I guess normal RAM has pretty much infinite TBW compared to an SSD?
Some SATA SSDs have a cached mode where data gets put into normal RAM first, and then copied onto the SSD, but it's not really useful other than getting overinflated benchmarking numbers (things get messy if your system loses power before the data can transfer from RAM to the disk). Samsung calls it RAPID, the Crucial name is Momentum Cache
- tgflynn 4y agoYeah, but with the difference in price you'd have to need to replace your SSD monthly for DRAM to come out cheaper and I highly doubt you'd be writing data that fast.
- justinclift 4y agoSome of the enterprise grade SATA SSD's have a fairly long lifespan which might be suitable. eg: https://www.scorptec.com.au/product/hard-drives-&-ssds/solid-state-drives-(ssd)/85082-za4000nm1a002 https://www.scorptec.com.au/product/hard-drives-&-ssds/solid... That's a SATA drive rated for 5,600 TBW, and it's "maximum" rated write speed is 540MB/s. To work out how long the drive should last at that maximum speed, let's do: 540MB/s * 60 (seconds) * 60 (minutes) = 1,9444,000 MB per hour Let's call it 2 TB per hour for simplicity. We take the rated endurance of 5,600 TBW, and divide it by the above 2 TB/h, giving us "2,800" hours worth of write endurance. At 24 hours in a day, that's 116 2/3 days worth of endurance at the maximum write speed the whole time. Anyway, if the project in mind is going to run for less than ~120 days, it should be ok. Any other hardware/software issues aside that is.
