OCZ Vector 180 SSD

A lot of time passed since I bought Intel X25-M SSD. From that time it server me great. After more than five years there is 1 realocated sector, wearout level is second time on 98% (got fixed by FW update to 100%) it has a runtime of almost 2 years. The question is obvious - why to change it? It has "only" Sata 3.0 Gb/s and 80GB got somewhat tight place. Why did I choose the OCZ Vector 180 and not e.g. Samsung 850 Pro? Well I think Samsung is over marketed (10y warranty for SSD? Really? What for?), maybe I like more Japan (well OCZ is not Japan) than Korea. OCZ seems a less feature and less error prone product, OCZ SSD GURU utility supports Linux.. this is it. :)

Toshiba OCZ Vector 180

This is "long life" branch of OCZ SSD drives. It has higher warranty (5y) and MLC cells that are less prone to wearout than TLC.

/dev/sda:
Timing cached reads: 3118 MB in 2.00 seconds = 1560.24 MB/sec
Timing buffered disk reads: 1310 MB in 3.00 seconds = 436.51 MB/sec

Interesting is the graph, showing there is some "step" in the performance.
