High-Capacity SATA SSD for Consumer Storage
The Samsung 870 QVO Series MZ-77Q4T0BW is a 2.5 inch internal solid-state drive with a 4TB capacity. It connects via a SATA III interface and uses Samsung V-NAND 4bit MLC memory managed by a Samsung MKX controller. A 4 GB Low Power DDR4 SDRAM cache supports burst performance. The drive is built for consumer workloads and offers sequential reads up to 560 MBps and writes up to 530 MBps.
Suitable for Bulk Data.
This drive suits users who need affordable, high-capacity storage for media libraries, backups and general file archives on systems with 2.5 inch SATA bays. Random read performance reaches 98,000 IOPS and random write reaches 88,000 IOPS for everyday responsiveness. It is less appropriate for workloads that demand sustained high write throughput or the lower latency of a PCIe interface. The 1,500,000 hour MTBF and 1500G shock resistance support reliable operation in laptops or desktops.
4TB Capacity Decides Fit
The single specification that determines whether this is the right part is the 4TB capacity. Buyers must confirm their system accepts a 2.5 inch SATA drive of this physical size and that the storage volume meets their needs. Power draw is 35 mW idle and 3.2 W active, with an operating range of 0°C to 70°C. The drive measures 6.80 mm high, 100.00 mm wide and 69.85 mm deep, weighing 54.00 g.

أسئلة حول هذا المنتج
What SATA port does my motherboard need for the 870 QVO MZ-77Q4T0BW to work?
The drive uses a SATA III interface, so a motherboard with a SATA 6 Gb/s port will let it reach the rated 560 MBps read and 530 MBps write speeds.
Can I keep my older SATA II drive and run it alongside this 4 TB SSD?
Yes, both drives connect to separate SATA ports; the 870 QVO will operate at SATA III speeds while the older drive remains limited to its own SATA II throughput.
How do I confirm the 870 QVO is delivering its rated 98,000 IOPS random read performance after installation?
Run a 4 KB random-read benchmark such as CrystalDiskMark or AS SSD and verify the result approaches 98,000 IOPS on a SATA III port with AHCI enabled.
