Macbook Air 13 inch (Early 2015) 1.6GHZ 8GB RAM | 256GB Flash Storage

Bought direct from Apple 3 years ago. I’ve had zero issues with it, or repairs.

It’s been in a case 100% of the time, so it’s in fantastic condition.

The laptop always had Kaspersky and/or Norton antivirus software on it. Although, I have since wiped everything and reset to its factory settings—ready for you to use!

There is a tiny scratch on the bottom-left of the screen (scratch, not crack), but its barely noticeable. Honestly. It’s as thin as a hair. (See zoomed-in photo).

Also, and I wasn’t going to point this out as it’s so small but wanted to be transparent—if you look at the back of the Mac (from the photo), there’s a tiny ‘dent’. Dent is an over-exaggeration, but I can’t find another word to describe it. It’s more like a spot. Located middle/top right.

Photos demonstrate the laptop booting up and working.

NAND flash manufacturers showcase new technologies

NAND flash manufacturers laid out their roadmaps for next-generation products and architectures at the 2018 Flash Memory Summit this month.

As expected, Intel, Micron, SK Hynix and Toshiba talked up 3D NAND flash chips that can store four bits of data per cell, known as quadruple-level cell (QLC). They also spotlighted their 96-layer 3D NAND and outlined roadmaps that extend to 128 layers and beyond to further boost density.

NAND flash manufacturers introduced new efforts to speed performance, raise density and lower costs. Toshiba launched a low-latency option called XL-Flash. Chinese startup Yangtze Memory Technologies Co. (YMTC) hopes to catch up to the flash chip incumbents with its “Xtacking” architecture that can potentially increase performance and bit density. And South Korea-based chipmaker SK Hynix harbors similar aspirations with its so-called “4D NAND” flash that industry experts say is a misnomer.

Key NAND flash manufacturer Samsung was notably absent from the Flash Memory Summit keynotes, a year after discussing its Z-NAND technology at the conference. Z-NAND is another attempt to reduce costs by shifting periphery logic to a place that doesn’t take up space on the flash chip, said Jim Handy, general director and semiconductor analyst at Objective Analysis.

Here are some of the new technologies that NAND flash manufacturers showcased at last week’s Flash Memory Summit:

Toshiba’s XL-Flash

Toshiba’s XL-Flash is based on the company’s single-level cell (SLC) 3D NAND bit column stacked (BiCS) technology and enables optimization for multi-level cell (MLC) flash. The XL stands for excellent latency, according to Shigeo (Jeff) Ohshima, a technology executive in SSD application engineering at Toshiba Memory Corporation.

Ohshima said XL-Flash requires no additional process and is fully compatible with conventional flash in terms of the command protocol and interface. The read latency of XL-Flash could be 10 times faster than conventional TLC flash devices, according to Ohshima.

He said the company has “a lot of room” to do more with its current 3D NAND BiCS flash technology before new nonvolatile memories such as resistive RAM (ReRAM), magnetoresistive RAM (MRAM), and phase change memory ramp up in volume and become dominant.

“So it ain’t over ’til it’s over,” Ohshima said.

Ohshima said a combination of XL-Flash and denser QLC flash could handle a broad range of application workloads and improve overall system performance over the classic storage architecture of DRAM and HDDs. He noted the performance gap between XL-Flash and QLC flash is considerably smaller than the differential between DRAM and HDDs. And, although XL-Flash is slower than DRAM, it costs less and offers higher capacity.

Industry analysts view Toshiba’s XL-Flash and Samsung’s Z-NAND as a low-latency, flash-based response to 3D XPoint memory technology that Intel and Micron co-developed. Intel last year began shipping 3D XPoint-based SSDs under the brand name Optane, and this year started sampling persistent memory modules that use the 3D XPoint technology. Micron has yet to release products based on 3D XPoint.

