Patriot Also Shows Off Burst and P200 SATA SSDs

Patriot Memory's SSD lineup for 2019-20 includes two new SATA SSDs to cater to the mainstream market, the P200 and Burst. Both drives are built in the 2.5-inch form-factor, with SATA 6 Gbps interface. The Burst is available in capacities of up to 960 GB, and is powered by a Phison S11 controller with DRAM cache. The drive offers sequential transfer rates of up to 560 MB/s reads, with up to 540 MB/s writes, and endurance of up to 835 TBW, benefiting from the drive's overprovisioning. The P200 is an interesting drive, in that it comes in two controller options. Capacities 256 GB, 512 GB, and 1 TB ship with Silicon Motion SM2258XT DRAM-less controller, while the 2 TB version is powered by a Maxiotech MAS0902A. On offer are up to 530 MB/s reads, up to 460 MB/s writes, and up to 1 PBW endurance.

Kingston Technology Launches New Data Center 500 Series SSDs

Kingston Digital, Inc., the Flash memory affiliate of Kingston Technology Company, Inc., a world leader in memory products and technology solutions, today announced it is shipping the Data Center DC500R Enterprise SSD optimized for read-intensive applications. This is the first drive in the DC500 series that implements Kingston's strict Quality of Service (QoS) requirements to ensure predictable random I/O performance as well as predictable low latencies over a wide range of read and write workloads. Next week, the company will ship its DC500M SSD optimized for mixed-use workloads.

DC500R is ideal for read-intensive applications such as boot up, web servers, virtual desktop infrastructure, operational databases and real-time analytics. Cloud service providers and software-defined storage architects can leverage the drive's consistent I/O and latency performance to deliver the QoS needed in demanding read-centric environments. At .5 DWPD (drive writes per day), DC500R allows IT administrators to maximize their investment in storage hardware with a drive that delivers on performance, endurance and reliability. DC500R is available in 480GB, 960GB, 1.92TB and 3.84TB capacities.

Plextor Intros M8V Series Value SATA SSDs

Plextor today introduced its latest line of value SATA SSDs, under the M8V series. Available in 2.5-inch and M.2-2280 form-factors, the drives leverage SATA 6 Gbps interface, combining Toshiba's latest-generation 64-layer BiCS TLC NAND flash memory, with Silicon Motion SM2258 controller. This controller offers LPDC and redundant array of NAND flash. Both variants come in capacities of 128 GB, 256 GB, and 512 GB.

Performance differs by capacity variants. All three capacity-variants read at speeds of up to 560 MB/s. The 128 GB, 256 GB, and 512 GB variants write (sequentially) at speeds of up to 400 MB/s, up to 510 MB/s, and up to 520 MB/s, respectively. Their 4K random-access speeds are rated at 60,000/70,000 IOPS (reads/writes), 81,000/80,000 IOPS, and 82,000/81,000 IOPS, respectively. Plextor rates their endurance at 70 TBW for the 128 GB variant, 140 TBW for the 256 GB variant, and 280 TBW for the 512 GB variant. Plextor is backing these drives with 3-year warranties.

Samsung 860 EVO SSD Makes an Appearance

Hot on the heels of Samsung updating its website with its next performance-segment SSD 860 Pro series, with its range-topping 4 TB variant, a similar pre-launch website update revealed the company's next mainstream SATA SSD, the 860 EVO. The drive will be available in three form-factors, 7 mm-thick 2.5-inch, M.2-2280, and mSATA; all with SATA 6 Gbps interface. The 2.5-inch version comes in 250 GB, 500 GB, 1 TB, 2 TB, and 4 TB variants; while the M.2-2280 version comes in just 500 GB, 1 TB, and 2 TB variants; and the mSATA version in 250 GB, 500 GB, and 1 TB variants. The drives combine Samsung's latest generation 3D VNAND flash memory built in the 10 nm-class sliicon fabrication process, with an updated controller and refined firmware.

The 860 EVO offers sequential transfer rates of up to 550 MB/s, with up to 520 MB/s sequential writes, up to 97,000 IOPS 4K random reads, and up to 88,000 IOPS 4K random writes. The new-generation flash is rated for "8 times higher" endurance than the 850 EVO series; with up to 2,400 TBW. Samsung is reinforcing its faith in the drive by backing it with 5-year warranties. The company is introducing the new TurboWrite feature, which is a user-configurable SLC cache. You can set anywhere between 12 GB to 72 GB of the NAND flash to function as SLC, so the controller can juggle hot data in and out of it, for improved performance, using the Samsung Magician software.

ADATA Launches ISDD336 and IUDD336 Industrial-Grade SD Cards

ADATA Technology, a leading manufacturer of highperformance DRAM modules and NAND Flash products,today launched industrial-grade ISDD336 SD cards and IUDD336 microSD cards. Diversifying ADATA offerings for industrial storage, all models feature wide temperature tolerance as well as shock, vibration, and humidity resistance well beyond consumer product ratings. ISDD336 and IUDD336 cards utilize durable and long-lasting 3D MLC NAND Flash, and are fully compliant with SD 3.0/SPI specifications, making them reliable choices for embedded systems. Performance across the board reaches 95MB/s read and 90MB/s write. Customers can choose ISDD336 SD cards in 16GB to 256GB capacities, and IUDD336 microSD cards in 16GB to 128GB capacities.

ADATA continues to increase its focus on industrial-grade products, with more offerings for users. As the SD standard has clear advantages for industrial customers thanks to its compact form factor, durability, and low power requirements, ADATA strives to provide more choice in the SD space. Thus, ISDD336 cards arrive in SD form factor while IUDD336 cards deliver the same quality and performance in microSD.

Samsung 850 Pro SSD Reaches End of Life With 9100 TB Written

No, that isn't a major typo on this article's headline. According to print magazine c't, who conducted a test bench consisting of two pieces each of OCZ's TR150, Crucial's BX 200, Samsung's 750 Evo, Samsung's 850 Pro, SanDisk's Extreme Pro and SanDisk's Ultra II, the last SSD to actually give out the last breath was Samsung's 256 GB 850 Pro, with a staggering 9100 TB (that's 9.1 Petabytes) written. This is well beyond Samsung's suggested longevity for this particular SSD, which stands at 150 TBW.

The first particular model to give out was one of Crucial's BX 200, at 187 TBW (still more than twice over the manufacturer's 80 TBW). The second model to fail was the second Crucial BX 200, at 280 TBW. The remaining SSDs apparently died after a power peak (unclear whether a surge or a spike), save for the Pro models, in the form of SanDisk's Extreme Pro and Samsung's 850 Pro (it seems those Pro-oriented features do serve some purpose, eh?.) One of these SanDisk Extreme Pro models lasted for about 2,200 TBW, the same amount of writes the first Samsung 850 Pro model endured. However, the second Samsung 850 Pro broke through all records with its total 9,100 TB written. Naturally, these are interesting and impressive overall results, but they can't really be counted upon as being statistically significant; two models each aren't enough to achieve a representation of the tested SSD models' endurance. However, this also probably means that save a defect on your SSD's manufacturing, you can count on it for a considerable amount of writes.
