Pure Storage’s coming high-end array: We have the details

Good post by Chris Mellor (thank you) over at El Reg

We can tell you a few more juicy details about Pure’s coming high-end array, and we’re deducing that SolidFire has a product capacity refresh coming.

What we knew was that the new range-topper would boast up to 1.5PB usable capacity using 4 and 8TB 3D NAND modules (SSDs). It would have always-on QoS, support thousands of virtual machines and be priced at less than $1GB/usable capacity.

SMR Drives: Are they too late to the game?

Good post by Petros Koutoupis (thank you)

The sudden popularity over NAND Flash has spelled doom for traditional magnetic Hard Disk Drives (HDD). For years we have been hearing how HDDs are reaching the end of their life. We have also heard the same about Tape drives, long before that. Although, it would seem that the prediction on HDDs may become a bit more of reality, sooner than expected.

Samsung announces 16TB SSD

Post by Robin Harris (thank you)

Not just the world’s highest capacity SSD, but the world’s highest capacity drive of any type. The PM1633 uses Samsung’s new 48 layer V-NAND, itself a technical tour-de-force, and represents a new thrust in flash storage beyond performance: capacity.

When Solid State Drives are not that solid

Post by Adam Surak (thank you)

It looked just like another page in the middle of the night. One of the servers of our search API stopped processing the indexing jobs for an unknown reason. Since we build systems in Algolia for high availability and resiliency, nothing bad was happening. The new API calls were correctly redirected to the rest of the healthy machines in the cluster and the only impact on the service was one woken-up engineer. It was time to find out what was going on.

Will Phase Change Memory Upstage Flash?

Post by Jim O’Reilly (thank you)

HGST is touting a solid-state drive with a record 3 million IOPS using PCM. The technology looks to be a game changer, but it faces several challenges.

The nonvolatile memory space just got very interesting with the recent demonstration of a super-fast phase change memory (PCM) drive by HGST, a Western Digital company.

Samsung: We’ve slashed programming time with 3-bit vertical NAND

Post by Chris Mellor (thank you) over at El Reg

Korean flash foundry king Samsung has announced the entry of 3-bit (TLC) flash in its V-NAND product line at the Flash Memory Summit.

The product has 32 layers of TLC NAND, TLC being triple-layer cell as opposed to the bulk of today’s business NAND products which use MLC or 2-layer cell with 2 bits per cell.

Samsung begins producing 32-layer 3D V-NAND SSDs

Post by Sean Portnoy (thank you)

The new drives provide eight more layers than the first generation of three-dimensional V-NAND flash memory and will be targeted to high-end PCs as well as data centers.

In the race to squeeze more data into the same storage form factors, Samsung rolled out its first solid-state drives using three-dimensional vertical NAND flash memory, which stacks 24 cell layers on top of one another, late last summer.

Samsung’s V-NAND: Hitting the Reset Button on NAND Scaling

Post by Anand Lal Shimpi (thank you)

SSD pricing has come down tremendously since Intel’s X25-M hit the scene in 2008. Back then we were talking about 80GB for around $600, while today Micron and Samsung will sell you a 1TB SSD for the same price. Moore’s Law drove this scaling in capacity.
