Why there's difference in terms of performance between:
a) SanDisk Extreme SSD 120 GB SATA 6.0 Gb-s2.5-Inch Solid State Drive SDSSDX-120G-G25
b) SanDisk Ultra 120 GB Solid State Drive SDSSDH-120G-G25
for (a), MTBF is 2.5million hrs. Anyone can provide the
MTBF for (b)?
For (a), amazon url give 510/550Mbps write/read while
for (b), amazon url give 270/280Mbps write/read.
Both are SSDs, why such a big gap in performance?
For a, I refer to the url
For b, I refer to the url
Can both the models be inserted into Lenovo X220 laptop for
Win 7 boot-up ?
