Will this fit my ThinkPad?

It fits machines with a 2.5-inch SATA drive bay. Many slim ThinkPads use M.2 or mSATA instead, so check your model's drive type before buying.

Is it faster than the hard drive it replaces?

Yes. Any SATA SSD cuts boot and load times sharply compared with a spinning drive. It will not match an NVMe drive, but older SATA-only machines cannot use one anyway.

What is MLC NAND and does it matter?

MLC stores two bits per cell and generally endures more write cycles than TLC. For everyday use the difference is small, but it suits heavy-write roles like a small server or workstation.

Does it come with cloning software or a cable?

The drive is listed on its own. Plan on a clean OS install or supply your own cloning tool and SATA cable.

It is fine for an OS and core applications. Games, video and large photo libraries will fill it quickly, so pair it with a second drive if you store media.
