Who's who in SSD? - by Zsolt Kerekes, editor - January 2015

Greenliant Systems was founded in April 2010 - by former SST chairman and CEO, Bing Yeh.

Until recently Greenliant's technology focus has been low power miniature SSDs and other SSDs (SATA and PATA) aimed at the industrial SSD market.

In a surprising move Greenliant recently entered the enterprise SSD market with a range of NVMe PCIe SSDs - the G7100 Series - rated at 10 Drive Writes Per Day (DWPD) for 5 years.
selected Greenliant milestones - from SSD Market History.

In November 2010 - Greenliant Systems began sampling SATA compatible variants of its NANDrive GLS85LS which have upto 64GB capacity in a 14mm x 24mm x 1.85mm 145 BGA. Active-mode power consumption as low as 500mW and a deep power-down mode can reduce this to 10mW. The SSDs have content protection zones and designers can select areas of the storage to protect with fast erase.

In February 2012 - Greenliant Systems has started volume shipments of its industrial grade rugged SATA SLC SSDs on a chip (BGA - 14mm x 24mm x 1.95mm) - NANDrive GLS85LS - which have upto 8GB capacity, 70/60MB/s R/W, include zoneable password security and fast erase, and strong power fail data protection.

In June 2012 - Greenliant Systems announced it is sampling industrial temperature range e.MMC compatible SSDs on a chip with upto 128GB capacity.

In January 2015 - Greenliant Systems entered the enterprise PCIe SSD market.
Surviving SSD sudden power loss
Why should you care what happens in an SSD when the power goes down?

This important design feature - which barely rates a mention in most SSD datasheets and press releases - has a strong impact on SSD data integrity and operational reliability.

This article will help you understand why some SSDs which (work perfectly well in one type of application) might fail in others... even when the changes in the operational environment appear to be negligible.

In custom SSDs some circuits or processing steps can be removed entirely from the bill of materials due to knowing from the system environment that they aren't needed or that an equivalent function is being done elsewhere at the system level. This is contrast to a "similar" standard SSD design - where it wouldn't be prudent for the product manager to weaken those operating requirements - because standard SSDs have to cater for a wide range of possible customer deployments (set by industry expectations).

Greenliant promises 10 years availability of SLC
Editor:- September 17, 2013 - One of the pressures which has been driving embedded SSD designers towards the kind of elaborate controller technologies which enable MLC to operate over the full industrial temperature operating range has been the cost per terabyte - but another has been the open question of whether it will be realistically possible to guarantee sourcing SLC in the future at all - which is why some companies like Virtium have instead got product roadmaps which ensure that future design slots can be filled with identical footprint SSDs which will use whatever future variations of nand flash memory the future market is likely to offer.

That's in contrast to the decades old market practise of stockpiling old technology chips for use in legacy equipment designs which are assembled much later. These longevity assurance programs can get complicated and expensive - and I've even heard of recent cases where SSDs are emulating 1970s vintage floppy drives to keep some expensive machinery running.

There are risks involved in both these approaches (to SSD design socket continuity).

Anyway in a product launch announcement today Chen Tsai, senior VP, manufacturing operations - Greenliant Systems said that ""To address applications with long lifecycles - Greenliant's new SLC SATA NANDrive (industrial BGA form factor SSDs) will be available up to 10 years through Greenliant's Long-Term Availability program."

For those in the rugged and military SSD markets - this type of consideration about long term product availability is the usual way of doing business.

That's in stark contrast to the consumer and enterprise SSD markets - in which designers are more interested in the probability that they will be able to get superior (faster and higher capacity) products in future motherboard designs (so long as they are software and interface compatible) - rather than getting exact clones of the original devices to work in the unchanged original motherboards.
