Announcing the TechPowerUp SSD Specs Database
We are announcing the latest addition to our PC enthusiast databases, the new TechPowerUp SSD Specs Database. Modeled along the lines of our immensely popular GPU Database, CPU Database, and hardware Reviews Database, the new SSD Specs Database, curated by Gabriel Ferraz, aims to be a definitive repository of information on solid-state drive (SSD) hardware specs, for all to freely access. Here, you'll find a growing collection of client SSD hardware specs across all relevant form-factors and information. The database also helps you identify multiple hardware revisions of the same SSD model, so you're aware of any bait-and-switch incidents, or vague specs by manufacturers.
The TechPowerUp SSD Specs Database has individual info pages on each capacity variant of an SSD model; besides any hardware variants it may have. You can have quick, actionable information on specs such as controller, NAND flash, DRAM cache, advanced NAND flash specs, interface, protocol, controller hardware specs, and known performance numbers from our testing. We are constantly adding new drives to this database, and you can help us grow, not just by suggesting improvements to the database itself, but for additions to the database, please reach out to the curator on the main page. But for now, enjoy what we've built for you!

hey @Wirko Check it out.

The following picture is a Samsung MLC 32Gb 32nm Die from Samsung, the ones used in the Samsung 470 series
I see just a small error in the database, the block size is 1024 KB or 128 pages, not 1024 pages.
Those old chips, they had fully binary organisation, there was 2^n of everything. It's quite different in new ones.
Corrected
It actually much harder to find data on these older dies then newer ones lol
*Hysterical crying*

Ended up with 6 of the bloody things, good thing they're somewhat decent
What we need now is an SSD chart like the GPU one, showing loose performance comparisons...
I'll accept donations of one of every SSD ever, and work my way through if needed
It might be tough to do it since SSDs are more susceptible to have performance impact if you change the testing platform like Intel x AMD, and even if we use our own testing data which W1zzard has over the years, it would still be missing literally hundreds of drives.
The issue is, if the controller is proprietary you won't be able to run it.
Only controllers like, Phison, Silicon Motion, Innogrit, Maxiotech etc
With the exception of the latter, because NDAs likely prohibit, it takes a bit more time to find the right stuff. :)
I'm glad I could help!
If you find any other feel free to mention me :D
I love how WD hide certain stats on some drives, try finding the TBW on their kamikazee drives aka the WD greens
"1 million hours" and a few asterisks
SSD-Z name was already tried by someone in the past, but we need a TPU-Z program that can read these details like GPU-Z does and upload specs to be verified
It could be like userbench, without being shit! :D
But you can also reach-out to me if you're having a hard time finding more info on a drive, just mention the model and I'll see what I can do. :)You'd think that they actually test that thoroughly? :laugh:
I see that the same Intel's controler was used in several other SSDs, including enterprise models, so there's a high probability that the same NAND dies went into those too.
The controller is Intel PC29AS21BA0, at least in the 160 GB model, and it's a 10-channel controller. A funny model number I must say, since "29" was reserved for EEPROM chips and all their ilk, including NAND, sincer ever at Intel. Just like 27 was EPROM, 82 were/are peripherals, and we all know 80.
Edit: not entirely true, the 320 (consumer) and 710 (enterprise) SSDs had the same controller but 25 nm NAND.
Look at what i found... hahah
Since i now have more in depth data from these dies, i can surely add the Intel X25-M G2 with more reliable data.i'll try to find more data on the controller now and then move to add them to the database.
He's probably referring to the same 25nm type of die that's also found in the Intel 320 (consumer) and 710 (enterprise) SSDs, also analysed and compared here by Tom's Hardware. HET means High Endurance Technology, which means whatever Intel tells us or doesn't tell us. They had to reveal at least some info because back then it was necessary to convince enterprise users that MLC can be trusted.
As it appears, the 710 has better binned dies, writes at lower speeds (so it can charge the cells with more precision), and also writes at lower voltages. On top of that, it has an incredible amount of overprovisioning: 320 GB raw, 200 GB available. All that was supposed to result in 33x more rewrite cycles than in the consumer-oriented 320.
I believe SSD manufacturers still have to make similar compromises today: higher write speed and lower endurance, or the other way around.
For example, get the Samsung 990 Pro, the 2TB have 32 dies of Samsung V7 512Gb 176-Layers, these dies in a day to day scenario can beat 150-160MB/s of write throughput. So 32 dies x 150 MB/s = ~4.800 MB/s
But as you can see in the graph below, the Drive writes at an average of 1.4 GB/s
They did that to not only increase endurance (probably) but to generate less heat output and a higher efficiency (MBps / watt)
It doesn't mean that after that time your data simply becomes unrecoverable, there's still ECC. :laugh:
Really comes down to how the PCB is done, but regardless of that, it's worse for higher layered NAND.
Too bad SLC/MLC SSDs for lower capacities aren't a thing anymore, besides halo products. :oops:
The Transcend 370S was the last one I could find "widely available", being MLC, back in 2018. And I say it this way because I could find them at a few stores, but those had little stock and had them costing a small fortune for 512GB.
but jesus, those are extremely expensive
