yips ..... noticed that ALSO; however my curiosity from triggered via sourcing of new SSD drives & looking at prices from Seagate/WD ... of MAJOR MFG'rs of Platter drives which lead me to this article about MTBF from Seagate
I am usually not much influenced by 'lower price' and often choose QUAILITY. Thus the MTBF and or AFR is on uttermost importance for me. MTBF calculations done to a world-wide agreed standards and format of info is usually uniform layout. SO "Apples to Apples" comparision is much easier.
Other reasoning I use = the WARRANTY issued on NEW PRODUCT eg Seagate has some drives as 5 yrs and others at 3 yrs. NOTE - The YEARS = from DATE OF MANUFACTURE, and not from date of sale. - which is what had been the norm in the past!. In few of my past purchases from NEWEGG (from where I generally get most of my laptop items) I have RETURNED THOSE HARD DRIVES which were over 3 mths OLD!! and they always have agreed to give FULL REFUND and or negotiated a even LOWER PRICE if i wanted to keep those drives. So BEWARE the cheap cheap prices of 5 YR Warranty drives!
I also used the Acronis tool you talking about - for me its 'inconsistant' reading is not reliable - I used to use such tools that was in past avaliable from Hitachi but also no longer kept Up-to-Date - still in DOS format! however it does give consitant reading from ONE BOOT numbers to NEXT....Hitachi's Tools am told by their support pple is NO LONGER VALID and they dont even use it!!
For me the SSD RELIABILITY and or LACK OF is major issue. I had 3 SSD from intel jsut die - and one was so bad that I sent the whole Lenovo laptop (x220) back for full refund. Even lenovo depot repair pple seem to imply that they not sure they would want to use intel SSD for 'heavy' / industrial applications....so SSD = for me = not ready for HEAVY BUSINESS USE YET= only for 4-6mths per drive!!!
