Previewing Maxiotek's MK8115 SSD Controller: Can DRAM-less Drives Make The Cut?
by Billy Tallis on May 9, 2017 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 Light test shows a narrower spread of scores than the other ATSB tests, but the MK8115 drives are in last place with average data rates slightly below their respective OCZ competition, and they trail by a slightly wider margin when the test is run on a full drive. The fastest MLC and TLC SATA SSDs (from Samsung) are 20-25% faster.
Average service times from the MK8115 samples are on par with other SATA SSDs when the test is run on an empty drive, but when the drive is full service times more than double and are substantially higher than any other SSDs.
The number of high-latency outliers above 10ms experienced by the MK8115 drives when the Light test is run on an empty drive is typical for other SATA SSDs. When the drives are filled before the test, the MK8115 with MLC is affected significantly but not as much as drives like the Crucial MX300 or OCZ VX500. The MK8115 with TLC does far worse and ends up almost three times as many outliers as the next worst-scoring drive (the ADATA SU800).
Power consumption for the two MK8115 drives on the Light test is very similar and slightly better than average. The SATA SSDs that consume substantially more power are Samsung's high performers and the two drives using the Phison S10 controller.

I fondly remember when new developments in SSD products resulted in lower prices AND better performance. Now it seems that every new product is geared only for lower prices, and the performance is getting worse! Not to mention that the prices have gone up substantially in the past year, I don't think we are at the best value time for SSD's.MajGenRelativity - Tuesday, May 9, 2017 - link
Can you provide evidence of performance getting worse? I haven't seen groundbreaking performance strides in anything but high-end/upper-mid (Samsung 960 series), but I haven't seen a performance regression.Sonic01 - Tuesday, May 9, 2017 - link
i actually found this today, i was looking for a new budget 1tb SSD.my current is a crucial m500 from 2013 i bagged for about £450, now the cheapest 1tb ss'd are about £300 but overall performance is about 30% of the m500..... in 4 years they have dropped 30% of the cost at the expense of 60% of the speed...

I looked on amazon.co.uk and the Samsung 850 Evo is 300 for 1TB. I also paged around in Anandtech reviews, and it has better performance than the M500, sometimes significantly so. The MX300 is 250 for 1TB, and it also scores very well on reviews, although I didn't do a very thorough comparison to the M500, it seems a little lower in performance compared to the 850Evo, which should still put it slightly ahead of the M500AlphaBlaster - Sunday, May 14, 2017 - link
That embecil Comey wanted to grab and be in the headlines, and he was manipulating evidence, etc ,and non-evidence, etc.to accomplish that. That's just one thing. He has no integrity. He showed himself to be just another Washington stooge. Hoover was also another Washington stooge and a degenerate, but was fired by the president that committed the crime that he fired Hoover for. If some entity could lob a couple of nukes onto Washington DC when whatever worthless miscreant president at the time is addressing both houses of congress, it would be a blessing!CheapSushi - Wednesday, May 10, 2017 - link
The big difference is the Crucial M500 is MLC NAND and the Samsung 850 EVO and similar cheaper ones are TLC NAND. TLC is inherently slower than MLC; always. It's 2 bits per cell vs 3 bits per cell. It's an important distinction when comparing SLC, MLC, TLC and soon QLC. Maybe you didn't know?extide - Wednesday, May 10, 2017 - link
Yeah, but the 850 is also using #d TLC, not planar TLC, and 3D TLC is a lot faster than planar TLC. Maybe you didn't know?extide - Wednesday, May 10, 2017 - link
#d is supposed to be 3D, of courselowlymarine - Wednesday, May 10, 2017 - link
If only the very site you were on had some sort of database of benchmarks you could check to see that, in fact, the 850 EVO is massively faster than the M500. Oh hey, look what I found! http://www.anandtech.com/bench/product/805?vs=1398MajGenRelativity - Thursday, May 11, 2017 - link
The 850 Evo is faster though, so I'm not sure what you're trying to say
