8TB SATA III QLC drive

The Samsung 870 QVO MZ-77Q8T0B/AM is an internal solid state drive with an 8TB capacity and a 2.5 inch form factor. It uses Samsung 4-bit QLC V-NAND and a MKX controller on a SATA III interface. The drive targets desktop PC and laptop users who need large storage volumes for consumer workloads.

Upgrade from hard drives or smaller SSDs

Replacing a mechanical hard drive with this SSD removes moving parts and raises sequential speeds to 560 MBps read and 530 MBps write. The jump is worth it when a system supports the standard 2.5 inch SATA form factor and the user wants up to 2880 TBW of endurance with AES 256-bit encryption.

Sustained workload behaviour

Under continuous use the drive draws 2.2W on average and 4W at maximum while operating between 0°C and 70°C. Random performance reaches 98,000 IOPS read and 88,000 IOPS write at QD32, supported by a refined ECC algorithm. MTBF is rated at 1,500,000 hours for long-term reliability.

Questions about this item

Will the 7 mm height 2.5 inch form factor fit my laptop drive bay?

The drive measures 7 mm tall, 70 mm wide and 100 mm deep, matching the standard 2.5 inch SATA enclosure used in most laptops and desktops.

Do I need a SATA data cable and a SATA power connector to install the MZ-77Q8T0B/AM?

Yes, connect a SATA data cable to the motherboard and a SATA power lead from the PSU; the step often missed is securing the drive with screws so the connectors stay seated.

How many terabytes can be written before the 8 TB QLC V-NAND reaches its endurance rating?

The drive is rated for 2880 TBW, after which the memory cells may no longer reliably retain data.
