"Limited Edition" SSD Has Fastest Storage Speed

Vigile writes "The idea of having a 'Limited Edition' solid state drive might seem counter-intuitive, but regardless of the naming, the new OCZ Vertex LE is based on the new Sandforce SSD controller that promises significant increases in performance, along with improved ability to detect and correct errors in the data stored in flash. While the initial Sandforce drive was called the 'Vertex 2 Pro' and included a super-capacitor for data integrity, the Vertex LE drops that feature to improve cost efficiency. In PC Perspectives's performance tests, the drive was able to best the Intel X25-M line in file creation and copying duties, had minimal fragmentation or slow-down effects, and was very competitive in IOs per second as well. It seems that current SSD manufacturers are all targeting Intel and the new Sandforce controller is likely the first to be up to the challenge."

Re:How hard can it be?

It should be trivial to make them many thousands of times faster.

Not really. You're limited to the speed of the individual chips and the number of parallel storage lanes. They also target the 2.5" SATA market because it gives them an immediate in. Directly into new desktops and systems without consuming a slot the high performance people who would buy these are likely shoving an excess of games into. The high end is already using those slots for storage.

Believe me, the industry -is- looking into ways of getting SSDs on to faster buses, but it takes time and some significant rearchitecture. Also, NAND sucks ass, with high block failure rates fresh out of the fab outweighed by sheer density. And it's only going to get worse as lithography gets smaller.

The controller chip has a heat sink, because it's designed for performance, not power efficiency!

No, it's because the thing's running an Xilinx Virtex5 FPGA. It also costs a ton as it's using 96GB of SLC NAND, and is part of a fairly modular design that is reused in the io-drive Duo and io-drive Quad.

Today, we still have SSDs that are slower that mechanical drives at some tasks

If you're referring to the older JMicron drives that failed utterly at 4K random reads/writes, then you're mistaken. That was the case of a shit controller being exposed. Even the Indilinx controllers, which paled next to the Intel chip, outclassed mechanical drives at the same task.

on the other hand we have FusionIO, a company with technically great products that decided to try to target the consumer market by releasing a tiny 80GB drive for a jaw-dropping $1500. I mean.. seriously... what?

If you think that's bad, consider that the Virtex5 they're using on it costs on the order of $500 for the chip itself. You linked the "pro" model, which supports multiple devices in the same system in some fashion. You want this one, which is only $900. Both models use MLC NAND, and neither are really intended for mass-market buyers (you can't boot from them, after all.)

- We included some early C300 results with the benches. The C300 will read faster (sequentially) under SATA 6Gb/sec, but it is simply not as in most other usage.
- Fusion-IO - good luck using that for your OS (not bootable). Fast storage is, for many, useless unless you can boot from it.
