchmark

Our basic bandwidth speed tests begin with the Crucial m4 SSD attached to the Intel SATA 6Gb/s controller operating in AHCI mode. Using the ATTO Disk Benchmark tool, the test drive performs file transfers ranging from 0.5 KB to 8192 KB. The CT256M4SSD2 model we received reveals 446 MB/s maximum read speed that plateaus from 128-8192 KB file chunks, and 281 MB/s peak write bandwidth plateaus from 8-8192 KB. These both exceed Marvell specification, and meet manufacturer specification.

CrystalDiskMark 3.0 Tests

Each of our tests with the Crucial m4 SSD were consistent, and the best results obtained were used in the chart below. Sequential tests on this Marvell solid state drive produced a maximum read speed of 410.0 MB/s while the write speed was 277.0 MB/s, compared to 500.6 and 300.5 MB/s for the OCZ Vertex 3.

CrystalDiskMark 3.0 reported 512K results of 329.9 MB/s read and 276.9 MB/s write performance, which compares to 440.0 MB/s read and 295.6 MB/s write for the SandForce SF-2281 SSD. 4K tests produced 21.68 MB/s read and 68.94 write performance, while the OCZ Vertex 3 produced 33.33 MB/s reads and 80.11 writes.

Based on our tests, it seems that performance emphasis has switched read and write priority when compared to the previous RealSSD C300 series. The new Crucial m4 SSD stands strong all on its own, but it's too soon to tell how well these minor tweaks appeal to consumers. Compared head-to-head, SandForce 2200 SSDs appear to offer better performance than Marvell 88SS9174 revisions, which could make it difficult for the Crucial m4/Micron RealSSD C400, as well as Strontium SSD Matrix, Intel SSD 510, Corsair Performance 3, and others to thrive.

For the Crucial m4 SSD to succeed it must be aggressively priced against the competition, but the five-year warranty certainly sweetens the deal. The complete Crucial m4 Solid State Drive review is goes into more detail on these points. Micron officially launched the Crucial m4 SSD on 26 April 2011, offering the following capacities: 64GB Model $150, 128GB Model $260, 256GB Model $520, 512GB Model $1000.