David Floyer, CTO and co-founder of Wikibon, said Toshiba’s XL-Flash and Samsung’s Z-NAND will never quite reach the performance of Optane SSDs, but they’ll get “pretty close” and won’t cost anywhere near as much.

Handy expects XL-Flash and Z-NAND to read data at a similar speed to Optane, but he said they “will still be plagued by the extraordinarily slow write cycle that NAND flash is stuck with because of quantum mechanics.”

Startup takes on incumbent NAND flash manufacturers

YMTC hopes to challenge established NAND flash manufacturers with Xtacking. YMTC claims the new architecture can improve efficiency and I/O speed, reduce die size and increase bit density, and shorten development time.

“It really takes courage to go down that path because we know that it’s not easy to make that technology work,” YMTC CEO Simon Yang said.

Unlike conventional NAND, Xtacking separates the processing between the flash cell array and the periphery circuitry, or logic, onto different wafers. The startup claimed the high-voltage transistors that conventional NAND typically uses for the periphery circuit limit NAND I/O speed. YMTC claims Xtacking permits the use of lower voltage transistors that can enable higher I/O and more advanced functions, according to YMTC.

“We really can match the DDR4 I/O speed without any limitation,” Yang said.

Yang said results have been encouraging. He said the flash chip yield is increasing, and the reliability of the memory bits through cycling looks positive. YMTC plans to introduce samples of the new Xtacking-based flash technology into the market early next year, Yang said.

“Hopefully, we can catch up with our friends and contribute to this industry,” Yang said.

YMTC started 3D NAND development in 2014 with a nine-layer test chip and later co-developed a 32-layer test chip with Spansion, which merged with Cypress Semiconductor. YMTC moved the chip into production late last year, but Yang said the company held back on volume ramp-up because the first-generation product was not cost competitive.

“We are very much profit-driven,” Yang said. He later added, “We only want to ramp into volume when it’s cost competitive.”

Handy expressed skepticism that YMTC will be able to meet its cost target, but he said YMTC’s Xtacking efforts might help the company to get to market faster.

SK Hynix 4D NAND flash

SK Hynix came up with a new name to describe its latest NAND flash technology. The company said its “4D NAND” puts the periphery circuitry under the charge-trap-flash-based 3D NAND cell array to reduce chip size, cut the number of process steps and lower overall cost over conventional NAND, in which the periphery circuitry is generally alongside the NAND cell.

But, industry analysts say 4D NAND is merely a catchy marketing term and the approach not unique.

“YMTC is stacking a chip on top of the other, whereas Hynix is putting the logic on the same bit but just building it underneath,” Handy said. “The cost of the chip is a function of how big the die is, and if you tuck things underneath other things, you make the die smaller. What Hynix is doing is a good thing, but I wouldn’t call it an innovation because of the fact that it’s the mainstream product for Intel and Micron.”

Intel and Micron have touted their CMOS under the array (CuA) technology in both their 64-layer QLC and 96-layer TLC flash technologies that they claim reduces die sizes and improves performance over competitive approaches. Handy said Samsung has also discussed putting the logic under the flash chip.

Hyun Ahn, senior vice president of NAND development and business strategy at SK Hynix, said his company’s charge-trap-based 4D NAND roadmap starts at 96 layers with a roadmap that extends to 128 layers and beyond using the same platform.

The first SK Hynix 4D NAND technology will begin sampling in the fourth quarter with 96 stacks of NAND cell, I/O speed of 1.2 Gbps per pin, and a mobile package of 11.5 by 12 mm. The chip size is 30% smaller, and 4D NAND can replace two 256 Gb chips with similar performance, according to SK Hynix.

The new SK Hynix 512 Gb triple-level cell (TLC) 4D NAND improves write performance by 30% and read performance by 25% over the company’s prior 72-stack TLC 3D NAND, with 150% greater power efficiency.

Upcoming 1 terabit (Tb) TLC 4D NAND that SK Hynix will sample in the first half of next year fits into a 16 mm by 20 mm ball grid array (BGA) package with a maximum 2 TB for BGA. An enterprise U.2 SSD using the technology will offer up to 64 TB of capacity, according to SK Hynix.

