hp Posted December 31, 2004 Report Share Posted December 31, 2004 Hi All. I'm the proud owner of a new NH700. Cant belive the the quality and capacity at HI-LP. However i'm very dissappointed with the speed of copying CD's, its almost no better than real time. My system meets all the system requirements but i'm not achieving the quited 100x copy speed. Is there anything ican do to improve this? I'm running XPhome, 196 RAM, AMDK6 processor. Thanks HP Quote Link to comment Share on other sites More sharing options...
ROMBUSTERS Posted December 31, 2004 Report Share Posted December 31, 2004 The MD (not CD) copy speed which is quoted at 100x is in reference to the speed at which the HiMD recorders (the 700 included) can transfer data to the disc (somewhere around 400-800kb/s) The reason you are not coming close is because you are encoding the files into atrac3+ on the fly which means you have to wait for it to encode the file *before* it even starts the 100x transfer. To fix this problem rip your music into SonicStage and convert them in there. Then transfer the converted files to the MD. This will go at the higher speed. By the way, 100x only refers to transfering a 48kbps song not anything else, so in actuality it will be slightly slower. Quote Link to comment Share on other sites More sharing options...
Latexxx Posted December 31, 2004 Report Share Posted December 31, 2004 Your problem is the k6 processor. Quote Link to comment Share on other sites More sharing options...
Christopher Posted December 31, 2004 Report Share Posted December 31, 2004 Welcome hp. Yes, I'm going to have to agree with Latexxx on this one. Quote Link to comment Share on other sites More sharing options...
daiv Posted December 31, 2004 Report Share Posted December 31, 2004 check the speed on your cd drive. if its not 100x, how can you reach 100x? then account for conversion. that is minidisc write time, like everyone else said, not your whole system write time.

jadeclaw Posted January 1, 2005 Report Share Posted January 1, 2005 Daiv, the 100x is the difference of Hi-LP@48k transfer time compared to real time. It has nothing to do with the cd drive. The tracks must already present on the harddisk AND already be converted to Hi-LP@48k. Only then the 100x will be reached. And of course with a 1 GByte disc only. And I have to agree with Latexxx as well, in hp's case, the K6 is the limiting factor here. With an Athlon XP2000+ I get a 70min. CD into SS2.3 in about 6 minutes. Since it ends up as Hi-SP, transferring these tracks then onto a 1GByte disc takes another 5 minutes (~10 min. for a standard disc). Quote Link to comment Share on other sites More sharing options...
atrain Posted January 2, 2005 Report Share Posted January 2, 2005 cdroms don't come ay 100x - it's past the disc tolerance. even at 52x some cdrs will snap inside a drive. it's happened to me before Quote Link to comment Share on other sites More sharing options...
alieninhead Posted January 12, 2005 Report Share Posted January 12, 2005 Its definitely the K6 proccesor and the need to encode Atrac3 on-the-fly. Depending on your CD read speed, this could be an issue--but the bandwidth of an IDE bus tops out at a theoretical maximum (if I recall correctly..) 133mb/s. Faster than most CD drives today. Its something else thaz causing the bottle neck... Quote Link to comment Share on other sites More sharing options...

alieninhead Posted January 14, 2005 Report Share Posted January 14, 2005 Actually, to go further into the subject of CD-ROM speed...by my calculation if I am correct the fastest read/write speed a CD-ROM can have is 30MB a second or so.That is based off of 600kb a sec per 1x increase of speed. So..1024 in one MB, 52x600 is 31200/1024= 30.46875. My math skills do suck, but I'm pretty sure I got that part right. Anyone wanna correct me?~a.i.h.

megnez Posted February 15, 2005 Report Share Posted February 15, 2005 Cause I want to buy a Hi-MD this week I'm now looking for information about it.As I nowhere found upload times on Hi-MD I tried to calculate it...please correct me or inform me about your upload times, thanx!100x upload speed (of 48kbps coded songs), seems to be 4.8Mbps, doesn't it? That would be 0.6MByte/s, so it would result a upload-time for 1GB of approximately 28mins?Am I totally wrong or does it take so long?

ROMBUSTERS Posted February 15, 2005 Report Share Posted February 15, 2005 its 100x transfer from PC -- MD meaning it can transfer a 48kbps song at 100x real time (in ideal settings). This equates to approx 48*100 = 4,800kbps or about 600KB/s or about 0.6MB per second correct However this doesnt take into account seek time or TOC writing time which adds to it. People have had horror stories of writing full HiMD discs and that taking about 40+min Quote Link to comment Share on other sites More sharing options...
