Really how about you tell us what End-to-End Data Protection stands for & it's utility in real world conditions, not to mention that the 320 is EOL & a 3Gbps (previous gen) SATA II drive
What about End-to-End Data Protection? Just the SSD alone cannot provide this; it means the entire chain from provider to consumer is protected - usually by ECC or Parity protection.
Whether the Intel 320 is not produced any longer or whether it is a SATA/300 drive, is not relevant. The topic is about the
most reliable SSD released in the last 5 years - not the fastest or most recent. The Intel 320 fits this requirement the best of all consumer-grade SSDs i am fairly sure.
Not to mention the Intel 320 can still be bought at some places, just because it has such a proven track record it is still a very good choice for many tasks. The latency is very low because this SSD has SRAM buffercache instead of DRAM buffercache which most modern SSDs use. But its sequential write performance is particularly low, even for a SATA/300 SSD.
But maybe as you know, SSDs feel so fast not because their sequential speeds are 2 to 3 times as fast as HDDs, but because their random read performance is 100 to 1000 times higher than HDDs. The irony is the lowest number of 20MB/s blocking random read performance is the prime reason SSDs feel so snappy compared to harddrives. The highest numbers are not all that important, especially not the write performance - at least not for typical workloads SSDs are used for. Benchmarks distort this because they throw a shitload of writes that does not tally with real-life scenario's. Who writes 1GB/s to his SSDs regularly? That is crazy.
