I'm at around 18 months. 100% capacity now. Knock wood, no issues.
I've been using the 5TB on 3 Bolts now for about 2 months without any issues on TE4.
So an update. My 5TB drive is still working after 18 months. However, I upgraded a friend's 5TB at the same time and his just died.
I also think I found out why some people's drives die fast and some last longer. Stand by mode.
So if your TiVo is always on and never goes into standby mode, TiVO live is always recording 6 tuners 24/7 into a 30minute cache. That obviously pulverizes the drive.
My TiVo always goes into standby mode when I turn the TV off (the harmony remote does this automatically).
Things still record in standby mode, it just doesnt do the live tv 24/7 recording thing and also doesnt record suggestions. See here: https://support.tivo.com/articles/Features_Use/Power-Saving-and-Standby-Modes
I am upgrading my TiVo to an SSD, see this thread if interested: 5TB Bolt Drive to 7.68TB SSD Upgrade, Best Approach?
This article on SSDs got me thinking about standby mode being the answer to why some of the 4/5TB 2.5" drives die and some dont, as you can see, it is a significant factor in lowering life expectancy of an SSD drive:
Using SSDs in DVRs - in Koherence
Vs "always recording"
So I think this "always recording" penalty also applies to spinning hard drives. In particular, 2.5" drives are not as robust as 3.5" enterprise level drives for such "always on" abuse.
is buffer usage worse than spinup/down on a non-ssd?
Not sure, but I suspect there will be low latency on an SSD. I think folks are right, that without TRIM you should expect 1/3 speed writes over time, but that is still faster than the 2.5" spinner, so it should be fine. Well at least in theory. Time will tell. Doing upgrade today! Fingers crossed!
Thanks guys. I tried the MFSTools 3.3. Made a USB thupmbstick, but my surfacebook wouldnt boot it, so I just gave up. I did install the SSD. MFS Formatter did it's job and it formatted the 7.68TB SSD out to over 7100MBs and resulted in well ever 1200 HD recording hours.
So now we'll see how long it lasts.
Initial notes. The boot time etc isn't any faster. Which makes sense as I have come to realize, the Bolt has some kind of mini SD card boot device somewhere on it. The OS boots from that. So the only "speed up" the Bolt will gain might be when it's trying to get a listing of shows while it's heavily being written to. So I suspect in general, it should seem like the same speed.
The one benefit I did instantly feel was the lack of anxiety of moving the bolt around while it's working. Without a real spinning drive moving the bolt around is now anxiety free, no fear of a drive crash.
Anyway, let's see how long this puppy lasts.
Any issues yet? I've been running my 5TB Seagate SMR drive for 5 months but woke up to 4 flashing lights this Monday. Unplugged it and plugged it back in and it seemed to boot properly, but I'm not sure if the drive is on it's way out or not.
Don't newer SSDs have hardware TRIM built in though? Previously I believe it was up to the OS to handle it. To what you were saying above about power saving options (wasn't going to quote that whole message) is that I believe there is a few different levels of power saving options and I had to set mine to low otherwise it would miss some recordings. Don't know how much this option really saves the drive from spinning though. Contemplated grabbing a 4TB Micron earlier in the summer for $300 (they were on sale for about $350 and eventually dropped to about $300 - thread was here). Grabbed myself 2 x 1TB Micron drives for a couple of PCs from that deal and have been happy with them. Anyway if you look at the post above I had 4 flashing lights on my Bolt (5tb Seagate SMR drive) the other day. Rebooted it and it seems fine, but now I'm a little worried. Not seeing any deals right now on any larger SSDs and not looking to spend a ton on it either so may be thinking about just grabbing the next deal I see on a 2tb one and getting one with a decent warranty such as 5 years (if your projected #s are correct above, I'll probably use it). I like having the extended size (hell I'm at 80% with the 5tb, but I'm sure a lot of it can be cleaned up). Maybe I'll consider a larger 3.5" drive but not really keen on the idea of an external enclosure. Maybe I'll figure out a way to mount it internally (move some things around like the fan) but then I would still need to find 12 volts for it. I may even think about throwing the guts from the Bolt into a little itx case or something. Who knows. Just ranting or whatever. Let me know how that SSD is doing though.
So I'm no longer using the 5TB Seagate spinner. I was not experiencing problems but my friend was after about a year. The difference was he did not put his TiVo in any power saver mode. I regularly put my TiVo to sleep because that's what the harmony remote does. That said, I think if you just turn on even the lowest level of power saving (so it still records all your shows and records recommendations, but does NOT record all 6 tunes 24/7 in live cache) it will last for at least 2 or 3 years.
I'm currently doing this with an SSD and Im at around 6 months of use, so we'll see if my theory holds.
4 lights on one of 2 5TB-upgraded units this past Saturday night, all good after reboot. Between the two units, maybe 5-6 instances between the two since late summer 2018. I'll have to be more diligent in keeping records, but incidents are rare and minor. I do not power-save, do not record suggestions, and both are on TE3.
I purchased 3x 5TB drives from Costco as regular USB drives in December 2018 and one was DOA, so definitely test thoroughly before using.
Incidentally, the shucked drives are on the certified list for the Synology ds620 slim NAS as they are the only 5TB 2.5" drives in the market. Unfortunately, used units are not available and Synology NASs are rarely discounted.
