Silicon Power UD70 PCIe 3.0 NVMe SSD review - Specifications & Features

Features

UF70 PCIe Solid State Drive adopts PCIe Gen3x4 high-speed interface and compatible M.2 2280 specification. The maximum read/write speed can reach 3000 MB/z, and the random read/write capacity of 4K IOPS ~600K can greatly increase the efficiency of data processing. A large capacity of up to 8TB is released for professional users, which can meet the needs of creators and gamers who need large amounts of storage space for their material. And the built-in smart algorithm management mechanism can ensure operation efficiency, speed and data storage stability. The SSD is available in 500GB, 1TB and 2TBcapacities. Conveniently slotting directly into a motherboard thanks to its M.2 2280 industry-standard NVMe form-factor, the SSD boasts wide-ranging compatibility and high-bandwidth performance, while its high-density 3D QLC NAND memory ensures better value than the previous generation TLC NAND, able to store more data in the same amount of physical space.

With endurance up to 520 TB Written and a five-year warranty for guaranteed peace of mind, the UD70 offers proper M.2 performance and massive capacities available to more PC builds than ever before.

• PCIe Gen 3x4 interface with read speeds up to 3,400MB/s and write speeds up to 3,000MB/s
• NVMe 1.3 support allows for higher performance, lower latency, and lower power consumption
• Equipped with 3D QLC NAND storage technology for larger capacity and higher performance on a small form factor
• Available in 3 storage capacity options: 500GB, 1TB, and 2TB
• Supports SLC Caching and DRAM Cache Buffer to improve sequential read/write and random read/write performance
• Dual self-cooling system via active state power management (ASPM) and autonomous power state transition (APST)
• Built-in thermal throttling effectively monitors and regulates the temperature to keep it in the normal range for greater system reliability and data integrity
• Engineered with low density parity check (LDPC) coding to ensure accuracy of data transmission and reliability of data access
• Built-in E2E data protection for enhanced data transfer integrity
• Adopts AES 256-bit encryption to ensure data security
• Small form factor M.2 2280 (80mm) allows for easy installation in laptops, small form factor PC systems, and some ultrabooks

Phison 5012-E12 controller

The NAND ICs are driven by a Phison 5012-E12 controller. The PS5012-E12 makes use of the NVMe revision 1.3 protocol and as you have been able to notice from the SSD specifications, this controller is advertised at a very fast ~3000 MB/s (depending on volume size) across four PCIe lanes for read and write operations respectively, over an x4 PCIe Gen 3 lane connection that is. The controller can address 8 channels. It is also ready for QLC and the 96-layer NAND. The controller will offer support for up to 8 TB storage as well as offering support for external Thunderbolt 3 SSDs. The PS5012-E12 is available in three versions: the 'normal' PS5012-E12 for high-end SSDs, the PS5012-E12C for mid-range devices and the PS5012-E12DC for the business market. 

As you can understand, it is ready for SLC/MLC/TLC and QLC and 96-layer NAND. The controller supports for up-to 8 TB storage as well as offering support for external Thunderbolt 3 SSDs.
