The Samsung 840 Pro and the Kingston HyperX 3K in a durability test of Tech Report two petabytes of writes, survived. They are the last two ssds stand, four other discs were faced with problems after writes hundreds of terabytes.
The Samsung 840 Pro 256GB also has after the writing of more than two petabytes, or two thousand terabyte, no errors that cannot be repaired. However, there are now 5591 re-allocated sectors, and seems to write something to take off, says Tech Report. The site considers it not impossible that the solid state the three petabytes.
The Kingstons HyperX 3K 240GB has thanks to DuraWrite compression of the SandForce controller actually 1,4 petabyte of writes processed. The disk has only 31 re-allocated sectors, which is equivalent to errors in only 124 megabytes of flash. However, already appeared to reach 1PB of writes two fatal errors. There is no decrease of the writing speed.
A second HyperX 3K drive stopped functioning after the writing of 728TB and this drive was the compression bypassed, making the test more fair went towards the other participants. The Intel 335 Series kept it after 750TB and the Samsung 840 took it to 900TB, although much earlier problems appeared, including fatal. The Neutron GTX from Corsair did a total of 1.2 PB of writes to the drive gave up the ghost.
Tech Report the influence of the vulnerability of flash memory to demonstrate with the test. The site notes that all of the disks to the limit of the lifespan that the manufacturers in their specifications said they have exceeded and that the ssds much more write-actions could withstand than the average user will generate.
