    Actually, it's not unusual for single women to have large dogs for protection. Even if the dog is a sweetheart, most people would be afraid to mess with the woman because of the size of the dog.

    Lady Fitzgerald got a reaction from tsjamm in UnRaid vs Raid   
    The purpose of RAIDs (other than RAID 0) and unRAID is to provide redundancy. Redundancy only protects against data loss due to drive failure (up to a point), which will allow a computer to continue to operate after a drive failure, but should NOT be considered a backup (in fact both RAID and unRAID need to be backed up to protect from causes of data loss not due to drive failure). RAID and unRAID have overhead, meaning the total usable drive capacity will be less than the combined capacity of all the drives. There a many levels of RAID but the most common in use for redundancy are RAID 1, 5, and 6 (RAID 0 is only for increasing speed and combining drives into a single volume). Nested RAIDs, such as 10, 50, and 60,  combine the advantages of more than one kind of RAID (usually RAID 0 and another RAID level) to make up for slower speeds and to improve drive failure tolerance (at a cost of higher drive overhead).
     
    RAID levels (other than 0) store data on multiple disks in stripes with the stripes distributed in such a way that, if one or more disks (the number depending on the level of RAID) should fail, all the data will still exist distributed across the remaining drives. The downside of RAIDs is, if more disks fail than the RAID is intended to allow, all the data will be lost. Also, drives need to be all the same size. If drives of various sizes are used, every drive will only use the capacity of the smallest drive. Adding drives to a RAID involve rebuilding the entire RAID
     
    UnRAID doesn't use striping. Instead of being scattered across stripes, data is written directly to the drives and one or two parity drives provide the redundancy. To over simplify the process, when using a single parity drive, the unRAID system will start by looking at the first bit of all the nonparity drives and add up the 0s and 1s. If the total is even, it will write a 0 in the first bit of the parity drive. If the total is odd, it will write a 1. Rinse and repeat until all bits of data have been accounted for. When a data drive fails, unRAID will start recovery on the replacement drive by again adding up the first bit of each drive, then compare it to the first bit of parity drive, then write either a 0 or a 1 to the replacement drive to make the total match the parity drive again. Again, rinse and repeat for the remaining bits of data.
     
    UnRAIDs that use two parity drives use a complex algorithm to accomplish the same thing as a system with one parity drive. The advantage of two parity drives is, if one parity drive should die, the unRAID will still be protected. Losing the pairity drive on a one pairity unRAID will not cause data loss but the data will be unprotected until the pairity drive can be replaced and rebuilt.
     
    The advantages of unRAID include being able to use drives of different sizes as long as the parity drive(s) is as large as or larger that the largest data drive. Since data is written directly to each drive instead of scattered across multiple drives, if more than the allowable number of drives fail, the remaining drives will still have the data written on them fully accessible, minimizing data loss. Unlike RAID, adding a drive does not require rebuilding the entire array.
     
    The main downside of unRAID is it's painfully slow, often too slow to keep up with the incoming data. One way to deal with that is to use SSDS for all the drives. That can be rather expensive. A less expensive way is to use a cache to temporarily hold incoming data until the unRAID catches up. While HDDs can be used for that, SSDs are usually a better choice. This works only where there are sufficent lulls in the incoming stream of data to allow the unRAID time to catch up.

    I have no idea. My Daddy worked from a quickie hand sketch when he built mine. I made a slightly fancier hand sketch for the one I built for my son (we didn't have the internet back in "them there" days). It was basically a bottomless box that mounted to the wall. The box "lid" (think Murphy bed) was hinged at the bottom and, when folded down, was supported on the free end by a leg on each side that swung down when the "lid" was down and swung back up against the wall when the "lid was back up on the wall. The layout itself was on a piece of "beaver board" (rigid soft cellulose wall board insulation; I think it's called sound insulation or deadening board now) recessed into the "lid" with spacers between it and the plywood of the "lid" to allow for wiring underneath and to deaden the sound of the trains.

    I also ordered an extra battery and PSU.
     
    This thing is a boat anchor and is built like a brick outhouse! The brick PSU is close to the size and weight of an actual brick (it runs cool, though). The screen is the best I've ever seen on a laptop.
     
    I had one heckuva time installing Linux Mint Cinnamon 19.3 due to the NVIDIA graphics card since Mint doesn't have preinstalled NVIDIA drivers so I had "fun" getting a display so I could install the drivers. System 76 left out a few details when I asked for help so I had to do a lot research on the interwebz and do a lot of trial and error (mostly the latter) before I finally figured out how to get it installed.
     
    It came with a 250GB Samsung 970 EVO with Ubuntu installed (my other choices were two versions of POP OS) but I yanked that an replaced it with a 512GB 970 Pro to install Linux on, keeping the EVO for a fall back drive it I wasn't able to get Mint installed. There is room for a second M.2 drive but I doubt I ever will.
     
