Multiple sampling
On the S3000 at least double multiple sampling is always set. From a multiple sampling of
3 you must add a supplement to the response time. The related supplement is dependent
on the basic response time and the multiple sampling.

External OSSDs
If you use the OSSDs on another device via EFI as external output signal switching devices
(for example with two S3000 connected together), the response time increases by 20 ms
in each case.
