back to article What did the one Toshiba desktop SSD say to the other? Our cell size has shrunk

Toshiba is busily upgrading its PC/workstation SSD line at the same time as it’s scaling back its PC product activities. Its Q300 and Q300 Pro consumer/gamer SSDs were announced in September last year. The Q300 was a TLC (3bits/cell) unit storing 120, 240, 480 or 960GB of data while the Q300 Pro used MLC (2 bits/cel) NANd and …

    Interesting "lifetime" usage

    The lifetime for the new "Pro" is 640 TB writing for a 1TB drive.

    So, each bit is expected to be able to be written 1x/day for 2 years and then its a brick? Yeah, on average, and I know there are a lot of wiggles, bits and bytes, but given that this is almost double the previous reliability, is... intriguing.

    Looking at usage in a NAS, where parity is striped, this could mean lots of writes even in mostly constant data, due to blocks of new parity bits. Yes, its all about reducing risk, spinny disks are inherently a single point of failure, like motors, arms, etc, suddenly can render the entire disk dead. SSD at least dies (in theory) slowly, and (again, in theory) has built in RAID-ish redundancy, so one would like to believe that a drive nearing its EOL can still have remaining data read, possibly at the cost of losing free space.

    But, there is still the single failure point of the SSD controller, etc.

    I propose a new standard. Lets permanently punch the bits onto stacks of paper. That way, we can trust it. Except the 2000 Florida ballots.
