Comparison of the hundred dollar Costco Seagate 5TB USB & 8TB USB HDD on sale now

The 8TB drive is 3.5". The power requirements are 12V for motor, 5V for logic. 3.5" drives are available up to 14TB or so in capacity (at least, at your nearest retailer you might find them). Some of the larger ones than that, are only intended for data centers (host managed versus drive managed). The 5TB drive is a 2.5". It's the largest 2.5" they make. It runs off 5V only. 5V for motor, 5V for logic. Generally 2.5" drives try to draw no more than 1 ampere, and this occurs during spinup. The current consumed on the small 15mm tall 2.5" drives, drops back once they're up to speed. The 2.5" drives come in a variety of heights. 7mm & 9.5mm is useful in a laptop. The laptop bay is not big enough to support 15mm drives. The 15mm drives were made specifically for usage in portable external enclosures. It's also why you don't tend to find much information on 15mm ones, since they're not intended to be sold as "raw" drives at retail. As they don't fit in laptops, and nobody wants a steady stream of customers bringing raw 15mm drives back for a refund because they don't fit. External drives have a USB connector. Some drives used in such devices, the USB connector is part of the drive, and the drive cannot be "shucked" and removed for usage inside a SATA computer. Other external drives, there is a separate controller board which converts SATA protocol to USB protocol. Those sorts of drives can be taken apart and the disk reused. It's possible the 8TB Seagate mentioned, a 3.5", can be removed from the enclosure and reused. The warranty is likely void if the drive is used in this way (outside of its housing). Running the drive serial number on the warranty page, will show the drive itself in the bare state, has no warranty. The number on the housing could indicate a valid warranty exists for the entire item. Paul Hi Paul, Regarding o 5TB Costco Item #3005555 P/N 2R2AY1-570 (STHP5000600 on sticker) o 8TB Costco Item #8888881 P/N 1XAAY5-570 (STEL800401 on sticker) Here are photos I just snapped for you of the two Costco drives: o https://i.postimg.cc/MpjQMNM7/hdd01.jpg size & weight difference o https://i.postimg.cc/5tdFwgLZ/hdd02.jpg Costco packaging o https://i.postimg.cc/76XGrydk/hdd03.jpg Model numbers Thanks for that purposefully helpful information where I must comment that the sheer physical size & weight difference of these two Seagate devices is immense. o The 5TB Seagate drive weighs a puny 7 1/4 ounces all alone o The 8TB Seagate drive weighs a whopping 30 1/2 ounces all alone https://i.postimg.cc/MpjQMNM7/hdd01.jpg Side by side the sheer physical size difference is also huge: o https://i.postimg.cc/5tdFwgLZ/hdd02.jpg These are the respective model numbers of the two hard drives: o 8TB Seagate Backup Plus Hub P/N 1XAAP3-500 [aka Model SRD0PV1] 12VDC, 1A o 12VDC 3.0A Schenzhen Honor Model ADS-40J-12 12036EPCU Switching Adapter o 5TB Seagate Backup Plus Portable P/N 2R2APM-505 o https://i.postimg.cc/76XGrydk/hdd03.jpg What I love about the 5TB is it doesn't require an additional 12VDC power supply, which means, I would think, perhaps, maybe, it's more likely to work in a decade or so, but I'm not sure of the correct logic on that. Which is more likely to work in a decade or two from now? The 2.5" drives come in a variety of heights. 7mm & 9.5mm is useful in a laptop. The laptop bay is not big enough to support 15mm drives. I do not know how tall the 5TB drive is, inside. External drives have a USB connector. Some drives used in such devices, the USB connector is part of the drive, and the drive cannot be "shucked" and removed for usage inside a SATA computer. The possibility of being "shucked" makes a difference because we want this drive to work in a decade or two from now. Running the drive serial number on the warranty page, will show the drive itself in the bare state, has no warranty. The number on the housing could indicate a valid warranty exists for the entire item. 1. I went to the Seagate warranty page https://www.seagate.com/support/warranty-and-replacements/ 2. I enter the 8-character serial number from the Costco sticker. 3. Your Product = Backup Plus Portable == this is the 5TB Model Number = STHP5000600 Serial Number = xxxxxxxx Warranty Valid Until November 29, 2021 Your Product = Backup Plus HUB == this is the 8TB Model Number = STEL8000401 Serial Number = xxxxxxxx Warranty Valid Until October 10, 2022 I'm not so much worried about warranty as I am the basic stone cold logic of which drive is most likely to be still working a decade or two from now. -- On Windows newsgroups everyone is always helpful even if we don't like M$. |

While I completely understand your answer, you have to remember these drives are _external_ drives, connected via USB, for _backup_ purposes. I understand your problem, and have handled such issues in the past. While all the drives do not have much time in terms of power-on, they ALL will have many years of decaying electrical components (such as circuit boards, chips, and contacts)--which are required to make the devices work. THAT is your real problem. And is the ONE problem you have not addressed. Plan to transfer the data every 5-7 years, from the old media to a new media. The old stuff WILL be getting more fragile and subject to failure as time passes, so you want to replace the DEVICE before it fails--and renders the data stored on it irretrievable. Banks are required to keep customer info for seven years after each transaction. So, they use microfilm and microfiche, not electronic storage of any type. Courts are required to keep court records forever. They mostly use paper. Their records go back over 100 yrs. IMO, you need to think about what is needed vs what is cheap to do today. If the data is not that important, then who cares? It may make sense to subscribe to multiple online data storage and retrieval services and let THEM worry about how to store it. That is why you pay them. If they screw up, you can hold them responsible--unless their TOS says they are NOT responsible. In which case, why does anyone use them? |
