Yup...size does matter with ssds...lol The amount of over provisioning also plays a role re: endurance...the 40GB Kingston (Intel X25-V) is a prime example, afaik it has 64GB of nand on board. As a rule I run all my raided drives with 33% OP and my OS drive at 28%.Quote:

As fast as the 830 is, it's equivalent to the 64GB M4 on a speed per GB basis.
Right u are...I some-what remembered that there were some older intels with lotsa OP...just not which ones.

Do you know how much nand these drive actually have? If I remember correctly the Intel controller has 10 channels, but just half are used in the V models? I still have a couple of the Kingston versions flashed over to the Intel firmware so they have trim. Not that it does any good as they are in a raid0 situation. Great little drives.Quote:

Yes, the Vs have 40GB onboard, occupying 5 channels. The 311 is the same way, but the 320 40GB has 8 GB of redundant flash for its parity scheme.Quote:

I love that the Samsung 830 has maintained such a high speed over such an extended write time. That little Kingston just won't give up either. Great thread.

Thanks! That drive needs all the encouragement it can get.Quote:

it IS SLC NAND... so it's not really that ridiculous
And it's got 80GB of 50nm SLC at that. In reality, you should get closer to 300K PE cycles out of it.Quote:

300K PE cycles would be ~8.65 years of endurance... in which alot of things could happen. The end of the world could come, or some meteorite could strike it... or Mrs. Bat with a hammer :DQuote:

Most drives are up to date, canthearu's drive is based on the report from the 16th.

Drive has finally reached it's official worn point. It has been a good run, and drive is running a bit faster then it did when I first started it. Hopefully I can at least double the amount of written data. Unlike the earlier corsair force 3 .... Wear range delta has remained very well controlled, which may improve the eventual life of the drive.
Looking through the SMARTLOG data, the drive hit MWI 10 at:
446,307 GiB Host Writes (F1)
333,083 GiB NAND writes (E9)
