• Everything I Know About SSDs (2019)

  >if you get the SMART data with smartmontools/smartctl, you can inspect Percentage Used. CrystalDiskInfo[1] can be used for this purpose over on Windows. Some vendor-provided utilities like Samsung Magician will also provide this data with appropriate drives.

• A3Launcher has broken my steam, more info below. Anyone know how to fix this chicanery?

  Verify that CrystalDiskInfo shows "Health: Good" for drive D. Source: 5 months ago

• Failed Hard Drive From Windows System

  Plug it directly into sata and see if it's shown in disk manager with the correct capacity. If it is post a screenshot of the smart data from https://crystalmark.info/en/software/crystaldiskinfo/ and we can see what the best way to proceed would be . Source: 5 months ago

• Can’t access old HDD

  The disk is likely failing. DO NOT attempt any write operations like assigning a letter or changing file ownership. What you're saying suggests that the filesystem is corrupted, it's just unclear to what extent. It would be helpful if you provided a screenshot from CrystalDiskInfo. Most likely the best course of action is to boot https://www.hddsuperclone.com/hddlivecd and image the drive to a file on a different,... Source: 6 months ago

• My SSD suddenly died. I only lost 10 minutes of data, thanks to ZFS

  Minimum write size of a modern Flash chip can be ~100MB(!) according to a comment found in a random orange website[1]. So 5MB write every 10 minutes can be 600MB/hr, which is 4.8TB/8-hr-day, which is 24TB/40-hour-week, which is 3.43 DWPD real time for a 1TB drive, and 2500 TBW in 2 years real time[2]. Official quoted specification for SN850 is 600 TBW of write endurance, likely after derating for obvious warranty... - Source: Hacker News / 8 months ago

• Dire SMB speed with on PC to NAS

  Assuming two systems use flash storage, network bandwidth is identical and it is configured the same way, there should be an issue within the PC, either system or storage drive. Check the system logs for errors and warning events related to data transfer from/to NAS. Try to benchmark the PCs' disks using fio to confirm they have similar performance. https://github.com/axboe/fio. Source: 10 months ago

• Ask HN: What are some good resources for learning about low level disk/file IO?

  Not specifically addressing your question, but when you get to the point of wanting to start doing some experiments you may find that 'fio' [1] is very handy. [1] https://github.com/axboe/fio. - Source: Hacker News / 11 months ago

• KVM virtual machines on ZFS benchmarks

  The dd is not a good benchmarking tool, you should use something like fio and probably tune it to use the ioengine most similar to your use case (eg. a database server will probably use some async IO interface). In your first example (with bs=1G) probably something (the guest OS, the qemu/kvm or the host OS) have split into smaller chunks anyway. Source: about 1 year ago

• SSD Sequential Write Slowdowns

  All linux tests are run with fio 3.32 (github) with future commit 03900b0bf8af625bb43b10f0627b3c5947c3ff79 manually applied. Source: about 1 year ago

• Just write the f*****g parser.

  Agree, I used flex/yacc to add an arithmetic expression evaluator to fio a few years back to allow simple math with some units in fio's job files, and for stuff like that, they're fine, but I wouldn't want to use them for a real language, the error handling is kind of a nightmare.
