I bought this drive with the expectation that it might help me get through another year or 2 with my ancient work laptop which is a Dell Latitude D620 with 4GB RAM. I can't comprehend the difference this drive made in the speed and usability of the system. It performs at least 500% better in all aspects now. Even with the laptop only supporting SATA 1 which only used around 25% of the performance this drive offers it still just smokes. Boot times went from 4 minutes to about 45 seconds with Win7 SP1 32-bit. I mean I use SSD's in my main system at home which is a beast so I know what these drives are capable of but had no idea they could breath new life into a 10 year old laptop like this. I believe the bulk of the improvement can be attributed to the increase in random read/write performance as seen in the benchmark results below, from 0.5 MB/s to 25-40 MB/s is drastic. If you're on the fence about getting a SSD to help an aging laptop or desktop I say go for it and you will not be disappointed.
I did some benchmarks using CrystalDiskMark 4.0.3:
Original drive:
Sequential Read (Q= 32,T= 1) : 24.695 MB/s
Sequential Write (Q= 32,T= 1) : 25.088 MB/s
Random Read 4KiB (Q= 32,T= 1) : 0.484 MB/s [ 118.2 IOPS]
Random Write 4KiB (Q= 32,T= 1) : 0.642 MB/s [ 156.7 IOPS]
Sequential Read (T= 1) : 24.747 MB/s
Sequential Write (T= 1) : 24.957 MB/s
Random Read 4KiB (Q= 1,T= 1) : 0.431 MB/s [ 105.2 IOPS]
Random Write 4KiB (Q= 1,T= 1) : 0.624 MB/s [ 152.3 IOPS]
Samsung 120GB SSD:
Sequential Read (Q= 32,T= 1) : 130.416 MB/s
Sequential Write (Q= 32,T= 1) : 125.590 MB/s
Random Read 4KiB (Q= 32,T= 1) : 26.479 MB/s [ 6464.6 IOPS]

Sequential Read (T= 1) : 115.557 MB/s
Sequential Write (T= 1) : 120.372 MB/s
Random Read 4KiB (Q= 1,T= 1) : 22.022 MB/s [ 5376.5 IOPS]
Random Write 4KiB (Q= 1,T= 1) : 35.948 MB/s [ 8776.4 IOPS]
