    i sure will. curiosity is getting the best of me. i may check it in a week. by then all my season passes will record and i can still get a general idea of how much is being written.

    after a typical week of tv watching and recording I pulled the drive to check the data. on the average day, my tv goes from 5am to 1030 pm by either the dvr or all 3 boxes at the same time. I recorded 7 shows this week also. the rest was live buffering/paused tv/double play.

    divided up the data written by day and there were 288GB per day written to the 1TB samsung evo. going by that, if every week was used as heavily as this past week, which it wont always be, my ssd should last me 5.7 years before reaching the total tbw threshold.

    if any of you are considering using an ssd in your owned genie dvr's be sure to get one with the highest TBW rating you can afford. ssd's are not as expensive as they were a few years ago and the performance difference is, in my opinion, worth the upgrade. the 860 evo I'm using has a 600 TBW rating. reports show it can go well past that mark. ill keep using it until it dies. chances are it will outlive my hr54.

    you are probably right about that one ;)

    while I had the ssd pulled I decided to do a quick experiment with another hdd I have.

    brand new wd blue 5400rpm 2tb with 256mb cache vs. my 1tb evo ssd.

    wanted to do a boot test to see which drive went from red button to live tv the fastest. here is what I found.

    the 5400rpm took 3:27.52 from red button to live tv.
    the ssd took 3:52.65 from red button to live tv.

    its not that much of a difference but I was shocked to say the least. never seen that one coming. however the ssd provides extremely faster menu responses. nearly instantaneous. smooth as silk guide scrolling & everything else. I did the test twice and got similar results. +/- few seconds.

    because the ssd is much faster once booted it does make an excellent upgrade.

    perhaps you saw just time variation in "a carousel" - the method of obtaining APG data from sat stream;
    other point is - the external storage [HDD/SSD] using by DTV OS/Linux to keep/update many DBs, I would recommend you mount the drive under Linux and look by yourself - how many DBs there, how big its size, etc; from message log files you'll see time stamps and get a knowledge what/when OS components running

    Has anyone tried a WD Purple drive in an HR? I know they're optimized for multi-camera surveillance DVRs, but I've read a few reports elsewhere of folks presuming they'd be fine for other-than-DTV 2-stream cable/sat DVRs and have been happy with their performance...

    I ask as the 2TB WD Green I've been using (in a seemingly-bulletproof Thermaltake dock) with my trusty old (also seemingly-bulletproof) HR20 is on borrowed time: it appears to work perfectly (if a bit slow at times) but I'm sure it's over 10 years old now! :eek:

    I’ve never done Purple, only 2TB Greens for a long time and then a couple of Blues.

    Seriously though, I’ll never do a magnetic again, especially in a HR2x series. I just went with another 1TB WD Blue SSD last week from BB for a little over 90 bucks. They have that sale a couple times a month and works perfectly in my TT dock.

    Thanks!

    My dilemma is replacing a 2TB magnetic drive... copying isn't an issue... although it's been a decade or so since I've needed to do it... but 2TB SSDs with decent MTBF and TBW (i.e. Samsungs!) are still rather dear in price... :(

    I always tried to keep my HDDs at no more than half full. Any more than that on a two-tuner HR, and you have problems. Use an SSD, and you can fill that sucker up with no problems. I've filled up 500GB SSDs and had no problems at all. Simply put, you should be able to fill a 1TB SSD to its limit without problems. Do that consistently with a 2TB HDD, and you're gonna have problems.

    Rich, thanks for the comments.

    As mentioned, my concern is that the WD Green is long in the tooth, and I'd like to copy it to a replacement before it inevitably gives up the ghost! There's material on it that isn't available from other sources... believe me, I've looked! In the days before multiple streaming services became as common as they are today, I had a lot of movies stored, along with TV episodes. I've since deleted (most of) the movies and some of the TV, and the HR20 is mostly used for a few weeks of various series that I'm behind on watching.

    I try to keep the drive below 75% full... currently ~ 70%. When it was newer, below 80% was all that was needed to keep things snappy... other than occasionally slow guide scrolling. Nowadays, it sometimes has an issue with strobing (or dropping frames in a pattern) on OTA broadcasts, which are my big reason for keeping the HR20. :D It seems to happen more often the more full the drive is, but flushing the buffer (switching to SD channels seems to do the best job...) usually clears it... I'm not sure if the receiver is trying to write to a flaky sector or three, or...

    My next project is re-reviewing the two copy/replace drive megathreads for current best practices: best versions of GParted to use, etc.! :cool:

    Just keep the 2TB HDD inside the HR20, and utilize a new SSD in your dock for daily use- I’ve been doing this for years.

    When you want to watch something on the old drive, just shutoff the TT and reboot- which takes you to the internal. When your done, turn on the TT and reboot, and the DVR will switch back to the external. I’ve been doing this for years.

    Thanks... but the 2TB drive is already in the external dock, as mentioned in my first post above. ;) After all, the HR20 is the one HR2x that's the biggest pain for replacing internal drives... I've never even thought of trying to open it. My other trusty old HR, the HR23, is so easy you can open and swap drives with your eyes closed... in your sleep... nearly... :p

    Needless to say, I could swap back and forth between the old and new drive, but one thing that's less than bulletproof about the Thermaltake docks are their power switches... I'm already tempting fate! :cool:

    I hear you, but was just providing options. The 20 is a little tricky, but once you do it you’re done. The warranty is up on those and DirecTV is not taking them back.

    I’ve been one of the lucky ones to not have a TT failure with power switch. The alternative to that is to turn on/off using the power supply plug.

    I stopped using the switch years ago after a couple of switch failures. All the TT docks are gone and replaced with smaller docks for the SSDs.

    Which model of the 20s do you have? I've had a bunch of 20-100s, not one of them worked. I never had a problem changing HDDs in the 20-700s. I had twelve of them active at one time, each one had an internal 2TB drive.

    RICH is the SSD Test pilot and I've followed his advice and it works above and beyond my expectations :)

    Thanks. After I read your earlier reply a third time (after I'd replied, naturally!) I did finally get what you were getting at... my bad... :oops:

    Thanks. It's been a while since I've read through the entirety of this thread... which docks are you using now?

    I will re-read this thread, of course!

    It is a -700. I just remember reading the initial posts in the first copy/replace megathread and quickly decided a dock was the way to go! :D
