The sustained write speed, however, wasn't quite matching the specified 6000MB/s, although typically this is expected behavior, especially at this storage density, which is why manufacturers tend to note an "up to xxxxMB/s" figure when stating both read and write speeds. Doing multiple runs, both read and write speeds remained consistent overall. I was impressed to see that the read speed kept up with the 2TB Rocket 4 Plus-G. Yet even so, sustained performance consistency was very good in multiple runs of the benchmarks below, as well as in heavy workload usage. To be safe, it is best to check the user manual for your particular board to see what slots can and cant be used in combination, as you may not atually be getting the full potential of your new NVMe SSD if these quirks are not looked into. If you have a Z790 board and use a Gen 5 SSD, then you may lose functionality of PCIe slots entirely. This is all assuming PCIe Gen 4 SSDs are being used. If some drives are not detected at all, then you may need to change the SATA or M.2 slot you've got a drive plugged into so the chipset can allocate the correct resources. If you are not sure what speed your drives are running at with everything connected, then simply checking the BIOS/UEFI under the drive details pages should show information on the speed/lanes utilised. On other boards such as Z790, this may well be different and you find yourself witth half the PCIe lanes that you would otherwise have, if connecting SATA drives in conjunction with the lower M.2 slots being occupied. On my Z690 board I am using the Samsung 8TBS ATA drive via USB 3.2 Gen 2 for this reason, as using a any of the lower bank of SATA ports disables those ports as the lower M.2 slots being used takes the priority. It is worth pointing out that on an Intel platform such as Z690/Z790, the M.2 slots that run off the chipset, not the CPU (the slot closest to the CPU), will share PCIe lanes with both GPU and SATA depending on how many SATA drives you have connected. This sits directly behind -and is completely blocked by- the RTX 4090, so heat soak is expected since no airflow gets to such a tight space given the size of a 4090 cooler as shown below. ![]() The drive was installed in the secondary bank of 3x M.2 slots on the motherboard which is covered by a large panel heatsink. Primary OS SSD: Sabrent Rocket 4 Plus-G 2TB. ![]() This will no doubt be a similar use-case scenario for the majority of people looking for a fast and reliable 8TB NVMe SSD in builds where a smaller capacity SSD is the primary OS drive, leaving a large capacity drive for everything else.Īll testing was conducted on the following build: I opted to long-term test the 8TB Rocket 4 Plus as an active workload and storage drive for a couple of months, focusing not only on game installs but also media and my Lightroom catalog, which currently sits at 2.35TB in size. Those with extremely large gaming libraries should be more than happy as time goes on and newer titles leverage the bandwidth that NVMe SSDs in general are capable of, with or without gaming technologies like DirectStorage.Īs the Rocket 4 Plus 8TB and Rocket 4 Plus-G 2TB are both PCIe Gen 4 SSDs, come from the same model family and share the same Phison E18 controller, this review will supplement the Plus-G review, and shed light on any key differences between both drives.
