Results: Enterprise Workload Performance
Our next set of tests simulates different enterprise-oriented workloads, including database, file server, Web server, and workstation configurations.
The database workload (also categorized as transaction processing) involves purely random I/O. Its profile consists of 67% reads and 33% writes using 8 KB transfers.
The database profile normally rewards SSDs with strong random write performance. It puts the 845DC EVO near the bottom of the pack, though ahead of Intel's SSD DC S3500.
In the file server workload, which consists of 80% random reads of varying transfer sizes, the 845DC EVO narrows the gap. However, it still trails the drives offering better random write throughput.
The Web server workload (100% reads of varying transfer sizes) is more to the 845DC EVO's liking; the purely read-based test allows Samsung's latest to stretch its legs. Only SanDisk's SAS-based Optimus Eco tops it in this round of testing.
Finally, the workstation benchmark (80% reads, 80% random), which introduces write operations back into the mix, pulls the Samsung SSD back to the middle of the pack.
Overall, the 845DC EVO does really well in read-intensive applications. Once writes, even at a low percentage, are mixed in, Samsung succumbs to SSDs with better random write specifications.

So basicly it's the more durable version of the 840 evo much like opertons and xeons are to the FX and core i7 series.Reply
like we know now after the ssd endurance test samsung is the worst enterprise candidate.Reply

Yes, that's a fair analogy. Just like the Xeon E3-1275v3 is an i7-4770K, but with ECC support.
I've yet to see an SSD fail due to read/write endurance. I only see them fail when the controller gets bugged, which seems to happen all the time, especially on loss of power.Reply
I'm guessing this SSD doesn't have to new firmware code that extends life and speed.Reply
Another win for the EVO. This SSD modified for enterprise workloads makes it a good buy for webservers.Reply
Hopefully the price will go down after launch, and then I see this being the best choice of webhosts.
Cheaper and adequate for that workload.
Eh I'll keep my 840 EVO 250GBReply
"Even still, I wand to commend Samsung's execution." (last page 1st paragraph) I guess that is supposed to be want, unless Drew Riley has become a wizard now :DReply
Commending their execution would be a bit harsh, don't you think?Reply

I'm sure worse things were said about Samsung at WWDC '14 yesterday ;)
