If the drive can sustain an average 200MB/s, it will take 31 days of sustained max write speed to complete its rated 550TBW endurance. While this isnt a situation that will occur under almost any circumstance, it outlines the worst case which you can work from. ie your business will fill the drive (or equivalent) once for each 50 full 8TB of reads, all maxing the drive speed continuously. A pretty outlandish hardcore use. This will meet the endurance rating in a bit over 50 months, just over 4 years. In reality 550TBW will hardly ever be met in 10 years by which time it will have been replaced. Also, The above isnt worst case, the drive can be expected to receive far worse punishment than sustained writes with very little seeking. 550TBW with all the seeking a database server will encourage, as will be its design scope, shows the drive will be pretty hardcore. If it is proven to withstand its rating this drive is rather good! It should easily exceed the 5 year warranty. Lets hope its transfer rates are high too.

Is this supposed to be impressive? Samsung 870 QVO 8TB is rated for 2,880 TBW and it's only QLC nand. But most importantly HDD and SSD speeds are world apart. Hard drives are like dinosaurs.

Odd someone has to explain this for you.

errrrr.......

Not sure what the TBW is, but I've had a Toshiba 8TB NAS HDD for a few years now 😛

TBW is TerraByte Writes or TerraBytes Written.

I might be wrong but IIRC when they state a TBW for mechanical drives it is a yearly measure, not a lifetime one. How many years that covers, I dunno.

So are you going to explain why your precious hard drive is so good? Not that I care about hard drives in 2021 but now it peaked my curiosity what's so special about this dinosaur hard drive.

Naa, I'll let you work it out 😉

Never heard HDD measured this way before. I thought with the mechanical parts, MTBF is more relevant??

Well, with respect, I'd say one significant advantage would be that the unit price on this drive is reportedly $240 USD. I honestly don't know, myself, but I'd genuinely be surprised if an 8Tb SSD wouldn't be at least three times that amount. Not suggesting you don't realize this, but there remains, for many, a genuine need for mass-storage for data that doesn't really need to be accessible at SSD-like speeds. This drive looks like a good candidate for that purpose.

Obviously I know price difference between SSD and HDD, but some previous posts hinted that this is one amazing HDD for some reason (didn't give the reason why). So I thought there was something more special about it than the price difference HDD vs SSD. Actually you can pick up Samsung's 8TB SSD for 550Eur frequently during discounts. Yes it's still more expensive than 8TB HDD, but you'll get so much more IOPS and no HDD noise or vibrations. No vulnerable spinning parts!

Curious how come and they used the Toshiba name.

Definitely strange way of endurance rating a HDD. Basically what they're saying is write heads can take 550TBW writes per year at 24/7 loading, probably around 5 to 8 year mark? on average?
