The Crucial P1 1TB SSD Review: The Other Consumer QLC SSD
by Billy Tallis on November 8, 2018 9:00 AM ESTBAPCo SYSmark 2018
BAPCo's SYSmark 2018 is an application-based benchmark that uses real-world applications to replay usage patterns of business users, with subscores for productivity, creativity and responsiveness. Scores represnt overall system performance and are calibrated against a reference system that is defined to score 1000 in each of the scenarios. A score of, say, 2000, would imply that the system under test is twice as fast as the reference system.
SYSmark scores are based on total application response time as seen by the user, including not only storage latency but time spent by the processor. This means there's a limit to how much a storage improvement could possibly increase scores, because the SSD is only in use for a small fraction of the total test duration. This is a significant difference from our ATSB tests where only the storage portion of the workload is replicated and disk idle times are cut short to a maximum of 25ms.
| AnandTech SYSmark SSD Testbed | |
| CPU | Intel Core i5-7400 |
| Motherboard | ASUS PRIME Z270-A |
| Chipset | Intel Z270 |
| Memory | 2x 8GB Corsair Vengeance DDR4-2400 CL17 |
| Case | In Win C583 |
| Power Supply | Cooler Master G550M |
| OS | Windows 10 64-bit, version 1803 |
Our SSD testing with SYSmark uses a different test system than the rest of our SSD tests. This machine is set up to measure total system power consumption rather than just the drive's power. The test is run five times in a row on each hardware configuration, and the average scores are reported below.
The creativity and productivity scenarios are relatively unaffected by storage performance, and depend much more on compute power. The responsiveness scores are more dependent on storage performance, but even so the differences between SSDs are fairly small. The Crucial P1 is outperforms the MX500 SATA drive but is a bit slower than the high-end NVMe drives.
Energy Usage
The SYSmark energy usage scores measure total system power consumption, excluding the display. Our SYSmark test system idles at around 26 W and peaks at over 60 W measured at the wall during the benchmark run. SATA SSDs seldom exceed 5 W and idle at a fraction of a watt, and the SSDs spend most of the test idle. This means the energy usage scores will inevitably be very close. A typical notebook system will tend to be better optimized for power efficiency than this desktop system, so the SSD would account for a much larger portion of the total and the score difference between SSDs would be more noticeable.
The energy consumption scores for the SSDs reflect the general trend that higher performance comes with the cost of worse power efficiency. SATA SSDs still lead the rankings for most efficient drive, and the hard drive that's included for comparison purposes required more energy than even the power-hungry Intel Optane SSD 900P.

With worse of everything how is it going to be "faster", do any TLC SSD beat the Samsung MLC ones? No.Valantar - Thursday, November 8, 2018 - link
What's the point of increasing performance when current top-level performance is already so high as to be nigh unnoticeable? The real-world difference between a good mid-range NVMe drive and a high end one are barely measurable in actual real-world workloads, let alone noticeable. Sure, improving random perf would be worthwhile, but that's not happening with flash any time soon. Increasing capacity per dollar while maintaining satisfactory performance is clearly a worthy goal. The only issue is that this, as with most drives at launch, is overpriced. It'll come down, though.JoeyJoJo123 - Thursday, November 8, 2018 - link
^ This.For typical end users, even NVMe over SATA3 SSDs don't provide a noticeable difference in overall system performance. Moving to an SSD over an HDD for your OS install was a different story and a noticeable upgrade, but that kind of noticeable upgrade just isn't going to happen anymore.
Typical end users aren't writing/reading so much off the drive that QLC presents a noticeable downgrade over TLC, or even MLC storage. Yes, right now QLC isn't cheap enough compared to existing TLC products, but we've already done this dance when TLC first arrived on the scene and people were stalwart about sticking to MLC drives only. Today? We got high-end NVMe TLC drives with better read/write and random IOPS performance compared to the best MLC SATA3 drives back when MLC was the superior technology.
Yeah, it's going to take time for QLC to come down in price, the tech is newer and yields are lower, and companies are trying to fine tune the characteristics of their product stacks to make them both appealing in price and performance. Give it some time.

Sure, we lost endurance and speed with the switch from MLC to TLC. But the change from TLC to QLC is much worse in terms of latency, endurance, and just overall performance. Frankly, the sad part is that the drive needs the pseudo-SLC area to just barely meet the lowered expectations for QLC. Some of those QLC drives barely beat good SATA drives.We now have a new tech (3D Xpoint/Optane) that is demonstrably better for latency, consistency, endurance, and performance. I'd rather Micron continue to put the $ into it to get higher yields for both increased density/capacity & lower costs. That's what I want on the NVMe side, not another race to the bottom.

