The Samsung 750 EVO (120GB & 250GB) SSD Review: A Return To Planar NAND
by Billy Tallis on April 22, 2016 8:00 AM ESTSequential Read Performance
The sequential read test requests 128kB blocks and tests queue depths ranging from 1 to 32. The queue depth is doubled every three minutes, for a total test duration of 18 minutes. The test spans the entire drive, and the drive is filled before the test begins. The primary score we report is an average of performances at queue depths 1, 2 and 4, as client usage typically consists mostly of low queue depth operations.
The 250GB 750 EVO comes in right behind the 850 EVO and Pro for sequential read speed, and the 120GB 750 EVO surprises by coming in fourth, significantly ahead of both the 120GB 850 EVO and 128GB 850 Pro.
Power consumption for the 750 EVO is a little high but nothing concerning. Only a few MLC drives distinguish themselves with particularly high efficiency during sequential reads.

The high performance score of the 750 EVOs is due primarily to their unusually good QD1 speeds, which are quite close to the limit reached at higher queue depths.
Sequential Write Performance
The sequential write test writes 128kB blocks and tests queue depths ranging from 1 to 32. The queue depth is doubled every three minutes, for a total test duration of 18 minutes. The test spans the entire drive, and the drive is filled before the test begins. The primary score we report is an average of performances at queue depths 1, 2 and 4, as client usage typically consists mostly of low queue depth operations.
Sequential write speeds of the 750 EVO are significantly lower than the 850 EVO and not competitive with MLC drives, but are in the lead among planar TLC drives.
Power consumption for the 750 EVO is significantly higher than the 850 EVO, but it is still more efficient than the planar TLC competitors.

Most drives show no scaling with queue depth in this test, and the 750 EVO follows suit.

The cheap SSD will still blow the spinning rust in the other crappy TN 720p laptop out of the water.jabber - Friday, April 22, 2016 - link
Yeah amazing how limited people's imaginations are when it comes to hardware and other peoples usage needs. Unless it's pushing 2GBps it's junk. Tedious people. If every laptop in the world with a cheap 5400rpm HDD in it swapped to one of these 'bottom of the barrel' Samsung SSDs, it would be a revelation. Make my job of support a lot easier and faster.Movieman420 - Friday, April 22, 2016 - link
Keep in mind, launch prices are always a bit high. Sammy could sell em for less at retail...but they're really not after retail with the 750...they wanna move em in bulk minus retail packaging costs. As far as performace, they're just right...for the intended market. As a budget OEM part, the vast majority of end users (80% maybe?) will fall in Anands light bench metric where this drive makes a pretty good showing. Any better would risk cannibalizing EVO sales. Overall, this product and placement was well thought out by Samsung...as usual....and from a performance standpoint a lil over-provisioning goes a long way. I'm assuming it's not compatible with magician's RAPID mode...unless say your a huge oem customer who'd pay a tad extra and make it a performance offering in more expensive lappys with enuff ram.

What we need to know is final street price, not launch price.Because as it stand i have Zero reason to buy them. It needs at least a 50% price cost.versesuvius - Saturday, April 23, 2016 - link
As long as Samsung is clearing unused chips from its stock, it could just offer these drives for $25 each to make a gesture of good will towards its existing customers and make some new ones too.The_Assimilator - Saturday, April 23, 2016 - link
Good to see you're "revieiwng" this drive. Could you maybe consider reviewing a spellchecker and/or editor in future?zodiacfml - Saturday, April 23, 2016 - link
Cheapest option but purchased separately, $10 difference is not worth it.The perrformance of the 850 is useful for most people savvy enough to replace drtives.

$10 may be a big BOM savings for large system builders but it's pocket change for consumers looking to upgrade from a hard drive. This drive probably isn't aimed at you :)I wouldn't trade $10 for half the write longevity and potentially other issues from using planar TLC. The 850 Evo is still the king and the Sandisk Ultra II is also a good deal when it goes on sale.

How is the Corsair LE compared to 850 EVO, 750 EVO? In terms of reliability?odedia - Sunday, April 24, 2016 - link
According to Amazon.com, this drive is currently more expensive then the 250gb 850 Evo. Makes zero sense to buy this today. maybe in a year it will be priced accordingly.
