I have a solution for this problem (slow when filled up) but it’s not a fix for a the actual ‘bug’.
Why did I put bug into brackets?
SSD’s become slower as they’re filled up. Depending on the firmware and controller, one is more sensitive to this issue as the other. Any SSD becomes faster when some of it’s space is left unpartitioned. Usually 12% (or ideally 25%).
Sandisk’s ReadyCache uses Sandisk’s own controller. It’s a very simple controller that has very low IOPS. It’s also used in the Sandisk Standard drives. These drives become so slow when filled up that they become almost unusable.
This is why Sandisk can’t fix this ‘bug’. Since it isn’t a bug but a hardware limitation. They advertise the drive as 32GB and can’t suddenly make it 25GB to fix this issue.
How to make it 25GB so you don’t have to empty it every once in a while:
- type “list disk” (note the drive number of the SSD)
- type “select disk n” (n = the drive number found above)
- type “clean”
- navigate to the ExpressCache directory by typing “cd C:\Program Files\Condusiv Technologies\ExpressCache”
- type “eccmd -partition n 25000” (n = the same number found above)
- open the ExpressCache software and enable caching. you’ll notice the the cache size is around 24.4GB
This way you lose some cache space but the ReadyCache will stay speedy. 24GB of cache space is still plenty.
