USB3 Solid state drive
#5
I just bought an internal 512Gb SSD, but its for a work machine which needs speed.
I don't think I would get away with justifying a 128Gb USB SSD for myself - unless I refer to it as something else on my expenses

Ive gone through THREE SSDs.
ALL failed - data gets BLIZTED . Bad controllers. And these were Samsung.
Ive gone back to slow HDDs.
When the SDD ran, was about twice as fast as my sata2 HDD. Access times were the most impressive. Failure and losing work was not impressive.
Im hanging back a few years until they sort the controllers out. Apparantly, its to do with variable voltage and the controller just doesnt handle it.

As an ordering (best to worst) for an OS/apps/etc drive for a normal user, the consumer 120/128GB SSDs rank -
1. V3 max iops - 3Xnm nand gives a significant longevity advantage.
2. Corsair F3 GT - very slightly faster than the max iops, but only 2Xnm nand.
3. Corsair Performance Pro - faster writes than the M4 & uses 3Xnm nand - but x amount of the extra longevity of the 3Xnm nand is used up by the additional write speed.
4(a). Crucial M4 - 2Xnm nand & slower writes than the Pro - generally faster than the normal V3 in heavy i/o situations.
4(b). V3 (normal) - 2Xnm - generally faster than the M4 in more normal i/o situations.
5. A3, F3 (normal), etc - slower 2Xnm async nand leads to the worst performance of the bunch - it's only advantage, imho, would be for a cheap R0 setup.
(1, 2, 4(b) & 5 being SFs - whilst 3 & 4(a) are Marvell based).
[NB whilst not an exclusive list, i've ignored the intel 510 (as it's too expensive for what it is for a general consumer choice - it uses 3Xnm nand & a Marvell controller, but is slower than the Pro & M4), the Samsung 830 (as it's a so-so drive... the only advantage being that it appears to be 2nd best for non-trim) & the Octane (as it's a disappointing drive - though the 2nd gen 'might' be interesting).]
