Hasta La Gadget!

When you head to Apple’s online store to configure your MacBook Air, you’ll find options to increase processor speed or SSD capacity — depending on the model you select, of course. There’s no mention of flash drive speed, however, though it’s now clear that not all SSDs are created equal at Apple — not only when it comes to capacity, but also performance. Jonathan over at TLD discovered a fairly significant discrepancy when benchmarking both MacBook Air models over the weekend. The 128GB Samsung SSD in his 11-inch Air was able to achieve 246 MB/s write and 264 MB/s read speeds. When he switched to the 13-inch model, however, speeds dropped to 156 MB/s and 208 MB/s, respectively, using that notebook’s 128GB Toshiba SSD. We compared speeds on two generations of 13-inch models, and confirmed Jonathan’s findings. During our tests, the 256GB Samsung drive in our older model achieved 214 MB/s write and 251 MB/s read speeds, while the 128GB Toshiba drive in the new MacBook Air scored 184 MB/s and 203 MB/s during write and read tests, respectively. Overall, you’re not likely to notice a significant difference during normal usage, though it’s certainly an interesting find, nonetheless.

Another season, another SSD roundup. This go ’round, its a six-pack of SATA III units — the speediest of the speedy — all angling for your hard-earned greenbacks. The benchmarking gurus over at Hot Hardware have assembled quite the guide for those currently in the market, hosting up a variety of top-tier drives from the likes of OCZ Technology, Patriot, Crucial and Corsair. We’ll leave the nitty-gritty for you to discover, but those hungry for spoilers will be elated to know that the SandForce-built OCZ Vertex 3 Max IOPS, Corsair Force GT and Patriot Wildfire proved to be the best performers in terms of transfer rates. That said, the whole lot managed to impress, and while the average user isn’t apt to feel the real-world differences among them, there’s a safe bet you aren’t in that “average” crowd. Cliff’s Notes? The Crucial M4 was deemed superior in terms of value, while the Vertex 3 Max IOPS and Wildfire just about tied for sheer speed.

Other World Computing may specialize in upgrading aging Macs, but you don’t have to own one to jam one of its new Mercury Electra 6G SSDs in your computer. The high-end SandForce Driven line of NAND drives range in size from 120GB to a far more impressive 480GB and, with the aide of 6Gb/sec SATA 3.0, can sustain write speeds of 523MB/sec and read speeds of 556MB/sec. Of course, this sort performance doesn’t come cheap — the smallest of the trio will set you back $230, while the massive 480GB model weighs in at a wallet-sapping $930. You can pick them up now from OWC if you’ve got a serious need for speed, and plenty of disposable income. Check out the PR after the break.

As file sizes for many data types continue to grow, smaller chunks are also becoming more ubiquitous, particularly on social media sites like Twitter and Facebook, and search tools like Google. These high-volume, small-size blocks of data may soon be served up from a specific type of SSD, like the Moneta Onyx prototype developed by a team at the University of California, San Diego. Onyx uses phase-change memory (PCM), which can rewrite single bits of data (1s and 0s) on demand, rather than rewriting data in larger chunks, yielding sustained 327 megabyte per second (MB/s) reads and 91MB/s writes with smaller file types — two to seven times faster than the most efficient commercial SSDs. PCM specifically benefits granular data, rather than large files that must be transferred completely (like photos and documents), so the tech is more likely to appear on devices serving up short text-based messages. Traditional SSDs can write larger files faster than the Onyx prototype, though the new drive offers speedier read speeds across the board. It’ll be at least a couple years before PCM becomes commercially available, but once (and if) it does, you’ll be reading about your coworker’s breakfast or college buddy’s traffic jam milliseconds faster than before.
