AW: [Sammelthread] SSD Kaufberatung, Troubleshooting und Begriffserklärung
Wenn ihr die Wahl zwischen der c300/m4 oder Vertex2/Corair Force 3 hättet, also Marvel oder der neue Sandforce Controller, welche würdet ihr empfehlen?
Beide habe ja Vor und Nachteile....
Es kommt drauf an was du damit machst.
Wenn du maximale Leistung immer haben möchtest + Trim was richtig funktioniert dann die m4 / C300.
Durch die 25 nand nur noch 3000 schreib cycles andstatt 5000 wie bei einer mit 34 nand.
Allerdings gefallen mir wie bei der Vertex 3 / M4 die 4k Werte mal überhaupt nicht.Da ist ja meine kleine Vertex 2 60 E 34 Nand sogar schneller.
Habe mich auch nun 2 tage extreme mich beschäftigt und rate dir eine C300.
Falls du aber wie auch verrückter auf deine SSD rumschreibst und vollpackst ect.Dann SF Controller.Am besten mit 34 NanD
Du willst für dein Geld das Optimum + Maximale Leserate C300

Zitiere:
Back to Micron though, for the 128GB, 256GB and 512GB capacities the endurance specification of the C400 is 72 terabytes TBW (same as the C300). Over the expected 5 year life of an SSD, that means a user could write 40GB of data to the drive every day, which unless you like to re-download your games from Steam every time you play them, is a number unlikely to be attained by any but the most extremely active users. The value-oriented C400v 64GB posts an endurance spec of 36 terabytes TBW, which covers users for 20GB of writes every day for 5 years.

Approximately 90% of what OCZ ships in the Vertex 2 and 3 is using Intel or Micron NAND. The 34nm Spectek parts pictured above are rated at 3000 program/erase cycles. I've already established that 3000 cycles is more than enough for a desktop workload with a reasonably smart controller. Given the extremely low write amplification I've measured on SandForce drives, I don't believe 3000 cycles is an issue. It's also worth noting that 3000 cycles is at the lower end for what's industry standard for 25nm/34nm NAND. Micron branded parts are also rated at 3000 cycles, however I've heard that's a conservative rating.
If you order NAND from Spectek you'll know that the -AL on the part number is the highest grade that Spectek sells; it stands for "Full spec w/ tighter requirements". I don't know what Spectek's testing or validation methodology are but the NAND pictured above is the highest grade Spectek sells and it's rated at 3000 p/e cycles. This is the same quantity of information I know about Intel NAND and Micron NAND. It's quite possible that the Spectek branded stuff is somehow worse, I just don't have any information that shows me it is.
OCZ insists that there's no difference between the Spectek stuff and standard Micron 34nm NAND. Given that the NAND comes out of the same fab and carries the same p/e rating, the story is plausible.
