ADATA SU800 Series SATA SSDs Gets a 2TB Variant

ADATA Ultimate SU800 launched mid-2016 to compete with performance-segment SATA SSDs of the time, such as the 850 EVO. It was one of the first drives in its segment to implement 3D TLC NAND flash, and came in capacities ranging between 128 GB to 1 TB. Two years later, ADATA augmented this series with a new 2 TB variant to go after the crowd that wants to take advantage of low NAND flash prices to grab a high capacity SATA SSD to use as a game library drive.

The new 2 TB variant (ASU800SS-2TT-C), continues to be based on the Silicon Motion SM2258G controller, cushioned by a DRAM cache, and uses Micron-made 3D TLC NAND flash. It uses up to 8 percent of its TLC NAND flash as SLC cache. The drive offers sequential transfer rates of up to 560 MB/s, with up to 520 MB/s sequential writes, and endurance of up to 1,600 TBW. LDPC (low density parity check code) and in-built DVESLP mode support make up its feature-set. Backed by a 3-year warranty, the drive is expected to be priced around $379.

SK Hynix Unveils 4D NAND Flash Memory Concept

3D NAND flash revolutionized flash storage as it used the third dimension (height) to stack multiple NAND flash layers, resulting in infinitesimally smaller footprint and reduced costs. SK Hynix believes that a "4-dimensional" NAND flash package is possible. Don't worry, such a stack doesn't look like a tesseract. Conventional 3D NAND flash relies on stacks of charge-trap flash (CTF) cells spatially located alongside its periphery block (which is responsible for wiring out each of the layers of the CTF stack). On a 2-D plane you'd be spending substrate real-estate on both the CTF and periphery block.

SK Hynix believes that the periphery block can be stacked along with the CTF stack, with microscopic vias wiring up the stack along the periphery, reducing the footprint of each cell stack. 4D stacking will also allow for greater number of CTF stacks per cell. Just to be clear, we're talking about stacks of cell and not stacks of NAND flash dies. The V5 cell-stack in SK Hynix's design entails 4 cells and periphery blocks sandwiched. The first implementation of this technology is a 96-layer 4D NAND flash chip with 512 Gb of capacity and TLC (3 bits per cell) density, although the technology is ready for QLC cells. This 512 Gb chip will begin sampling by the end of 2018, and the company is already working on a 1 Tb chip for 2019.

The company didn't reveal pricing as the drives could be served up to enterprise customers.

Realtek Intros RTS5762 NVMe SSD Controller Capable of 3500 MB/s Reads

Realtek, known more for its cheap Ethernet PHYs and audio CODECs, entered the SSD controller market in 2017, with mainstream SSD controllers. This year, the company plans to take on giants such as Silicon Motion, Phison, Intel, and Samsung, with its own high-performance controller, the RTS5762. The PCI-Express 3.0 x4 interface provides 4,000 MB/s of raw bandwidth per direction, and while it's technically impossible for any device to transfer its payload data at that speed (on account of various protocol overheads), very few PCI-Express 3.0 x4 SSDs get within 80th percentile of it (3200 MB/s per direction transfers). It's only recently that 3400 MB/s became the gold-standard of high-end M.2 NVMe SSDs, but Realtek plans to change that.

The RTS5762 is capable of up to 3,500 MB/s reads, or 87.5% saturation of the PCI-Experss 3.0 x4 bus. It supports up to 8 NAND flash channels, 3D TLC and 3D QLC NAND flash memory, and takes advantage of the newer NVMe 1.3 protocol. The only other controller right now that's capable of 3,500 MB/s reads is Samsung "Phoenix," found exclusively on the 970 Pro series (and no other brand's products). Sequential write performance is where this Realtek chip edges past Samsung, with the company showing CDM performance of up to 3,000 MB/s writes, whereas the 970 Pro is only specified to write up to 2,700 MB/s. Realtek also beefed up its mainstream NVMe controller portfolio with the new RTS5763DL. If drives based on this chip are priced right, it could carve out a new market segment between cheaper PCIe 3.0 x2 drives, and "upper mainstream" x4 drives such as the Samsung 970 EVO. Armed with just 4 NAND flash channels and no DRAM to cushion it, the RTS5763DL reads at up to 2150 MB/s, and writes at up to 1475 MB/s (as tested on CDM), making it faster than PCIe 3.0 x2 drives, at least in the sequential reads test.

Toshiba First to Deliver Value SAS SSDs Targeting SATA Applications

Today Toshiba Memory America, Inc., the U.S.-based subsidiary of Toshiba Memory Corporation, unveiled a new, game-changing category of SAS SSDs expected to replace SATA SSDs in server applications. The RM5 12Gbit/s value SAS (vSAS) series features capacity, performance, reliability, manageability and data security advantages - at a price that obsoletes SATA SSDs.

Crucial Starts Selling MX500 2.5-inch SSD Models

Crucial started selling all four models of its premium SATA SSD, the MX500. The drive was launched earlier this month. It comes in 250 GB, 500 GB, 1 TB, and 2 TB variants; and in the 2.5-inch form-factor, with SATA 6 Gbps interface. M.2-2280 variants with SATA interface, which were shown off at the 2018 International CES, could launch a little later this year. The 250 GB variant is priced (MSRP) at USD $79.99 ($0.31 per GB), the 500 GB variant at $139.99 ($0.27 per GB), the 1 TB variant $259.99 ($0.25 per GB), and the range-topping 2 TB variant $499.99 ($0.24 per GB). All four models come with 5-year warranties.

Crucial MX500 combines Micron's 2nd generation 64-layer 3D TLC NAND flash memory with a Silicon Motion SM2258 controller, and a custom firmware by Crucial. The NAND flash chips by design offer the same levels of power-loss protection as drives that need capacitor banks to do so. Among its features are Dynamic Write Acceleration (SLC-cached writes), and Redundant Array of Independent NAND (RAIN). All four variants offer sequential transfer rates of up to 560 MB/s with up to 510 MB/s writes, and 4K random access performance ratings of up to 95,000/91,000 IOPS (reads/writes).

Marvell's Ready to launch QLC Controller Delivers 670K IOPS

QLC is the next big step in flash memory, with another bump in density increases and, crucially for consumers, revised, lower pricing for flash-based products that employ the new technology. We've already had a sneak peek at what QLC-based products can deliver - Intel's leaked SSD 660P employs QLC memory and is expected to deliver 1,800 MB/s in sequential read and up to 1,200 MB/s in sequential write speeds with 150,000 IOPS. Expect base drive capacities to increase - QLC being higher density would mean fewer NAND chips, but manufacturers want to keep the added performance of chip parallelism.

However, flash needs controllers to deliver its true potential, and Marvell has one up its sleeve. The new controller will eventually replace the NVMe 1.1 Eldora (88SS1093) used in some popular SSDs that are already shipping, such as Plextor's M9Pe, and the folks at Tom's hardware took a peek at it - running the current TLC memory, that is. The controller delivered over 670,000 IOPS and 3,500 MB/s in the demo, though there's no information on the density of the drive. But for those performance levels, it must've had a good amount of silicon. While not representative of final QLC memory performance of the controller, it's good to know that at least this part of the ecosystem is good to go. Now if only QLC was quick and hot off the presses, we could see a $100 512 GB SSD.
