But the 1.6TB enterprise drive is well over $5,000, while this high-capacity, high performance drive is just $1,030. It shares the basic core silicon with its pro-class brethren, the P3700, so it’s got similar levels of performance. There’s a little bit of the Titan X about the SSD 750. The SSD makers who will follow up with inevitably cheaper NVMebased SSDs won’t have that R&D cost. Intel has had to invest heavily in the ecosystem of NVMe, working to ensure all mobo makers are able to get BIOS support for their Z97 and X99 boards. This is like the Extreme Edition CPU of solid-state drives.īut there’s a certain justification. Couple that with the fact it’s Intel, and prices were always going to be sky-high. That’s especially true given there’s still no NVMe competition. The problem with being a brand new technology, and being first to market, is that it will always command a high price tag. The 750 is the fastest SSD we’ve ever tested, and by a comfortable margin. Its 4K write performance is a quarter of what the SSD 750 can achieve. Compare all that with the fastest PCIe drive we’ve previously tested, the Samsung XP941, and you can see where the AHCI protocol is holding things back. At 38MB/s, the 4K random read speed isn’t amazing, but the write performance of 200MB/s is stunning, nearly twice as quick as the closest competing drive. There are some interesting scores when we get to the 4K random read/write performance. We’re shifting from talking in MB/s here… The scores on the harder AS SSD benchmark were lower, but 2.1GB/s and 1.2GB/s respectively isn’t bad. The reads were almost 2.7GB/s and the writes were 1.3GB/s. Its top speed? The peak sequential numbers from ATTO are unprecedented. That controller is kept honest with a hefty 2GB of DDR3 cache on this 1.2TB version. The bespoke controller at the heart of the P3700 is the same 18-channel controller as the one that makes the SSD 750 so speedy. It also forms the basis of this first consumer NVMe drive. That enterprise drive is important, not just for providing an example of how powerful the NVMe protocol can be. With the streamlined NVMe Linux stack, that’s cut by around a third, needing only 10,000 CPU cycles to reach the magic million figure. Using a quad-core i5, the Linux stack runs to 27,000 CPU cycles, meaning it needs a full 10 Sandy Bridge-level cores to drive one million IOPS (input/ouput operations per second). When Intel introduced its enterprise level DC P3700 NVMe drives, it used the Linux AHCI stack as an example of the wasted time and power that goes into running an SSD across the legacy protocol. The drive then has to go through each legacy command, even if they have no relevance to high-speed SSDs. These PCIe slots are wired to PCIe lanes from the CPU to support SLI and CROSSFIRE PCIe Gen 3.0 operation.That setup still works fine for mechanical drives, but the legacy commands in AHCI still have to be run through, even when an SSD is in place. For both X99 or Z97 this will ensure you can have the drive operate at full bandwidth. If a PCIe slot is used that is not PCIe Gen 3 you will still benefit from a wide range of the architectural and performance benefits but you will have considerably limited the maximum sequential performance of the SSD.Īs such it is recommend you use the secondary psychical x16 slot on a motherboard. THIS IS THE ONLY WAY TO ENSURE THE SSD’s FULL PERFORMANCE. It really tees me off that I cannot dedicate a x16 slot of ASUS's flagship MOBO to the PCIE NVMe Intel 750 Series add-in card so it can operate at its optimum level while also having just a 2-way SLI:īeyond that while the Intel 750 series SSD will operate in any x4 PCIe slot you want to ENSURE that a PCIe Gen 3 slot is utilized. The following two paragraphs of the below-linked article have severely bothered me for the past month. What am I misunderstanding, doing wrong or need to change? Read speed seems to be reaching a soft cap. The ATTO disk benchmark shows the same thing. Test : 500 MiB (x5) įrom reviews and screenshots, the sequential read should be closer to 2,500 MB/s.
