打算換底板打爆128GB RAM.

即係如斷電或hang機重啟的data未save落SSD的話的data會無晒?

The difference between primocache and primo ramdisk is there.  Please read.
https://www.romexsoftware.com/en ... -vs-primocache.html

Long story short, Primocache is designed to be used at volume level.
Example,
- Assign 32GB ram for use by Primocache
- Select C, D and E drive (or any physical / logical drive)
- enable defer-write time of xxxx seconds
- write operations (of C, D and E) will be directed to memory
- outstanding data will be flushed to disk after xxxx seconds

"disk caching是否可以完全取代ramdisk全部功能"
I would say, it's a kind of very advanced ramdisk software alternative.  And the setup is very simple.

你set defer-write time 1 hour,咁即係一個鐘之後自動寫入SSD?如果我唔想自動寫入SSD,要我save data先寫入另外罝設的HDD又應該點set?

所有ramdisk 都係, ram 唔係 hard disk, 斷電係唔save 野的. 突然斷電會更加咩都無.
所以好多ramdisk 都在shutdown 時將ramdisk 的野抄去hdd, 下次開機時recall 返出來要來「扮harddisk」. 呢D功能在ramdisk 入面set.

上面師兄話用來BT, 一般是只用來downlaod file, download 完係要手動放番去ssd. 唔suppose 放在ramdisk 一世.

如果你裝個game 在ramdisk, 7*24 唔熄機的話無問題.
會熄機的話, 一般都係裝在harddisk 入面玩, 唔關ramdisk 事.
高級D 玩法, 先在ssd 裝個game, 然後開機叫ramdisk 自己reload 呢D 資料, 即係你的hdd 和 ramdisk 會分別有同一隻game.
利申: 我未試過咁做.

"如果我唔想自動寫入SSD,要我save data先寫入另外罝設的HDD又應該點set?"
As it's a disk caching software, this kind of setup is not supported

The software is doing some kind of delay, to postpone the write-to-disk operation.  As such, repeating write operations will be occurred in memory during that "1-hr".  The data will only be written once when the time comes (in 1-hr).  This is exactly the case : "減低不必要寫入次數延長TLC SSD壽命"

死機同 SSD寫死好似冇乜關系吧. 有冇人真係試過寫死 ssd ?


ramdisk  其實要有幾大 size 先有用 ? 俾 game 用 除非 有 128G+ ram 唔係依加d game 咁大真係....
一般 ramdisk 有點用法 ? 做 temp folder ? swap file ?

買到 128GB ram 的錢用來買多隻 有 power lost protect SSD 用 raid 1 會唔會重好 ?

自動manage已經夠
唔洗搞咩ramdisk
