The ADATA XPG SX6000 Pro 1TB SSD Review: Realtek's Entry-level NVMe Solution
by Billy Tallis on December 18, 2019 12:30 PM 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. 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.
The ADATA XPG SX6000 Pro has the worst overall performance on the Light test out of all the NVMe drives in this batch, though several drives with better peak performance are slower when the test is run on a full drive.
The average and 99th percentile latency scores for the SX6000 Pro are high for a NVMe drive, but it doesn't lose much performance when the test is run on a full drive so those worst-case scores are still better than the SATA drives. Most of the other low-end NVMe SSDs can degrade to SATA or worse performance.
The average read latency of the SX6000 Pro is strongly affected by the drive being full, while the average write latency is completely unaffected. None of the other low-end NVMe drives keep write latency so low when the test is run on a full drive.
The 99th percentile read and write scores for the SX6000 Pro are all good, but the solid write QoS even for a full drive is impressive.
The energy usage of the SX6000 Pro over the course of the Light test is again roughly twice that of the other DRAMless NVMe SSDs, but it's not particularly high when compared to NVMe SSDs in general.

I don’t think you are being critical enough of this drive. It is appallingly bad. It’s basically outclassed by SATA drives from years ago in almost every metric except sequential performance (where NVMe will naturally excel)But real world performance is terrible, power usage is high (and it has broken devsleep) and it isn’t very cheap. When you consider reliability is a total u known I’m struggling to imagine a single person who would consider this.

Let me make it a bit clearer for you: https://www.anandtech.com/bench/product/2533?vs=22...The MX500 beats the SX6000 Pro on just ONE of those performance metrics. The picture's not that different if you compare against a Samsung SATA drive. Overall performance is clearly much better than a SATA SSD. It's not appallingly bad. It just isn't a high-end NVMe drive.

Appallingly Clearer. : )Alistair - Wednesday, December 18, 2019 - link

Based Billy Tallis *dabbing* on the n00bs in the comments section. FACTS don't care about your feelings, Samus. It's times like this I'm glad you can't edit your comments, since moments like these are eternalized forever.MFinn3333 - Wednesday, December 18, 2019 - link
To be fair, the Samsung 850 Pro does beat it in the sustained random read/writes, power efficiency of said read/writes and uses a lot less power while active idle.https://www.anandtech.com/bench/product/2310?vs=25...
(Blue is Samsung and Orange is ADATA because Samsung is blue in my mind).
To be fairer, the Samsung is at least five years old, costs three times as much if you can get it, and has an idle response that is 15X worse than the ADATA. The ADATA is clearly the better drive for 99% of the population.

It's absolutely appallingly bad. You can't simply excuse broken power management with "the other vendors messed it up too", the point is that none of those other vendors have messed it up NOW. Realtek failed to learn from and avoid their competitors' mistake, and by doing so have introduced their controller with a handicap versus the same competitors. It's also both unproven, slower, and more expensive than older controllers that do have a known track record, so that's four strikes against the RTS5763DL.In contrast, drives using the two-year-old SM2263XT are faster, cheaper, and to be blunt, just better. There is thus no reason why anybody would ever choose a drive using RTS5763DL, and its complete failure to compete is only going to become more apparent once the next-gen SMI and Phison controllers arrive (and E12 products go EOL and get huge discounts).
In short, while not as bad as Realtek's attempt at a SATA SSD controller, the RTS5763DL is just a plain bad product that simply cannot be recommended in any way shape or form.

Well look at this one again then: https://images.anandtech.com/graphs/graph15139/sus...I've learned from real-life usage that this test is one of the most important metrics that you will notice in your day to day usage. The Realtek is by far the fastest cacheless NVMe controller out there in this test.
Also while the drive lacks DEVSLP, statements like "broken power management" are just false. The graphs clearly show that it cuts power in half in each state. Lacking DEVSLP does not equal broken power management. ADATA even clearly states this on their website.

well... I installed the xpg Gammix s41 which is based in the same microcontroller! I lost more than an hour of battery life in my laptop and now sleep mode is basically useless. One big mistake in my part was caring only about read and write speeds. I can't wait to replace this drive, its driving me mad!mark625 - Wednesday, December 18, 2019 - link
The HP EX950 1TB has been my favorite value/$ drive for a while, and it costs a whole $7 more than the SX6000 Pro. It whomps the XPG drive in almost every test, and in many tests it is more than twice as fast.In what possible scenario would the XPG drive be a smarter purchase than the HP? None that I can see. This review is way too forgiving.
