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. …

Samsung's bantam SSD makes WD's 'passport' drive look passé

Samsung has introduced a 2TB T5 portable SSD you can stick in your shirt pocket. It comes in metallic blue with 250GB and 500GB capacities and black for 1TB and 2TB versions. It measures 74 x 57.3 x 10.5mm and weighs 51g, although precise weight varies by capacity. That's smaller than the average portable disk drive. …

NAND that's that... Flash chip industry worth twice disk drive biz

Analysis The flash industry is worth more than twice the disk drive industry in terms of product ship revenues. Trends suggest a shrinking disk drive industry will squeeze the three drive manufacturers, leaving Seagate with no escape. Storage sector analyst Aaron Rakers has run supplier numbers through his spreadsheets and reckons the …

Still no flash in a flash as chip supplies remain fried

Five months after the Reg first reported that HPE, Cisco – and even Dell EMC – were being punched hard in the supply chain by worldwide flash chip shortages, it's still a problem for at least one vendor. A Reg reader forwarded this alert message from an HPE system configurator: ALERT! Due to an industry-wide shortage, all non …

Still got a floppy drive? Here's a solution for when 1.44MB isn't enough

Floppy disk sales have, well, flopped but there are still masses of PCs and old embedded PC-based systems out there with floppy disk slots and drives. Now this near-dead space can be made usable again, with a 32GB FLOPPYFlash drive from Solid State Disks Ltd. It's a drop-in replacement for a floppy disk drive and takes …

Disk death: Three-quarters of PCs will run SSDs by 2020

Total disk drive shipments are going to plummet by 2020, with raw SSD cost getting cheaper than disk and SSDs taking over from disk in notebooks. Analyst haus Stifel Nicolaus's MD, Aaron Rakers, has taken a close look at Gartner’s HDD and SSD projections over the next few years. He writes: “Gartner is currently forecasting …

Super-slow RAID rebuilds: Gone in a flash?

Analysis RAID rebuilds are too slow with 4, 6 and 8 and 10TB drives. So erasure coding is coming in to shorten the failed disk data rebuild time and also use less capacity overhead. What happens when SSDs are used instead of disk drives? Will RAID be more or less acceptable than with disk drives? Intuitively we expect a flash array to …

Hold on a sec. When did HDDs get SSD-style workload rate limits?

Storage Architect A recent Register article reminded me that hard drive vendors are introducing warranty limits on their products for the amount of data that can be written to them in any one year. SSDs have always had this restriction; does the same now apply to HDDs? Solid state drives (SSDs) have always had this restriction because we know …

ARM Cortex-R8 aka 'Now your hard drive will have a quad-core CPU in it'

Brit processor designer ARM has drawn up a quad-core Cortex-R8 CPU so storage drives can cope with the demands of increasing capacities – and phones can download stuff faster. The Cortex-R family is aimed at real-time applications: code running on the cores must react to interrupts and other events within tight deadlines and …

Eight budget-friendly 1TB SSD data packers for real people

It wasn’t that long ago that the idea of a 2.5in 1TB class SSD roundup would have been laughable mainly because the very idea of a 1TB drive aimed at the consumer market would have been considered a flight of fancy. Until recently large capacity SSDs were the domain of the corporate and enterprise sectors with the accompanying …
