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: www.recycle-more.co.uk

  • 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.

Silence is Golden

My 2 year old hybrid drive, a 750GB SSD/HDD started to fade, so I knew it was time to get a new drive. I checked around and liked what I read about the Samsung 840 EVO at 1TB.

I ordered one and in just 2 days I was ready to try my first true SSD. I restored my backup on to the SSD and I booted up Debian (wheeze) in just a few seconds. Everything is very responsive and fast. Next, I setup my two virtual machines with Windows 7 and Windows XP as guests. This is where the 840 EVO is really amazing. Booting my virtual machines only takes seconds, but they run so much fast than before. Even faster then when I dual booted Windows 7 with the old hybrid drive. The best part of using the SSD, there's no noise. You can hear a pin drop in my office now. One more thing. Remember to activate trim or fstrim in cron.daily and set swappiness to 0 and/or remove swap space. Likewise in your virtual Windows machines, turn off scheduled defragging and remove/set your paging to 0 bytes (no swap file).

This is my first SSD, and i figured I'd notice an improvement. Wow! I am blown away! I've only had it for a short time, so I can't speak to how hardythe unit might be, but it is surely the best thing I've done for my computer! It was easy to install, moving my OS and programs, etc.

from the old drive was practically effortless with the included software. It's a bit pricy, but i would surely buy another given half a chance.

Great Features - the best out there at this time

My first SSD - incorporated it into a new build - Have used WD VRaptors for years and really like the speed and reliability of them...................

However, I'm still in "shock & awe" with the performance of this SSD. Very easy to install - good instructions and great software.

Ideal Upgrade for older Laptop

I have an older i7 Laptop. Installing the Samsung EVO 840 TB SSD improved system performance and the temperature of the system is also much much cooler.

Samsung magician and copy software worked easily and only took a small bit of time to clone my original drive and upgrade to the new SSD. Excellent investment.
