I've often wondered why no one offers a product that consists of DRAM with an integrated battery. Every portable device, when it goes into sleep mode, constitutes an existence proof that this could work. You could even integrate this with a regular SSD to provide persistence when the battery dies.
- sophacles 5y agoThis has existed in various forms through the years: https://en.wikipedia.org/wiki/RAM_drive https://en.wikipedia.org/wiki/RAM_drive (section: Dedicated hardware RAM drives) It's non-existence (or at least extreme difficulty to locate)for current gen tech suggests that it doesn't improve performance enough to be worth the tradeoffs, but I'm not an expert in that at all.
- pkaye 5y agoThey exist mostly for servers. The capacity is much smaller since DRAM is much more expensive. http://www.ddrdrive.com/ http://www.ddrdrive.com/

- dboreham 5y agoThis has been done for decades. For various reasons it hasn't become mainstream. Cost of DRAM is one of those reasons.
