Dell r710 with Esxi 5.0 on RAID 5 of SSDs

Last Modified: 2016-12-08
We recently purchased a dell r710.
In order to get the price point acceptable we had to purchase drives from a 3rd party.
I purchased 4 Samsung 256GB SSDs and set up in a raid 5 array.
I then installed vmware esxi 5.0 on a flash drive and created a datastore on the Raid 5 array of SSDs.
I migrated all our hosts to the new server and have not had any issues.
The datastore has just over 15% free space.
I am afraid I did not do enough research as I am now seeing that there is an issue with SSDs where free space may not be cleared correctly because of the lack of a “trim” function.  The drives support it but it sounds like the controller (Perc h700) and hypervisor (esxi 5.0) do not.  Additionally the hosts that are running on it are 2 Windows server 2003 x32 and 1 x64
Should I be concerned about the SSDs failing or having issues?
Is there any special configuration or considerations I should be aware of regarding this setup?
