Lastly, the drive comes with a standard 5-year warranty which is the preferred length of warranty for a premium drive. The original variant of this drive was only rated at 7000/5300 respectively, so the improvement in specifications is not trivial. Getting to those specs, the Rocket 4 Plus 1TB has all the rated performance of a top-end PCIe 4.0 SSD, with sequential reads at 7400 MB/s and writes at 6100 MB/s. The original version of the Rocket 4 Plus has not been in distribution for about half a year, so new purchases of the Rocket 4 Plus should all be the new version. If you own one of the Rocket 4 Plus drives and are curious as to which model you own, the Sabrent Control Panel application can help you identify your drive. While I am not a fan of changing drive components without issuing a new SKU, at least when Sabrent has done it here the specs are improving rather than getting worse, as well as acknowledging the change and updating the spec sheet. Right now on the Sabrent website for the Rocket 4 Plus the specs are for the original version of this drive and has not been updated yet I am told they are working on fixing that. This spec sheet has been updated for the 176-layer variant of the Sabrent Rocket 4 Plus. Sabrent Rocket 4 Plus 1TB Specs from Sabrent The Sabrent Rocket 4 Plus line of SSDs is available in sizes between 1TB and 8TB. The rear side of the drive has nothing except a label. This is a top-flight set of components and my performance expectations are very high for this drive. This is an identical setup to the Seagate FireCuda 530. ![]() The Sabrent Rocket 4 Plus bundles Micron 176-layer TLC NAND with the Phison PS5018-E18 controller. We will learn more about that in thermal testing. This front label is a thin metal heatspreader that can help keep the drive cool under a light load. The Sabrent Rocket 4 Plus 1TB comes in a single-sided M.2 2280 (80mm) form factor. For now, we will get to testing and see how the current Rocket 4 Plus 1TB performs. Another 2TB Rocket 4 Plus was sent over and we will look at that drive in a later article and perform a head-to-head comparison between the old and new drives. The second reason is that Sabrent has actually changed the NAND used in the Rocket 4 Plus since the initial release, and according to them performance has improved. This same reason is why we will soon be re-reviewing the Samsung 980 Pro 1TB, so stay tuned for that one. ![]() The first is that we have standardized on 1TB models for most of our performance testing and I wanted to be able to include the Rocket 4 Plus in our competitive graphs. We have previously reviewed the 2TB Rocket 4 Plus drive, but we are doing this review for two reasons. And the drive has 9% of the NAND set as over-provisioning space to optimize garbage collection.Today we are taking a look at the Sabrent Rocket 4 Plus 1TB NVMe SSD. Plus, it has end-to-end data protection to keep data safe and power management support for better efficiency.Īlso, the device's Kioxia’s BiCS4 96L TLC, which means our Rocket NVMe 4.0 sample is utilizing thirty-two 512Gbit NAND dies spread out into the four NAND packages on the PCB. It also supports thermal monitoring, TRIM, and the Format NVMe command to securely wipe data. Our 2TB sample features two 1GB SK Hynix chips for the task of FTL table mapping. It utilizes a DRAM caching architecture to maintain strong performance under heavy workloads. The main difference between the two is not only the PCIe Gen4 PHY but additionally, it boasts Phison’s updated 4th Gen LDPC ECC engine. ![]() Built on a 28nm process node and featuring dual Cortex R5 CPU cores with dual co-processors (dubbed CoXProcessor 2.0), the overall design is similar to the Phison’s E12. With class-leading endurance ratings, our sample is covered to withstand up to 3,600TB of writes within the warranty period.Īt the heart of the SSD is the Phison PS5016-E16 PCIe 4.0 x4 NVMe 1.3 SSD controller. While you have to manually register your Sabrent’s Rocket NVMe 4.0 for its full warranty, you shouldn’t ever have to worry about the device’s endurance. ![]()
