Storage across all platforms has been upgraded to faster and more energy-efficient SSDs

SSDs – the basics I’ll be brief here .... In an SSD, data is stored in microchips instead of magnetic disks, making them faster than traditional Hard Disk Drives (HDDs). SSDs are more expensive, but higher performance, draw less energy and can be more reliable. The SSD we use for hosting: the Samsung PM897. Why Samsung SSD? Samsung are a global brand with a strong reputation for high standards. They have a legacy of producing high quality products that goes back to 1938. Could we have bought less expensive SSDs? The quick answer is: yes! Other web hosting companies use cheaper SSDs, and to be fair to them, they’re generally perform OK for hosting. Note the ‘generally’ there. The computer storage market is a good example of getting what you pay for. Even though our storage has multiple levels of redundancy, we don’t want our SSDs to have any issues, ever. We don’t cut corners. We also want our storage to be as fast as possible without sacrificing reliability. Some of the less well-known (and less expensive) brands of SSD do have quality issues. Securing your data The PM897 includes hardware encryption management to the Trusted Computing Group OPAL 2.0 standard. This 256-bit encryption makes it difficult for your data to be accessed by hackers. Also, while our data centres already have multiple levels of redundancy to protect against power loss (like backup generators), our SSDs also have their own protection. An unexpected power outage – however unlikely – can cause problems. Data that’s stored in an SSD’s DRAM buffers can be lost forever. The DRAM is volatile, like the RAM on your PC or phone. Samsung’s Power Loss Protection (PLP) architecture protects against this by reacting to a power dropout. It uses the stored power in its PLP capacitors to write that buffered DRAM data to flash memory, right away. The SSD’s flash memory isn’t volatile, so there’s no loss of data, even in the worse of scenarios.
