AnandTech Storage Bench - The Destroyer
The Destroyer is an extremely long test replicating the access patterns of very IO-intensive desktop usage. A detailed breakdown can be found in this article. Like real-world usage, the drives do get the occasional break that allows for some background garbage collection and flushing caches, but those idle times are limited to 25ms so that it doesn't take all week to run the test. These AnandTech Storage Bench (ATSB) tests do not involve running the actual applications that generated the workloads, so the scores are relatively insensitive to changes in CPU performance and RAM from our new testbed, but the jump to a newer version of Windows and the newer storage drivers can have an impact.
We quantify performance on this test by reporting the drive's average data throughput, the average latency of the I/O operations, and the total energy used by the drive over the course of the test.
The Silicon Power P34A80 is insignificantly slower on The Destroyer than the earlier Phison E12-based drive. Both still rank as slightly slower than other high-end drives that use the same Toshiba/SanDisk 3D TLC, and significantly slower than the fastest TLC-based drives. However, the Phison E12 handles The Destroyer better than the Silicon Motion SM2262EN and offers more than twice the overall performance of the entry-level NVMe drives or Phison's first attempt at a high-end NVMe controller.
Average and 99th percentile latencies on The Destroyer have both regressed slightly with the newer Phison E12 firmware used by the P34A80, but it is still clearly delivering performance that places it in the top tier of high-end NVMe drives.
The average read latency on The Destroyer is unchanged by the new Phison E12 firmware, but the average write latency is no longer a stand-out winner. Instead, the P34A80's average write latency is merely on par with the other top NVMe drives on the market.
The 99th percentile read and write latency scores for the P34A80 are both worse than those from the Corsair MP510, but not by enough to knock the P34A80 out of the top tier of drives.
The energy consumed by the P34A80 over the course of The Destroyer is slightly more than that used by the Corsair MP510, but both are more efficient than most NVMe SSDs.

5 year warranty is pretty good for the price.XabanakFanatik - Friday, March 1, 2019 - link
Where did these mysterious benchmark results in the charts for the 970 PRO 1TB come from? There still hasn't been a review posted for it.IndianaKrom - Sunday, March 3, 2019 - link
I noticed that as well, and I actually have a 970 Pro / 1 TB. I got it a couple months before the 970 EVO Plus was announced and was kind of kicking myself for spending more on it figuring the EVO Plus was probably the same or better performance for less, but turns out the Pro still reigns supreme in everything but burst writes.Luckz - Wednesday, December 4, 2019 - link
Note that those are now likely made with E12S instead of E12, half the DRAM, and 96L instead of 64L flash, so performance will vary and be worse in some use cases than what is reviewed here.schevux - Monday, January 6, 2020 - link
Hey what do you mean by that ? How much the performance would change ? I am considering this over 970 evo by these benchmarks but if the performance would be worse i would go with 970 evo. Thanks.msroadkill612 - Monday, May 18, 2020 - link
Ta for the heads up. am now leery of SP. that stuff is not cricket (kosher).quakerj - Saturday, January 11, 2020 - link
I would get the 970 Evo. I ordered a 1TB P34A80 and received it today. It is nothing like what has been reviewed here. Flash chips have the marking "Unic2 UNN1TTE1B1JEA1." I think that's Chinese flash, Google isn't very helpful other than providing a link to Unic2 flash manufacturer, a Chinese website. Additionally my card contains Nanya DDR3 DRAM modules, not DDR4 like the reviewed model. Seems like a classic bait and switch. It's getting sent back to Amazon in a fast second, I would avoid like the plague.msroadkill612 - Monday, May 18, 2020 - link
I misposted this -Ta for the heads up. am now leery of SP. that stuff is not cricket (kosher).
i cant see why a noname cant do a decent e12 product, but not this thanks.

For what it's worth, a major redesign warrants a new model number or revision suffix. If you go and buy this, it's not going to perform like the reviewed model, there are simply too many changes. It'll be a fast SSD no doubt, but I think SP pulled a fast one here and should be more transparent about the changes. They still advertise all these [original card] reviews on their website as though you're going to receive the same product. Just my humble opinion...Mueller - Wednesday, April 22, 2020 - link
This is really an excellent read for me, Have to admit that you really are one of the greatest bloggers I ever saw. This platform is really useful for those who interested in technology. I prefer to play blackjack on https://interactivecasinos.org/casino-games/blackj... In this case, the most important thing is to choose a reliable bookmaker on the site Read reviews on the best!
