Which storage is better?
Based on Durability and Reliability SSDs are more durable than HDDs. These are based on NAND flash memory and have no moving parts which makes it free from physical damage. These are useful for laptops and portable devices. SSDs are NOT a good option. An enterprise SSD is in spec if it holds the data for 30 days unpowered. A consumer SSD is 1 year unpowered. A spinning hard drive is much better as the bits on a HDD DO NOT significantly decay with age.If you want storage on a budget, you’ll have to switch over to an HDD, like the Seagate Portable. Still, we often find that in the tech world, if you want the best, it will cost you, and the SanDisk Extreme is the best external SSD that we’ve seen to date.
How to store water for 50 years?
Preparing Water for Storage Water stored in thoroughly clean plastic or glass containers can be chemically disinfected for long-term storage by treating each gallon with 4 to 5 drops of unscented liquid chlorine bleach (Clorox or Purex type bleaches, containing 4% to 6% sodium hypochlorite). When storing drinking water for extended periods, it’s vital to choose materials that prevent chemical leaching and contamination. Water storage tanks made from food-grade stainless steel or HDPE are ideal for this purpose.
