>What else would need such an extreme of SSD design?
need <> want, and I suspect that it's a want, which someone has disguised as a need as in 'we don't want the terry-wrists getting hold of this technology first!'.
ViON have produced a 100TB DRAM solid state drive, which they claim to be the largest flash memory-based storage box in the world. The HyperStor-6200 uses both Hitachi Data Systems and Texas Memory Systems technology - think RamSan 6200 - and provides five million I/Os per second (IOPS) with 60GB/sec bandwidth. It is a monster …
It's a backup of there "Personal entertainment" cough cough :D 60GB/s Makes for perfect HD streaming if you ask me.
Maybe this is the next step towards a better backup solution as tapes and ordinary HDD just dont provide the bandwith or storage required. With this i could backup my PC in just over 30 seconds
Memory stick that you carry in your bag = 8GB. 100 TB = 12800 of those.
Of course if you can build a big enough USB farm, park some ZFS on it and actually get some USB bus speed that can drive it, and you remember that you don't have any moving parts, you'r right, it is just not that cool.
RAID 1(+) mirrors so it protects against hardware failure.
Sure saying RAID protection can be misleading as RAID doesn't always involve mirroring.
And of course mirroring is not a complete backup solution, but it does offer protection, protection against hardware failure.
And of course it is wrong to say that RAID is just about availability, in fact more often it is about performance, whether striping on flash memory gives performance is probably worthy of investigation.
I unforget installing a 'ram disk' on Baker Perkins' IBM mainframe. It was the size of a couple of filing cabinets, and looked like a 10" removable platter disk drive to the OS, while being a hundred times faster.
It used about five horse-power's worth of electricity and contained something like 25Mb as I recall. Or would have done if the tight bastards had ordered it full.
At the time the streetlights outside were still gas-lit.
Western Digital has confirmed the board is considering "strategic alternatives" for the storage supplier, including spinning out its flash and hard disk businesses.
This follows calls last month by activist investor Elliott Management, which has amassed a $1 billion investment in WD equating to a six percent share stake, for a "full separation" based on those product lines.
In a statement, CEO David Goeckeler said: "The board is aligned in the belief that maximizing value creation warrants a comprehensive assessment of strategic alternatives focused on structural options for the company's Flash and HDD businesses.
Embedded World Chipmaker Micron is offering a microSD Card for embedded applications with an impressive 1.5TB capacity, enough to hold four months of continuously recorded security camera footage, according to the company.
Announced at the Embedded World 2022 conference in Nuremberg, Germany, Micron's new i400 [PDF] is claimed to be the highest-capacity microSD card yet and was designed with a focus on industrial-grade video security applications.
The device is sampling with potential customers now.
Samsung has dished up a new variety of SD card that can, it claims, sustain 16 years of continual writes.
The Korean giant's calculations for the longevity of the PRO Endurance Memory Card – for that is the new tech's name – assume their use to record 1920×1080 video content at 26Mbit/sec (3.25MB/sec).
At that rate, the 256GB model is rated to endure 140,160 hours of use. Smaller capacity models won't last as long because they'll be overwritten more often, so the 128GB, 64GB and 32GB each halve their larger sibling's lifetime.
Updated Activist investor Elliott Management is pushing for Western Digital Corporation's board to break the business in two by splitting the hard disk drive and NAND flash divisions into separately traded entities.
In an open letter to the board [PDF], Elliott – which has over time invested roughly $1 billion in WDC, representing about a 6 percent stake – says it is almost six years since WD bought SanDisk for $19 billion, scooping up its NAND memory biz.
At the time, this purchase was "nothing less than transformative", the letter adds, propelling five-decade-old WDC beyond HDDs into one of the biggest players in flash. Synergies, a better strategic position, and enhanced financial profile were among the rationale for the deal, says Elliott.
A consortium led by Chinese government-backed Beijing Jianguang Asset Management Co. Ltd (JAC Capital) has injected $9.4 billion into ailing Chinese chipmaker Tsinghua Unigroup, in a deal that will be appreciated by many big tech industry players.
Tsinghua Unigroup is a vast conglomerate that was spun out of Tsinghua University in Beijing and in 2015 had sufficient muscle to make a $23 billion bid for Micron Technology (which failed). The organization now consists of five units:
A new Linux kernel patch from a Google engineer resolves a problem caused by a condition that many of us might quite like to experience – having too many NVMe drives.
The problem is caused by the relatively long time it takes to properly shut down a drive: apparently, as much as four-and-a-half seconds.
Remember Sun's X4500 storage server, originally codenamed Thumper? It was truly radical when it appeared: a 3U dual-processor server, but with a stonking 48 drive bays. These days Google has a bunch of boxes with a still-fairly-impressive 16 NVMe drives attached to each one. And when they have to reboot, they take a long time.
Backblaze has published the first SSD edition of its regular drive statistics report, which appears to show that flash drives are as reliable as spinning disks, although with surprising failure rates for some models.
The cloud storage and backup provider publishes quarterly and annual Drive Stat reports, which focused exclusively on rotating hard drives until last year. Backblaze said it will initially publish the SSD edition twice a year, but that this may change depending on how valuable readers find it. The 2021 Drive Stats report was published in February.
In a blog post detailing the latest probing, Backblaze cloud storage evangelist Andy Klein said the SSDs are all used as boot drives in the firm's storage servers, and that Backblaze only began using SSDs this way from Q4 of 2018. He pointed out the drives do more than just boot the servers, they also store log files and temporary files produced by the servers, and so each SSD will read, write, and delete files depending on the activity of the server during the day.
Updated Users of Windows 11 are complaining about slow write speeds on NVMe SSD drives, a problem which persists even though it was acknowledged by a Microsoft engineer three months ago.
Production at Kioxia and Western Digital's 3D NAND fabrication facilities in Japan is being disrupted by chemical contamination, with at least 6.5 exabytes of capacity lost.
The two companies operate a joint venture which has six fabs at Yokkaichi in Mie province, employing some 8,000 people, and a seventh fab at Kitakami in Iwate province.
A Kioxia statement says that, in late January, a chemical used in 3D NAND production was found to be contaminated and production was affected. Measures are being taken to restore normal production. Manufacture of 2D NAND is not affected.
A team of researchers claim they can make SSDs impervious to ransomware attacks by detecting infections and reverting unexpected encryption within a matter of seconds, at the cost of a small increase in latency.
The group includes engineers from South Korea’s Inha University, Daegu Institute of Science and Technology, and the Cyber Security Department at Ewha Womans University (EWU) as well as a researcher from the University of Central Florida in the US.
"I came up with the idea of firmware level detection because I know that many [users] don't install anti-ransomware software," DaeHun Nyang, PhD, at EWU told The Register of the origin of the team's research project. "So I thought that it would be good if we can protect people not having anti-ransomware installed on their computers by providing them with an anti-ransomware-intrinsic SSD.
