The Samsung 750 EVO (120GB & 250GB) SSD Review: A Return To Planar NAND
by Billy Tallis on April 22, 2016 8:00 AM ESTAnandTech Storage Bench - Light
Our Light storage test has relatively more sequential accesses and lower queue depths than The Destroyer or the Heavy test, and it's by far the shortest test overall. It's based largely on applications that aren't highly dependent on storage performance, so this is a test more of application launch times and file load times. This test can be seen as the sum of all the little delays in daily usage, but with the idle times trimmed to 25ms it takes less than half an hour to run. Details of the Light test can be found here.
The average data rate scores of the 750 EVOs allow it to blend in to the crowd as a solid performer and the fastest planar TLC drive on the Light test.
The average service time of the 750 EVO again places it as one of the fastest planar TLC drives and a reasonable performer compared to the SATA market overall. The 120GB 750 EVO is also relatively close to the 250GB version, while other 120GB models are considerably slower than their larger counterparts.
The number of latency outliers experienced by the 750 EVO in the Light test is normal for TLC drives but considerably higher than most MLC drives.
Power usage over the course of the Light test separates the drives pretty cleanly into different categories. The 750 EVO clearly requires more power than the 850 EVO, and all the other TLC drives require more power than the 750 EVO. The MLC drives all require less energy than all the TLC drives, except that the 850 Pro sacrifices efficiency to deliver its high performance.

The prices aren't competitive. The Ultra II in particular tends to go on sale rather often for around $50.Shadow7037932 - Friday, April 22, 2016 - link
Also, if it's anything like the price drop we saw with the 850 EVOs, this could drop down to ~$50 or so in a few months I think.barleyguy - Friday, April 22, 2016 - link
This drive hasn't been out long enough to know what price it will go on sale for. So I consider any comments on pricing pretty irrelevant.Outside of that, there are only 3 brands of SSD I trust my data to, which is Intel, Crucial/Micron, and Samsung. I'll pay more for those 3 brands than I will other brands, because of reliability.

As 250GB low cost I would grab a SanDisk Ultra II.barleyguy - Friday, April 22, 2016 - link
8 of the 48 reviews of that drive on NewEgg are "worked great until it died in a month and I lost my data". As I said in another post, Intel, Crucial, and Samsung are IMO on a different tier of reliability than everybody else.Shadow7037932 - Saturday, April 23, 2016 - link
I like how you're saying Samsung there without considering the issues they've had with the 840. Out of all three you mentioned, only Intel has had solid SSDs since the first gen.barleyguy - Saturday, April 23, 2016 - link
I actually own an 840 Evo in my daughter's laptop. The issues with it never involved data loss or "early death", only degraded performance. Even in its degraded performance mode it still feels faster than a hard drive. And the patches they issued to "fix" it work pretty well to restore it back to SSD-like performance.So, in short, I still trust Samsung on the SSD front way more than Sandisk.
Though I don't disagree that Intel makes excellent SSDs. They're the way to go for a "critical main desktop" type application.

I was going to say that as well. I have an 840 evo in my machine and I haven't lost any data. I regret purchasing it... but it works. The only SSD I've had die so far was a Kingston V100. Still have a couple intel 320 series ssd's running strong, a couple sandisk ones (don't recall the model numbers) that are working and a crucial M500 that is working.Dwedit - Sunday, April 24, 2016 - link
I had the old Intel X25-M, and it had a catastrophic failure where the disk name changed to "BAD CONTEXT" and size changed to 8MB.K_Space - Wednesday, April 27, 2016 - link
X25-M (version 2) still going strong here just not as a main drive since 80Gb is puny. I have both SD Ultra II (960Gb) and 2x Extreme Pro (480Gb) going with no problems. The Extreme Pro was purchased straight after Anadtech glowing review particularly with its 10 years warranty. Not sure what the warranty is for the Ultra II but wouldn't be surprised if its 5+. For every review that says: my SSD died, you'll get a "my SSD is alive & well" so take em with a pinch of salt. It all depends on usage scenario and user expertise and we know how variable that can be.
