Oh my Tosh, it's only a 100TB small form-factor SSD, SK?

Flash Memory Summit The Flash Memory Summit saw two landmark capacity announcements centred on 96-layer QLC (4bits/cell) flash that seemingly herald a coming virtual abolition of workstation and server read-intensive flash capacity constraints. Pop art style illustration of man exclaiming WHAT? in shock/horror/bemusement. Anyone fancy testing …

The age of hard drives is over as Samsung cranks out consumer QLC SSDs

Samsung has started mass production of the world's first QLC (quad-level cell) consumer SSD. QLC is 4 bits/cell flash technology and a next step in cell bit capacity from the current TLC (3 bits/cell). Foundries belonging to Intel/Micron, SK Hynix and WD/Toshiba have started producing QLC chips and, in some cases, SSDs already …

Up the stack with you: Microsoft's Denali project flashes skinny SSD controllers

Analysis Microsoft has lifted the lid on Project Denali, its quest to bring flash drive cost down a peg by extracting costly extra software from SSDs and running it in the host server to gain cost and performance efficiencies. It and co-developer CNEX Labs presented details about the project, along with its SONIC open switch networking …

NAND chips are going to stay too pricey for flash to slit disk's throat...

Analysis Flash chip bits cost eight times more than spinning rust and SSDs aren't going to get cheap enough to kill off disk entirely. The cost/TB of flash storage has been dropping for several years as chip capacity has increased through making smaller cells then layering cells with 3D NAND. It means you can get more chips from a NAND …

Who was the storage dollar daddy in 2017? S. S. D

Customer spending on SSDs finally ruled the storage roost in 2017 but vendors still shipped more than ten times as much disk capacity as flash. IDC numbers for the fourth 2017 quarter and full year, tweaked by Wells Fargo senior analyst Aaron Rakers, revealed the revenue crossover between the two tech types: …

Pro Evo-lution shocker: Samsung SSDs focus on endurance over capacity

Samsung's new 860 Pro and Evo SSDs have virtually the same capacity and performance as the 850 line, but with much higher endurance. The 850 drives were launched in 2014 and boasted 128GB to 2TB capacity in 2.5-inch form factors with a 6Gbit/s SATA interface. They used 32-layer V-NAND, Samsung's version of 3D NAND – 2bit/cell …

IBM Zurich wants to spice up your life with SALSA translation layer

Research gnomes at IBM Zurich say we should take translation layers off storage devices and run many at the same time on a server to get faster IO. They have published a research paper discussing this. An SSD has a Flash Translation Layer (FTL), which interfaces between the database and file system concepts on the host system …

Rowhammer RAM attack adapted to hit flash storage

It's Rowhammer, Jim, but not as we know it: IBM boffins have taken the DRAM-bit-flipping-as-attack-vector trick found by Google and applied it to MLC NAND Flash. Google's Project Zero found Rowhammer in 2015, when they demonstrated that careful RAM bit-flipping in page table entries could let an attacker pwn Linux systems. …
