What do people want? If we're talking mainstream enterprise SATA SSDs, reliability, chirps Micron

Micron is looking to boost its high fidelity cred. The vendor has refreshed its three-model 5100 SATA SSD with a two-variant 5200, increasing reliability from two million to three million hours mean time before failure (MTBF). The 5100 SATA 2.5-inch SSD was built from 32-layer TLC 3D NAND came in three flavours: Eco (high …

What is this – some kind of flashy, 3-bit consumer SSD? Eh, Seagate?

Seagate has a new line of Nytro consumer SSDs coming using 3-bits/cell flash. These 2.5-inch form factor consumer SSDs are typically positioned as PC/notebook disk drive upgrade products, providing a data access, app load and boot time performance boost for such disk-bound products. A 256GB Nytro 141 appears to be available …

Irish flash extender startup goes 3D

Flash drive life extender NVMdurance has enlarged its market by developing techniques for extending the life of 3D flash drives. Its current Pathfinder product is a suite of machine learning algorithms that can be applied to planar (2D) MLC (2bits/cell) and TLC (3bits/cell) flash to find the best way register values for NAND …

Micron wheels out 'highest density' SATA SSD on the market

+Comment Micron has introduced a 5100 line of data centre flash drives and promises it will be the highest-density SATA SSD on the market. There are three models and they all use TLC (3bits/cell) 3D flash and have a 6Gbps SATA interface: 5100 ECO – 480GB, 960GB, 1.9TB, 3.84TB and (coming) 7.86TB 5100 PRO – 240GB, 480GB, 960GB, 3. …

Intel punches out data centre flash cardlet

Intel has released a tiny, single-sided and heavily read-optimised SDD for server use in data centres. The P3100 is an M.2 design (22 x 80mm) built from 3D TLC (3bits/cell) NAND. This format has begun appearing in tablets, thin notebooks and desktops as it doesn't take up much space and the use of TLC (3bits/cell) NAND means …

Flash reaches the enterprise tipping point

Comment The use of disk drives to store performance data for enterprises is declining and, flash drives - SSDs - are taking their place. A wave of all-flash array (AFA) to disk array migration is starting to wash across data centres as generations of disk drive arrays give way to ones built with NAND flash drives. The tipping …

Great, IBM has had a PCM breakthrough. Who exactly is going to manufacture?

Analysis IBM has demonstrated a 3-bit Phase-Change Memory chip with IBM Zurich researcher Dr. Haris Pozidis talking about it in a YouTube video and not mentioning 3D XPoint once. The idea is to counter the relatively high cost of PCM chips by giving them 3 bits per cell, TLC or triple-level cells, instead of just one - clever. This …

Alphabetti spaghetti: SanDisk adds SLC cache to TLC SSD

Acronym alert: SanDisk has upgraded its Z400 PC SSD by changing it from an MLC drive to a TLC one with an SLC cache, doubling its capacity as well making it faster. The Z400 SSD used 15nm MLC (2 bits/cell) flash when it was introduced a year ago. SanDisk has kept the 15nm NAND but changed it to TLC (3bits/cell), upping its …

What did the one Toshiba desktop SSD say to the other? Our cell size has shrunk

Toshiba is busily upgrading its PC/workstation SSD line at the same time as it’s scaling back its PC product activities. Its Q300 and Q300 Pro consumer/gamer SSDs were announced in September last year. The Q300 was a TLC (3bits/cell) unit storing 120, 240, 480 or 960GB of data while the Q300 Pro used MLC (2 bits/cel) NANd and …

Toshiba rolls out PC-busting monster: 1 terabyte TLC flash SSD

It’s a PC disk drive killer: a 1TB SSD built by Toshiba, using TLC flash, and built with 15nm cell lithography. The SG5 series comes in both M2 and 2.5-inch SSD format and signals a wave of product refreshes as Toshiba's existing 19nm SSD products are changed over to use denser 15nm NAND during the next six to 12 months. With …

Micron has three bits between its PC disk-killing flash teeth

Micron is targeting consumers and SMBs with a disk-replacing three bit Crucial-brand SSD. This BX200 triple-level cell (TLC) 2.5-inch flash drive uses Micron NAND chips, 16nm ones, and comes in 270GB, 480GB and 960GB capacity levels. It is driven by a Silicon Motion SM2256 controller operating Micron firmware. The basic …

Flash in the pan? Dell 3D TLC AFAs are cheaper than spinning rust

Dell is hitting a $1.66/GB all-flash array street price point using 3D TLC flash drives from Samsung, the first enterprise array supplier to go 3D and TLC. TLC (triple-level cell) NAND has 3 bits per cell and its production cost is roughly two thirds of 2-bits/cell MLC flash, the bulk of storage array flash shipped today. It’s …

Micron blames dismal PC sales for EVERYTHING

Memory firm Micron's third fiscal 2015 quarter results were pretty poor - and the chief exec blames the slumping PC market. Revenues of $3.85bn were three per cent down on a year ago and eight per cent down sequentially. Net income of $491m compared poorly to the $806m reported a year ago and the $934m in the previous quarter …

Pure's mass disk drive killer lays out plans for flash hegemony

Comment Fresh from a big product and business model launch, Pure Storage was undestandably reticent about future technologies at a briefing in Mountain View. However, interesting tidbits did drop from speakers' lips. Co-founder John "Coz" Colgrove said: "Our goal is to make all disk storage extinct." Dressed in his signature long t- …

Disk is dead, screeches Violin – and here's how it might happen

Analysis And in a flash, disk is dead. Well, actually, not that fast. But flash array flogger Violin Memory is convinced disk is dying in the data centre, killed by a series of NAND acronyms: 2D MLC, 3D TLC and, the final blow, 3D QLC. Is this view realistic? Even remotely realistic? It starts from a pair of observations by Violin …

Flash dead end is deferred by TLC and 3D

Comment The arrival of a flash dead-end is being delayed by two technologies, both involving the number three – three-level cell (TLC) flash and three-dimensional (3D) flash – with the combination promising much higher flash chip capacities. As ever with semi-conductor technology, users want more data in the same space and faster …

Kaminario playing 3D flash chippery doo-dah with its arrays

Interview Twitter can be great. There we were, we storage twits, talking about 3D flash, when Kaminario CTO Shachar Fienblit got in touch to say Kaminario was using 3D flash already. That makes it the first enterprise storage supplier to go 3D NAND, as far as we know, and has an 800GB 3D NAND SSD in its set of flash media. We got in …

All the flash world needs is more TLC, suggests report

Triple-level cell (TLC) flash is heading towards being nearly half of all flash shipments. A report from DRAMeXchange says TLC NAND flash will account for nearly half of the total NAND flash output in the fourth 2015 quarter. DRAMeXchange_TLC_chart The report author, Sean Yang, says TLC NAND is shifting from memory card and …
