Frequently Asked Questions
What is a U.2 SSD?
A U.2 SSD (sometimes written U2) is a front-serviceable enterprise drive in a 2.5-inch enclosure that connects over PCIe and uses the NVMe protocol. It fits compatible servers, storage systems, workstations and embedded platforms.
U.2 vs U.3: what is the difference?
Both use a serviceable 2.5-inch enclosure. U.3 is built around the SFF-TA-1001 specification and can run in a tri-mode backplane that also accepts SAS and SATA drives. U.2 and U.3 are not interchangeable on physical size alone, so confirm the connector, backplane and host support.
Do you offer enterprise U.2 and U.3 SSDs?
Yes. Enterprise U.2 and U.3 drives are available in PCIe Gen4 and Gen5 from 1.6TB to 30.72TB, with enterprise TLC NAND and a DRAM cache. Selected drives add hardware power-loss protection, dual-port operation, SR-IOV on Gen5 and T10 Protection Information. Enterprise drives are rated for commercial temperature (0°C to 70°C) and built for 24/7 server and storage workloads. with your capacity, interface and endurance needs.
Which PCIe generations are available?
U.2 drives are available in PCIe Gen5, Gen4, Gen3 and Gen2, and U.3 drives in PCIe Gen4 x4 with NVMe 1.4. Gen5 U.2 drives are commercial grade, from 7.68TB to 30.72TB in a 15mm enclosure: .
What capacities and NAND types are available?
U.2 drives range from 128GB to 30.72TB with 3D TLC and pSLC. For MLC, contact us to verify availability. U.3 drives range from 1.6TB to 30.72TB with 3D TLC, including dual-port models.
What endurance do U.2 SSDs offer?
3D TLC drives are rated from 0.6 drive writes per day (DWPD) for read-intensive workloads to 1 DWPD for mixed use, and pSLC drives from 25 to 40 DWPD for write-heavy workloads. Selected drives are rated for 2 million hours MTBF. Endurance depends on capacity, NAND and grade: for the rating of a specific part.
Are industrial-temperature U.2 SSDs available?
Yes. Industrial U.2 drives are rated from −40°C to 85°C and commercial drives from 0°C to 70°C, and automotive-grade Gen4 U.2 drives are also available. U.3 drives are commercial grade.
Are security and radiation-hardened options available?
Yes. AMP U.2 NVMe drives from 1TB to 8TB are NIAP Common Criteria certified and on the NSA CSfC Components List for hardware full drive encryption. See Common Criteria & CSfC drives for the certified models. Radiation-hardened drives are available in U.2. with your requirements and AMP will confirm the exact part, firmware and certification status.
Do all U.2 and U.3 SSDs include power-loss protection and encryption?
No. Every drive has a DRAM cache, but power-loss protection, self-encryption, TCG Opal, T10 Protection Information, hot plug, Sanitize, Telemetry, SR-IOV and dual port vary by product family and part number. Each product page lists what that drive supports.
Can AMP support custom endurance or firmware requirements?
Yes, on selected U.2 configurations. Options include performance-tuned firmware, over-provisioning, endurance options and thermal or mechanical enhancements, depending on capacity and project requirements.
Can AMP help replace an end-of-life U.2 or U.3 drive?
Yes. Send the existing part number, host or backplane, interface generation, capacity, temperature range and annual quantity, and AMP will recommend compatible options to qualify.
