Seagate BarraCuda 120 SSD Spec and Price in the United States

Name: Seagate BarraCuda 120 SSD
Brand: Seagate

SATA2TB2.5-inch560 MB/s read

Anyone replacing a mechanical hard drive without moving to NVMe is the target for the BarraCuda 120: a 2.5-inch SATA drive with TLC NAND rated for 560/540 MB/s and 90,000 IOPS in both directions, essentially topping out what the SATA interface allows. Its 1170TB TBW rating sits well above the Q5's 531TB and just below the FireCuda 530's 2550TB, with a 5-year warranty matching the FireCuda 530 despite the far lower throughput a SATA connection allows. It's built for everyday desktop and laptop upgrades rather than write-intensive workloads.

Tied 87th of 106 models in the SSD catalog on Sequential read — 8 models share this figure.

How to choose an SSDFour questions decide almost every SSD purchase — what fits, how big, how fast, and how much it should cost.NVMe or SATAWhich interface your machine takes, how to tell without opening it, and what the speed difference actually buys you.How much SSD capacity you actually needHow to size a drive from what you already use, why leaving headroom matters, and when one bigger drive beats two small ones.M.2 sizes and SSD form factorsWhat 2280, 2242, and 2.5-inch mean, which one your machine takes, and how to check the keying before you buy.What SSD speed numbers actually tell youSequential versus random performance, why the number on the box describes the rarer case, and how to read it without being misled.PCIe generations for SSDsWhat Gen 3, Gen 4, and Gen 5 change, why a newer drive always works in an older slot, and when the extra speed is worth paying for.TLC, QLC, and DRAM-less SSDsWhat the NAND type and the controller's cache change about how a drive behaves, and when either is worth caring about.SSD endurance and warrantiesWhat TBW and DWPD actually promise, how much a normal machine writes, and when endurance is worth paying extra for.How to install an SSDFitting an M.2 or 2.5-inch drive, choosing between cloning and a clean install, and what to check on the first boot.When an SSD price is actually goodWhy price per terabyte beats any discount percentage, and why a good price on one capacity says nothing about the others.
