I understand that the raw value of the Power Cycle Count attribute in SMART data is used to record the number of power cycles. However, I can see the normalized and worst value is both 98, instead of the usual value 100 used when it's meaningless or ...
Before I ever ran `smartctl -t vendor,0x40 /dev/sdX`, the Timed Workload attribute data are as follow:ID# ATTRIBUTE_NAMEFLAGVALUEWORSTTHRESHTYPEUPDATEDWHEN_FAILEDRAW_VALUE226Workld_Media_Wear_Indic0x00321001000Old_ageAlways-65535227Workld_Host_Reads_...
So what's the requirement of DevSlp after all? Do I need a specific generation of CPU or explicit support from the PSU, or maybe even the SATA power cable? Or is it mainly about the PCH and the motherboard?
What does attribute E2h, E3h and E4h represent? Apparently since the second gen (34nm), they represent some "Timed Workload" thing, but they don't in the first gen (50nm).
Total NAND Writes of my 240GB 530 used to increase 223 per pass of full-drive random-fill (which is expected, since 468862128 * 512 / 1024^3 = 223.57 GiB). Now it increases 236 per pass...I wonder where comes the extra 13GiB NAND Write, and why it su...
I know right, because "Cryptographically erase data" only apply to those with "AES 256-bit Encryption" (non-OPAL one; and maybe some models do 128-bit, idk). It's essentially regeneration of the encryption key.And that's why I think that SE and ESE a...
I doubt that ANY SSD would "conform" with ATA spec when implement normal erase mode (which is either 0/1 filled: http://www.t13.org/Documents/UploadedDocuments/docs2013/d2161r5-ATAATAPI_Command_Set_-_3.pdf http://www.t13.org/Documents/UploadedDocumen...
I always do (E)SE with hdparm in Linux. I never noticed any difference (their own speed / the write speed they "produce") between the two on the G1.I don't think it's really strange though, because I never saw any vendors stating really clearly what ...
