Phison 1 TB ESR01TBTCCZ-27J

ESR01TBTCCZ-27J

The Phison ESR01TBTCCZ-27J-2MS is a 1-terabyte PCIe 4 NVMe SSD. As is often the case with SSDs, this model gets no mention on the official Phison website, so Notebookcheck has no clear understanding of when this 22 by 80 storage solution launched - presumably, it's early 2025 - or what its specifications are.

Performance

The ESR01TBTCCZ-27J is your standard lower-mid-range 2025 SSD, with sequential reads of ~4.43 GB/s and writes of around 2.33 GB/s, as tested with AS SSD 2. Its performance sustainability seems good with no significant drops spotted.

Nearly 20 hours of battery life with Panther Lake - MSI Prestige 14 Flip AI+ Convertible review

With the Prestige 14 Flip AI+, MSI introduces a compact 14-inch convertible feturin a fast Panther Lake processor and integrated stylus. However, the built-in 60 Hz OLED screen is very dark and does not support HDR.

MSI Cubi NUC AI+ 2MG review: Straightforward mini PC for business

The Cubi 2MG prioritizes reliability with generally fewer features than the competition. For almost $900, however, performance-per-dollar isn't one of its strongest qualities.
