I replaced a dead Hitachi 100Gb 7200rpm drive with a Transcend 128GB SSD several months ago in my Asus M6Ne laptop. I think it was around $380. Cheaper than the Runcore, no idea about the relative performance though. Still can't beat the deal I got with my 256GB Samsung SSD from Dell for $480.

Those features disappeared some years ago. Motherboards now have lots of control-enabled fan headers, which have more or less taken their place. If the 120mm fans were runnning at min before, then I;d say just run them at 5V -- there are many ways to do this w/o spending a penny. Thanks for the rep...

Antec TruePower 380 died

I bought an Antec Sonata case many years ago and it came with this TruePower 380 bundled in. It's been working great, 24/7 but yesterday I shut it down for an OS upgrade and it wouldn't come back on. The little green pilot LED on my mobo turns on, so the standby power still works, but nothing else. ...

The P256 is definitely a Samsung, and it's got impressively low power consumption as well as high performance.

re: cache size - kind of a moot point, there are no JMicrons with large cache. Therefore, if it's got a JMicron controller, it's best to avoid it.

The other way is for SSDs to make 16 or 32kb block arrays. This is more expensive, though, as that's a ton of tiny chips. But it would solve the problem quite nicely. Actually it just requires a simple reorganization of the internal array inside a flash chip. Unfortunately chip-makers are still mak...

If I had my choice after reading that interview I'd want a firmware that reduced the usable space of the drive noticeably so that wear leveling / controller optimizations would work better. Obviously they went for 30/32, 60/64, and 120/128 with the V2 but I'm thinking 26/32, 52/64, and 104/128 woul...

Flash storage devices should all support a Secure Erase command that can zero out the entire drive. It's a standard command in the ATA-8 specification, nothing special/proprietary about it. MTRON for certain supports it.

Something still doesn't make sense about all this. If the controller is really too stupid to reorder logically random writes into physically sequential writes, then caching alone wouldn't solve the problem. I.e., if you throw a long stream of random I/Os into a big cache, eventually it has to flush ...

i'm feeling a bit like jumping on the OCZ drive was a premature decision, but what the hell. The 160GB Intel drive won't be out for another quarter or two, so in the meantime, I'm still getting better read performance with my 120GB CoreV2 than any other notebook drive.

These days, 16MB of DRAM probably runs on less than a milliwatt. A capacitor would be enough to keep the buffer intact for quite a long time. Writing to flash takes a bit more juice, but I bet you could use a cap to handle this as well, so the cache would automatically flush when power was removed f...

Agreed, it's pretty stupid of SSD manufacturers not to include DRAM caches in their products. A cache would also allow the SSDs to have burst transfer rates equal to the interface speed, e.g. 300MB/sec on 3Gbps SATA2. Given how common 8-16MB caches are in current HDDs, there's really no excuse for it.

NAND flash can generally be written in sectors of 512 bytes at a time, but if you need to rewrite existing sectors they have to be erased first, and erasing is generally done 2MB at a time. So, if you're only rewriting a region of data that's only part of a 2MB block, the whole thing has to be read,...
