It's time for the PCPer Mailbag, our weekly show where Ryan and the team answer your questions about the tech industry, the latest and greatest GPUs, the process of running a tech review website, and more!
This week, Allyn's back to tackle more storage questions:
00:28 – What is bit corruption?
08:02 – Was the Samsung 840 EVO ever fixed?
14:57 – Retirement age for hard drives?
15:50 – SSDs with only TLC NAND?
19:30 – HDDs with multiple heads?
23:03 – Upcoming Samsung NVMe SSDs?
25:55 – Allyn's storage setup?

On the Samsung 840 EVO how
On the Samsung 840 EVO how did all this Refreshing affect the life of the 840 EVO and did Samsung add any extra warrenty on the SKU. Or is there usually enough over provisioning for an SSD drive to make its rated warrenty period?
Also can SSD drives with TLC NAND Pages that are getting a little long in the tooth be made to treat the TLC NAND as MLC(2 level) NAND, or even use the NAND like SLC and only store one value and get more life out of a NAND Cell that was originally use as TLC but can no longer reliably store 3 states?
When will there ever be SSD drives with some XPoint cache on the SSD to help improve the Average larger pool of NAND’s(Mostly with TLC/MLC[2]) slower read/write speeds?
XPoint Cache can be much larger relative to the size of DRAM cache on an SSD and XPoint cache is also NVM like NAND so there is some level of extra value in XPoint as an SSD Cache choice over DRAM, extra value in XPoint’s Density realtive to DRAM’s density and XPoint’s speeds being the closest to the speed of DRAM, with XPoint Cache being NVM just like NAND.
Western Digital has announced that it will be adopting the open RISC-V ISA for it’s future devices and Controllers/CPUs that will be based on the RISC-V ISA. This will allow for Western Digital/others to extend the RISC-V ISA with specilized RISC-V ISA extentions more tailored to Hard drives/SSDs or other storage systems(NAS, Other systems).
So do you think that this is the start of RISC-V maybe even being used for general purpose CPUs in competition with not just ARM ISA based controllers/devices but other CPU/Controller makers ISAs used on many devices?
Nvidia has been using the RISC-V ISA for its FALCON(FAst Logic CONtroller) line of controller used on Nvidia’s various products.
This question is for Josh.
This question is for Josh.
Is there any such thing as CPU redundancy ? I know that 2 socket motherboards are common in the enterprise. Is it just there to leverage more compute and for better heat dissipation or does it serve any other purpose beyond that?
Thanks,

Is this the place to ask
Is this the place to ask questions for mailbag, or is there an email to write to?
Heh good question :-). I’ll
Heh good question :-). I'll find out for you.
EDIT: Official answer is that the preferred way is to leave a comment on the Mailbag YouTube video or Mailbag article comments section.
Thanks!
Thanks!
Why do GPU manufacturers need
Why do GPU manufacturers need to update their drivers every time a new game comes out? Isn’t there a standard, known way to interact with the hardware (whether it be via DX11, DX12, Vulkan, etc.) that game developers need to adhere to? Wouldn’t fiddling around with the graphics setting per game at the driver level be considered “cheating”?