SK Hynix plans to begin sampling 96-stack QLC 4D NAND, with 1 Tb density in a mono die, in the second half of next year. The company said the QLC 4D NAND would provide more than 20% higher wafer capacity than the TLC NAND that it has been producing since the second half of last year. The 72-stack, enterprise-class 3D NAND will represent more than 50% of SK Hynix NAND production this year, the company said.

Vexata fires up NVMe flash storage to tackle analytics

NVMe flash storage vendor Vexata has rewired its ignition to enable faster cognition of dense analytics.

The startup last week upgraded its VX-OS operating system for capacity and performance. VX-OS 3.5 allows customers to expand a VX array nondisruptively from 180 TB to nearly half a petabyte in 6U.

Vexata is among a handful of startups with NVMe flash array storage systems designed from scratch for nonvolatile memory express flash technologies. Its cut-through architecture offloads the data path on field programmable gate arrays. Vexata arrays store metadata in DRAM, and Vexata’s internal Ethernet fabric parallelizes all data in the system for distributed shared storage. 

NVMe is viewed as a faster alternative to the SCSI protocol. Most established array vendors allow customers to replace SAS and SATA SSDs with NVMe flash drives, although the market for rack-scale flash systems is evolving.

The next phase of development is a fully developed ecosystem for the NVMe over Fabrics (NVMe-oF) specification. NVMe-oF enables NVMe message commands to be transferred between a host server and storage array via Ethernet, Fibre Channel or InfiniBand. Today, PCIe-connected NVMe drives require Remote Direct Memory Access for data transfer.

“We are targeting this (product) to cognitive computing, where we increasingly are finding a number of large opportunities. Customers want to talk about AI, machine learning

and
autonomous systems. These aren’t fringe applications. Organizations are mainstreaming this stuff,” Vexata CEO Zahid Hussain said.

VX-OS 3.5 was engineered for improved latency on mixed read-write random workloads. Hussain said Vexata storage now can ingest writes at about 1.5 TB per minute, bringing it closer in line with its 3 TB to 4 TB per minute ingest rate on reads.

Most vendors design their all-flash and hybrid arrays with a dedicated clutch of SSDs to cache hot data, plus either disk or flash as back-end storage. Caching speeds performance, but it also limits the size of the working data set. 

Hussain said using up all the NVMe SSDs provides storage for denser computations and can modify data as it is being read.

“The strategy before was to add more controllers, but that would only activate a smaller number of the total available SSDs in the array. We have GPU-

ified
the whole architecture to solve that problem,” Hussain said.

VX-100 NVMe blades double up on capacity

The first iteration of Vexata’s array hardware scaled capacity to 180 TB.  VX-OS 3.5 lets existing customers scale capacity up to 64 NVMe SSDs, without re-cabling. Each array can support 16 storage blades that connect directly into the Vexata Ethernet midplane.

The upgrade expands VX-100 arrays to 435 TB in 6U. The system does not use an SSD cache for acceleration or inline data reduction for capacity. All capacity in the system is presented as raw storage.

VX-100 arrays include 16 ports for 32 Gbps Fibre Channel, NVMe over Fibre Channel or NVMe over lossless Ethernet. Each storage blade consists of four SSDs and embedded processing for local scheduling and metadata operations. Vexata supports clones, erasure coding, data protection with RAID 5 and RAID 6 and thin provisioning.

Hussain said customers will be able to get 1 PB in the 6U form factor by the end of 2018 by swapping in 8 TB

SSDs
.

“Conventional arrays still use x86 controllers and I/O paths that slow down the performance,” said Tim Stammers, a senior storage analyst at 451 Research in New York City. “The key thing Vexata is doing is to streamline the SAN architecture to get the most performance possible out of the NVMe storage.”

