The SK Hynix Gold S31 SATA SSD Review: Hynix 3D NAND Finally Shows Up
by Billy Tallis on November 13, 2019 12:00 PM ESTIdle Power Measurement
SATA SSDs are tested with SATA link power management disabled to measure their active idle power draw, and with it enabled for the deeper idle power consumption scores and the idle wake-up latency test. Our testbed, like any ordinary desktop system, cannot trigger the deepest DevSleep idle state.
Note: Earlier this year we upgraded our power measurement equipment and switched to measuring idle power on our Coffee Lake desktop, our first SSD testbed to have fully-functional PCIe power management. The below measurements are all new, and are not a perfect match for the older measurements in our previous reviews and the Bench database.
The active idle power consumption of the SK Hynix Gold S31 SSDs is among the best we've seen from SATA drives, though the largest 1TB model requires slightly more power than the two smaller models. When SATA link power management is enabled, power consumption ends up being merely the typical values for mainstream drives.
The idle wake-up process takes the S31s about half a millisecond, plenty fast and a factor of two better than other mainstream drive latency.

We're not going to get under 10c/GB anytime soon, will we? SATA SSDs seem to be stagnant - performance is OK, power consumtion is OK, price is $100 for 1TB, endurance is the usual 0.3 WPD - and yet there are constantly new products with different components and basically the same performance/power/price.Is there a limitation that currently causes stagnation? (I know that SATA is inherently limited in performance, but price shouldn't be stagnant if the main need in that sector is more capacity for less money, with performance/power/endurance being the same)

"price shouldn't be stagnant if the main need in that sector is more capacity for less money"all of these companies face the Tyranny of Fixed Cost, i.e. the BoM is almost all amortization of the plant and equipment to make the various bits and pieces. sand, some chemicals, and a watchman or two to hover over the machines amount to the variable cost. in such a situation, the only way to lower *average cost* (and shut up the bean counters) is to ship more product and thus spread the fixed cost a tad thinner. lots more product. but that, in turn, is strictly limited by user demand. they're caught between a rock and a hard place. they end up viewing the situation as zero-sum game; one can win only if the other(s) lose when there's little to no global (in every sense of the word) growth. welcome to Earthly Stagnation.

Having Dr ManHattan looking after your machines is a very expensive business , Rorschach is very unreliable too.eek2121 - Wednesday, November 13, 2019 - link
Except prices have been falling. You just don't realize it because it happens over time.These drives are as cheap as Samsung's QLC drives, without the disadvantages.

SSD prices have been basically flat since October/November 2018. Check the price tracking for a 500GB/1TB MX500 or 860 Evo and there have been a few variations but nothing substantial or permanent.I'd love to pick up more large capacity solid state to replace some of my HDDs, but I bought two 2TB SSDs over a year ago and they're actually a few dollars *more* expensive now.
At this point, it may actually be cheaper to build a large NAS using MicroSD cards...

I paid the same amount for my 2 TB 970 evo as I did my 1 TB 960 evo 2.5-3 years ago. Also, don't track specific drivers, look at charts. NAND is coming down. It just takes time.Slash3 - Wednesday, November 13, 2019 - link
/s implied with respect to the MicroSD card NAS, if it weren't obvious.Although that would be fun to build.

Sale prices are hitting 8c/GB. Don't pay 10c/GB if you live in America. As the average drive capacity goes up, the prices will continue to go down.Thankfully, 100 GB and larger games are a thing, so that should create some demand.

we might PLC coming soon, so we might see some 1 TB/1.5 TB/2TB/3TB sata's soon and as they are 20% bigger after amortization wears off, almost 20% cheaper it will become.main focus will go to PCIE4.0 now though. so I would say next December expect 2 or 3 products with same nand. 120GB/240 will not go lower than its is now.
deil - Thursday, November 14, 2019 - link
in there on the article. We already did on 1 TB ones. and PLC will go even lower.ADATA SU800 $34.99
(14¢/GB) $57.99
(11¢/GB) $91.99
(9¢/GB) $209.99
(10¢/GB)
