5TB Drives

[matt100]

Ah Seagate harddrives start clicking pretty much within the first week then die within a month or two.

thats a remarkably bold load of balls you've posted there?

I've had a 2tb freeagent that's been used a lot and chucked around a fair bit, no issues at all?

I am a bit concerned though, I use it to back up a 2tb internal drive which now has only 300gb spare which was 400gb about a month ago. If I'm going to keep mirroring my storage for backup this is going to get very expensive...

About blinkin' time, the technology has been held back due to the floods but I won't be getting a second mortgage for one.

Yes, every single one of them made do this.. FACT.

10TB = 10,000,000,000,000 bytes. Now divide by 1024 (2^10) 3 times (once = k; twice = M; thrice = G; 4 = T).

Ahh brill thanks

Im waiting on the Crucial M4 5TB SSD...

So if 5TB works out at 4.54TB after formatting then how does 10TB work out at 9.3TB, something doesn't quite add up

Think you'll be waiting a little while then

Aye, but given that I am perpetually broke it hardly matters

i always thought that the more you buy the cheaper it gets ( slightly ) but bigger hdd's get more and more expensive, ocuk have a 2tb hdd for £94.99 but the cheapest 4tb hdd is 269.99, so if you buy the 2tb hdd's you could get 3 of them ( 6tb ) for only 284.97 less than £15 quid more for 50% more space.

That is because the 4TB drives are the top end, you will always pay a premium this. I suspect by the time 5TB drives will be released, the prices of the 4TB drives will have plummeted.

9.3TB is the SI TB, ie 1000GB = 1TB.

9.09TB is the correct computer amount.

I think you're still missing the point here.

9309 GB is not reported as 9.3TB, it's reported as 9.09 -- you divide by 1024 to get this number.

It's also nothing at all to do with formatting, it's do to with the HDD marketing people using true SI terms and operating system vendors (although I believe Apple have gone and changed this) using binary prefixes.

The current 4TB drives have 4 1TB platters, a 3.5" drive can have 5 platters so 5TB drives could be released anytime the manufacturers want.

Well thank you for thinking I am missing the point.
Of course I have only posted up questions using other people numbers.

Sorry, I'm still in harsh code review mode from work.

Basically, your hard drive is going to be 10,000,000,000,000 bytes or as close to it as possible. The manufacturer will tell you this is 10TB, and they are correct as far as physicists, chemists, etc. are concerned; but not where computer science people are. We see that as (10^12) / (1024^3) GB which is 9313 or thereabouts. To go from GB to TB, we divide by another 1024, giving the value of 9.09TB as given before.

It's slightly confusing as has been mentioned before, so the physicists recommended we call our units GiB and TiB etc (pronounced Gibibytes and Tebibytes) but we can't now go back and change say Windows XP to show TiB, so we're stuck with the confusing terminology on older systems.

Wikipedia has a decent article on this if you're still stuck.

I don't think I'll ever fill 5tb!

 

[Imy]

great aslong as they dont go kaput!!!!! 5tb of data is gonna be a nightmare to back up

It's quite easy to backup 5TB of data; just buy a 2nd 5TB disk!

I currently have (filled) 4TB of storage with 1:1 backup and want to increase this to 10TB.

I use a NAS with 2 x 2TB disks for primary storage and a spare PC packed with old drives for backups. I'm not happy with the performance of the NAS for certain tasks so want to move my primary storage to my main PC and use the NAS for backups and streaming only.

The reason I want 5TB disks over the currently available 4TB is because I've only got a limited number of spare SATA ports in my main PC and I want to keep things simple and not mess around with add-in controllers again. The NAS has 3 further available slots so I can just put another 3 x 2TB drives in there to make the 10TB.

Is there a calculation you do to find that out?

yeah its always 93%

 

[Surveyor]

Is there a calculation you do to find that out?

For GB to GiB it's 93.13%

For TB to TiB it's 90.95%

For TB to GiB multiply by 931.32

if you format it it under MBR Master boot record, its better as you can format it as 1 big drive if its 5TB Mine is showing up as 4.54TB and the beauty of it is that as MBR it works with a MacBook and windows as well.. which runs under fat32 file system but in a pc it shows up as NTFS

 

[Imy]

Nice thread revival...

From my OP to yours I've now filled a further 10TB and am looking for bigger disks again

Unfortunately Synology are saying pretty much all 6TB and above disks are incompatible with my NAS. So much for it making life easier!

 

[Tazzionator]

have you ever thought about Raid?? I did to begin with... but if 1 drive fails then all your data has gone, because raid stripes the data across the drives.. so this is why I opted for the bigger drives.... in 1 unit...
