Stamp-sized 1TB SSDs coming soon?

Crunchgear reports about a breakthrough in flash memory production; a Japanese team of scientists have developed a technology that allows a 90% reduction in SSD size, while also reducing power usage and costs.

The full report can be read in The Nikkei; the chip supposedly uses radio communication instead of traditional copper interconnects between [...]

Micron buys flash maker Numonyx

Micron Technology, one of the world’s leading memory manufacturers, has announced they will acquire flash maker Numonyx. The deal is an all-stock transaction, worth about $1.27 billion.

The deal makes Micron the number two memory maker behind Samsung Electronics, switching places with the new number three Hynix. Interestingly, Numonyx currently has a joint venture [...]

Riverbed adding solid state storage to WAN accelerators

Riverbed is turning to Solid State Drives to increase the speed of their WAN acceleration products. The two new Steelhead 7050 models can deliver up to 1 Gbps of WAN capacity for data center workloads, and 622 Mbps for remote office scenario’s; the previous-generation 6050 maxed out at 310 Mbps.

TDK says 3TB hard drives coming later this year

TDK’s most recent roadmap shows some new developments. The most important thing I found in this presentation was a roadmap for the next generation of HDD read/write heads.

EC2 performance issues, what about S3 and EBS?

As reported around the web, it looks like several people have noticed performance issues with Amazons EC2 cloud computing service. While this was to be expected, some people are surprised nonetheless. For those that are surprised: please read “the truth about overselling“. It’s about web hosting, but much of the contents are true for cloud computing as well. Cloudkick has nice graphs showing the latency to their EC2 instances:

SuperMicro adding double-sided storage server chassis

SuperMicro, one of the largest suppliers for “white-box” computer makers, presented their solution for high-density storage servers last month. Most traditional storage servers offer twelve 3.5 inch SAS or SATA drives per 2U of rackspace; the only exception to this are vendors offering top-loading drives such as Sun, and those offering disk trays holding more than one drive mounted back-to-back.

SuperMicro has a more traditional approach, but with a twist. Their highest density server chassis now offer extra drive slots that are accessible via the rear of the server:

Toshiba doubles NAND flash size

Toshiba just announced their next generation of flash memory chips. The new lineup consists of single-chip packages that combine a number 32 gigabit NAND flash chips and a controller into a single FBGA package. Using their 32 nanometer production process, the chips are significantly thinner than the previous generation.

Future of MySQL: How serious is Oracle about open source?

During the last days, the the fight over MySQL’s future has heated up. The European Commission still hasn’t approved it, and Michael Widenius is calling upon all MySQL users to help “save” the popular open source database from Oracle. As a response, Oracle has published some promises about MySQL’s future that were meant to provide some counterweight to this call for help. I think these provide some interesting insights into what Oracle has planned. Continue reading Future of MySQL: How serious is Oracle about open source?

Intel and Numonyx improve phase-change memory

Intel and Numonyx have just announced that they have achieved an important breakthrough in he production of Phase-Change Memory. This type of memory is one of the most promising new technologies currently being developed; like Flash memory it retains information when powered off, but provides faster write speeds and better durability.

One of the problems so far has been storage density. Phase-Change Memory works by changing chalcogenide glass between crystalline and amorphous states; the chips containing these are still rather large, and up until now could not be easily stacked on top of each other. Numonyx and Intel claim to have solved this: Continue reading Intel and Numonyx improve phase-change memory