    Installing the 4TB Samsung 860 Pro was a nightmare. The service manual had directions for installing an M.2 drive (like I needed any) but didn't have directions on how to install a 2.5" drive (mutter, mutter, mumble, mumble). The computer came with a bag of parts for installing the drives (there is room for two 2.5" drives but I doubt I'll ever install more than one). I was able to figure out the hold down bracket but the other two parts were a bit more of a mystery. I found out what one was for after calling System 76 (they don't make the computer; they sell a rebranded one they order built to their specs) but they were stumped by the other one. I finally found out searching on the "interwebz" (you gotta love Bushisms) where I found a video that showed an installed drive.
     
    One I first got it, I looked for over half an hour for the power switch. It's in a prominent location but, between the unusual shape and the lighting in the room (it's actually bright in here), I just couldn't see it. Now that I know where it is, it's not a problem and is easy to use.
     
    The battery is not particularly large since this such a powerful machine. At best, I'll probably get only 2 hours of life out of it, depending on what I'm doing with it so it will be more like a UPS when on the road (I may take the battery out at home and depend on an actual UPS I already have in the room). Due to its weight, it's not really intended to be carried around a lot. I normally had my notebooks connected to AC all the time so this isn't going to be a problem for me.
     
    The extra PSU will be handy for when I go out of town (not anytime soon, obviously; stupid Corona virus). I can keep one out of the way under or behind my desk for regular use and the other one can stay in the computer's bag. That way, I won't have to dig the PSU out from under and or behind my desk so I can take it with me when I hit the road. I got the extra battery so, if System 76 no longer sells them when the battery dies, I'll still have one.
     
    Despite the "fun" I had at first, I'm pretty sure I'm going to love this computer. Even though the keyboard is a chiclet keyboard, it's the best one I've ever used. The keys are backlit and has multiple colors plus brightness controls. The screen is one of the best I've ever seen, if not the best (there was also a 4k option but I didn't need that). It's got the power of a desktop and has plenty of room for storage expansion should I ever need it. If I ever need it, I can expand the RAM to 64GB.
     
    I'll be spending the next few days installing programs and transferring data to it before it becomes my daily driver. I still need to get a bag for it and replace my spare 4TB SSD I installed in the computer. I already have a couple of wireless mice I can use with it.

    Oh yeah, it's amazing what a boost in moral can come from learning that one has ADHD and what it's all about. Learning you are not lazy, stupid, or crazy is so liberating. In fact, their is an excellent book by that title, You Mean I'm Not Lazy, Stupid or Crazy?!: The Classic Self-Help Book for Adults with Attention Deficit Disorder, that is written in language lay people can understand. It's surprisingly accurate--dead on, actually--for have been written by non-professionals and is still relevant today despite being written so long ago.
     
    Sadly, there are a lot shrinks who are unfamiliar with adult ADHD and many people with it slip through the cracks.

    And where did you get your degree in Psychology? I felt he was spot on.
     
    For the record, I got mine from Abilene Christian College, class of '71. Even though I never used my degree vocationally, I did continue my studies informally, eventually concentrating on LGBT studies, including working with transgender support groups and, occasionally, speaking to college classes. After being diagnosed with ADHD, I expanded my studies to the area of ADHD.

    You can say that again! Imagine someone having to go through school and the work place not being diagnosed with ADHD until in they were in their early 50s. I don't have to imagine it because that was me. ADHD was not really known about in the '50s to the early '70s when I graduated from college.
     
    I have the same thing although it was never formally diagnosed. It never manifested itself until after I worked 5 1/2 years on third shift for a convenience store chain after retiring the first time. Prior to that, I had worked jobs all my life that required to get up early in the morning so I was able to bull my way through it. Now that I'm retired for keeps, I affectiuonately refer to my DSPD as shift lag since it is so similar to jet lag. The older I get, the harder it is for me to overcome it.
     
    Exactly. I had learn most of my coping mechanisms on my own by the time I was formally diagnosed.

    Lady Fitzgerald got a reaction from Vishera in external HDD,prone to failures?   
    In theory, yes. However, the drives inside most external drives are of lower quality than bare internal drives. Manufacturers "justify" this practice by saying the drives don't need to be a higher quality since they assume people will not be running them as much as drives inside a computer. Many, if not most, experts do not recommend "shucking" (the practive of removing the drives inside external drives). For the same reasons, I also do not.
     
    Adding to this is many manufacturers are now using SMR (Shingled Magnetic Recording) drives in their external drives. These drives are less expensive to make but, depending on how they are used, they can be painfully slow. They are fine for archival use where you write data to the drive once and never erase any of the data so you can replace it with more data. If you write over a sector that had been previously written to, the process will be painfully slow. 
     
     
    Not always. Sometimes, the drives inside an external drive enclosure connects directly to USB, not SATA.
     
     
    Again, I do not recommend it. I understand what it is like to be on a tight budget (I was there most of my life) but you have to keep in mind that you generally only get what you pay for. Buy something cheap and the quality will be cheap. In the long run, buying something cheap will probably be more expensive since it will have to be replaced more often.
