The drive has worked absolutely flawlessly and the intel ssd toolbox shows full life and health. I have started staying over at my gfs place and began streaming movies from my laptop onto her xbox. So I've started to hit the ceiling in terms of storage on my laptop.
If I upgrade to a newer TLC SSD will I see a significant drop in performance? I think I'll only keep this laptop for another 2 years or so. I was debating upon the crucial m4, samsung 840, and samsung 840 pro. Although would I not see any performance gains without SATA3?
I would be content with the same performance as my Intel X-25M MLC. Better performance from even a TLC drive would be a huge plus. Thanks for the help.
"Although would I not see any performance gains without SATA3?"
if your system only has sata 2 then there will be very little performance to gained by going to a sata 3 drive. except the fact that the next system it is used in can take advantage of the sata 3 capability. the sata controller depicts the amount of I/O speed on the motherboard so sata 2 will only run at the max the controller can handle while a sata 3 controller can handle higher amounts of data. most drives cant totally saturate a sata 2 controler because of speed limitations of the controler on the disk its self. even if it is sata 3 capable.
"If I upgrade to a newer TLC SSD will I see a significant drop in performance?"
Not as long as the read/writes speeds are about the same. IOPS is the more common numbers to look at for performance differences between drives.
I'll let someone else chime in on the choices that would best fit your needs.
I'm a little confused about your use of the term "TLC SSD".
TLC is an acronym for "triple level cell". It refers to a type of memory. Samsung was the first company to use it in a consumer oriented ssd. The TLC memory is used in the Samsung 840 Series which is their mainstream value ssd. Samsung used a more traditional type of memory in their flagship 840 Pro series. I do not know of any other company that uses TLC memory in consumer oriented ssd's.
TLC memory is normally used in memory cards, media players, and mobile GPS so this is something new in the ssd market. A concern has been expressed about the longevity of TLC memory in the 830. There is no definitive answer yet.
According to the Lenovo datasheet the X201 has 3 USB ports. Have you considered an external hard drive as a possible solution?
