  1. The only thing I ever use RMA replacements for is as an offline backup disk => as already noted, they tend to be refurbished disks [and while I'm not quite as skeptical as Brian (bjp999) as to the process, I DO think these are not as reliable as new drives => I think they DO replace platter assemblies in a cleanroom if these show errors. And FWIW your drive does NOT have "a few reallocated sectors" => it has over 3,000 of them !! A few are fine; but when the number is that large, I'd absolutely not use the drive for anything except an effectively static backup drive.
  2. ... I suppose the answer to the question ["Are mechanical disks going to fade away?"], however, is, from a consumer's perspective, Yes. I think virtually all laptops and a very high percentage of desktops will ship with SSDs within a couple of years. But for applications with large TB capacities -- data centers, major corporations, etc. -- spinners will still be around for a good while -- at least until (as noted above) the cost/TB becomes much more competitive. Many of us would easily pay double the cost/TB for SSDs, but most won't pay ten times the cost. And even double the cost would require a bit of thought if the sole purpose was archival storage that's rarely accessed; or a media server that only needed enough speed to stream a movie or two.
  3. Certainly agree => spinners are going to be the choice for serious storage; but SSDs will rule desktops and storage where cost doesn't matter. But I doubt folks on this forum will be building 100TB arrays using SSDs anytime soon
  4. Remember that New Config means a NEW configuration. If all you're doing is replacing a drive, you're not changing the configuration --- you're just replacing a defective drive or upgrading an existing drive to a larger one ... these are normal functions for UnRAID and it will simply rebuild the drive's contents onto the new drive. Likewise, if you simply change the format of a drive, UnRAID will just format it with the new file system (IMPORTANT to realize that this will DELETE all of the previous content on that drive). It's only if you're actually CHANGING the configuration -- i.e. removing a drive; replacing a drive with a SMALLER drive (NOT a normal UnRAID function); or changing the slots you have drives assigned to; that you need to use the New Config option.
  5. Clock speed isn't the only thing to consider -- different CPU architectures can have very different performances relative to the clock speed. e.g. consider a 4GHz Pentium IV vs. any modern CPU at a much lower clock rate. I'd look at the overall performance as measured by a good benchmark ... and PassMark is by far the best one I've found. The E5-2683 has a PassMark rating of 17596 => well above any of the Ryzen scores. The Ryzen CPUs will have slightly better single core scores, but the Xeon has more overall "horsepower". Which is better very much depends on how you're going to use it ... but both are "good enough" that you aren't likely to notice a lot of difference.
  6. True that adding the 2nd parity first and then upgrading the initial parity always leaves the array protected => but in effect the same thing is true if you simply do a New Config with two new parity disks PROVIDING you don't use the array at all (or more precisely don't write to it) during the parity sync ... since if anything was to go wrong during that process you can still do a New Config with the original parity disk and check the "Parity is already valid" box.
  7. Actually Bob's idea is even better => just do a parity check to confirm all is okay; then do a New Config with BOTH of your 4TB drives assigned as parity 1 & 2 and let it do a parity sync; then do a parity check to confirm all was well ... and you're done . If anything goes awry, you can do what I originally suggested -- just do another New Config with the original 2TB parity disk and the "Parity is already valid" box checked.
  8. I'd do it like this: (a) Do a parity check to confirm all is well before you start (this should always be the first step in making changes) (b) Replace the 2TB drive with a 4TB drive -- do NOT use the array while the rebuild is being done ... if anything was to go awry, you could always replace the 2TB parity drive and do a New Config with "Parity is already valid" and be back to where you started. (c) Do a parity check when it's done to confirm the rebuild went perfectly. (d) Add the 2nd parity drive. (e) Do yet-another parity check to confirm the parity sync for the 2nd drive also went well. The extra parity checks (steps c & e) are optional, but I always confirm the results anytime I do a parity sync or a drive rebuild.
  9. (Didn't know if you were comparing it to an Intel i5 or i7 or an AMD A6)
  10. Which "I6" were you running? I'm not at all familiar with those CPUs
  11. Very good price -- a 35% bump for $100 is certainly an excellent deal The pricing for these older E5 Xeons is amazing -- the same is true for the registered RAM modules. You can build dual Xeon systems with 64GB or more for just a few hundred $$ these days. Very tempting !!
  12. Definitely a nice bump => from a PassMark of 4875 to 6559 ... a 35% increase in your "horsepower"
  13. I very seriously doubt this has anything to do with the disk format.
  14. Agree -- any modern disk is easily fast enough that an active movie stream at the same time as a write is NOT going to cause any issues with the stream. As Squid noted, you can easily see this by streaming a movie during a parity check. In fact, just stream a movie from a disk you're writing to in normal read/modify/write mode -- which has twice as many disk I/O's as turbo write, so would be even more likely to cause an issue ... and even that almost certainly won't cause any problems.
  15. Agree -- the upgrade has been out for over 3 weeks and clearly a LOT of folks have upgraded with no issue. A handful of folks who have seen issues with their systems that may or may not have any relationship with the actual version is hardly evidence that there's a fundamental problem with the latest version. In the few times that a release HAS had a significant issue it was very clear within a day from the feedback on the forum, and a fix was issued VERY quickly. After 3 weeks it's safe to say this release doesn't have any such problems.
