Our take on the Micron M550 1TB MLC SATA 6GB/s SED 2.5-Inch Internal Solid State Drive

The Micron M550 is a 2.5-inch SATA III solid state drive built on MLC NAND with a 1TB capacity. It includes self-encrypting drive (SED) support, so data on the drive can be hardware-encrypted when paired with a compatible host. Sequential reads reach roughly 550 MB/s, near the ceiling of the SATA interface. It suits older laptops and desktops, NAS boxes and business machines that need a reliable SATA boot or storage drive with encryption, rather than buyers chasing NVMe speeds. Against current SATA rivals it is a dated MLC design, but MLC endurance is a point in its favor for heavy write workloads.

Best forUpgrading an older laptop or desktop with a 2.5-inch SATA bayBusiness or IT buyers who need hardware encryption (SED)NAS and server use where SATA and endurance matter more than peak speedReplacing a hard drive in a machine without an M.2 slot
Pros
  • MLC NAND gives strong write endurance for a consumer SATA drive
  • Self-encrypting drive support for hardware-based data protection
  • SATA III interface works in almost any laptop, desktop or NAS
  • 1TB capacity holds a large OS, apps and media library
  • Micron is an established NAND manufacturer with its own controllers
Cons
  • SATA speeds top out well below modern NVMe drives
  • MLC-based design is older than current TLC and QLC drives
  • No M.2 form factor, so it won't fit slim modern laptops
  • Encryption only works with a host that supports SED management
  • No bundled cloning software or migration kit

Questions and answers

Is the Micron M550 faster than an NVMe drive?
No. It uses SATA III, which caps around 550 MB/s, while NVMe drives reach several times that. It is a big step up from a hard drive, not from a modern NVMe SSD.
What does SED mean on this drive?
Self-encrypting drive: the hardware can encrypt data on the drive itself. It only works if your system or management software supports SED and you set it up.
Will it fit my laptop?
It fits machines with a 2.5-inch SATA drive bay. Slim laptops that only take M.2 drives have no room for it.
Is MLC NAND better than TLC?
MLC generally lasts longer under heavy writes, which matters for servers and NAS use. For normal desktop use the difference is small.
What comes in the box?
The drive itself. Expect no SATA cable, mounting screws or cloning software, so check what your machine already has.
Can I use it in a NAS?
Yes, SATA 2.5-inch drives work in most NAS units that accept that size, and the endurance suits write-heavy use.
Where is the Micron M550 1TB MLC SATA 6GB/s SED 2.5-Inch Internal Solid State Drive cheapest?
