Tonight, the first of the final ten episodes of SGU will air on SyFy. I’m looking forward to and dreading it simultaneously. The door is closed on SGU continuing somewhere other than SyFy, though there is the possibility of a movie or two like the original Stargate series managed to pull off.
I’ve got the storage system all sorted out now. Here’s my disk manager:
Disk0 (E: – BACKUP) is the 2TB Western Digital Caviar Green, formatted as one large basic volume. Disk 1 and Disk 2 are the 1TB Samsung Spinpoints, where the first 128 GB of each have been striped together to create a single 256 GB striped volume (Y: – FASTDATA) and the latter 800 GB are mirrored (Z: – USERDATA). There’s also a strange unallocated block on one of the Spinpoints, which is relatively tiny (130 MB). Odd, that. Finally, Disk3 is the 128 GB Crucial RealSSD C300. I’ve moved all the user data directories to the mirrored partition and kept the Windows OS and application data on the SSD, with plenty of room to spare.
I was curious as to the performance of the striped volume versus the SSD. Note that I allocated the beginning of the spinpoints to the stripe, to “short-stroke” it (ie, the data is on the start of the disks, meaning the read heads have to travel less physical distance). Unfortunately, HD Tune does not seem to like partitions, only treats disks as single entities, so I used CrystalDiskMark 3.01 instead. The results were intriguing! Here are the runs for each partition – each run had 4 averages, 1000MB test data size:
2TB Western Digital Caviar Green 800GB mirrored partition, Samsung Spinpoint F3 (pair) 128 GB Crucial RealSSD C300 256GB striped partition (short-stroke), Samsung Spinpoint F3 (pair)
What is kind of amazing is that in sequential reads, the striped volume actually matches the SSD in read speed, and outperforms by a factor of 2 on write! However, when it comes to random 512K and 4K sectors, the SSD completely smokes the striped volume. This suggests that the striped volume would be just as good as an SSD for things like video other multimedia. In fact I might just rename my striped volume VIDEO and move the My Video folder to there instead of on USERDATA. Actually I should rename USERDATA just DATA as well 🙂
I’m not really sure why I created the striped volume, other than simply because I could. I didnt need a full terabyte for mirroring once the OS and apps are excluded. At some point in the future i can move to 2TB disks if necessary, but this setup shuold last me for a few years at minimum, if not longer – especially since I’m also segregating video. The only downside is that the striped volume not only lacks redundancy, it’s doubly vulnerable to disk failure. But that’s why I have my backup volume E, after all, and backblaze. (Though backblaze doesn’t backup data files over a certain size… need to check into that)
I’ve put a huge amount of overthought into this, but I think I am finally happy with how it all turned out. I need to do my final wrap up post on PREFECT now, with photos and cost estimate. Since the only game I run is WoW I think I am basically futureproof for a long time.
Christopher Nolan is doing the third Batman film, and some plot spoilers are starting to leak around the web. What intrigued me however was how Nolan has tapped Tom Hardy and Joseph Gordon-Levitt in supporting (and antagonistic, if not villainous) roles. The rivalry between their characters in Inception was one of that film’s strengths and I am interested to see them both on screen together again.
I need to go through my statements to verify this. But it troubles me that the agent can give me wrong information about my account, requiring that I correct him with an actual copy of my latest bill. If I hadn’t insisted, I’d have been seriously misled. (more…)
stacked against a hard drivethe size of a credit card
For a few moments, I was confused enough to wonder if I’d accidentally ordered the 1.8″ drive size instead of the 2.5″. It’s not only small, it’s unbelievably lightweight. It comes with a nifty little SATA-to-USB adapter for cloning software to it prior to installation.
I’m really keen on doing a fresh install of Win 7 x64, but I also want to move my data off the boot drive, and make the data drive a mirrored volume (as I mentioned earlier, I bought two Spinpoint 1TB drives). So, here’s my order of operations:
1. install one 1TB spinpoint drive, formatting as two partitions, one 128 GB to match the SSD, the second as 872 GB for the data partition. I’m not exactly sure why I am creating the smaller partition, but it seemed logical, if you will pardon the pun. These will be Y: (SPARE) and Z: (USERDATA).
2. move the My Documents folder (and My Videos, My Music, etc) to USERDATA. This is a lot simpler than trying to move the system folders.
3. now, the original boot drive should only have about 30 GB left (just OS and apps). Clone this to the SSD using the included software and the cable that came with the SSD.
4. replace the boot drive (a 1 TB Seagate) with the SSD and boot up in full SSD glory. Re-run Windows Experience Index to bask in the glory of 7s. If all goes well, take the old boot drive back to Best Buy.
5. Add the second Spinpoint and mirror using Windows software RAID rather than the built-in motherboard variety (which is referred to disparagingly at various online forums as “fake RAID” because it still relies on the PC’s CPU to do most of the work.)
At this point I will have a BOOT partition in C: (128 GB SSD), a BACKUP partition in E: (2 TB Caviar Green), a USERDATA partition in Z: (870 GB mirrored Spinpoints) and a spare partition in Y: (128 GB which I might actually do short-stroke striping across the spinpoints just for fun, rather than a simple mirror. I might reserve that for video). There’s also the external 1 TB drive and Backblaze for redundancy.
I’ll update the post with my earlier hard drive benchmarks from HD Tune and the new one from the SSD for comparison once I’ve got it all in place…
UPDATE – here’s the benchmarks from the various drives using HDTune. The Samsung is actually the older one I had, which seemed to have issues and was returned to Amazon. I replaced it with the Seagate, and now have taken the Seagate back to Best Buy in favor of the SSD and the new pair of Spinpoints (the new spinpoints are not benchmarked yet but should be identical).
Also note the huge difference in the SSD performance between SATA 2 and 3 modes. The latter requires me to sacrifice the bandwidth to the PCI x16 slot however, so I need to test framerates in WoW in both configs (SATA 2, PCI-E x16 vs SATA 3, PCI-E x8) to see which is better overall. Even in SATA 2 mode, the SSD is a beast.
