Keep your voice down in the data centre, the HDDs have ears! I SAID, KEEP...

It must be one of the worst ways to build a microphone imaginable, tapping into a disk drive's nanosecond head stops as it waits for the vibrations caused by sound to cease, but it has been done.

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 …

Data centre disk use is spinning down – Wikibon report

Decades of disk domination are coming to a close: Wikibon sees flash replacing disk entirely for primary data storage enterprise and hyper-scale cloud data centres over the next ten years. Disk will still be used as the cheapest and fastest – for the price – bulk-capacity media for archival and other low-access rate data. The …

Will flash save the data centre? Don't spread your wings yet, Vultan

Analysis The all-flash data centre: does it exist? Will it ever? Can we really imagine a data centre with no spinning disks and all the executing apps relying on solid-state storage? Such is the vision put forward by Violin Memory in its "Disk is Dead" campaign. But is this the future of the data centre? Violin chief marketeer Amy …

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.

Flash could be CHEAPER than SAS DISK? Come off it, NetApp

A NetApp pitch at the Flash Memory Summit said the cost-per-GB price trends for cheap TLC flash mean it will dip below SAS disks in 2017. TLC is triple-level cell flash which holds three bits per cell, half as much again as the standard 2-bit or MLC NAND that is used in SSDs and server flash cards. Because TLC is denser in …
