Intel and Micron have just jointly announced shipment of the first quad-level cell (QLC) NAND-based SSD in the industry: the Micron 5210 ION, which is aimed directly at read-intensive cloud workloads. Intel-Micron say that the new QLC NAND has 33 percent greater bit density than TLC NAND, which gives it the ability to address opportunities in the market that used to be serviced only by lower cost, higher density Hard Disk Drives (HDD). QLC technology allows the SSD to reach 1-terabit densities using a 64-layer 3D NAND structure. However, the Intel-Micron team also notes 96-layer QLC NAND is... Read more...
Intel has released a dizzying array of solid state storage products over the last few weeks. We recently took a look at a pair of Intel Optane SSD 800P series drives for enthusiast desktop and mobile systems, and also tinkered with the impressive Intel SSD DC P4600 series enterprise-class NVMe drive. Today, we’ll stay in the enterprise space and inspect a pair of Intel’s recently-announced SSD DC P4510 series drives, which target cloud storage applications with impressive throughput and latency characteristics. The Intel SSD DC P4510 series is an evolution of the existing SSD DC P4500,... Read more...
Last year, Intel updated its line-up of NVMe, PCI Express-based solid state drives, for cloud and data center applications, with a couple of different models tuned for different workloads. The Intel SSD DC P4600 we will be showing you here was among those drives. It features a fourth-generation Intel controller and performance-optimized firmware, along with 3D TLC NAND flash memory (384Gb per die). If you remember, the DC P3700 we looked at a few years back had an 18-channel controller and MLC NAND, so the P4600 may sound like a downgrade in some respects, but as you’ll see a little later,...

Surging NAND flash and DRAM memory chip pricing has prompted China's economic regulator to look into whether or not suppliers such as Samsung and others have engaged in price fixing shenanigans. The chips in question are found in a variety of electronics products, most notably mobile phones, which use both NAND flash and DRAM ICs for permanent and temporary storage duties. "We have noticed the price surge and will pay more attention to future problems that may be caused by 'price fixing' in the sector," said Xu Xinyu, an official with the Pricing Supervision Department of the National Development...

NAND flash helps to make our [electronic] world go 'round and 'round. NAND flash is used in everything from our smartphones to our tablets to our notebook computers to numerous IoT devices that float in and out of our everyday lives. For the past year, demand has outstripped supply with regards to NAND flash, which has resulted in higher prices. However, DRAMeXchange is forecasting that that trajectory is set to change during the first quarter of 2018. The fourth quarter is traditionally the hottest selling period in tech, while the first quarter is traditionally one of the slowest periods. Thanks... Read more...
Western Digital today announced that it has successfully developed four bit-per-cell (also known as X4) 3D NAND built using 64-layer, BiCS3 technology. The company says that these chips can store 768 gigabits on a single chip (equivalent to 96GB), which is a 50% increase from 512 gigabit three bit-per-cell NAND (as basic math verifies). WD's X4 3D NAND was designed with the help of the company's work with X4 2D NAND, and one thing in particular the company is really proud of is the fact that its QLC flash delivers performance similar to that of X3 three bit-per-cell NAND. What that means is that... Read more...
There might not be a storage medium that's definitively indestructible, or perfectly reliable, but solid-state storage would rank near the top. A hard drive, for example, might be able to house a large amount of data, but if it's dropped to the ground, or its host PC is bumped hard enough, all of that data could effectively be ruined in the blink of an eye. Solid-state storage is a bit different. If it's jostled during operation, it won't be affected, and the same goes for experiencing a fall to the ground. But, despite its durability, it's still not indestructible or entirely reliable, and new... Read more...
It looks as though Western Digital could improve its position in the NAND flash market thanks to an impending deal with segment originator Toshiba. Toshiba announced today that it will spin off its NAND flash business (including its SSD operations), and will sell a minority share in order to raise capital.  It’s reported that Western Digital is the leading candidate purchase the minority share, with Reuters saying that the company could take a 20 percent stake. This would still leave Toshiba with 80 percent of its profitable business. "Toshiba has positioned the memory business as a focus... Read more...
Western Digital is the king of the hard drive market but up to now has been a non-factor in SSDs. However, with its purchase of solid state storage giant, SanDisk, the company immediately leaped to the forefront of the market in one fell swoop. Now the company is entering the consumer/commercial SSD market with WD Green and WD Blue SSDs, using a naming scheme borrowed from its hard drive line and technology acquired from SanDisk. WD's Green lineup is for entry level PCs meant to have a low power draw while the Blue SSD series is aimed at mainstream consumers. Both series are available... Read more...
Although NVMe PCI Express solid state drives are all the rage as of late, due to their relatively strong performance and inherent feature benefits, manufacturers continue to tune and refine their SATA based offerings as well. Case in point: the brand new OCZ VX500 series solid state drives we’ll be showing you here today. The OCZ VX500 series targets the mainstream computing segment and initially consists of a quartet of 2.5mm SATA SSDs, packing all, in-house, Toshiba made technology. The hook is, even though these new drives are priced aggressively, they eschew less expensive TLC NAND in favor... Read more...
A couple of weeks back, Intel announced a slew of new solid state drives, targeting a wide array of market segments, that leverage 3D TLC NAND. One of those offerings was a new series of M.2 NVMe drives, dubbed the SSD 600P. According to Intel, the SSD 600P series is “designed to deliver PCIe performance at near-SATA prices”. To date, most NVMe PCIe solid state drives are roughly 1.5 – 3x the cost per gigabyte of SATA based drives, due to the inherent performance benefits and likely the added cost of NVMe controllers. But, as the company has done a number of times in the past dating all the way... Read more...
This past summer, Intel and Micron jointly announced a new type of memory they call 3D XPoint. While new memory types seem to emerge all of the time, this one stood out based on the fact that it's being touted as 1,000x faster than NAND. It almost seems too good to be true, and I guess that's all it is until we begin to see production silicon trickle out onto the market. Nonetheless, Intel and Micron have just found themselves more competition with a duo involving SanDisk and HP. On the SanDisk side, the company has been tightly integrated into the memory and storage market for quite some time,... Read more...
SanDisk has announced the release of third-generation Fusion ioDrive PCIe and Mezzanine flash cards, in doing so marking the first integration of SanDisk NAND flash and Virtual Storage Layer (VSL) software into the ioMemory product line since the company acquired Fusion-io in June 2014 for $1.1 billion. Flash technology has moved significantly forward since the SanDisk's acquisition of Fusion, with smaller geometries and denser dies, all of which mean more flash capacity can now be placed on a PCIe flash card with performance raised and/or prices cut. Which explains why SanDisk is saying that their... Read more...
Depending on the "3D" we're talking about, it could either be amazing, or "meh". 3D gaming? Awesome. 3D movies? Meh. 3D memory? Incredible. Why? Because with 3D stacked memory technology instantly gives a hearty boost to both density and bandwidth. There's a reason both AMD and NVIDIA are going to be making use of 3D memory in their respective future graphics cards. To help put things into immediate perspective, take a look at the "gumstick" SSD in the shot above (the long card). Because of their 3D memory, Micron and Intel say that hitting 3.5TB on drives of this size will be possible. Meanwhile,... Read more...