Sorry, you're not the end consumer that dictates how products get taped out, and honestly, if you were in charge of product management, you'd run the company into the ground focusing on making only premium priced storage drives in a market that's saturated with performance drives.The bulk of all SSD sales are for lower cost lower storage options. There is no "race to the bottom", it's just some jank you made up in your head to justify why companies are focusing on making products for the common man. Being able to move from an affordable 500GB SSD on TLC to an similarly priced 1TB SSD in a few years is a GOOD THING.
If you want preemium(tm) quality products, SSDs with only the HIGHEST of endurance ratings for the massive Read/Write workloads you perform on your personal desktop on a day-to-day basis, SSDs with only the LOWEST of latencies so that you can load into Forknight(tm) faster than the other childerm, then how about you go buy enterprise storage products instead of whining in the comments section of a free news article. The products you want with the technology you need are out there. They're expensive because it's a niche market catered towards enterprise workloads where they can justify the buckets of money.
You keep whining, I'll keep enjoying the larger storage capacities at cheaper prices so that I can eventually migrate my Home NAS to a completely solid state solution. Right now, getting even a cheap 1TB SSD for caching is super-slick.

"...how about you go buy enterprise storage products instead of whining in the comments section of a free news article."You are taking this way too personally.
I'm actually thinking more about the business side. I want 3D-Xpoint/Optane to get cheaper & get more capacity so that I can justify it for more than just some specific servers/use-cases. So I'd like Micron to focus more on developing that side than chasing the price train with QLC, which is inferior to what preceded it. With Micron buying out Intel's stake in IMFT for 3D-Xpoint, I just hope the product line diversification doesn't lessen the work to make 3D-Xpoint cheaper & even greater capacities.
JoeyJoJo123 - Friday, November 9, 2018 - link
>You are taking this way too personally.Talk about projecting. Micron is taping out dozens of products across different product segments for all kinds of users. They're working on 3D-Xpoint and QLC stuff simultaneously and independently from each other. What's happening here is that Micron is producing QLC NAND for this Crucial M.2 SSD, and you're here taking it personally (and therefore whining in a free news article comments section) that Micron isn't focusing enough on 3D-Xpoint and that supposedly their QLC is bad for some reason. Thing is, this news article isn't for you. This technology isn't for you. You decided your tech needs are above what this product is aimed for: affordable, large volume SSDs for lower prices.
Seriously, calm down. This wasn't an assault orchestrated by Micron against people that need/want higher performance storage options. More 3D-Xpoint stuff will come your way if that's the technology you're looking forward to. Again back to my main point, it's going to take some time for these newer technologies to roll out. Until then, don't whine in comments sections that X isn't the Y you were waiting for. If the article is about technology X, make a half-decent effort keep to the topic about technology X.

"I'll keep enjoying the larger storage capacities at cheaper prices so that I can eventually migrate my Home NAS to a completely solid state solution."Wwwwwhhhhhhhaaaaaaaaaaattttt?? NEVER. You don't understand the SSD limits. I would not do that with SLC (assuming current quality at QLC price).
Enterprises with SSD NASes only use them for short-term performance storage with hourly/daily backup. Anyone who uses them differently is asking for a disaster.
Look for linuxconf Intel SSD. There is a presentation where they explain how reading a cell damages nearby cells and manufacturers need to monitor this a relocate the data that is only read.
I have 2 servers with only 1 SSD each for OS and 8-10TB HDDs for my actual long-term data.
All my desktops/laptops have SSDs (Intel 320, Samsung 830-860 evo+pro, Crucial BX100/MX300 etc). But anything important on SSDs will be backed-up to HDDs.

"That's what I want ... not another race to the bottom."That's what consumers want: value.
That's not what companies want. They want the opposite. Their wish is to sell the least for the most.
Mikewind Dale - Thursday, November 8, 2018 - link
"[Companies] want the opposite. Their wish is to sell the least for the most."Not true. Companies want to maximize net revenue, i.e. total revenue minus cost.
Depending on the elasticity of demand (i.e. price sensitivity), that might mean increasing quantity and decreasing price.
A reduction in quantity and an increase in price will increase net revenue only if demand is elastic.
But given the existence of HDDs, it makes sense that demand for SSDs is elastic, i.e. price-sensitive. These aren't captive consumers with zero choice.
Of course, nothing stops a company from catering to BOTH markets, i.e. high performance AND low cost markets.
