When you see that a solid-state drive (SSD) can offer 4.5x the speed of a traditional hard drive, as the Toshiba OCZ RD400 512GB does, you sit up and take notice.

In contrast to standard SSDs and modern HDDs, the Toshiba OCZ RD400 512GB can be plugged into either a PCIe or M.2 port on your motherboard. Most modern desktop and laptop motherboards have these ports, so unless you have very antiquated hardware, you should be able to install the Toshiba OCZ RD400 512GB without any problems.

As SATA III ports were designed for traditional hard drives, SSD performance increases are hampered by the connection, which is why most modern SSDs peak at around 520MB/s write and 560MB/s read. This is comparable to the Toshiba OCZ RD400 512GB, which avoids the SATA ports and has speeds of 2,600 MB/s read and 1,600 MB/s write. It’s a big difference.

As a result, this performance will cost you more money. The Toshiba OCZ RD400 512GB costs £315 (around $385, AU$500), which is around the same price as Kingston’s SSDNow KC400, which costs £320 (around $400, AU$520). Price is similar, but capacity is half. For sequential write tasks, it’s about over three times the speed, and for sequential read tasks, it’s about over five times the speed.

This SSD is aimed at enthusiasts who value speed above all else. This is not the drive for those looking to store photos or add to a NAS.

 Features and specification

Toshiba OCZ

Toshiba OCZ RD400 512GB uses the M.2 interface on your motherboard, bypassing the aging SATA III ports used by standard HDDs and SSDs.  You can also plug in the Toshiba OCZ RD400 512GB with a PCI-E adaptor if you don’t have a motherboard with an M.2 connection (although most modern motherboards should have one).

In addition, the NVMe interface reduces latency in the I/O path between the drive and your machine’s CPU, making this a potentially very fast drive.

Toshiba’s RD400 512GB has a power consumption of 6.0W, which makes it a very efficient SSD. The Toshiba RD400 512GB has a service life of 296TB (the 1TB model has a service life of 592TB). With a mean time between failures of 1.5 million hours and SMART support, we can be confident this is a reliable SSD that can be used every day for intensive tasks.

Performance

Toshiba OCZ

In order to fully test the Toshiba OCZ RD400 512GB, we installed it in the M.2 port of an Intel Maximus VIII Extreme Z170 motherboard with the latest UEFI BIOS installed, Windows 10, and the Intel NVMe driver installed.

To find out how well the Toshiba OCZ RD400 512GB performed under pressure, we ran a number of benchmarks. According to our sequential tests using CrystalDiskMark, the drive hit reading and writing speeds of 2606MB/s and 1444MB/s, respectively.

The Kingston SSDNow KC400, which hit 560.8MB/s read and 536.6MB/s write speeds, boasts similar speeds. It would be fairer to compare it with Samsung’s NVMe SSD 960 Pro M.2, which uses the same M.2 connection.

The Samsung beat the Toshiba OCZ, achieving remarkable speeds of 3480MB/s read and 2100MB/s write – quite a difference, though the Samsung is more expensive ($329.99, £270, AU$430 for the 512GB version).

Even so, the Toshiba OCZ RD400 512GB represents a major leap in performance over SATA III drives, though if you’re already spending that much on an M.2 drive, you may think it’s worth it to upgrade to the faster Samsung.

With a top speed of 2670MB/s read and 1600MB/s write, the ATTO benchmark also provided some very impressive results, with a reliable tool for testing the read and write speeds of hard drives.

This Toshiba OCZ RD400 512GB SSD uses the M.2 port and really demonstrates the limitations of the aging SATA III interface.

The Toshiba OCZ RD400 512GB produced amazing speeds around two or three times faster than regular SSDs (and even more impressive speeds than traditional HDDs).

It’s not the fastest SSD (that honor currently goes to the Samsung NVMe SSD 960 Pro M.2), but as a (slightly less) expensive way to get into the world of M.2 SSDs, it’s certainly appealing.

Pros Cons
Range of sizes Not the fastest SSD out there
No SATA bottleneck Not suitable for all users
PCI adaptor included Expensive
Very fast

Conclusions

Toshiba OCZ RD400 512GB is an extremely fast SSD only outpaced by Samsung NVMe SSD 960 Pro M.2. It shows just how much potential M.2 SSDs have over SATA III; this is not only an incremental improvement but a significant one. Nevertheless, this upgrade isn’t for everyone since it comes with a huge price tag.

This drive offers some flexibility, and the price difference over the Samsung could make it a worthwhile purchase if you’re looking to give your storage a (serious) boost.
