When we first heard of TLC flash for the datacenter we could not envision that it would be able to handle write-heavy workloads or provide sufficient endurance comparable to MLC. Man, were we wrong. Intel's 64-layer TLC flash has turned out to be game-changing. As we've seen it emerge in the consumer space, and now the enterprise space, we've been astounded at the performance it delivers. The performance delivered has us wondering if it could be the best TLC flash solution on the planet.
So far, we've noticed a pronounced pattern from 64-layer IMFT flash. It's the most cost-effective 64-layer flash, and at the same time, it delivers the best random read performance at low queue depths of any TLC flash we know of. If we were to pick two attributes we would most want to see from a flash solution; these two would be it.
Others have moved to replacement gate technology, but Intel has chosen to stick with proven floating gate technology for their 3D flash. So far, this is looking like a good strategy. Floating gate technology gives Intel 3D flash the industry's highest areal density available, and CMOS under array keeps the footprint compact - lending itself to a more efficient array. All this efficiency translates to lower cost for the end-user.
The DC P4510 employs Intel's newest controller. This new controller allows for far greater density than the 2TB maximum offered previously. Increased density translates to more TB per rack and less power required per TB of storage. Lower power consumption per TB of flash, along with greater density per rack, means that TCO is greatly reduced. Ultimately a low TCO is the overriding goal of any datacenter operation.
Throughout our testing, we took notice of the DC P4510's exceptional low queue depth performance. It is 2-4x better than any enterprise SSD we've tested to date. The importance of low queue performance in the enterprise space is becoming more apparent as time goes on. Purveyors of enterprise SSDs generally like to trumpet the performance of their products at unrealistic queue depths of 64 and beyond. The fact is, for most workloads, the operating region for enterprise SSDs is from QD1-9 with QD1-2 being the majority.
Our mixed workload tests show that because the DC P4510 performs so well at low queue depths, whether it be read or write, it can out easily outperform SSDs with higher read or write specifications. Intel's TLC-based DC P4510 costs less, performs much better and offers greater density than any enterprise SSD we've tested to date. This is why we are awarding Intel's DC P4510 our highest recommendation.
The DC P4510 is by far the best performing enterprise SSD we've tested to date and is well deserving of a TweakTown Editor's Choice Award.
