Samsung Intros 15TB Enterprise SSD

Samsung pushes enterprise flash capacities further with the PM1633a, a 15TB SSD based on the 12Gb/s Serial Attached SCSI (SAS) interface.

First announced at the 2015 Flash Memory Summit, the PM1633a comes in the 2.5-inch form factor-- allowing customers to fit twice as many drives in a standard 19-inch 2U rack compared to an equivalent 3.5-inch drive.

Allowing for 15TB capacity is the stacking of 16 layers of 256Gb V-NAND memory chips, for a total of 512 chips in each drive. In turn, each 256Gb V-NAND chip stacks cell-arrays in 48 layer, an improvement over 2nd generation 32-layer 128Gb V-NAND.

LaCie Ups 5big Array Storage

LaCie announces an increase in capacity for the 5big professional workstation desktop storage arrays-- a move from 6TB to 8TB HDDs brings brings maximum capacity of 40TB.

The 5-slot 5big arrays feature dual-Thunderbolt 2 connectivity and hardware RAID, allowing support for 4K video workflows. Bandwidth reaches up to 11050MB/sec, while the enterprise-class HDDs offer speeds of up to 7200rpm. LaCie says such bandwidth is enough for Adobe Premiere or Final Cut Pro users working on multiple 4K video streams in real time.

Chinese Investor Exit Complicates WD SanDisk Buy

A wrench gets thrown in Western Digital's plans to buy SanDisk-- Chinese IT company Unisplendour Corporation Limited (Unis) scraps its $3.78 billion investment deal with WD.

Unis, a unit of Tsinghua Holdings, dropped plans to buy a 15% stake in WD after the US Committee on Foreign Investment (CFIUS) announced an investigation of the deal. The decision triggered a 15-day period where either side could end the transaction... and that's exactly what the Chinese company did.

WD hopes to be still able to buy SanDisk, but the lack of Unis investment demands a change in asking price. Whereas it originally offered $19bn in cash and stock, WD is now asking shareholders to consider selling for $15.8bn.

Intel SSDs Getting Capacity, Speed Boost?

Micron starts volume shipments of 3D NAND chips-- meaning SSD storage products from both Micron and Intel might soon get a boost in capacity, performance and energy efficiency.

Current Intel consumers SSDs offer maximum capacity of 4TB, but Micron 3D NAND should allow 2.5-inch storage devices to "more than 10TB." Meanwhile portable stick-style storage devices should also get a capacity boost, specifically up to 3.5TB.

In addition 3D NAND promises "significantly higher read/write bandwidth and I/O speeds, as well as improved random read performance," together with a sleep mode able to cut power to inactive NAND even when other chips in the same die are active.

Eternal Storage, Via 5D Glass

Eternal Storage, Via 5D Glass

The hand in the picture might look like it is holding a simple engraved glass disc, but what it actually shows is a device able to store up to 360TB of "five dimensional" data.

Developed by University of Southampton researchers, 5D data is stored in 5 dimensions-- height, width, depth and two other dimensions produced by glass nanostructuring. Writing data on the glass requires a femtosecond laser able to emit incredibly short (280 femtoseconds, or 280 quadrillionths of a second) optical pulses. In turn the laser burns three layers of nanoscale dots on the glass.
