his month, a few big names launched fast SSDs. The two most notable were Samsungs 850 Pro and SanDisks Extreme Pro. As you might expect, developments in NAND manufacturing play a central role in both products. The former employs 3D V-NAND. If you want to learn more about that (and what it means to performance), check out Samsung 850 Pro SSD Review: 3D Vertical NAND Hits Desktop Storage. Samsung has been working on this technology for years, and the Korean firm is gradually disclosing more information as it becomes relevant in new markets. While other vendors have designs not entirely dissimilar (from what information Ive heard), it’s unlikely we’ll see a solid-state drive using 3D NAND from other companies until late next year. SanDisks Extreme Pro picks up where last year’s Extreme II left off. It wields the same Marvell 88SS9187 controller used to great effect across the industry, but packs revised firmware and a substantial overclock to squeeze out more performance. SanDisk’s 1Y flash makes its debut as well. It’s similar to Toshiba’s A19 NAND, which cleverly repackages memory cells to reduce die size, ideally enabling higher yields.
