Pete 12 Posted December 18, 2020 Share Posted December 18, 2020 In the previous Crystal Disk-version , from 8.8.9 , we could see the health of our Samsung SSD in procents ( mine is showing ; GOOD / 96% ) In these latest versions ; 8.9.0 and 8.9.0a , it only shows " GOOD" .........so no procents of health anymore !! Very dissapointing , these two latest updates ...........will stay on 8.8.9 , untill they will fix this failure. Im sure , a lot of Samsung SSD-fox will not like it either................. Anyone has another fix for showing procents in latest versions ?? Link to comment Share on other sites More sharing options...
random Posted December 18, 2020 Share Posted December 18, 2020 It's practically still there. Yes it's an annoying choice without much meaning, but the SMART attribute to monitor is still there and properly monitored. Wear Leveling. Link to comment Share on other sites More sharing options...

Pete 12 Posted December 18, 2020 Author Share Posted December 18, 2020 " Wear Leveling ".............does not give us a real indication about our SSD-health ! It should be in procents still ............how much procent is " Wear Leveling Count 21 " ?? Just dont see the profit of taking this info away , will stay at 8.8.9 anyway ............

Wear Leveling is what determines the remaining health of the SSD for these SATA Samsung drives. The percentage is right there, 99% in my image. Depending on drive size and NAND type, you'll drop a percentage a few leveling cycles. The 3D V-NAND on the 850/860 EVO drives is likely rated for 2000 WL cycles, according to Anandtech's calculations. If it's a pro with MLC instead of TLC on Evo, it'll be rated higher. If you really want to see the percentage, you can download Hwinfo64, or AIDA64. Both still offer the number. As for why it was "removed", even though it's there in plain sight, only the CDI dev knows. But it sure is weird. My 970 Evo+ NVMe drive still shows the percentage, then again, that drive is not using a Wear Leveling metric, but "Percentage Used" I think. It should still have a WL hidden attribute though, as this is how NAND SSDs work. Link to comment Share on other sites More sharing options...
rseiler Posted December 19, 2020 Share Posted December 19, 2020 It's not a bug but a feature: "Deleted Samsung SATA SSD Life report" I wonder if they have any kind of forum where it might be explained. Link to comment Share on other sites More sharing options...

Pete 12 Posted December 19, 2020 Author Share Posted December 19, 2020 " mine is showing the correct version " .............strange ; your Wear Leveling shows ; 87 and 98 % still........ Mine Wear Leveling shows ; 96 with 96 % ( on version 8.8.9 , later versions dont show procents at all !! ) Gues it depends on the type SSD you use..............(??)

random Posted December 19, 2020 Share Posted December 19, 2020 Each manufacturer uses their own remaining lifetime approximations, so SK Hynix won't use the same algorithms as Samsung. But for SATA Samsung SSDs, which were the only ones mentioned in the changelog, the WL attribute is easy to correlate with the remaining lifetime. It's worth noticing that these SSDs will likely last for a long time after the remaining lifetime reaches 0%. This is not an exact science, it's just the estimation for how many program/erase cycles (P/E cycles) the NAND cells can endure, in average. But actual tests have shown that the Samsung NAND on the 850-860 series will last for far longer, especially for larger drives. A 256 GB 850 Pro lasted for 7 Petabytes written, for example, before dying. A 850 Evo for about 2 PBW. So monitoring the remaining life is largely pointless for newer TLC/MLC drives and you should probably just not bother. QLC drives can be a bit more problematic, I've seen some testing where an Intel drive died on 100GB written, but that is likely to have been improved significantly in newer versions. I personally monitor my drive because I like to dig into this stuff and see how things work, but at the pace I am writing to my 850 Evo it'll last for decades, and by then it'll be long obsolete. For example, my drive drops 1% of estimated lifetime per about 15-16 WLs. Each WL cycle seem to occur at around 600-700GB written. That means the drive is likely meant to last for 1500 P/E cycles before it reaches 0% and it should write a bit under 1 PB before that point. That is far above the 150TB Samsung guarantees and the 5 yr warranty. And the drive won't just die at that point, it will just start to replace sectors that fail from its reserves and correct errors as they appear. If you want to make the drive last even longer, just use overprovisioning. Samsung's Magician has a function for it, but it's essentially just a space left unpartitioned at the end of the drive. I've set mine to 10% on both the 970 Evo+ and the 850 Evo. Link to comment Share on other sites More sharing options...
Pete 12 Posted December 19, 2020 Author Share Posted December 19, 2020 210GB available of the 250 Samsung SSD , no indexing , no backups on it , etc and using SSDFresh for keeping the SSD in topform .......... So , it has to function for a very long time indeed. When time comes , have to replace it with the 860 EVO , hope I can do this by copying a MR-image on it.

