SSD’s reach two petabytes of writes in endurance test




The Samsung 840 Pro and the Kingston HyperX 3K survived by a durability test TechReport two petabytes of writes. These are the last two SSD’s holding out, four other disks facing difficulties after writes hundreds of terabytes.

The Samsung 840 Pro 256GB also after writing more than two petabytes, or two thousand terabytes, no errors that are beyond repair. However, there are now 5591 re-allocated sectors and the writing seems to take something off, finds Tech Report. The site does not consider it impossible that the SSD will get three petabytes.

The Kingstons HyperX 3K 240GB has thanks DuraWrite compression of the SandForce controller actually 1.4 petabytes processed writes. The disc has only 31 re-allocated sectors, which is equivalent to errors in only 124 megabytes of flash. However, there appeared already before reaching 1PB two writes to irreparable errors. There is no decrease of the writing speed can be observed.

A second HyperX 3K drive stopped functioning after the writing of 728TB and the compression was circumvented in this drive so that the test was fairer to the other participants. The Intel 335 Series held the post for 750TB seen and the Samsung 840 made it to 900TB, although much earlier problems appeared, including irreversible. The Corsair Neutron GTX knew total 1,2PB work on writes off for the drive died.

TechReport wanted to show the impact of the vulnerability of flash memory with the test . The site notes that all disks the limit of life that the manufacturers in their specifications indicated have largely exceeded and that the SSD could stand much more write-actions than the average user will generate.
