1. EVO is up to 40% Cheaper than PRO
2. EVO is only 2% slower than PRO
3. EVO is supposedly less durable than the PRO
4. But EVO has the same 5 years warranty as the PRO
5. PRO is often for enterprise uses. EVO is often for consumers.
In technical reviews the Pro and EVO kept trading places for top honors in different benchmarks. The EVO can hold its own against the Pro. The reason for that is Samsung released the EVO after the Pro. The EVO has a newer controller and firmware. Both models use the same 3D V-Nand flash memory.
Both models have excellent track records. Absolutely no problems, issues, glitches, or hiccups. Just about all of the problems I see in the forums for ssd’s in general are either due to a user’s lack of ssd knowledge, incorrect BIOS and/or system settings, and unsuccessful attempts to clone an existing drive to a new ssd. The biggest problem is with the cloning applications. That’s one reason why a fresh clean installation of the operating system is the preferred method. The other reason is that Windows does not do a very good job of deleting old, useless files and registry entries. No point in cloning all that useless data to a new ssd.
When Samsung originally released the Pro it came with a 5 year warranty. Then Plextor released an ssd with a 10 year warranty. Plextor advertising claimed 1.5 million hours MTBF. Samsung immediately increased the Pro warranty to 10 years to match Plextor. If it hadn’t been for Plextor, the Pro would still have a 5 year warranty just like the EVO. There are no other consumer ssd’s with 10 year warranties.
The usual suite of synthetic benchmarks can be deceving to anyone who is not familiar with them. The first and biggest problem is the benchmarks are designed to grossly exaggerate very minor performance differences between models. The graphs and charts in the technical reviews reflect those minor differences. To the uninformed those colorful charts make it appear as if there are very large differences when in fact the differences are almost negligible.
Typically an EVO model costs less than a Pro model and represents a better value for the money. However, there may be special sales coming up with decent discounts on the Pro too.
Most consumers would not be able to notice or “feel” any performance difference between the Pro and EVO. Someone would have to be doing some sort of professional work that involves a really heavy workload. Gaming and editing family videos do not count as heavy loads.
