OCZ is showing off some new goodies at Computex 2015 in the form of a completely new SSD model – the Trion:
The Trion is based on an in-house Toshiba ‘Alishan’ controller – the first internal design from that company. Since it is sourced from within Toshiba, the new SSD controller is to be tuned for consumer workloads and should employ lower power states than prior OCZ / Indilinx SSD controllers, as well as Toshiba’s own proprietary QSBC (Quadruple Swing-By Code) error correction technology, which should squeeze a bit more usable life out of the A19nm TLC flash. This is what QSBC looks like compared to competing BCH and LDPC technologies:
We suspect Toshiba dialed back the algorithm a bit for client usage, but it should still be far superior to BCH. We don’t have many more details as the Trion has not yet been officially launched, but we do have this shot of a round of benchmark results from a pre-production 960GB model:
From what we can see, it appears to be a good performer (by modern SATA 6Gb/sec SSD standards), but we naturally can't tell anything for sure until we get samples in for local testing, as we have no idea of the state of preconditioning of the Trion in those tests.
Also on display were the recently launched Z-Drive 6000 and 6300 Series parts:
These are OCZ’s enterprise-grade NVMe devices, available in 800GB, 1.6TB, and 3.2TB. The 6000 series is a 2.5” 15mm SFF-8639 device aimed at lighter workloads with a rating of 1 Drive Write Per Day (DWPD) over a 5-year period, while the 6300 series brings that figure up to 3 DWPD and offers an HHHL PCIe card as an optional form factor. The higher writes per day are facilitated by the move to A19nm eMLC flash.
We’ll be keeping a close eye on these new developments from OCZ and we are eager to get these in the shop for some thorough testing!
Press blast for the Trion and Z-Drive 6300 Series after the break!

At CES, we stopped by OCZ and were briefed on their new SSD controller, the JetExpress:
As indicated on the placard, the JetExpress supports M.2 PCIe 3.0 x4 (M.2 is typically PCIe 2.0), and natively supports both SATA and PCIe / NVMe connectivity.
I found out some more goodies about this new controller. Aside from being configurable during production to support SATA or PCIe, this is actually a 10 channel controller (SSDs are typically limited to 8 channels). The controller can support LDPC *in addition to* BCH error correction. This is important as LDPC requires more compute power and is slower than BCH, so OCZ is baking in the capability to use BCH early on, and transition over to LDPC as the flash wears to the point where BCH can no longer efficiently correct bad pages. This means the JetExpress should be able to maintain very high performance while extending flash life out with LDPC only when it's needed.
Above is the Vector 180, which is launching soon. We are under NDA on this product, but nothing is stopping you from checking out the pic of what they had displayed above :).
Here's the Z-Drive 6000, an SFF-8639 (PCIe 3.0 x4) 2.5" enterprise SSD. The PMC Sierra controller supports NVMe connectivity and power modes are switchable to enable even higher performance. Performance looks to be very competitive with the Intel P3700, rated at 3GB/sec reads and 2GB/sec writes, as well as 700,000 4k random read and 175,000 4k random write IOPS. Our next OCZ review should be of the Vector 180, but samples are not out yet, so stay tuned!
OCZ's press blast for the JetExpress launch appears after the break.
