Frequently asked questions

What are the sequential read and write speeds of the Samsung 840 PRO 128GB?

The 128GB model delivers maximum sequential read speeds of 530MB/s and sequential write speeds of 390MB/s. These speeds are achieved through Samsung's proprietary Toggle DDR 2.0 NAND flash and 256MB LPDDR2 DRAM cache, enabling fast file transfers and application loading in client computing environments.

What random I/O performance can I expect from this SSD?

At queue depth 32 (QD32), the 840 PRO 128GB achieves 97,000 IOPS for random reads and 90,000 IOPS for random writes. At QD1, performance is 9,800 IOPS read and 31,000 IOPS write. This makes it suitable for multitasking workloads and enterprise applications requiring responsive system behavior.

Does the Samsung 840 PRO support encryption?

Yes, the drive includes AES-256 full-disk encryption (FDE) for protecting sensitive data. It also supports TRIM and garbage collection to maintain performance over time, plus S.M.A.R.T. monitoring for drive health tracking and predictive failure detection.

What is the power consumption profile of the 840 PRO?

Average operating power is 0.069W typical. Idle power consumption is 0.054W with DIPM (Device-Initiated Power Management) enabled or 0.349W with DIPM disabled. This low power profile makes it ideal for laptops and battery-powered systems requiring extended runtime.

What warranty and reliability metrics does Samsung provide?

The 840 PRO includes a 5-year limited warranty for client PC use. The drive has a mean time between failures (MTBF) of 1.5 million hours, indicating excellent long-term reliability. Operating temperature range is 0–70°C with non-operating range of -55–95°C.

Is the 840 PRO compatible with older SATA systems?

Yes, the drive uses SATA 6Gb/s interface but is backward compatible with SATA 3Gb/s and SATA 1.5Gb/s systems. However, performance will be limited by the slower interface speed. For optimal 530MB/s read performance, a SATA 6Gb/s controller is required.

What is the physical form factor and weight?

The 840 PRO is a standard 2.5-inch form factor with dimensions of 100 x 69.85 x 6.8mm and weighs a maximum of 54 grams. This compact size fits standard 2.5-inch drive bays in laptops, desktops, and external enclosures.
