Help with computer build...
vuzedome:
Unable to saturate Sata 2, I'm not expecting it to max out but it being a more expensive SSD should show at least some significant improvement compared to cheaper SSDs.
linx:
it does, but not where you'd expect. It's an enterprise grade/near server grade product. Uses better NAND chips, or at least different ones, SLC has ~ 10x the write cycles of MLC. It's not one for your average home user though, SLC is expensive but if you want SSD performance on a server it's your only option
Freedom Kira:
SLC doesn't mean anything. Have you looked at the R/W speed ratings on those? They're nowhere close to the levels I've seen on most MLC drives (they're typically about double the write speed and 30-50MBps more for the read). And SLC is theoretically supposed to be faster because each cell is dedicated to fewer bits.
At the moment I don't care much for having more write cycles, especially on a drive that small, which will quickly become obsolete and thus be replaced. On smaller drives, what matters the most is performance, even if it burns out more quickly. If the drive was over 500GB I would reconsider, as its lifetime would be a lot longer.
Just give it up, man - those drives are no better than a 7200RPM drive. I dare say a Velociraptor could outperform those poor excuses for SSDs. With more space, to boot. And when you bring SCSI HDDs into the picture, which easily outperform Velociraptors...
linx:
Yeah, the sequential R/W speeds are more in line with 1st gen SSD's - probally what they are. The current MLC drives are faster due to their new controllers. As I said before, they are not aimed at people like you or myself and more at places where they actually would wear a normal SSD out in 2-3 months easily. I eagerly await the day when 256-500GB SSDs are common and cheap enough to be bought by the average computer geek, I got used to an SSD and now find the 5400 in my laptop really unresponsive, that is . . . until I get reminded how much I paid for my 120gb drive lol
Freedom Kira:
If they write enough data to wear out a 64GB SSD that quickly, they're better off getting a bigger one for a similar price... Or RAID 5/6 together some HDDs. Even if you RAID together 8 250GB HDDs, the final price would be comparable to a single one of those WD SSDs.
Anyway, let's get back on topic here.
