Recycling Batteries Responsibly

  • The European Directive on Batteries and Accumulators aims to minimise the impact of batteries on the environment and encourage the recovery of the materials they contain. In the UK, regulations on the recycling of batteries and accumulators (rechargeable batteries) were Introduced in 2009. The Waste Batteries Regulations aim to significantly increase UK collection and recycling of used portable batteries from 3% in 2007 to 25% by 2012, rising to at least 45% in 2016.

  • The battery symbol on a product or on its packaging indicates that the product must not be disposed of with general household waste. Instead, it is the consumer’s responsibility to dispose of their waste batteries at a designated collection point so that they can be recycled. The separate collection and recycling of batteries at the time of dispo sal will help to conserve natural resources and ensure that they are recycled in a manner that protects human health and the environment. A comprehensive list of battery recycling centres can be obtained from:

  • All Samsung products that are subject to the Batteries Directive are compliant with the UK battery and accumulator Requirements. In accordance with national law, SAMSUNG Electronics (UK) Ltd is a member of an approved batteries producer compliance scheme. This scheme collects, treats and disposes of batteries on Samsung’s behalf.

Don't forget your SSD Settings!

When you install your SSD, fire up the Samsung Magician program that comes with it. For those of us who want to get the most out of our solid state drive, and want to make sure our computer settings aren't at variance with its capability, Magician will help tweak the settings in the SSD's favor.

For example, my Norton was optimizing my system, which meant defragging the drive, which is something you shouldn't do on an SSD. Also, it's nice to start up your computer, and have it all ready to go in about 30 seconds.

Samsung 840 EVO makes yet another breakthrough from when the 840 PRO stomped around. Even with TLC memory over MLC nand; on paper it looks pretty scary but in real world uses, in order to wear down TLC NAND a user would have to run the drive at 100% full load without stopping for 5 or 6 years straight which is near impossible unless the drive was being used in a server environment which will actually happen.

The drive over HM55 chipset was able to reach the expected and advertised SATA III speeds. However with RAPID mode turned on the drive exceeds expectation once again with speeds nearing 900MB/s read and just over 800MB/s writing which in turn mimics a RAID0 or PCI-E transfer speed. Over Intel Z77 chipset yields even higher speeds mainly due to the bus speed and the caching that happens across the board as HM55 was a notebook used to test. Overall this drive combines both shearing speeds and capacity into one package. Cost??? A drive that size, it's not bad as other drives of on the market do not reach 1TB and look like a 960GB type. I would recommend this to anyone that has a requirement of speed and storage in 1 package.

SSD Replacement

I replaced an old Kingston snv425 with the 840 EVO and even better performance, once I tried Rapid Mode and it exceeded its read & write specs.
