[一般問題] SSD 唔插電可以放幾耐

我有隻SSD 冇插電半年, D資料???

At 35 degrees it will lose data after 6 months.  Don't do that.

Cox found that for ever 5°C/9°F the temperature rises, the storage time halves.  In other words, if stored at 30°C/86°F your data is only expect to last for a year of unpowered storage.  And at 35°C/95°F the data will only last six months. - See more at: http://www.dailytech.com/Seagate ... thash.ta7Kviuf.dpuf

姐係35度可以放6個月

如果P/E用得少, 損耗少, 室溫下MLC可以放二年或以上都得, SLC可以再長d, 最短係TLC

My understanding is that AnandTech does not disprove what I said before.  It simply says when the SSD is powered (as in typical computer usage), one needs not worry about data retention.  It also makes the assumption "room temperature is below 30 degrees" - which is not suitable for Hong Kong summer without air conditioner.

OP's scenario is 冇插電.

it didn't. but your statement is just misleading.
The retentation is related to the ssd's wear level. The retentation period in your statement is true when the drive is already wear out. This is not the typical case for a client ssd.

And obviously the retentation peroid is also related to the endurance of the ssd.

    All in all, there is absolutely zero reason to worry about SSD data retention in typical client environment. Remember that the figures presented here are for a drive that has already passed its endurance rating, so for new drives the data retention is considerably higher, typically over ten years for MLC NAND based SSDs.

"typical client environment" means it is in use, not like the OP's scenario, because preceding its "typical client environment" it talks about "For active use the temperature has the opposite effect"