By the time you need to replace your 850 pro there will be cheaper NVMe alternatives and you'll probably have changed the PC too. And if you have an older PC without M2 slot, just buy a PCIe card so you can use the M2 format drives. We'll be at 990 Evo or w/e by then. Not that Samsung is the only worthy manufacturer, I got Samsung drives cause I caught them on heavily price reductions, but Sabrent Rocket and the sort are really good variants. Also some Adata drives. SATA is pretty much dead by now, other than mass storage. PS: you definitely can stop worrying about things like indexing and SSDFresh, Windows 10 and the SSD firmware does all that's needed Hibernating is a bit annoying yeah, I turn it off myself, because it writes large chunks of data worth a few GBs on shutdown, and it's not worth it when you boot from SSD. Overprovision some of the drive, turn off hibernation, and leave the rest to Windows. Link to comment Share on other sites More sharing options...

UberGeek Posted December 29, 2020 Share Posted December 29, 2020 Just a heads up for those who might own a old system (PC) and be planning to upgrade their SSD to an M.2 format NVMe mounted on a PCIe adapter; so that the upgraded NVMe could be used as a system (boot) drive. Most NVMe SSDs would be able to be used merely as a storage or secondary drive. There are some very rare NVMe drives such as the 950 Pro SSD which can be used as a system (boot) drive. This is possible with this unique disk since the controller chip of the the 950 Pro contains its own Option ROM module which supports NVMe. If the motherboard does not support NVMe though, the BIOS would need to be modded to accommodate at the very least . . . Option ROM module for NVMe support in order to enable boot from the PCIe adapter. There are other alternatives to the BIOS mod such as Clover bootloading and dual-booting from a flashdrive. ps: The screenshot on my previous post was generated from a PCIe-mounted NVMe on a 9-year old PC . . . thanks to BIOS-modding.

rseiler Posted December 30, 2020 Share Posted December 30, 2020 I have an older Intel board that I wouldn't want to attempt to BIOS mod, and it's not a popular one, so I doubt anyone has done it for this model. It's also only only PCIe 2, so the speed would be hobbled. And I doubt Clover would get along well with weekly build upgrades. But what do you mean by most NVMEs not being able to be used as boot drives? Don't most systems these days come with exactly that kind of drive? Certainly laptops. I thought any current NVMe drive could be installed on a modern system (not to be confused with mine) and be used as a boot drive. Unless I completely misread you.

UberGeek Posted December 30, 2020 Share Posted December 30, 2020 My previous post makes neither any mention of modern PCs nor of laptops . . . it refers specifically to PCIe-mounted old PCs which existed before the advent of NVMe drives. FWIW, modern motherboards ship with a dedicated port (slot) for NVMe drives and laptops never ship with PCIe ports (slots.) 14 hours ago, UberGeek said: Just a heads up for those who might own a old system (PC) . . . 14 hours ago, UberGeek said: If the motherboard does not support NVMe though . . . 14 hours ago, UberGeek said: ps: The screenshot on my previous post was generated from a PCIe-mounted NVMe on a 9-year old PC . . .
