Samsung 1.5 TB drive
Does anyone have any idea when Samsung will start selling 1.5 TB
drives? Thank you in advance for all replies. -- Whenever I hear or think of the song "Great green gobs of greasy grimey gopher guts" I imagine my cat saying; "That sounds REALLY, REALLY good. I'll have some of that!" |

I have no idea about timelines, but there appear to be two models in the offing: http://www.samsung.com/global/system...2eg_rev0.2.pdf One is the HD153UI with 16MB cache, the other is the HD154UI with 32MB cache. The Spinpoint F2EG model series has a "MAX. 500GB Formatted Capacity Per Disk", so that would suggest a 3-platter 1.5TB drive. However, the images on Samsung's web site show 2-platter drives: http://www.samsung.com/global/system....5_525_330.jpg http://www.samsung.com/global/system....5_525_330.jpg I'm wondering why Samsung is not yet offering a 2TB drive. Seagate's ST31500341AS 1.5TB drive appears to have 4 platters, so it stands to reason that Samsung should be able to fit 4 x 500GB platters in the same form factor. Instead of playing catch-up, Samsung could be taking the lead ??? Another peculiar statistic is the weight: Weight (avg.) 500GB 470g 1TB 610g 1.5TB 650g A 1TB drive with 2 platters weighs 140g more than an 0.5TB drive with 1 platter, yet a 1.5TB drive weighs only 40g more than a 1TB drive. I would have expected it to weigh 750g if it had 3 platters. - Franc Zabkar -- Please remove one 'i' from my address when replying by email. |

Maybe Samsung (being a large engineering enterprise with expertise in many fields) is more concerned about reliability than taking the lead? They can afford it.

I would have expected it to weigh 750g if it had 3 platters. Probably a lot of weight from 0.5 to 1GB goes into a bigger spindle and head assembly and a larger spindle motor, that is then only used in part in the 1TB drive. Arno |

Even the 500GB model has the same acoustics. I would have thought that the 1.5TB model would have 3 platters, with a consequential reduction in weight and power consumption. Something doesn't look right ... Is it possible that the 1.5TB model has 4 platters with lower data density? OTOH, the sustained data transfer rate is identical, so wouldn't that suggest identical data densities? - Franc Zabkar -- Please remove one 'i' from my address when replying by email. |

No reason why the number of platters should make any difference to the acoustics if the same rotation motor is used. I would have thought that the 1.5TB model would have 3 platters, with a consequential reduction in weight and power consumption. Something doesn't look right ... Yep, your understanding of how drive familys are done. Is it possible that the 1.5TB model has 4 platters with lower data density? OTOH, the sustained data transfer rate is identical, so wouldn't that suggest identical data densities? Yes. But it could well have an unusable platter, tested to be not worth using. |

Obviously you didn't fill it will data. 1.5TB weighs 36g.

No reason why the number of platters should make any difference to the acoustics if the same rotation motor is used. The motor makes practically no sound. Sound sources (during non-seek) is air turbulences caused by the platters and vibration from the platters not being exactly centerd. Both go up with more platters. Arno |
