SSD Showdown: 4 Top Drives Reviewed
Post-Race Wrap-Up
Team SandForce maintains dominance in a field of strong performers
We’ve been anxiously awaiting the SF-2200 controller for a while—could the company that sprung out of stealth mode to take the solid-state drive market by storm in 2010 pull a repeat in 2011? Though we’re still a few months away from seeing multiple vendors shipping SF-2200 drives, if the performance of the OCZ Vertex 3 is any indication, it’s going to be another good year for SandForce.
The SandForce-powered OCZ Vertex 3 is the clear winner of our little roundup, posting race-winning scores in virtually every benchmark. In CrystalDiskMark and AS SSD, which are solid-state-specific synthetic benchmarks, the Vertex 3 posted average sequential reads of 500MB/s and average writes of 280MB/s, second only to the Intel 510. In queue-depth 32 4KB random-read and -write benchmarks (both Crystal-DiskMark and Iometer), the Vertex 3 again bested the rest of the field, though Crucial’s m4 SSD came within spitting distance of OCZ’s drive. PCMark Vantage, which mirrors real-world applications, actually gives the top spot to Crucial’s m4 SSD, with the Vertex 3 a close second.
One interesting result our testing shows is the importance of good firmware. Three of the drives in our roundup share the same Marvell 9174 controller (albeit with varying amounts of cache), but they all post different benchmark results. Intel’s 510 shows the strongest sequential-read and -write scores by far, but its random-access scores are no better than those of the Plextor M2. Crucial’s m4, on the other hand, shows random-read and -write speeds almost as high as the Vertex 3, but its sequential speeds were much lower than the Intel or OCZ drives. Intel’s and Crucial’s offerings each excel in at least one area, while the Plextor M2 is competent compared to last-gen drives but unexceptional compared to this generation.
We should make explicit that any of these solid-state drives deserves your purchasing consideration. They’re all powerful performers that really take advantage of the increased bandwidth of the 6Gb/s SATA bus. Depending on your needs, either Crucial’s or Intel’s drives should be near the top of your list, though the OCZ Vertex 3 combines the best features of each—for a price.
