Although SandForce controllers have powered much of OCZ's solid-state lineup, the company is shifting to its own solutions after purchasing Indilinx early last year. The "Octane" flash drives were the first to use the Indilinx Everest controller last holiday season and now that its SF-2281-based drives are over a year old, OCZ has begun phasing Everest into the rest of its offerings, including the Vertex series.
Since the Octane's launch, OCZ has whipped up a second-gen Everest controller, the silicon behind the company's new Vertex 4. Despite touting more performance than the Octane series, the Vertex 4 appears to be competitively priced with existing SandForce, Samsung, and Marvell-based drives, which should make it a more viable option -- if not the de facto choice -- among high-end system builders...
The RealSSD C400 represents a mild performance gain over last year's C300 during light workloads, it's handily dispatched by competing drives from OCZ and Intel when it comes to heavy multitasking, but that's okay if the C400's price reflects its inferior performance and it does -- there's nothing wrong with delivering an entry-level product.
The OCZ Vertex 4 Series 64GB model packs read and write speeds of 460MB/s and 220MB/s. The 128GB version is much faster with 550MB/s reads and 420MB/s writes. The 256GB and 512GB models feature the same 550MB/s reads, but writes are boosted to 465MB/s and 475MB/s, respectively.
The Intel SSD 520 Series is aimed at performance buffs with initial SF-2281-based models offering capacities of 60GB, 120GB, 180GB, 240GB and 480GB. It also has a slim design, measuring 100 x 69.85 x 9.5mm and weighing up to 78 grams. The 60GB model packs read and write speeds of 550MB/s - 475MB/s, while the larger 120GB version provides 550MB/s reads and 500MB/s writes. The 180GB, 240GB and 480GB models are slightly faster again as the write performance is boosted to 520MB/s. Naturally, using the SATA 6Gb/s interface is essential to achieving those speeds.
The Samsung SSD 470 features a 250MB/s read and 220MB/s write performance. It uses a flash NAND memory that utilizes 30-nanometer technology and in total there are 16 chips with each IC having a 16GB density. The Samsung 470 Series drives measure 100 x 69.85 x 9.50mm and weigh just 68 grams, thanks to their slim 2.5" design they are ideal for both desktop and laptop computers.
