ssd

We host VPSes for customers. Each customer VPS is given an LVM LV on a standard spindle hard disk. If the customer were to leave, we zero out this LV ensuring that their data does not leak over to another customers.

We are thinking of going with SSDs for our hosting business. Given that SSDs have the "wear levelling" technology, does that make zeroing pointless? Does this make this SSD idea unfeasable, given we can't allow customer data to leak over to another customer?

Thanks
