Might be a stupid question but......
In the reviews I have read on this drive they only mention using it in a laptop. Can you use it in a full size desktop pc?
It's most likely slower than a desktop drive well unless your whole OS can fit in 4GB. But yes it will fit in a desktop with a 2.5inch to 3.5inch adapter or other suitable mounting rails.
its 500GB hybrid drive with 4GB flash onboard. real world test shows it to be just a tad slower then a ssd from reviews i read. synthetic benchmarks shows it to be faster then a regular desktop drive.
None of the reviews I've seen mention anything about using this as a game drive. Would this drive perform better in gaming vs. a conventional HDD?
I've got one of these on my test box. Anyone want any specific tests done?
Just had a 2 hour sit down with my Seagate rep.... she was unable to ansear alot of my questions though im sending the engineering department an email here tonight and should have a responce early next week... Any questions anyone wants me to ask? Ill take a list for the next few hours and i can include the results.
Biggest one i have is "How will defragmenting effect the 'frequently' used algorithem" and how big is the "frequently used algorithem"'s memory.... 3 years down the road on a heavily used drive will it crash when the memory fills up?
those are just a couple that I have... and im sure you guys must have a load, so lemme have em.
See if you can get the to explain to you how the cache works. When is it updated. Since there is no write caching it must be doing it in the background. What is the trigger? I'm surprised they are being so secretive with this. If you had some details (like with the Silverstone HDD boost) you can figure out its weaknesses and strengths so that you can determine if you can live with the trade-offs.
Some of these questions were answered during the Seagate webcast. If the flash dies then the drive will act like a 7200 rpm drive. Defragmentating will work, since there is no write caching the it will just by-pass the cache. The only thing that could happen is that if a block is written frequently as part of the defrag then it might get transferred to the cache. From what I've heard so far, this is my guess of how the cache works.
1) The HDD controller tracks which blocks are being loaded from the computer. Since you only have 32MB DRAM they can't be tracking the data itself, most likely the blocks in a look-up table.
2) If the block is read 2-3 times the algorithm recognizes this as a frequently accessed block and starts the process of transferring the block into the NAND cache.
3) Now as new files are loaded from the drive a compare happens to see if the data is in the cache. This means that if there is no cache hit the read access will be slower than a regular drive. You can see this in some of the benchmarks where the initial runs are slower than a 7200rpm drive.
4) The table must be kept in RAM for speed purposes and save to NAND at shutdown and reloaded on power-on. So a portion of the 32MB ram must be reserved for this. The question is how much and does this make the DRAM cache more comparable to standard drives.
