The SK Hynix Gold P31 NVMe SSD moves the needle on the industry seismometer most attractive ample to make this evaluate some distance more straightforward to write. Two parts alter the needle’s route: The P31 is now not most attractive the first pressure to sport 128-layer TLC NAND, it’s furthermore the first in my skills to characteristic eco-friendly packaging. Huzzah!
This evaluate is share of our ongoing roundup of the most straightforward SSDs. Fling there for recordsdata on competing merchandise and how we examined them.
On August 31st, 2021, SK Hynix sent us the newly launched 2TB model of the Gold P31 (
$280 on Amazon). In testing, the efficiency used to be interior half of a pc either formulation of the 1TB model reviewed right here, which used to be first printed on August 19, 2020. Make and specs
While the SK Hynix Gold P31 uses the identical 2280 (22 mm huge, 80 mm long) make allege as most SSDs, the similarities cease there. As a replacement of the typical 96 layers of TLC NAND, the P31’s TLC NAND sports actions 128. How this translates to “4D,” because the company refers to it in the product brief, moderately than 3D, I’m now now not sure . There’s DRAM cache on board, and NAND is employed as secondary cache, despite the truth that we have been now not given the portions enthusiastic. No topic they’re, they’re efficient.
Regardless, it’s a first and translates to extra reminiscence per chip and lower prices: The 1TB capacity we examined is $135 on Amazon, whereas the 500GB is $75 on Amazon . A more modern 2TB models prices $280. There are cheaper drives, you divulge? Determined, by a little bit, but be taught the efficiency share under.
SK Hynix’s P31 delivers top-notch efficiency at a bargain discover.
The P31 carries a five-twelve months guarantee, a 1.5- million hour-MTBF (Suggest Time Earlier than Failure) ranking, and 500TBW ranking for the 500GB and 750TBW for the 1TB which shall be bigger than first fee numbers. That info affords us a sunny outlook on the lifespan of the pressure, despite the truth that if truth be told, SSD failures are practically unprecedented in the tip-particular person plan on the brand new time.
I must once extra mention the eco-friendly packaging. In a worldwide the achieve every product appears to be like to add one other layer of detritus to landfill, the P31 is a nice exception. I won’t discuss e-spoil—that would waste the temper.
The 1TB P31 I examined entirely acceded the CrystalDiskMark 6 and AS SSD synthetic benchmarks. It hit virtually the 3.5GBps be taught and write speeds claimed in the clicking open. Halt ample to call it moral, given that our testbed is several generations identical outdated.
The SK Hynix P31 is appropriate there with the tip dogs in CrystalDiskMark 6. Longer bars are larger.
Throw out the dinky file be taught take a look at, and the P31’s aggregate ranking would come across great, severely larger. I ran the take a look at an additional five cases to verify the seemingly oddball consequence. Shorter bars are larger.
The P31 redeemed itself with a mighty efficiency writing our enormous 450GB file. Here’s now now not one thing users in general attain, but it certainly is an moral take a look at cache management, and each every so frequently NAND speed. Be conscious the moderately grim outcomes grew to alter into in by the Vital P5 and Samsung 970 EVO Plus. That’s what occurs whenever you high-tail out of cache. We’ve considered even worse from bargain drives.
The SK Hynix P31 practically matched the mighty Seagate FireCuda 520’s time on this take a look at. Ample, now not lower than compared with the Vital P5 and 970 EVO Plus. Shorter bars are larger.
Show that you just won’t get barely the identical efficiency out of the 500GB P31, severely whenever you stir off cache. Nonetheless, the claimed efficiency says it will live sprightly, with the exception of staunch via the 450GB write, the achieve it can plunge to 950MBps and steal commensurately longer.
Testing is performed on Dwelling windows 10 64-bit running on a Core i7-5820K/Asus X99 Deluxe plot with four 16GB Kingston 2666MHz DDR4 modules, a Zotac (Nvidia) GT 710 1GB x2 PCIe graphics card, and an Asmedia ASM2142 USB 3.1 Gen 2 (10Gbps) card. Additionally on board are a Gigabyte GC-Alpine Thunderbolt 3 card and Softperfect’s Ramdisk 3.4.6, which is similar outdated for the 48GB transfer tests.
An just steal
The SK The Hynix Gold P31 performs cherish a top-tier pressure, but it certainly’s priced factual a little bit elevated than bargain drives. That, my friends, is a real bargain. If 1TB or 2TB of capacity meets your desires, transfer this to the tip of your checklist.
Editor’s repeat: This text used to be edited a number of hours post-open to moral the TBW ranking for the 500GB pressure to 500TBW from 350TBW, based mostly on recent recordsdata supplied by SK Hynix.
