Flash dead end is deferred by TLC and 3D

Comment The arrival of a flash dead-end is being delayed by two technologies, both involving the number three – three-level cell (TLC) flash and three-dimensional (3D) flash – with the combination promising much higher flash chip capacities. As ever with semi-conductor technology, users want more data in the same space and faster …

All the flash world needs is more TLC, suggests report

Triple-level cell (TLC) flash is heading towards being nearly half of all flash shipments. A report from DRAMeXchange says TLC NAND flash will account for nearly half of the total NAND flash output in the fourth 2015 quarter. DRAMeXchange_TLC_chart The report author, Sean Yang, says TLC NAND is shifting from memory card and …

No NAND's land: Flash will NOT take over the data centre

Comment NAND is not taking over the data centre. Estimates of shipped disk and SSD capacity out to 2018 shows that, while flash will continue to grow faster, disk capacity will still outstrip that of flash by eight to one four years from now. SSD_vs_HDD_ships_To_2018 Total SSD capacity shipped is falling more and more behind disk …

Glasgow boffins: We can now do it, Captain. We DO have the molecular storage power

If the number of electrons on flash storage is getting too few for reliability then use molecules for bit storage instead, and that's exactly what Glasgow uni boffins have gone and done it. Smarty-pants at the university Schools of Chemistry and Engineering, working with Rovira i Virgili University, Spain, have created …

Intel and Micron's 20nm, 128Gb NAND chip

Keep up with the fast-moving world of all-flash array storage

An all-flash networked array can do wonders in speeding up data accesses by applications running in connected servers. It is obviously best if the all-flash array is seamlessly integrated with your existing networked storage infrastructure. Suppliers of new integrated flash arrays say that getting the best use out of flash …

Toshiba unveils SSD: Claims hard-as-nails kit has the write stuff

Toshiba has tweaked the design of its PX02SS flash drive so it can sustain 30 full drive writes a day for five years through a 12gig SAS interface. This SSD is made from Tosh’s 24nm enterprise-class NAND (eNAND) and comes in 100GB, 200GB, 400GB and 800GB capacity points. The 30 drive writes/day stat applies to all models. It …

Flash biz and virtual database chum: Our tests show we bust spinning rust

A flash array speed merchant and database virtualisation firm have got together to run a benchmark that shows their disk array brethren eating their dust. Delphix takes a master database and makes virtual copies of it for whomever needs them, including accounting types, big organisations trying to control data spread, and …

Flash is dead ... but where are the tiers?

Storagebod Flash is dead: it's an interim technology with no future. But yet it continues to be a hot topic and technology. I suppose I ought to qualify that. Flash will be dead in the next five to 10 years and I’m talking about the use of flash in the data centre. Flash is the most significant improvement in storage performance since …
