SSD query

recently i've been asking few questions on spec etc mbp 15", , have come conclusion lower spec mbp ample me in terms of processor , graphics card, there's no point in paying £300 ($470) higher spec one. love ssd need 500gb minimum, , apple want £960 ($1500) upgrade tot 512gb ssd, i'm not prepared pay, going pay £120 ($188) upgrade 750gb 7200rpm sata drive.

however, i've been looking around internet , come across @ crucial http://www.crucial.com/uk/store/mpartspecs.aspx?mtbpoid=3d217106a5ca7304. costs £522 ($820) more reasonable imo. however, i'm new ssd's , have no idea what's classed good/fast drive. 1 @ crucial has read speed of 500mbps (sata 6gb/s), , write speed of 250mbps (6gb/s), considered fast, slow or average? how compare read/write speeds of 7200rpm sata drive? (anyone know exact speeds are?). mean when gives speed such 500mpbs, , in brackets "sata 6gb/s"?

also, if buy crucial ssd how trnasfer os x lion , installed software preinstalled drive new ssd one?

cheers.

i use www.anandtech.com reviews quite lot best, honest unbiased reviews on different ssd's available on market.

in terms of sata interface, there 2 types: sata2 , sata3. former has theoretical transfer rate of 3gbps , latter can perform (again, theoretically) @ 6gbps, chipset on system board. experience, performance of ssd fast controller controls it, performance figures can misleading. have @ review on link, give better idea of mean:
http://www.anandtech.com/show/5508/intel-ssd-520-review-cherryville-brings-reliability-to-sandforce

although boast either 3gbps or 6gbps, overall performance when directly compared other ssd's pretty big!


working @ intel, tend quite biased intel ssd's (as can imagine) intel ssd's run older firmware , looking more @ enterprise business now.

speaking, price of ssd's based around cost of nand memory used within ssd. current process sizes @ 22nm, , smaller process size, more nand chips can produced, driving down overall cost per gb. same brands, prices tend pretty same companies. biggest ssd have seen far 600gb intel 320 series ssd, looking @ paying near makes no difference $1000 it.

apple ssd's overpriced memory, , can better deal shopping around interweb similar-sized ssd's. might worth looking ssd/mechanical hybrid drives available - offer bigger volumes @ fraction of cost, , performance lot higher compared standard mechanical hdd's. when got mbp, stuck standard 500gb hard drive, way if decide upgrade, notice difference

regards transfering data, new apple can't answer unfortunately!
