- 1Good question, tough "and SSD disks have very complicated garbage collection" I feel this is too abstract, can you lay out?tungsten– tungsten2019-09-22 17:45:29 +00:00Commented Sep 22, 2019 at 17:45

- also note, that despite urandom being slow, it is still faster than the majority of consumer hard disk drivesRichie Frame– Richie Frame2019-09-23 05:26:47 +00:00Commented Sep 23, 2019 at 5:26
- @RichieFrame I think that's outdated. Samsung 860 EVO is a popular consumer drive, and it gives 520MB/sec sequential writes. NVMe drives are not expensive and give ~1800MB/s sequential writes.Z.T.– Z.T.2019-09-23 05:34:08 +00:00Commented Sep 23, 2019 at 5:34
- @Z.T. hence why I said hard DISK drives, my 6-driveraid6 array pulls about 250MB/s, even though each individually does 160MB/s sequentially raw, which is typical for an enterprise grade 7200rpm SATA driveRichie Frame– Richie Frame2019-09-23 05:52:36 +00:00Commented Sep 23, 2019 at 5:52

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. web-application), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
