Samsung 840 EVO SSD: Tested At 120, 250, 500, And 1000 GB

Test Setup And Benchmarks

Our consumer storage test bench is based on Intel's Z77 Platform Controller Hub paired with an Intel Core i5-2400 CPU. Intel's 6- and 7-series chipsets are virtually identical from a storage perspective. We're standardizing on older RST 10.6.1002 drivers for the foreseeable future.

Changes in RST's driver packages occasionally result in subtle performance changes. They can also lead to some truly profound variance in scores and results as well, depending on the driver revision. Some versions flush writes more or less frequently. Others work better in RAID environments. In fact, builds 11.2 and newer even support the TRIM command in RAID. Regardless, results obtained with one revision may or may not be comparable to results obtained with another, so sticking with one build across all tests is mandatory.

    Surely it would make sense to compare it to the vanilla SSD840. Also, there's no 840 Pro in the power charts.

    While the 1TB drive coming down to ~65c/GB is nice, seeing the 120 GB drives get near there would be nice. Especially since this is meant to be the value king.

    I have 2 840 pro 512 GB SSD's (1 on my notebook 1 on my PC)

    I got them on a sale on Newegg for around $500 for both of them. :)

    A 1TB would be cool if I find it on sale....
    or maybe I should try out writing a letter to someone fat in some weird red costume...

    The performance gap between the 840 Evo and 840 Pro is discouraging for the lower capacity models. I understand that the Pro is the flagship product but I was expecting less of a gap in in the 120GB models since this is a newer generation product and the 840 Pro is still based on the 21nm MLC NAND. However, the 1TB model is is a great choice for mass SSD storage. Lets hope the prices drop below $0.50 per GB soon.

    MLC is faster than TLC, and bigger node NAND is usually faster. Only reason to go smaller is price and power.

    I wonder if samsung plans on releasing a pro evo series since the regular series evo is to replace the older non pro versions.

    ripoff, high prices for triple level flash especially at 19mm, the lifespan will likely suck and their shortened warranty represents that.

    Cost for performance = Very High . ofcourse its not going to perform like a Pro but for the cost im amazed its that much better than the Regular 840.

    Samsung makes some good looking drives. I'm loving the matte grey.

    Glad this review also refutes the perception of low TLC write endurance in normal desktop workloads. Been using a 128GB 840 in a daily-use desktop for eight months now and the endurance counter hasn't decremented at all. I'll have replaced the entire rig long before it wears out.

    Interesting review. I think the point to remember is that the 840 EVO is not a high end enthusiast ssd like the 840 Pro. Instead, consider the 840 EVO as a mainstream ssd suitable for most consumer and home office scenarios.
