While synthetic workloads do a great job of testing the underlying technology and reporting easy to understand results, they aren’t always indicative of how the drive will be used by the end user. Workloads that simulate enterprise environments try to bridge that gap without being overly complex.
The database profile is 8K transfers, and 67% percent of operations are reads.
The database profile shows us the individual attributes of the three drives we are looking at. At a queue depth of 1, the P3700 has a slight advantage, due to its superior low queue depth write performance. From there the overwhelming write advantage of the HGST drives take over. Finally, the P420m take the lead at high queue depths due to its read performance.
The fileserver profile is based on an 80% read/20% write mix. Its made up of blocksizes from 512 to 64K, each making up a different percentage of the access pattern. The pattern is: 512 bytes=10%, 1k=5%,2k=5%, 4k=60%, 8k=2%, 16k=4%, 32k=4%, 64k=10%.
The P3700 led most of the way in our fileserver test. Its class leading sequential write performance is enough to hold off the sequential read performance of the P420m.
The webserver profile is similar to the fileserver profile, but has some additional 128K and 512K accesses thrown in for good measure. Additionally, the profile is 100% read.
The P3700 and P420m were neck and neck at lower queue depths in our webserver tests. Once the queue depths got higher, the P420m pulled away.
Overall, the P3700 performed much like we expected. While it was not able to best the competition at every mark, it was competitive throughout.
REPORT ANALYSIS AND FINAL THOUGHTS
With the release of the P3700, and also the P3500 and P3600, Intel has made a huge splash in the NVMe market. Intel, once again, is showing their technical leadership. This line of products is made up of things both old and new. They have taken a huge step forward with their 18-channel, PCIe flash controller. This is the type of long-term investment that we can see them leveraging for many years to come. Intel went with the same tried and true NAND technology that has succeeded so well in the S3500 and S3700 SATA SSDs. When it all comes together, you have a wonderful enterprise device that can serve a multitude of needs.
When you look at the results, the P3700 didn’t produce crazy, unheard of performance. Yes, it did perform extremely well in certain tests. It required an extremely low amount of CPU overhead along with other tangible benefits. But there were two things that might make you wonder if this is just an enterprise drive.
The first is the excellent low queue depth performance. While enterprise environments are able to throw a large number of IOs at an SSD, consumer applications are normally limited to much lower queue depths. In fact, many traces we have seen show that consumer applications typically generate 4 or fewer simultaneous IOs. Many times, people see these outrageously high enterprise results and think it will speed up their computer at home, but because they are skewed to high queue depths, the performance increase would likely not be realized. The P3700, on the other hand, should perform really well in a workstation or enthusiast environment.
Finally, what makes the P3700 great is the price. At $3/GB, it may seem really high, but for a drive with 10 DWPD write endurance, this is a good price. For an NVMe/PCIe SSD, that price is amazing. We have said this many times in the past, you pay for for write performance and write endurance, end of story. What we are more excited about is the P3500 series. While this device has lower write endurance and write performance, it should still be an amazing drive for enthusiasts. At $599 for a 400GB SSD, it might seem like a lot of money, but enthusiasts will look at their dual GPU setup and think its a bargain.
Before we claim this to be the best consumer PCIe SSD on the market, we have a few more tests to run. Stay tuned later in the week to see how this drive performs under more consumer workloads.
As of now, it is still an enterprise drive. In our opinion, with pricing where it is, the Intel SSD DC P3700 is the best value in enterprise storage. Sure, you can get better performance in certain areas, from other drives, but it will cost you a premium. Intel has brought speed, performance, endurance and NVMe technology to the mainstream.
Since you say that you will test later on with consumer workloads,it would be nice to see an ANVIL and AS-SSD to see what is this device able to do compared to our normal everyday 2.5″ SSD’s
This is just a taste posted on our Forums yesterday…but yes the testing will follow our typical consumer testing…and then some…
Looking great!!!! Thanx!!!!
very impressive thnx
Try and sweet talk Intel into giving you a P3500 to review.
Why do you change the meaning of colors on graphs (iops against other drives)? It’s rather annoying.
It’s looking like PCI-E SSDs may hit mainstream in a few years, especially if the price goes down.
The question is, how big is the market for this type of SSD versus say, an M.2 drive? Hopefully we’ll see more entrants come in.
Well really…. how long before we see M.2 NVMe?
Nice Review! looking forward to the consumer workloads tests
maybe one of these in my Music /workstation computer and a 3500 for the gaming machine
Is it bootable?
Sure is…with Windows 8. I have tested it on the Asus H871 Plus, ASRock Z97 Extreme 6 and Z87 Extreme 11ac. My thoughts are that it is bootable with ANY newer motherboard that allows one to switch to URFI boot rather than legacy. I will cover this in the consumer review.
Is Intel actually doing RAID 0 on this board or is RAID now obsolete for the PCIe SSDs?
Negative….straight controller…single PCB…no RAID solution…it is pretty sweet.
You guys are taking away the meat and gravy of my consumer side of the report!
So in a VMWare host, say, would you rely on Intel’s “End-to-End” data protection & backups and not worry about raid / drive failures?
Sorry if I missed this in the article, but what is the USA/North America release date for this new NVMe drive from Intel? I am building a new enthusiast pc rig and have contemplated splashing out for one. Also, I am going to be using a mix of M.2, sata ssds (Samsung 850 Pros) and maybe one of these Intel P series NVMe drives. I wanted to get an LSI RAID card (12gb/s) and run RAID 5. What setting RAID setting would you recommend?
Hey, quick question: what software was used to run the SNIA tests?
