I knew they'd start dropping in price eventually, that's a great price for a 120Gb SSD.
However, it's 43.99 and with OCUK's postage charge it comes to £52.69
It's only USB2, not USB 3.
But for a budget build and gaining the advantage of having your OS on an SSD then it's pretty hard to beat.
11 months ago I bought my Corsair USB 3 120Gb SSD drive for around £120. It now costs £85.00
And 120Gb is perfect to take an OS, in fact as V_R pointed out it's more than enough.
As for OCUK, I would never rule out using anybody, if OCUK had what I wanted at the right price and nobody else was stocking it at the time I'd use them. I just wouldn't use them by choice, is all
I don't want to use Scan either, they crossed me, but they were the only ones stocking my Mionix keyboard a short while ago, good price, so Scan got my order. I'd rather have bought it from Kustom PC's but they didn't have any stock. So it goes.
