Hi All
Has anyone used a SSD either internal or external in a DTV dvr? If so , what was the results.

I dont know of any, but would have limited benefit. Speed wouldn't be one, noise would be the biggest. Also less recording space and while not an issue in a normal system, constant writes in a DVR function could be a problem. No support for TRIM etc.

There really aren't any SSD drives, affordable ones anyways, that are big enough to use on a DVR.

It's not worth it, SSD provides zero benefit vs. a HDD on a DVR system.

However SSD on a computer is friggn awesome, I have a boot time of about 15 - 20 seconds from BIOS.

It sounds like a HUGE waste of money. The prices of SSDs have come down but for a 1TB drive that's got to be over $500.

SSDs in desktops and laptops are great, I have an SSD in every computer now but your recordings will play exactly the same off an SDD as they would off an HDD.

Hi All
So cost is the main issue. I have read that a SSD has a limited number of READ/WRITES but this number could be so huge that it does not matter.
For reliability , noise and heat, a SSD should win hands down. Cost will soon be a moot point.

There are a lot of them out there but they're danged expensive. From what I've seen they're more than a buck a GB. 500GB SSD drives seem to be going for $600-$800 or even more. It would be very cool though.

I remember helping a friend put in a 5MB hard drive in an XT in the early 80s (I didn't know squat about computers then, it was my first into to the inside of a PC). The dang thing cost him over $1000. :eek2:

I'm sure the prices will come down quickly and we'll see affordable SSD drives (solid state drive drives, :scratchin :lol

I'm not sure the write endurance is quite up to par for DVR use yet...but it'll come.

I think the 1TB+ drives are in the thousands of dollars range. AAMOF, there is a 1TB SSD Victorinox Swiss Army Knife for about three grand.

The number is pretty huge and doesn't matter much for a computer, but a DVR is constantly writing even when not in use. Lack of support for some SSD functions makes it worse.

Has anyone tried to calculate the avg life of an SSD if used in a DVR...1 year, 2 years?

When regular HDD prices return to pre-flood prices...2TB go for $100...500GB SSD's are $500....still no contest for me, especially when I don't know how the technology will hold up when used in a constant writing environment.

 

[P Smith]

I recall it was calculated for a few years... check old threads where we discussed use SSD for DVR.
From the numbers, counting high cost and NO BENEFITS for DVR operating system, the academic question is no more then that.

Yet we keep getting semi-frequent recurring posts about the same thing...and the same conclusion.:lol:

Who would expect different ? Only each new 'inventor' here, who don't bother to search, read, learn ...

Just noticed the overstatement ...

The number is 5000 rewrites/erases; some low prices SSD has it as 3,000.

 

[dpeters11]

Unless they are not truthful (and I've always found this manufacturer to be good), I can get a 64gb SSD for under $100 that has a write endurance of 20gb per day for 5 years. Or for $130, double the capacity and 40gb per day for 5 years. To me, that is quite high on a normal system. Most people don't write that much, day in and day out. And after 5+ years, it isn't unheard of for a physical drive to fail.

Even if it was 3000 writes, that's a bit incomplete. It makes it sound like thats for the whole drive.

 

[Davenlr]

64GB drive, 20gb per day, means one rewrite every 3 days. What if the drive is almost full and the device is writing to the same 2 gb over and over several times a day?

 

[dpeters11]

I don't believe the algorithms work this way.

 

[P Smith]

You can revolve around GBs/days/times/etc whole day - the fact is: max 5000 rewrites/erases per sector (usually 2KB size). It's by Kingston who use Toshiba NAND chips.
Also I recommend you get a count of reserved space to understand better these numbers like 1000000 hrs MTBF, GB etc what normal user can read from glossy box.

What about the SSD Hybrid Drives? Any benefit?
