I currently have a 250GB HD with Lion installed in my MacBook. It's all good but a little slow (it's 5400rpm I think) and my space is running out so, not content with cutting down my 100GB collection of HD media, I want something bigger to pile my files onto. A faster drive would be nice but it's not at the top of my list, I just want a reliable drive with a lot of space for a reasonable price. Since I already have a Western Digital drive, I'm currently thinking about this - same model line (AFAIK) and same speed but 500GB for £60 seems good to me. However, if anyone can recommend a better drive I'm all ears! I looked around myself but most of the stuff has mixed reviews, I don't really know what manufactures and models are considered reliable My budget tops out at around £100 and I'd prefer to order from Amazon UK because I trust them but another reputable UK retailer is fine too, and I may go a little over that budget for anything which provides me with terabytes Thanks!
