Samsung PM835T TLC SSD

Hey, Samsung: Why so shy about your 960GB flash drive's endurance?

Samsung has gone and used cheap-to-make triple-level cell NAND chippery to make an SSD for data centre use. Will it catch on? Triple-level cell (TLC) flash chips mean fabs can extract more flash capacity from a silicon wafer, and so production costs are lower than for two-level cell MLC technology. Samsung says it gets "a 30 per …

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 …

The storage is alive? Flash lives longer than expected – report

StorageBod The Tech Report has been running an ‘SSD Endurance Experiment’ utilising consumer SSDs to see how long they last and what their "real world" endurance really is. It seem that pretty much all of the drives are very good and last longer than their manufacturers state. It's a fairly unusual state of affairs – something in IT that …

IBM's FlashSystem 900: ‘Better capacity in less rack space’

IBM has upgraded its FlashSystem 840/V840 to the 900/V9000 all-flash array products, using MLC flash in a close collaboration with Micron to prevent any performance or reliability drop-off. The V9000 is as we described here and the 9000 product that we thought should exist but couldn't find, the upgraded 840, does actually exist …

Flash is fallible. But you'd rather have an AFA than spinning rust

We tend to think of flash as a solid-state disk – like spinning rust, only more expensive, consuming less power, and much, much faster. And yes, it is true that you can use it like that, but there is a lot more that flash can offer if you start to take into consideration what makes flash different in the first place. Simply put …
