INTRODUCTION

   If you happen to be building an ultra high-end PC (based either on the Z590 or the X570 chipsets) chances are you will equip it with a 2nd generation PCIe Gen 4x4M.2 NVMe SSD. And why not right? With numbers surpassing 7000-6000MB/s in reads and writes respectively these drives are currently dominating the consumer market in terms of performance and that’s pretty much all what people need to choose them. Durability in many cases many not be the best for extremely heavy workloads (CHIA I’m looking at you) due to TLC NAND flash being used but that aside these are the best consumer drives around today and since many of you asked today I’ll be testing the Sabrent Rocket 4 Plus 4TB model.

   Sabrent is a leading American manufacturer of computer peripherals and accessories, bringing uniquely styled quality products to consumers worldwide. Sabrent’s commitment is to offer the latest technology and the highest quality consumer electronic products at an affordable cost to everyone. Since its founding, Sabrent has consistently delivered to market a full line of computer peripherals and accessories that incorporate style, quality and the latest technologies available.

   Just like the 2TB model (review here) the 4TB Rocket 4 Plus PCIe Gen 4x4 M.2 NVMe drive by Sabrent is based on the highly popular NVMe v1.4 compatible PS5018-E18 NAND flash controller by PHISON which sports a total of 8-channels together with 32-bit ARM Cortex R5 CPUs (dual-core for the E16 and tri-core for the E18) using their CoXProcessor technology. Sabrent has once again paired the Rocket 4 Plus 4TB M.2 NVMe with Micron’s 512Gb 96-layer 3D TLC NAND flash and DDR4 SDRAM at 1600MHz by SKhynix (4GB for the 4TB model). Getting deeper into the PS5018-E18 NAND flash controller it features the 4th Gen LDPC engine (low-density parity check) along with end-to-end data path protection, wear levelling, thermal throttling (70 degrees Celsius limit), TRIM, bad block management, dynamic range SLC cache and SmartECC (RAID ECC) and fully supports AES-256bit hardware encryption and TCG Opal 2.0 and Pyrite. Sabrent also covers the entire Rocket 4 Plus line with a 5-year limited warranty and as for endurance numbers it reports 700TBW for the 1TB model, 1400TBW for the 2TB model and 2800TBW for the 4TB model.
