The Samsung 750 EVO (120GB & 250GB) SSD Review: A Return To Planar NAND
by Billy Tallis on April 22, 2016 8:00 AM ESTATTO
ATTO's Disk Benchmark is a quick and easy freeware tool to measure drive performance across various transfer sizes.
The ATTO benchmark shows the 750 EVO has good performance on small transfers and a maximum write speed that is very close to the read speed. The 120GB 750 EVO even provides better write speeds than the 850 Pro 128GB thanks to the former's SLC write caching.
AS-SSD
AS-SSD is another quick and free benchmark tool. It uses incompressible data for all of its tests, making it an easy way to keep an eye on which drives are relying on transparent data compression. The short duration of the test makes it a decent indicator of peak drive performance.
The 750 EVO provides top-notch burst speeds for reads and writes. The write speeds in particular distinguish the 750 EVO from most other TLC drives and low-end MLC drives that suffer from a lack of parallelism at small capacities.
Idle Power Consumption
Since the ATSB tests based on real-world usage cut idle times short to 25ms, their power consumption scores paint an inaccurate picture of the relative suitability of drives for mobile use. During real-world client use, a solid state drive will spend far more time idle than actively processing commands. Our testbed doesn't support the deepest DevSlp power saving mode that SATA drives can implement, but we can measure the power usage in the intermediate slumber state where both the host and device ends of the SATA link enter a low-power state and the drive is free to engage its internal power savings measures.
We also report the drive's idle power consumption while the SATA link is active and not in any power saving state. Drives are required to be able to wake from the slumber state in under 10 milliseconds, but that still leaves plenty of room for them to add latency to a burst of I/O. Because of this, many desktops default to either not using SATA Aggressive Link Power Management (ALPM) at all or to only enable it partially without making use of the device-initiated power management (DIPM) capability. Additionally, SATA Hot-Swap is incompatible with the use of DIPM, so our SSD testbed usually has DIPM turned off during performance testing.
Idle power consumption of the 750 EVO is comparable to other Samsung drives: great when ALPM is enabled, and average when it is disabled.

System builders will likely go even cheaper there are a lot of 240GB drives around $60. Nearly a $20 difference.Murloc - Saturday, April 23, 2016 - link
They're going to put it into computers and write "Samsung SSD inside" and it will be cheaper for the system builders, but the average customer will not be able to tell the difference.So yes, it's a winner.

You think $10 is worth the downgrade? Bruh...5th element - Friday, April 22, 2016 - link
To the 3rd party selling complete machines to the everyday masses yeah. Like haukionkannel said above. Most people out there aren't tech heads and the lower £££ matters.lilmoe - Saturday, April 23, 2016 - link
Sure, but the price difference is even lower with higher volume...nathanddrews - Friday, April 22, 2016 - link
Meh.Thanks for the great review - as always. The "meh" is just for the drive itself.

The problem I have with SSDs right now is that they're so boring to me. What I need in my life are consumer grade NVMe 2TB+ SSDs. I'm sick and tired of buying multiple SSDs or splitting my application and data across SSDs and HDDs. One drive to rule them all, please.TheinsanegamerN - Friday, April 22, 2016 - link
We should probably work on getting 1TB drives out and purchasable before worrying about 2TB models.vanilla_gorilla - Friday, April 22, 2016 - link
Samsung 850 EVO 1TB SSD are $291 on Amazon (Prime) right now. And the Samsung 850 EVO 2TB is the same price per gigabyte ($600 for 2TB).Meteor2 - Friday, April 22, 2016 - link
I don't know about 2+ TB but definitely more 1 TB NVMe drives. SATA is yesterday's tech.
