TerryO Posted June 18, 2017 Posted June 18, 2017 (edited) I have been considering backing up our CD collection on to a external hard drive and wondered how many hours of uncompressed music would a 1 TB hard drive store when I came across a website with this info on it. My question is, is this information correct? I have several external Seagate hard drives, up to 4 TB each, that we no longer use at work so thought I might use one or more of them. cheers Terry Edited June 18, 2017 by TerryO
powerav Posted June 18, 2017 Posted June 18, 2017 That's a how long is a piece of string question, all depends how they are ripped and what format, FLAC, WAV, HiRes 24 bit 96 or 192. I have 1075 albums at 618G but they are a mixture of FLAC 16/44.4 at the lowest and up to 24/192 at the highest. 3
Janjuggler Posted June 18, 2017 Posted June 18, 2017 (edited) Hi I have been slowly ripping my CD's to 16 / 48 a mix of flac and wav files and looking at what I have done since the beginning of May 2017, 621 CD's take up a little under 300GB, but that also depends on the length of each song and how many songs are on an album. A better example can be found below for 5 minutes of stereo of differing formats: Format Sampling frequency Quantification Size DSF 5.6 MHz 2.8 MHz 1 bits 1 bits 403 MB 201 MB DSDIFF 5.6 MHz 2.8 MHz 1 bits 1 bits 403 MB 201 MB WAV 192 kHz 96 kHz 88.2 kHz 48 kHz 44.1 kHz 44.1 kHz 24 bits 24 bits 24 bits 24 bits 24 bits 16 bits 329 MB 164 MB 151 MB 82.4 MB 75.7 MB 50.4 MB FLAC note: Sizes of FLAC files can vary greatly depending on music dynamics, conversion tool used, what format the file was converted from and Level of compression used. The information here is general and currently being revised for more accuracy. 192 kHz 176.4 kHz 96 kHz 88.2 kHz 48 kHz 44.1 kHz 44.1 kHz 24 bits 24 bits 24 bits 24 bits 24 bits 24 bits 16 bits 195 MB 170 MB 61.3 MB 56.3 MB 30.8 MB 27.9 MB 6.69 MB MP3 44.1 kHz 44.1 kHz 44.1 kHz 44.1 kHz 44.1 kHz 320 kbps 256 kbps 192 kbps 128 kbps 92 kbps 11.4 MB 9.15 MB 6.86 MB 4.57 MB 3.43 MB Thanks to DSD-Guide.com Hope this helps JJ Edited June 18, 2017 by Janjuc 5
PleasantSounds Posted June 18, 2017 Posted June 18, 2017 If you rip your redbook CDs to FLAC with maximum compression, most should take below 300 MB per disk. That gives you about 3,500 CDs per 1 TB hard disk. Looks like the 17,000 hours estimation is based on something like 128 kbps MP3. 1
ophool Posted June 18, 2017 Posted June 18, 2017 Terry, using a slightly conservative NTFS disc usage of 10.5 MB per minute of LPCM/Wav @ 16/44 (Redbook CD) my calculations give app 1600 Hrs per TB so no the figures quoted are not correct (or I messed up ) For a more practical measure, a folder in my music library that is all 16/44 .wav and contains 168 CDs takes up 100 GB almost exactly. 1
TerryO Posted June 18, 2017 Author Posted June 18, 2017 Another question if you guys don't mind please. What is the best format to store music in that doesn't down grade sq when played? Good quality hard drives are pretty cheap now so Im not wanting to squeeze everything onto one hard drive at the expense of sq. cheers Terry
betocool Posted June 18, 2017 Posted June 18, 2017 @TerryO, whatever format, have a backup. Mirror the main drive and update the secondary whenever you put something new into the first one. 4

