AnandTech Storage Bench - Heavy

Our Heavy storage benchmark is proportionally more write-heavy than The Destroyer, but much shorter overall. The total writes in the Heavy test aren't enough to fill the drive, so performance never drops down to steady state. This test is far more representative of a power user's day to day usage, and is heavily influenced by the drive's peak performance. The Heavy workload test details can be found here. This test is run twice, once on a freshly erased drive and once after filling the drive with sequential writes.

ATSB - Heavy (Data Rate)

The Silicon Power P34A80 is slightly faster overall than the Corsair MP510 with the older Phison E12 firmware, both when the Heavy test is run on an empty drive and a full drive. The improvement in full-drive performance is smaller but more significant given that the P34A80 has a larger usable capacity and thus smaller spare area to work with.

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

The average and 99th percentile latency scores for the P34A80 are better than the Corsair MP510 and competitive with the fastest TLC-based SSDs.

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

The average read latency from the P34A80 is about the same as from the Corsair MP510, and slightly slower than the fastest TLC-based SSDs. The average write latency is better for the P34A80 than any other TLC SSD.

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

The 99th percentile read and write latency scores for the P34A80 are very similar to the average latency scores: read performance is essentially unchanged from the older firmware, but write latency is better, especially when the test is run on an empty drive.

ATSB - Heavy (Power)

The P34A80 is again a bit less efficient than the Corsair MP510 with slightly higher energy consumption over the course of the Heavy test, but the P34A80 is still clearly in the more efficient tier of drives.

    5 year warranty is pretty good for the price.

    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.

    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.

    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.

    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.

    Ta for the heads up. am now leery of SP. that stuff is not cricket (kosher).

    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.

    I misposted this -

    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...

    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!
