What the product is

The SanDisk X400 1TB SATA SSD is a 2.5 inch internal drive built with TLC flash for notebooks, ultrabooks and desktops. It delivers sequential reads up to 545 MBps and writes up to 520 MBps with random performance of 95,000 read and 75,000 write IOPS.

What to check before ordering

Confirm the system has a free 2.5 inch drive bay or caddy and a spare SATA III port with a matching data and power cable. The drive is 7.00mm high and 69.85mm wide, so verify the bay accepts that thickness. Operating temperature range is 0°C to 70°C.

How it fits into a build

The drive slots into standard 2.5 inch bays as a drop-in replacement for mechanical hard disks. It uses the SATA interface and requires no additional drivers for TCG OPAL 2.0 encryption support. nCache 2.0 and LDPC error correction help maintain data integrity during heavy workloads.

Questions sur cet article

Does the SanDisk X400 1TB 2.5" SSD come with a mounting bracket or cloning software, or must they be bought separately?

The drive ships as a bare 2.5" 7mm SATA III unit; mounting brackets, SATA cables and cloning software are not included and must be sourced separately.

Should I choose the 1TB 2.5" model or the M.2 2280 version for my laptop upgrade?

Pick the 2.5" 7mm model if your laptop has a standard 2.5" SATA bay; pick the single-sided M.2 2280 model if the slot is M.2 SATA — both deliver 545 MB/s read and 520 MB/s write.

What do the 545 MB/s read and 520 MB/s write figures mean when the drive is installed in a typical SATA III system?

They represent maximum sequential throughput over SATA III; real-world speeds depend on the host controller, file system and workload, while 95,000 read IOPS and 75,000 write IOPS reflect 4KB random performance.
