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.

Meh. I'll wait until it's half price.haukionkannel - Friday, April 22, 2016 - link
Well, this is 10$ cheaper that 850evo, so this will be very popular among system builders and other with tight budget. Normal upgrade user will definitely go for 850. But this is good enought to most customers.Space Jam - Friday, April 22, 2016 - link
$10 for considerably worse performance does not a winner make.I have a hard time swallowing the cheapo, terrible performance $60 TLC drives. If Sammy thinks anything more than $65 is a good price they have another thing coming.
$60 for a budget 120GB SSD is some audacity.
I and most others will stick to BX100s @ $70 and 850 EVOs @ $75 during the (frequent) sales.

And if it's upgrading a lot of the older machines desktops and laptops that still only run on SATA II...it doesn't matter. As long as it pushes 285MBps (ish) all day that's all it needs. A lot of kit out there is still SATA II.Alexvrb - Friday, April 22, 2016 - link
Yeah it's got a sequential speed cap. Not all tasks are about peak speeds. I'm pretty sure in terms of IOPS a decent SSD will still beat the snot out of an OEM-grade penny-pinching budget model, even on old SATA 2. Which brings us back to the idea that this is for OEMs and builders - truly this is a "builder-grade" component. If you're upgrading or building for yourself, you'll likely pay a few extra bucks for an 850 Evo or similar unit.With that being said, any of the modern SSDs are better than a mechanical drive. Blech.

this drive will likely be perfect for the older apple laptops that have that dodgy cable that does not support SATA 3 but the controller does (the cable fails if a high speed cable is used) i had to use a DVD HDD caddy on number of apple laptops due to that issue where it will not detect the SSD or HDDleexgx - Wednesday, April 27, 2016 - link
high speed drive is used (not cable is used) edit be nice on here but that's unlikelyDeath666Angel - Friday, April 22, 2016 - link
I'm guessing the marketing value for "Performance Samsung SSD inside" is considerably higher than comparable Sandisk or Crucial SSDs. And the 10 bucks off compared to the 850 means the margins remain. And if current 1TB laptop drives get replaced by these 250GB 750s, I think everyone is a winner. :DSamus - Monday, April 25, 2016 - link
It's funny you mention that because I would prefer a Sandisk or Crucial/Micron drive over a Samsung anyday.Have you ever tried warranting a Samsung drive? They are hell to deal with. And yes, I still have a sour metallic taste after the 840 Evo debacle that essentially was never fixed.
I also think Crucial/Sandisks Marvell drives, albeit slower, are more consistent, stable and deal with power loss substantially better than the MGX. The fact Samsung is making an SSD with 35TBW endurance in 2016 is pretty damning. I've seen 20GB racked up on old Intel X25-M's in a matter of years so 35GB in a 5 year period isn't out of the question. Just about any other SSD or hard disk for that matter will handle double that no problem at the rated capacity.

" after the 840 Evo debacle that essentially was never fixed."Don't know what you mean, I also have a 840 EVO and can confirm the performances issues are gone after the 2nd fix.
