SSD manufacturer Sabrent has updated its Rocket 4 lineup with a pair of new single-sided PCIe 4.0 SSDs with up to 2TB of capacity. The new Rocket 4 SSDs, which will replace the existing Rocket 4 that's being phased out, will only have NAND chips on one side of the drive for improved compatibility with mobile devices. These will compete with the best SSDs, and perhaps the best PS5 SSDs.
The updated Rocket 4 features the Phison E27T controller, a newer solution that provides for low power designs. It lacks DRAM, as the name implies, but this shouldn't be a major issue. We've seen good results with the Corsair MP600 Elite that uses the same controller and BiCS6 NAND. The new drives come in 1TB and 2TB models, starting at $99.99 and $199,99, respectively.
Both Rocket 4 models feature sequential read speeds of up to 7,400 MB/s and random read speeds of up to 1,000,000 IOPS. However, the 2TB is slightly faster in write performance, featuring up to 6,400MB/s in sequential write performance and 950,000 IOPS in random write speeds. The 1TB flavor is rated at up to 6,100MB/s in sequential writes, and 850,000 IOPS in random write speeds. Endurance is 600 TBW per 1TB capacity, so 600 TBW and 1,200 TBW for the two models.
