ATTO is a timeless benchmark used to provide manufacturers with data used for marketing storage products.
Sequential read transfers max out at 1.650 GB/s. Sequential write transfers max out at 1.293 GB/s. Overall, this is the best sequential performance we've seen from any SATA based array.
Our 850 Pro arrays' sequential write performance closely mirrors the performance of our SanDisk Extreme Pro array.
The 850 Pro really shines in Sequential Read Performance. Whether it be a single drive, or a properly configured array, Samsung's revolutionary 850 Pro has the best sequential read performance of any SATA based SSD on the market today.
Anvil Storage Utilities
Version and / or Patch Used: RC6
Anvil's Storage Utilities is a storage benchmark designed to measure the storage performance of SSDs. The Standard Storage Benchmark performs a series of tests; you can run a full test, or just the read or write test, or you can run a single test, i.e. 4k QD16.
12,000 points is a new lab record for a three-drive array running on Windows 8.1. Our 850 Pro array delivers massive performance across the board. The only PCIe drive we've had in the lab that can exceed this performance is Intel's NVMe based DC P3700 PCIe SSD, and that drive will set you back about $2500.
To illustrate just how well our 850 Pro array is performing, let's compare it to the performance of G.Skill's newly launched, highly touted Phoenix Blade PCIe drive.
There is no comparison; our 850 Pro SATA based array demolishes the Phoenix PCIe drive. Most importantly, our 850 Pro array leaves it in the dust where it matters most to your OS: random, low QD write performance. Even properly configured two-drive arrays composed of SATA based SSD's running on RST ports will leave the Phoenix Blade, or any other consumer based PCIe drive, in the dust (in an OS environment).
This comparison also serves to illustrate why, as I pointed out earlier, reviewers that have stated the Phoenix Blade, or any other consumer based PCIe drive to date, can outperform an Intel based array in an OS environment are incorrect. Reviewers can only be making that statement because they apparently do not understand how to properly configure an Intel based array, or they are simply making an uneducated assumption - an assumption that should not be past as fact to the consumer.
The performance disparity only gets worse for (non-NVMe) consumer based PCIe drives in a workload environment where read/writes are occurring concurrently, because they simply do not have good low QD random performance. In most cases, current consumer based PCIe drives cannot even outperform a single hyper-class SATA based SSD in an OS environment. If you do not believe this is a fair comparison, keep in mind that the Phoenix Blade, Revo 350, Comay Blade, etc. are essentially four SSDs in one, attached via a bus with far more bandwidth than SATA has available.
Read IOPS through Queue Depth Scale
Our 850 Pro array leads the rest of our arrays at all queue depths, finishing with a whopping 190,000 IOPS at QD32.
Write IOPS through Queue Scale
Again, our 850 Pro array delivers the best performance of all the arrays on our chart, topping out at over 240,000 IOPS at QD4. Maximum write IOPS when running Windows 8.1 for all our arrays with the exception of our Toshiba Q Series Pro array is achieved at QD4. Our Q Series Pro array does not deliver good performance with most synthetic benchmarks; however, it delivers the goods in a massive way when we run workload simulations.
Version and / or Patch Used: 3.0 Technical Preview
CrystalDiskMark is disk benchmark software that allows us to benchmark 4k and 4k queue depths with accuracy.
Note: Crystal Disk Mark 3.0 Technical Preview was used for these tests since it offers the ability to measure native command queuing at QD4.
Our 850 Pro array is just destroying all of our synthetic benchmarks. This is the best overall CDM performance we've seen from any array running on Windows 8.1. Maximum random write performance is delivered at QD4, confirming what we saw with our Anvil's testing.
Breaking down read performance reveals that only our Intel 730 array can outperform our 850 Pro array in one category, QD32 read.
A write performance breakdown mirrors what we saw with read. Only our Intel 730 array is able to outperform our 850 Pro array, and that is again in a single category, QD32 write.
Version and / or Patch Used: 1.7.4739.38088
AS SSD determines the performance of Solid-State Drives (SSD). The tool contains four synthetic, as well as three practice tests. The synthetic tests are to determine the sequential and random read and write performance of the SSD.
Our last synthetic based benchmark tells exactly the same story, and that is Samsung's 850 Pro is a synthetic benchmark juggernaut. So far, V-NAND has dominated our planar-based arrays. Although, many times this does not carry through when it comes to our much more important workload simulations. Let's move on to our light usage model simulations, and see what our 850 Pro array can deliver.
