Samsung SSD 840 Pro caters to speed seekers with faster random access
It’s difficult to thrive in the solid-state drive world. Unless you’ve got just the right controller and flash memory, most performance-minded PC users will rarely give you a second glance. Samsung muscled its way into that narrow view with the SSD 830 last year; it intends to lock our attention with the new SSD 840 and SSD 840 Pro. The Pro’s 520MB/s and 450MB/s sequential read and write speeds are only modest bumps over the 830, but they don’t tell the whole story of just how fast it gets. The upgraded MDX controller boosts the random read access to a nicely rounded 100,000IOPS, and random writes have more than doubled to 78,000IOPS or 90,000IOPS, depending on who you ask and what drive you use. The improved performance in either direction is a useful boost to on-the-ground performance, as both AnandTech and Storage Review will tell you. We’re waiting on details of the ordinary triple level cell-based 840 model beyond its 120GB, 250GB and 500GB capacities, although there won’t be an enormous premium for the multi-level cell 840 Pro over existing drives when it arrives in mid-October — the flagship line should start at $100 for a basic 64GB drive, and peak at $600 for the ultimate 512GB version.
Intel SSD 520 review roundup: Intel reliability, SandForce speeds starting at $149
There’s plenty of SSD options out there, but Intel’s NAND drives are among the most well thought of, simply because they’re so reliable. But, with the top speed of competing SSDs spiraling higher, Intel’s rock-solid reputation may not be enough for some enthusiasts. Enter the SSD 520, with a performance SandForce SF-2281 controller and custom firmware (codenamed Cherryville) on board to ensure the 520 meets Chipzilla’s demanding standards for stability. It’s the result of a year and a half long collaboration between Intel and SandForce, and is available in both 7mm and 9.5mm thin form factors to fit any machine — Ultrabook or otherwise. Aside from the SandForce chip, the 520 packs Intel’s finest 25nm NAND Flash, a SATA 6GB/s connection and its 550MB/s reads and 520MB/s writes can be had for $149 in 60GB garb and prices escalate up to a grand for 480GB. Naturally, as this is Intel’s effort to snatch back the performance market, a raft of reviews have been written about the SSD 520.
So, how does the 520 stack up? Well, Intel’s so confident in the 520 that it’s backed the SSD with a five-year warranty. Though its performance doesn’t drastically outpace its competition, Storage Review found the drive to be on par with the current speed king, OCZ’s Vertex 3 in its benchmarks — and also found performance and stability to be quite good in both enterprise use and in RAID arrays. Meanwhile, AnandTech found that the 520′s peak random write speeds quite similar to its sequential reads during testing, which shows how well the optimized firmware works with the NAND. Hot Hardware thought the 520 to be comparable to other SandForce-equipped SSDs, but in terms of power consumption, Tom’s Hardwarefound Intel’s latest to be a power hog. Generally, all the reviewers were in agreement: the 520 is a speedy SSD, but you pay a hefty premium for Intel’s reputation for churning out reliable drives. Only time will tell if the 520 can deliver the reliability we want, but there’s plenty of performance info to be had in the reviews listed below.
