  • This is highly dependent on what your needs are and how you plan to solve it. SATA-3 maxes at 6gbit, which SAS-2 had in 2009. Most cards are x8, and have at least 4 full speed SAS lanes (of whatever generation). That means 24 Gbit. PCIe x8 2.0 (from 2007) had 4 GB (32 Gbit). So if that meets your needs, you can run it on an ancient board.

    However, if you need something more advanced, such as SAS-3, a SAS expander, or a card with more native lanes, then you would need to plan accordingly.

    I’ve been running on an LSI 9211-4i4e, which is only a PCIe 2.0 card, for many years. I did notice my speeds dropped when I expanded the 4e to a 15-bay DAS (plus the 4 internal SATA drives), but it’s still enough to meet my needs.


  • It’s not really about 24/7, but it is about quality of components. Enterprise gear is made using slightly better parts and tighter tolerances. Things like more expensive capacitors rated for more hours/cycles, better power filters, things like that.

    The end result (and this is easily verified) is the failure rate is much, much lower than comparable consumer-grade equipment.

    There is sometimes a blurry line between what counts as enterprise vs pro-sumer vs consumer gear, though.





  • There is a ratio, which may be a new experience if you’ve only used public trackers. It’s not really a big deal if you have some patience, though.

    TL (as do most ratio trackers) gives you bonus points for your time seeding, even if you have done nothing more than make it available. You don’t have to upload even a single byte unless someone wants it, and you’ll still get points. These points can be used to buy upload credit.

    If you simply keep seeding everything you download, and buy credits as needed, you’ll quickly have more ratio than you could ever hope to burn. No need to spend money or anything.

    As for limited content, it’s a general tracker. You probably have niche interests, so you would be better suited on a more specific tracker. I’ve almost never had issues finding anything mainstream, although quality can be a crapshoot. That’s the main reason I usually use other trackers.


  • It’s not entirely true that you can’t identify him from that Facebook account. It’s just really, really hard.

    Facebook almost certainly knows who he is. Like specifically, name and all. Their data mining is VERY extensive, and he likely has other accounts.

    Anyway, with a lawyer’s help, you can (possibly) get a court order for Facebook to reveal what they have on the guy. They certainly have things like IP addresses and timestamps, but they also probably have name, other associated accounts, viewing history across the web (from those “share with Facebook” icons/links, even if untouched), and hundreds or thousands of additional pages.

    Is it worthwhile? Probably not. But it can be done.




  • During US prohibition, there were “grape bricks” with warnings not to dissolve in water and place in a cupboard for 20 days, because then it would turn into wine.

    A simple negation probably won’t cut it legally (the bricks had a significant legal purpose), but you could probably word it in a similar way. For instance, “While VPNs are effective at anonymizing yourself during piracy, they can also protect your privacy from data mining ad companies”.

    At some point, you’ll have to conspicuously avoid the topic and let people infer. Remember when high-speed connections were advertised as being great to “download movie trailers”?

    I left them years ago, but their VPN software has (had?) a critical bug - the killswitch treats “connecting” the same as “connected”.

    Meaning that if the connection drops for any reason and is not immediately reestablished, you not only lose all protection, but you have a false sense of security.



  • Kind of. They will be multiples of 4. Let’s say you got a gigantic 8i8e card, albeit unlikely. That would (probably) have 2 internal and 2 external SAS connectors. Your standard breakout cables will split each one into 4 SATA cables (up to 16 SATA ports if you used all 4 SAS ports and breakout cables), each running at full (SAS) speed.

    But what if you were running an enterprise file server with a hundred drives, as many of these once were? You can’t cram dozens of these cards into a server, there aren’t enough PCIe slots/lanes. Well, there are SAS expansion cards, which basically act as a splitter. They will share those 4 lanes, potentially creating a bottleneck. But this is where SAS and SATA speeds differ- these are SAS lanes, which are (probably) double what SATA can do. So with expanders, you could attach 8 SATA drives to every 4 SAS lanes and still run at full speed. And if you need capacity more than speed, expanders allow you to split those 4 lanes to 24 drives. These are typically built into the drive backplane/DAS.

    As for the fan, just about anything will do. The chip/heatsink gets hot, but is limited to the ~75 watts provided by the PCIe bus. I just have an old 80 or 90mm fan pointing at it.
