Capacity and fit
This Samsung M6 Series HM320JI is a 320GB 2.5-inch internal hard drive built for laptops that accept a 9.5mm drive height. It suits users replacing an older mechanical drive or adding storage to a compatible notebook bay. The bare-drive packaging means no brackets or cables are included. Buyers who need more capacity or a thinner 7mm profile should look elsewhere.
SATA 1.5Gb/s interface
The drive connects through a SATA 1.5Gb/s interface, which limits maximum transfer rates to 150MB/s. Average seek time is 12ms and average latency is 5.6ms at 5400 RPM. Systems with only SATA 3Gb/s or 6Gb/s ports will still work but the drive will not run faster than its native link speed. Builders who require the higher throughput of later SATA revisions will not get it here.
Straightforward installation
Installation follows the standard 2.5-inch SATA mounting pattern used in most notebooks. The 9.5mm height fits the majority of drive caddies, though some ultra-thin chassis only accept 7mm drives. The bare drive has no pre-installed operating system, so a fresh OS install or disk clone is required after fitting. Users without a SATA data cable or mounting screws must source them separately.

Questions about this item
Is the 320GB capacity the only option in this M6 series?
The M6 series HM320JI model is supplied as a 320GB drive; other capacities in the same series are separate part numbers.
What does the 5400 RPM rating mean for everyday laptop use?
5400 RPM with 12ms average seek and 5.6ms latency gives typical notebook throughput for office tasks and media storage.
The drive lists SATA 1.5Gb/s — will it run slower on a SATA 3Gb/s or 6Gb/s port?
SATA 1.5Gb/s (150 MB/s) is the drive's native link speed; it will operate at that rate even when connected to faster SATA ports.
