Writing 10gb per day for a year to a "512GB Ultra Fit" would only use each cell around 7 times. Thumbsuck a worst case scenario with QLC having 250 write cycles and you're looking at 34 years of writes. | |

| Jan 2, 2018 at 22:21 | comment | added | Mark | @MrChips, if you're writing the data from Linux, you can use a flash-oriented filesystem such as F2FS to handle the wear-leveling for you. | |

| Dec 21, 2017 at 3:41 | comment | added | MrChips | Update: Haven't found anything yet that fits all the criteria, but I have located a small USB-to-mSata adapter that would allow me to use a proper mSata SSD (that has write-leveling and SLC chips for write-longevity). The only problem is that it is bigger than I would have preferred, and draws significantly more current than a similarly sized USB stick. On the other hand, I also found several companies that make SLC-based USB sticks (not just Cactus-Tech), but those don't have write-leveling. The search continues... | |
| Dec 12, 2017 at 23:31 | comment | added | MrChips | So I'm not calling this an answer yet, but I found this company: cactus-tech.com that sells industrial-grade SLC storage devices. No write-leveling on the USB drives though. That seems to be non-existent. Also, they are wholesale in bulk only. No retail. Continuing my search... | |
| Dec 12, 2017 at 20:44 | comment | added | MrChips | @SEJPM - Thanks for that info, I will definitely look into them. If I get anywhere with it I will let you know. | |
| Dec 12, 2017 at 18:18 | comment | added | SEJPM | Additionally there seemes to be a taiwanese / russian company Mach-Extreme Technologies offering their "Ultra" line of sticks which also feature SLC chips. | |
| Dec 12, 2017 at 18:14 | comment | added | SEJPM | While not a real answer, I have found a german company called Winkom who have put SLC chips into their (USB3.0) sticks. Sadly their webpage is available only in German, but I'm sure they'd also be happy to tell you more about their sticks and to sell to your location. | |
| Dec 12, 2017 at 17:04 | comment | added | MrChips | @CFinley - Agreed. It would be perfect! ...except it is physically too big, and my core board does not have SATA circuitry, just USB. But you did help me here: I have updated my question to show that yes, SSD technology is what I would like, but in a small USB-thumbdrive package. Thanks! | |
