NVMe SSDs

NVMe SSDs connect over PCIe instead of SATA, which removes the SATA ceiling and cuts latency. That suits databases, virtual machine hosts, ZFS pools and scratch space. They come in three shapes. U.2 drives are 2.5 inch datacenter SSDs that plug into NVMe backplanes or connect through a cable or PCIe adapter. M.2 drives are small boards for motherboard slots and adapter cards. Add-in cards sit directly in a PCIe slot. Before you order, check that your host has the right connector and enough PCIe lanes, and that the slot can boot from NVMe if you need it to. For used drives, the SMART percentage used value shows how much of the rated endurance is gone; we list the health figure and power-on hours we read from each drive. Every used SSD passes a SMART health check and an extended self-test before it ships.

NVMe SSDs: common questions

Can I use a U.2 drive without a U.2 backplane?+

Yes. A PCIe to U.2 adapter card, or an M.2 to U.2 cable adapter, lets a U.2 drive run in a normal PCIe slot. U.2 drives can run warm, so give them airflow.

What is the difference between U.2 and M.2?+

Both are NVMe over PCIe. U.2 is a 2.5 inch hot-swap form factor with room for more flash and power loss protection; M.2 is a small board that mounts on a motherboard or adapter. Pick the one your host supports.

How do I check wear on a used NVMe SSD?+

Read the SMART log with smartctl or nvme-cli and look at Percentage Used. Zero means unused; 100 means the rated endurance has been reached, although many drives keep working past it.

What warranty comes with these drives?+

Used drives carry a 90-day warranty, and certified tiers carry up to 2 years; the exact term is on each listing. New sealed drives keep the manufacturer warranty. Every order also has 30-day returns.