Mirror the main drive and update the secondary whenever you put something new into the first one. I have to agree. A NAS with a Raid 1 configuration will give you piece of mind. NAS units are getting cheaper too as are hard drives. I have 2 2tB drives in my NAS. I also have everything on an external drive too. Belts and braces. Then I keep really crucial stuff on Dropbox and Google Drive (tax stuff etc). Belts and braces and braces. Edited June 18, 2017 by scumbag

ophool Posted June 18, 2017 Posted June 18, 2017 I stick with WAV, 100% lossless +1 dbpoweramp cd ripper & tag & rename can handle/create/modify metadata and store track info and album art in .wav files and foobar can read it so nothing is lost there either. 3

Guest scumbag Posted June 18, 2017 Posted June 18, 2017 5 minutes ago, Kaynin said: I stick with WAV, 100% lossless. WAV versus FLAC is one of those intractable audiophile debates. FLAC's are lossless but some argue that the act of inflating them is audible. As servers gain more power and RAM I can' only see any differences (if there are any) fading into obscurity.
GregWormald Posted June 18, 2017 Posted June 18, 2017 I have 3000 albums in 1TB of storage--all ALAC (about same size as FLAC files). Greg 1
PleasantSounds Posted June 18, 2017 Posted June 18, 2017 1 hour ago, powerav said: Flac level 5 The only advantage of L5 over higher compression levels is the compression speed. There's not even discernible difference in decompression speed, and the final result is bit for bit identical. Given the choice, I would always go for L8 and let the computer sweat a couple of seconds longer, resulting in a slightly smaller file size. 1
LogicprObe Posted June 18, 2017 Posted June 18, 2017 I just got an 8TB archive drive the other day. My music files are around 1TB and mirrored...............but I thought another copy wouldn't hurt! All wav...........so they are easily edited. 2
GhostCoast Posted June 19, 2017 Posted June 19, 2017 most people cannot tell the quality difference above 192 kbps mp3. so yea theoretically higher the better 320 is great flac is better but you can't really hear it.. if someone claims , i'd invite them to a A B test and see how many times they can nail it blind folded

Regardless of whether you can hear it under stringent DBT, once you've thrown away all that psycho-acoustic data, it's gone. On a practical level, you have no opportunity to change the file format without destroying it further. FLAC offers a reasonably sized file with no loss of data. And storage is cheap and obeys Moores Law so it's getting cheaper. Why would you eternally compromise your music collection for no good reason? Edited June 19, 2017 by scumbag

Experience is king.
GhostCoast Posted June 20, 2017 Posted June 20, 2017 wow.. there is nothing wrong with flac or chasing higher bitrates.. it's cool if you have the resource and the space.. i' am basically saying 192 is good enough and "most" people can't hear the difference above it (fact) i have abundance of songs at various qualities from average to ultimate.. and extensive listening experience with variety of high to very high quality devices i've seen many cases of flacs or 320kbps mp3's circulating around which are all were simply converted from youtube downloads that is 128kbps.. there are lots of pink balloons flying out there and people talk... i watch people listen to digital from their mobile phones or portable whatever devices via awful distorted tiny speakers and talk of bitrate quality... well... i don't intend to start a long debate on this , many things in hifi planet is subjective, and dependent on combinations of factors... some people claim they can see the magical celestial beings start flying around the room at ultimate bitrate qualities.. his mind, his facts.. neither he can prove it's true, nor i can that it isn't .
Happy Posted June 20, 2017 Posted June 20, 2017 @GhostCoast while I don't necessarily disagree with your view per se, your intended audience here isn't really 'most people'. The mob here is a bunch of audio nuts

Sort of hard to tell whether that was meant as a barb or tongue in check. This is where emoticons are useful. I don't consider 192khz, which I think most commercial FLAC's top out at, to be all that high. Not in the context of DSD and DXD. I personally rip FLAC's at the native bitrate that is on the CD for example. There's no point in wasting disc space to up-sample an original that was captured at a given bitrate and sampling rate. My whiz-bang direct stream junior DAC takes care of up-sampling to DSD rates for me and that's when the magical celestial being start to appear.......
