The big picture: Samsung's new 970 EVO Plus is getting close to reaching the theoretical limits of the PCIe 3.0 M.2 interface. It's a nice feather in Samsung's cap but arguably an even more impressive feat for SSDs as a category, especially when you consider where the technology was just a decade ago.

Samsung on Tuesday its latest NVMe-based solid state drive, the. It’s built on the M.2 (2280) form factor and uses the latest fifth-generation V-NAND technology with optimized firmware to push performance to new heights. The new drive delivers sequential read and write speeds of up to 3,500 MB/s and 3,300 MB/s, respectively, besting the standard 970 EVO’s 3,500 MB/s / 2,500 MB/s capabilities.

Random read and write speeds (QD32), meanwhile, check in at an impressive 620,000 IOPS and 560,000 IOPS, respectively. Again, last year’s model was rated at 500,000 IOPS read and 480,000 IOPS write.

Samsung’s latest carries a five-year limited warranty or up to 1,200 terabytes written, whichever comes first. In its review said the 970 EVO Plus is “pretty much as good as it gets” while showed an improvement – sometimes huge – over the original 970 EVO. The 970 EVO Plus is offered in capacities of 250GB, 500GB and 1TB with MSRPs of $89.99, $129.99 and $249.99, respectively.

Samsung says they’re available to purchase from today although I’ve had no luck finding them as of writing. A 2TB drive is also on the way in April, we’re told, at an unspecified MSRP. Thumbnail courtesy PCGamesN Related Reads • • • •.

At Samsung's Tech Day event today in San Jose, the company shared their SSD roadmap for transitioning to 96-layer 3D NAND and introducing four bit per cell (QLC) NAND flash memory. Successors have been named for most of their current SSDs that use three bit per cell (TLC) NAND flash and are being updated with 96-layer 3D TLC, and new product lines using QLC NAND have been introduced. Taking TLC to new heights Most of the updates to the TLC-based SSDs are fairly straightforward NAND upgrades that use existing SSD controllers.

The PM981 client NVMe SSD and the 970 EVO retail counterpart that use 64-layer 3D TLC will be succeeded by the PM981a and 970 EVO Plus respectively. Capacity options remain the same, ranging from 250GB to 2TB.

The most significant performance improvements are to sequential write speeds, but the PM981a also brings significant random I/O improvements that almost catch it up to the 970 EVO and 970 EVO Plus. The PM983 datacenter SSD that uses the same Samsung Phoenix controller as the above client/consumer drives is being replaced by the PM983a. Download free la bruja german castro caicedo pdf descargar gratis. This update brings a doubling of capacities, now allowing for up to 16TB (presumably only on NF1 and U.2 form factors).

In the datacenter, SLC write caches are not used so the advertised write speeds are significantly lower than for the client/consumer drives, but there are still significant improvements here. The PM971a client NVMe BGA SSD is getting a significant update in the new PM991 that roughly doubles random I/O and sequential write performance and improves sequential reads by about 50%.

The enterprise SAS product line is not seeing any major changes to performance or available capacities, but the update from the PM1643 to the PM1643a does improve random write performance by about 20%. The largest model remains 30.72TB.

The high-end enterprise NVMe drives are getting a major controller update that brings PCIe 4.0 support in addition to the NAND upgrade. This allows for much higher performance across the board, most notably with sequential read speeds reaching 8GB/s on the new PM1733 compared to 3.5GB/s on the PM1723b. The maximum available capacity has caught up to the SAS product line with the introduction of a 30.72TB model. The PM1733 also introduces dual-port PCIe capability to this product line, providing a migration path for SAS SSD users who require this reliability feature. Rolling out QLC Samsung's naming scheme for enterprise and OEM SSDs uses model names starting with SM for drives with MLC NAND, PM for TLC NAND, and now BM for QLC NAND.

Four new QLC SSDs have been announced: the BM1733 and BM9A3 enterprise NVMe SSDs, the BM1653 enterprise SAS SSD, and the BM991 client NVMe SSD. All of these have obvious parallels with TLC-based PM-series models above, but Samsung has not yet shared detailed specifications for any of these QLC drives.
