example...New ssd drive, day by day working and after some time cells by cells go death.whether the dead cells lead to corruption/loss of data or a only reduction in capacity??? I need to buy new 30 pcs for my dtp workflow and look at intel 510 ssd.
Its highly depend of architecture of SSD. Some SSD`s have spare cells area, so for some time they could compensate cell disposal (no capacity loss), some SSD`s use special algorithms for writing data into cells, using error correction codes (no data loss), some have both kind losses simultaneously. And Intel use SSD controllers from many vendors. If I remember correctly, in 510 Marvell controller used, so it have some error correction, but no spare zone.
Just like with traditional HDDs, you can use SMART for monitoring drive health. ID 05 Reallocated Sector Count in RAW view will show how many cells of your SSD retired.
