AnandTech Storage Bench - Heavy

Our Heavy storage benchmark is proportionally more write-heavy than The Destroyer, but much shorter overall. The total writes in the Heavy test aren't enough to fill the drive, so performance never drops down to steady state. This test is far more representative of a power user's day to day usage, and is heavily influenced by the drive's peak performance. The Heavy workload test details can be found here.

AnandTech Storage Bench - Heavy (Data Rate)

The Samsung 950 Pro was still unmatched in average data rate, even against higher capacity competition. The 2TB 960 Pro pushes the limits a little further.

AnandTech Storage Bench - Heavy (Latency)

The 2TB 960 Pro delivers a slightly lower average service time than the 512GB 950 Pro, and the other PCIe SSDs are well behind.

AnandTech Storage Bench - Heavy (Latency)

Samsung's PCIe SSDs and the Intel 750 are all very close in terms of the number of high-latency outliers they experience, while the other PCIe SSDs and the best SATA SSDs are 2-4x worse.

AnandTech Storage Bench - Heavy (Power)

The 960 Pro's power consumption is almost identical to the 950 Pro. Samsung's PCIe SSDs have a clear lead over other PCIe SSDs but are not as efficient as the SATA drives.

    the problem with windows 10 when using as a benchmark system is you got to make sure automatic maintenance is disabled and windows update is disabled or it mess the results up (i have 2 laptops and both of them go nuts when screen turns off on win10{fan revved up and lots of SSD activity)

    i would personally stick with windows 7 or 8 as they are more predictable

    if using windows 8 and 10 you need to disable the idle maintenance auto task (set windows update to never check) and windows 10 you have to disable the windows update service as it can mess up benchmark results (or if using windows 10 pro use GPedit to set windows update to ask before downloading, note pressing check or download actually means download and install on windows 10 pro)

    If I replace my Vertex 3 120Gb Sata3 SSD with this one and use my PC for normal tasks like web browsing and gaming, will I notice any difference? Thats the real question to me.

    Cheers

    The biggest one will be being able to have all yours games on SSD instead of just 1 or 2. Even a cheap SSD is fast enough that IO rarely is a major bottleneck in day to day consumer use. Reply

    For the money you will spend, you will not notice a significant difference. If the rest of your system is of the same vintage as the SSD you're replacing, that will be even more true. Reply

    And here's the evidence.

    There's a typo in the form factor for 960 drives, "Sngle-sided". Also, if the form factor is the same for both drives shouldn't the cell be merged?

    Does this make the 950 Pro obsolete at this point too? At least for the 512GB version.

    Thanks. I fixed the typo, but left the two cells separate and split the PCIe interface so that there's an uninterrupted vertical line separating the old drives from the new.

    Once the 512GB 960 Pro is widely available and once Samsung delivers the drivers for it, there should be no reason to get the 512GB 950 Pro. I do hope to confirm that directly by testing a 512GB 960 Pro against the 950 Pro, but sample supplies have been pretty limited for this launch. The 256GB 950 Pro won't have a direct successor, but if the 960 EVO does what it's supposed to it should offer better real-world performance at a much lower price.

    I'd say price would be a big one. If you can get the 950 pro for $100 less then the 960 pro of the same size, unless you need all that speed the 950 pro would be a better deal. Reply

    How was the 960 Pro connected during the test?
    On the Asus Z97 mobos M.2 connector that shares bandwidth Sata Express #1?

    If so, is it recommended to unplug any other Sata drive from this Sata port #1 and use a separate Sata port for that device (for not loosing performance under heavy workload where multiple SSD-drives are in use?

    Or was the 960 Pro connected to a PCIE 3.0 via adapter?
    Please explain this and the possible benefits for one or the other, consider a hefty game GPU connected to PCIE 3.0 x16 slot on a similar mobo (Asus Z97 Deluxe).

    The SSD testbed doesn't have a discrete GPU, so all PCIe SSDs are tested in the PCIe 3.0 x16 slot. There's a riser card with the power measurement circuitry between the SSD and the motherboard. M.2 PCIe SSDs are tested in a simple passive PCIe x4 to M.2 adapter card which is plugged in to the power measurement riser card. I'll also be testing the 960 Pro with the Angelbird Wings PX1 adapter and heatsink as I dig deeper into its thermal performance. Reply
