MediaRange MR1003 480GB 2.5-inch SATA III Internal SSD, 7 mm, up to 550 MB/s Read, TLC NAND, Black

MediaRange MR1003 480GB is a 2.5-inch 7 mm SATA internal SSD on SATA III 6Gb/s (Rev. 3.0), rated up to 550 MB/s read and 490 MB/s write, built for desktop and laptop upgrades where a silent, shock-resistant drive replaces an old hard disk.

A 2.5-inch SATA SSD is the simplest upgrade there is for an older laptop or desktop that still boots from a hard drive: it uses the same SATA data and power connectors, so there is no new slot, no BIOS setting and no adapter card to worry about. What you get is a system that starts, opens programs and searches files in seconds instead of minutes, runs silently and survives the knocks that kill spinning disks.

Installation takes a few minutes: power down, unplug, remove the old drive or fit this one in a free bay, connect SATA data and power, and either clone your old system or install Windows fresh. After that there is nothing to maintain — Windows detects the SSD and turns off defragmentation automatically, and TRIM keeps write performance steady over the years. Keep at least 10–15% of the drive free; every SSD slows down and wears faster when it is run completely full.

• MediaRange MR1003 SSD 480GB in a blister pack — no mounting bracket, screws or cables included

• Plugs into any standard SATA data + power connector — the same cables your current 2.5" or 3.5" hard drive uses.
• Speed is capped by the SATA 6Gb/s interface (about 550 MB/s in practice); the big change compared with a hard drive is access time, not just MB/s.
• On a SATA II (3Gb/s) port it still works, but sequential speed drops to roughly half.
• 480GB formatted shows slightly less in Windows (decimal vs binary units) — this is normal for every drive.
• 480GB is a comfortable single-drive size for a work laptop: system, applications and several years of documents.

• M.2-only laptops and mini PCs without a 2.5-inch drive bay — this drive needs a SATA bay and connector.
• External use on its own: to plug it in by USB you need a separate 2.5" USB enclosure or adapter.
• NVMe speeds: no SATA drive goes beyond the ~550 MB/s limit of the SATA interface.
• Servers, NAS or 24/7 recording: MediaRange specifies this drive for desktop and laptop use, not continuous server or data-centre operation.
