Samsung has announced an update to its well-received 830 SSD series of yesteryear. The predictably named Samsung 840 SSDs come in two flavors: a consumer-grade model that retains the 840 moniker, and a model tuned for professionals called the 840 Pro.
We are all by now familiar with the advantages of solid state storage over traditional hard disk drives. Skipping any hyperbolic (but mostly true) claims to fame, we can compare the performance gains of the 840 Pro relative to Samsung's previous flagship, the 830 SSD.
Random read speeds for the 512GB 840 Pro are up 25% to 100,000 IOPS, while random write speeds have doubled to 90,000 IOPS. The more impressive gains have been made in power demand. When idling, the 840 Pro draws 0.042 watts, and that number increases to 0.068 watts when the SSD is humming. The 840 Pro also has specialized firmware that tunes the drive for omtimum performance under heavy (think IT and server class) workloads. Both lines of the 840 will use a six Gb/s SATA connector. The 840 Pro will come in 64GB, 128GB, 256GB and 512GB flavors. Pricing for each will be $99.99, $149.99, $269.99, and $599.99, respectively.
The 840 carries the torch for the less demanding consumer. Specs aren't far behind the 840 Pro. Random read speeds are at 98,000 IOPS, while random write speeds clock in at 70,000 IOPS. This SSD is tuned for gamers and comes in the more standardized sizes of 120GB, 250GB and 500GB. Prices here are $109.99, $199.99, and $499.99. Each of these capacities also comes bundled with a bracket and cabling for a $20 price premium.
Samsung is heavily touting its control of the manufacturing process from start to finish, using only in-house parts. The 840 series is an all-Samsung product in an increasingly commoditized consumer electronics market. The benefits of vertical integration in the manufacturing process show when looking at Samsung's strong reputation for reliability in the SSD market. The Korean company backs the 840 Pro with a five year warranty. For the standard 840, you still get three years of warranty protection, likely long outlasting the warranty that came with the laptop the SSD will be situated in.
