Introducing a new breed of enthusiast storage, the OCZ RD400 NVM Express® M.2 solid state drive series, designed to propel high-end computing into a new realm of possibility. The OCZ RD400 PCIe Gen3 x4 outperforms SATA SSDs by over 4.5 times in sequential read (up to 2,600 MB/s), and over 3 times in sequential write performance (up to 1,600 MB/s) so your system won’t be deprived of the storage bandwidth your data-intensive workload requires. The OCZ RD400’s next generation NVMe interface provides a more responsive PC experience with shorter storage latency than that of today’s traditional hard disk drives and SATA SSDs. Along with high performance, the OCZ RD400 is designed for mobile, desktop, or workstation applications.

Game-changing Storage

TOSHIBA’s new OCZ RD400 SSD redefines high performance storage for enthusiasts and hardcore gamers that feel held back by commodity storage hardware. With over 200,000 IOPS @4KiB of random read performance at your beck and call, the OCZ RD400 will be your next high-end system.

Get in the PCI Express Lane

Why keep using an interface that was designed for hard disk drives? PCI Express revolutionizes flash storage for tomorrow’s high-speed computing age. The OCZ RD400 boosts bandwidth and puts your data in the fast lane leaving SATA SSDs in the dust.

NVMe Interface

Utilizing NVMe technology, the OCZ RD400 reduces latency in your system’s I/O path between the drive and your CPU, resulting in smooth and responsive performance.

Good Things Come in Small Packages

The OCZ RD400’s compact M.2 2280 form factor packs in high performance and up to 1024GB of storage capacity, enabling high-end desktop speeds to exist not only in your notebook, but directly on your motherboard without taking up a PCIe slot.

OCZ RD400 Media Reviews

Our user experience while running the RD400 as our OS disk is really as good as it gets. Even though the RD400 is OCZ’s first stab at a consumer-based NVMe SSD, the RD400 is a polished piece of hardware. All three drives we reviewed performed flawlessly in every aspect and we didn’t just test with empty secondary volumes, we installed Windows, drivers, and programs from scratch on each of the three drives we tested. – TweakTown

Looking back at the performance the OCZ RD400 has to offer during our grueling benchmarking sessions, it is without a doubt we can say it is one of the best consumer drives out on the market. The OCZ RD400 is so good we just had to give it out Editor’s Choice award! – The SSD Review

This revival of the RevoDrive product line shifts to a very speedy PCIe 3 x4 interface, and the Toshiba controller (lifted from their XG3) makes good use of the NVMe protocol. – PC Perspective

Overall the Toshiba OCZ RD400 512GB is an excellent drive with great performance, great pricing, a great warranty program, and now it’s even backed by the Toshiba name. – Custom PC Review

There’s absolutely no denying the fact that the Toshiba / OCZ collaboration is starting to bear some high performance fruit. The RD400 is among the fastest SSD’s we’ve tested to date. – Hardware Canucks

It might be fair to say that the Toshiba OCZ RD400 is a true pro-sumer SSD, as you get the best of both worlds. It’s blistering fast with both consumer and professional workloads. It’s very energy efficient when working. It also initializes the fastest of any of the NVMe SSDs that I have tested, and is the fastest to the Windows 10 desktop, if this is important to you. All in all, the Toshiba OCZ RD400 M.2 NVMe SSD is outstanding, so much so, that I have chosen to use the RD400 as my system drive. – Myce
