Question What store device is more durable these days - HDD or SSD?

What device is more durable, long-lived? As far as I know - HDD is still better about it. What do you guys think/know?

Durable ? You gonna drop it on the floor ?

SDD would theoretically be more durable as in resistant to impact. HDD would last longer.

I don't consider either a means of backing up data tho, back it up to a read-only removable media, like DVD.

That is a bit of a tricky question as there are many different factors that will influence the outcome. Are you talking about active use (like as a main drive in a computer), or to copy data to and then put on a shelf? What about shock/movement (since you used the term durability rather than longevity)?

SSD still has a more limited life in terms of an actively used drive (limited read/write life of the chips) but this is still going to be measured in years. Also as SSD is still a relatively new and developing technology there is no real long term track record of it. Spinning disk on the other hand has been around for a long enough time that it is established as a media.

Ultimately though either one can fail unexpectedly for any number of reasons, so always have a backup of important data.

'SSD' is not something new.The 'SSD' has been around for years. Density as it has increased has provided smaller foot print drives. DRAM based 'SSD' are still used but with the NAND based 'SSD' you have the reliable backup without battery backup that is required for a DRAM based drive. DRAM based drives won't have wear problem as with a standard hdd. Access is much better with a DRAM based unit and has been used without difficulty. DRAM based are larger than the new 'SSD' based on current NAND technology but with the potential degradation. That problem is moot if you look at the numbers.

The hdd with increased platter speeds is one of the ways to have better throughput. Add to this the increased buffer space and the drives are still usable. With density increasing for memory we will see bigger and better DRAM based 'SSD' technology but not for the general desktop user at affordable prices.

If you purchase a high quality traditional drive for a server I'd guess it would outlast any ssd on the market in terms of actual use either mean time failure in hours or bit.

Until they make them out of rubber you can't exactly drop either of them.

They don't take bathes well.

Not long life after a fire control radar hits them, or lightning or esd.


disk, hdd, ssd
