THe DC S3700 isn't good as squential but the 520 or 525 series has the
problem that it doesn't have a capicator. We've used Intel SSDs since
the 160 series but for ceph we now go for Crucial m500 (has capicitor).
"Curcial m500 has capacitor", could you please give some sources about
that ?
Simply google but here:

Power-Loss Protection: In the rare event that power fails while the
drive is operating, power-loss protection helps ensure that data isn’t
corrupted. To supplement our power-sensing firmware protection, our SSD
engineers designed physical power reserves (capacitors) that are
specifically tailored to our NAND requirements and deliver enough power
to ensure data remains intact.
