Samsung Unveils New 870 Evo Ssd With Faster Performance
Samsung has announced its newest SSD, a follow-up to the 970 Evo called the 980. The drive is a NVMe M.2 PCIe 3.0 drive, and it’s an affordable one, too. It costs up to $129.99 for the 1TB version and as little as $49.99 for the 250GB model. The T-Force Delta Max SSD from Team is about as stylish as a drive can get thanks to an RGB layer that can sync with a variety of motherboards. It’s actually on the fast side for a SATA SSD as too, and Team doesn’t charge too much for the gamer aesthetic.
But if you’re hoping a nice new drive will fix your slow copying problems, you’re probably out of luck—the 980 is neither worse nor better than other recent Samsung NVMe drives. The 970 Pro does not use an SLC cache at all and therefore doesn’t fall from the same “write cliff” that the 980 eventually does. In the longest-running test above—the 1MiB random write, which we ran using fiorather than CrystalDiskMark like the others—this gives the 970 Pro a chance to start running cleanly away from the 980 before the test ends. These 4KiB blocksize charts demonstrate the drives’ worst-case performance—reading or writing lots and lots of very tiny files. All tests in this chart are with 1MiB blocksize—this is performance similar to what you’d get reading or writing very large single files. In order to accelerate writes beyond that, you need a faster buffer area—which you can get simply by configuring part of your NAND as faster-moving, higher-endurance SLC.
The graphical Windows Disk Defagmenter in Windows 8.1 also recognizes SSDs distinctly from hard disk drives in a separate Media Type column. While Windows 7 supported automatic TRIM for internal SATA SSDs, Windows 8.1 and Windows 10 support manual TRIM (via an “Optimize” function in Disk Defragmenter) as well as automatic TRIM for SATA, NVMe and USB-attached SSDs. The operating system detects the presence of an SSD and optimizes operation accordingly. For SSD devices Windows disables SuperFetch and ReadyBoost, boot-time and application prefetching operations. Despite the initial statement by Steven Sinofsky before the release of Windows 7, however, defragmentation is not disabled, even though its behavior on SSDs differs.
Micron and Intel initially made faster SSDs by implementing data striping and interleaving in their architecture. This enabled the creation of ultra-fast SSDs with 250 MB/s effective read/write speeds with the SATA 3 Gbit/s interface in 2009. Two years later, SandForce continued to leverage this parallel flash connectivity, releasing consumer-grade SATA 6 Gbit/s SSD controllers which supported 500 MB/s read/write speeds. SandForce controllers compress the data before sending it to the flash memory.
However, the 3D NAND of the EVO 870 already belongs to the sixth generation and, according to Samsung, should offer at least 10% more performance than the EVO 860. Simultaneously, the energy efficiency increases gigabyte gtx 1060 3gb so that the power consumption is reduced by 15% compared to the EVO 860. If you want to know more about the different SSD storage technology types, we recommend the blog post Differences in SSDs.
It’s capable of hitting 7,000MB/s reads and 5,300MB/s writes in sequential transfers, which is well beyond the other drives’ capabilities. That’s because it uses the latest PCIe 4.0 interface, which has double the theoretical bandwidth limit of the other PCIe 3.0 drives. There is a more expensive version on offer with a heatsink attached to it. Still, so long as you don’t bury your drive in an M.2 slot beneath your GPU, you should be golden, and the SN750 will maintain peak performance without burning out and without any extra SSD cooling. Western Digital’s entry into the SSD arena was a long while coming, especially at the speedier end of the market, but the WD Black SN750 was worth the wait. It nails solid-state performance on par with the best consumer Samsung EVO SSDs and severely undercuts them on price.
However, to mitigate these performance bottlenecks, the DRAMless architecture uses host memory buffer tech that leverages the host system’s DRAM instead of an onboard DRAM chip to host the FTL mapping table. Samsung’s Magician application is one of the best pieces of storage management software available, and it’s getting better with its next iteration. Magician 6.3 comes with the same capabilities as prior gtx 1080 8gb versions but also brings the debut of Full Power Mode support. Like the WD Black’s SSD Dashboard Game Mode, this feature allows the 980 to operate at peak performance by disabling the lower power states, thus reducing the latency associated with transitioning between power states. Unforunately Magician 6.3 isn’t available for today’s review, but Samsung says it will be available within the next few weeks.