Vexata chief marketing officer, Ashish Gupta, said customers gain about 4 GBs of throughput when a blade is added to the array.

“We’re giving you the ability to scale performance and capacity with a single blade addition,” Gupta said. “That means you can maintain your cost structure without increasing a whole bunch of controllers, stitching them together, with the operational and computational complexities that come with that.”

The VX-OS release adds a feature for managing multiple Vexata chassis with a single pane.

About two dozen customers are using Vexata’s NVMe flash storage in production, Hussain said. They include the University of Hawai’i’s Pacific Disaster Center, payroll processing outfit Tata Consultancy Services, and Oath Inc., the digital media subsidiary of Verizon Communications.

“They have managed to get some production deployments already,” Stammers said. “There are quite a few types of application for very fast purpose-designed NVMe storage. The market isn’t moving at a rapid pace at the moment, but there is demand [growing] for this type of extremely fast, purpose-designed NVMe storage.”

Adobe zero-day fix precedes June Patch Tuesday

An Adobe zero-day vulnerability in Flash Player that was actively exploited stirred up excitement for admins in the week leading up to June Patch Tuesday.

Adobe released a fix for the zero-day (CVE-2018-5002) and three other vulnerabilities for the Windows client operating system on June 7.

The zero-day exploit launched its attacks from Excel documents sent via email. Users who open these infected Excel attachments on unpatched systems could allow the execution of arbitrary code under the exploited user account.

Chris Goettl, director of product management, IvantiChris Goettl

After the Adobe zero-day issue, the patching workload for administrators is lighter than usual for June Patch Tuesday, with about 50 unique vulnerabilities to correct — including 11 rated critical.

“Our recommendation is the Flash patch — if it already hasn’t been pushed out, [give that] high priority,” said Chris Goettl, director of product management at Ivanti, based in South Jordan, Utah.

June Patch Tuesday closes about 50 vulnerabilities

Microsoft released an update for the only publicly disclosed vulnerability (CVE-2018-8267) for June Patch Tuesday, which affects the Microsoft scripting engine on all supported versions of Internet Explorer. Attacks can exploit this flaw through a compromised website, or user-contributed ads or content, to take control of the target machine.

On an unpatched system, attackers could execute arbitrary code as the hacked user. Organizations that follow least-privilege rules that restrict the use of higher full permissions will reduce the damage from a breach.

Jimmy Graham, director of product management at QualysJimmy Graham

Microsoft’s June Patch Tuesday fixes also closed a remote code execution vulnerability (CVE-2018-8225) that affects all supported versions of Windows. This vulnerability could allow an attacker to compromise systems through a domain name system (DNS) server.

“That would be higher risk for mobile workstations, where it’s likely the system will be accessing an untrusted DNS server through public Wi-Fi,” said Jimmy Graham, director of product management at Qualys, based in Redwood City, Calif.

A memory corruption vulnerability (CVE-2018-8229) in the Edge browser’s Chakra scripting engine would let an attacker exploit an unpatched system through specially crafted websites or user-provided content. The effects depend on the level of privilege on the system.

Spectre vulnerabilities continue

Just when it seemed the Meltdown and Spectre vulnerabilities were winding down, security researchers uncovered another CPU bug. The vulnerability, called Spectre variant 4, is similar to the other speculative execution side-channel vulnerabilities disclosed in January, but they are rated with moderate severity.  

Jann Horn, a security researcher at Google’s Project Zero, and Ken Johnson, of the Microsoft Security Response Center, discovered Spectre variant 4 (CVE-2018-3639). This exploit enables malicious actors to read privileged data across trust boundaries.

Microsoft released its ADV180012 advisory in January to assist administrators with closing the exploits from the speculative execution side-channel vulnerabilities. The company continues to update the site, and it added further mitigation instructions to address Spectre variant 4. There are still no active attacks on Meltdown or Spectre, but administrators should install the patches and microcode updates when the CPU manufacturers release them.
