AS-SSD Incompressible Sequential Performance

The AS-SSD sequential benchmark uses incompressible data for all of its transfers. The result is a pretty big reduction in sequential write speed on SandForce based controllers, while other drives continue to work at roughly the same speed as with compressible data.

Incompressible Sequential Write Performance—AS-SSD

Since there is no compression involved, incompressible sequential performance doesn't bring up any surprises. Write speed is heavily affected by the amount of NAND and its speed but this is typical to all SSDs.

    So, you're saying Anandtech is unable to verify Samsung's power usage claims — completely.

    That's very interesting.

    "That line of thinking is flawed. If you're only catering to desktop users, why even present the power consumption figures at all?"

    Of course. This is a very interesting line of thinking, isn't it?

    1. Samsung provides only extra special "mobile" figures that are extremely low at .13 (830 512 GB) and .14 (840 512 GB).

    2. Samsung, if Anandtech is to be believed, is providing not particularly interesting data, since their charts apparently don't apply to mobile usage.

    3. According to Anandtech, desktop users don't care about SSD power usage and so Anandtech only cares about desktop SSD power usage (hence the existence of charts/comparisons/commentary).

    It's all quite fascinating.

    from article:

    "While 240/256GB is undoubtedly the most popular capacity at the moment...'

    Most 120/128's outsell their larger stablemates almost 2 to1 in some cases. 240/256's are the most popular to be REVIEWED cuz they pump out the best numbers. That may change n the future...say another year...year and a half.

    Can anybody who have dealt with manufacturers claiming for warranty.. what does warranty actually mean?

    Like we all know that the ssds fail without notice and without any reason,, so if i ask the manufacturer for a replacement of the ssd within the warranty,.. will they replace the drive?

    Performance does not matter to me all that much,,, but reliability of ssds not failing.. atleast for like 2-3 years of good use.. is what concerns me.. and ofcourse if manufacturers would replace failed ssds.

    Thanks
