AnandTech 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. As with the ATSB Heavy test, this test is run with the drive both freshly erased and empty, and after filling the drive with sequential writes.

ATSB - Light (Data Rate)

The ADATA XPG SX950 continues the trend of being reasonably fast when fresh, but much slower when full. Its average data rate on the Light test is almost as fast as the Samsung 850 Pro when the test is run on an empty drive, but when the drive is full it returns the lowest average data rate score in its class.

ATSB - Light (Average Latency)ATSB - Light (99th Percentile Latency)

There usually isn't much to look at in the latency results for the Light test; most SATA drives perform very similarly. The ADATA SX950 is normal when the drive is fresh, but when the drive is filled before running the test, the results are very unlike any other SATA SSD we've tested. With a 99th percentile latency of over 30ms (dwarfing the Crucial MX300's 6.5ms), it's clear the SX950 does not manage its background processing properly.

ATSB - Light (Average Read Latency)ATSB - Light (Average Write Latency)

The Light test is easy enough that the average read latency of the SX950 is normal whether or not the drive was filled before running the test. The average write latency is still several times higher in the full-drive case, and is twice that of the next-slowest drive in this bunch.

ATSB - Light (99th Percentile Read Latency)ATSB - Light (99th Percentile Write Latency)

As with the average latency results, the 99th percentile read latency of the SX950 is not appreciably higher than normal when the Light test is run on a full drive, but on the write side latency is out of control. The Crucial BX300 has a substantially higher 99th percentile write latency when the test is run on an empty drive, but it doesn't go to pieces when the test is run on a full drive.

ATSB - Light (Power)

Energy usage by the ADATA SX950 is again quite good when the test is run on an empty drive. When the drive is full, the energy usage still falls within the acceptable range, but is unimpressive.

    Oh dear God, another SSD that has absolutely no reason of existence. Really bored to see another SSD that gets pwned by 850 EVO (leave the PRO). I wonder if manufacturers actually test and benchmark their products before driving them to market.

    Sadly, very little of what humans do is because it is necessary or it makes sense.

    @ddriver And yet you continue posting...

    Moot point, as I don't identify with the human herd. Cattle mentality and the accompanying irrational behavioral patterns don't sit well with me. Which is also why I refer to humans in third person, a subtle nuance an intelligent person would have read into.

    But not you though, you perfectly fit the profile, seeing how once again you fail at getting stuff or making sense ;) But still, an understandable effort, you are probably still hurting by that chain of pwnage. And it's only parroting cliches because you really cannot do better.

    You humans, sometimes I am amazed you made it this far. And since you wouldn't get the nuance, there are two contexts to that, the first being that you still haven't succumb to your stupidity, and the second being "this far into devolution". I suppose that's why you cherish the establishment and its mediocrity so much, even if it is what pushes you to regress into cattle, you still get to survive, suckling at its toxic tit. It's your mommy, that's what your infant mind can identify it as, not as what it really is.

    And just in case you are perplexed how me responding to your post is something that makes sense, since you obviously can't get all this, it is quite simple - you are not the intended audience, just the means of making a point for the occasional few that can get it ;)

    This quote "Sadly, very little of what humans do is because it is necessary or it makes sense," is a telling feature reveal of this AI Cyborg miscreant, who apparently has a deep rooted need for focusing on humans, describing humans, engaging humans, belittling humans; and it's apparent its existence and glorified self aggrandizement is defined solely on the existence lowly humans, as evidenced by the closing statement "you are not the intended audience ...".

    Sadly, very little of what this AI cyborg does makes sense. Prattle over product reviews is merely pretense of know how . Sadly no one has yet found the power down switch for this AI cyborg. For as much as it exudes disdain for humans, yet its very reason for being relies entirely on the necessity for engaging with them, to establish meaning in its miserable existence. These posts are its food, and a belittlement posture its means of self aggrandizement compensating for its low class software programming. The prattle is evidence that surely this really is no human (as it itself claims). It needs a firmware upgrade and an implant to put it out of its misery. I wish scientists would stop creating such experimental specimens for their own misguided research.
