Petabyte-Class E2 SSDs Poised to Disrupt Warm Data Storage
- abracadaniel 1y agoIf the cost is low enough, that could be the death knell for HDDs. No mention of pricing specifics, but they mention competing on cost when taking into account power usage and reliability. So, it will likely be more than comparable enterprise HDDs. If they can capture that market share, I can’t imagine HDDs last much longer with whatever small consumer market remains.
- xhkkffbf 1y agoI've had glitching problems with long term cold storage with flash SSDs. They just start losing a bit here or a bit there when they're off for a long time. I have been results with HDD. Is there any reason to believe that these versions will be stable enough?
- timschmidt 1y ago> They just start losing a bit here or a bit there when they're off for a long time. Flash cells are capacitors. Like all capacitors they leak slowly over time. For long term storage on an SSD you should probably keep it powered and regularly scrub the filesystem like ZFS does.
- londons_explore 1y ago> when they're off for a long time Ssd design isn't suited to this. In fact, I believe future ssds will need to stay powered up 24x7 or lose the stored data. (Maybe allowing brief power downs of say up to 24h)
- baby_souffle 1y agoThe question isn't IF but WHEN. I suspect spinning rust is still going to be critical to long-term and small/medium scale archive applications for at least another 5 years. It may not be getting significantly denser but it's a well understood, reliable-ish and affordable technology. I don't expect to have an "all flash" NAS at home (~100TB) for another decade :(.
