Compact Flash cards
So far the cheapest cards from Kingston with Lifetime warranties run about $75 for 32GB. I am actually planning on getting a couple of these to retire one hdd that I have had in service for backups the past 3 years or so. Temp Ranges are generally -25C to 85C and are waterproof. So with the offsite backups I am using through DataStorageUnit.com and what is in my machine should be more than sufficient. I have one of the 25N1 multi slot readers so I can pretty much read any media I want. SD cards seem to be just about as durable, at least a close 2nd, but about the same price. I wouldn't look at any USB flash drives because I literally have had 2-3 in the past few months fall apart in my hands. With my data on it. Another lets not make me a happy camper issue. As far as compact flash goes I really haven't seen any 64 GB cards that at present would be in the price of us mortal humans. Right now that 32 GB would fit what I think is critical to backups and in the next 6 months, most likely after the holidays prices should drop on 64GB sufficiently. The idea is compactness, durability not necessarily size of the drive at present. Does anyone else use anything else that I may not be thinking of at the moment? -- -- Remember it's not that we have something to hide, we just have nothing we want to show. ---Keep tunnelling. --- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
Re: Compact Flash cards
CompactFlash cards have the advantage of being an IDE interface, so it only takes a very simple (i.e. cheap) adapter to plug one into a motherboard IDE connector. For large capacity, I'd wait a bit with SD, as the SDXC cards and peripherals are just showing up, and there's a big improvement in headroom from SDHC to SDXC. If you want something internal, there are actual 2.5 SATA SSD drives in the 32G range on NewEgg for about $75 as well. gm5729 wrote: So far the cheapest cards from Kingston with Lifetime warranties run about $75 for 32GB.

Re: Compact Flash cards
This will be for actual backup purposes. I have an SSD/GPT already for my OS in my box. This is so I can carry and go. SDXC is $275 for 64GB, a little more than I want to spend at present, but a future contender for sure. I have no IDE slots on my mobo, its all SATA. Welcome to the world of Micro ATX. Which by the by for those that don't know. gdisk and gnu Parted are the only partitions you can use on SSD/GPT drives or you destroy the block/geometry mappings. There are no such thing as logical/extended partitions on them, everything is primary. YOU MUST after setting the GPT mapping for the MBR set up a min 1MB empty partition, no filesystem, flagged as bios_grub or ee, kinda like the 82/83 schema. GRUB 2 is best on these devices and grub.org recommends strongly using a separate /boot, be prepared with a Super Grub2 Disk just in case. After that you are set as normal with your favorite distro. -- -- Remember it's not that we have something to hide, we just have nothing we want to show. ---Keep tunnelling. --- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss

What does GPT mean? The SSD should not care about what partitioning tool is used. So, at the moment, I am confused about your statements above. Maybe I don't understand something.

Re: Compact Flash cards
GPT disk A GPT disk uses the GUID partition table (GPT) disk partitioning system. A GPT disk offers these benefits: • Allows up to 128 primary partitions. (MBR disks can support up to four primary partitions and an infinite number of partitions inside an extended partition.) • Allows a much larger volume size - greater than 2 TB, which is the limit for MBR disks. • Provides greater reliability due to replication and cyclical redundancy check (CRC) protection of the partition table. • Can be used as a storage volume on all x64-based platforms. -- -- Remember it's not that we have something to hide, we just have nothing we want to show. ---Keep tunnelling. --- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss

Very interesting. Thank you. You stated: gdisk and gnu Parted are the only partitions you can use on SSD/GPT drives or you destroy the block/geometry mappings. Is the destruction of the geometry mappings a bug in other tools or a side effect of using GPT or what? I'm trying to understand how the drive would allow an outside tool to muck about in it's mapping data. In general, such data is simply not available to outside tools.

Yes I did. cfdisk and fdisk will ruin the mappings on the drive. I have found with most installers that upon ELF trying to boot there is a GPT error and the installer won't let you continue. IF you can continue and you use the above tools in their present state you will probably in the very strongly realm get instabilities. If you add such things as LVM2, RAID, etc etc they can increase. In my case and this has taken me 6 months to figure out along with someone who is developing a hybrid iso/usb installer. My MBR got overwritten by the /boot partition by 2 bytes. Doesn't sound like much, until you install a bootloader and it overwrites the /boot partition by that 2 bytes. Now if your computer is having a bad day, which in this case it is you might not be able to boot or you might have no /boot. So I would encourage using the proper tools so as not get surprises in your xmas stocking. vp -- -- Remember it's not that we have something to hide, we just have nothing we want to show. ---Keep tunnelling. --- PLUG-discuss mailing list - PLUG-discuss@lists.plug.phoenix.az.us To subscribe, unsubscribe, or to change your mail settings: http://lists.PLUG.phoenix.az.us/mailman/listinfo/plug-discuss
