Enterprise grade and consumer grade - there are pretty big differences in HDDs, but for SSDs, I feel that the changes are more based on software features and overall design.

In general, an enterprise grade SSD will:

1) have more software/firmware based features (encryption, management, etc)
2) have a much higher overprovisioning ratio. This means it might be listed as a 500GB drive, while actually having 1TB of actual flash. The other half is 'invisible' and as the blocks wear out, it has a much higher pool of spare flash to remap to allowing the drive to last much longer. A 500GB consumer drive on the other hand might only have 512GB flash - giving it a much smaller spare area.
3) They also might use a slightly better brand of...

It depends on the ssd. If the specs say it has a better read and write speed it probably will. But for the most part yes, redundancy in say raid 0 i wanna say, Where you have multiple hard drives holding one information or back ups. Constant reading and writing like in a server can wear down cells pretty quickly so you'd want an industry grade drive that's spec'd for it. Generally they should have at least 5 year warranties as well.

3) They also might use a slightly better brand of flash with slightly better endurance. It could also use SLC flash which has a much higher PE count.

That being said, the infamous six ssd torture test shows that even consumer drives have a lot of endurance above what they're rated for. It's unlikely that you'll ever wear one out.

I have a webserver which is running a Crucial M4 64GB as the OS drive, and a pair of 256GB Crucial MX100's as data drives (one as a main data drive, the other is a data mirror which gets synced a few times a day). The webserver has been up for several years, and the M4 is the original drive I put in. I checked the smartctl (it's running CentOS) and here's the nitty gritty:

power on hours 32895 (3.75 years)
power cycle counts: 79
reallocated sectors: 0
pending sectors: 0
uncorrectable sectors: 0

Crucial makes some darn good drives though. As for yours, from what I can find it uses a Sandforce controller, and Toshiba 19nm toggle NAND which is good. They do use quality parts (apart from any quibbles about OCZ and their firmware issues) - so I would expect that it should be just fine.

What I would do if you're concerned is install a SMART monitor to keep an eye on your drive. If it starts having problems, they'll show in the SMART codes and you'll be able to be a little more proactive in keeping the data safe vs just waking up one morning to a dead SSD. Acronis Drive Monitor is good, and free... there are others as well.
