TR5M-B ESATA Storage By Robert Mcgeorge I was searching for a fast and efficient way to manage large volumes of files and this seemed to be pretty much what I needed. I have tested the Thermal take Dual Esata/USB Hard Drive array and they did not say anything about needing a HBA card that is explicitly for multiporting. Works in JBOD or RAID with USB. Only reads one hard drive in ESATA if you do not have a multiport HBA (Host Bus Adapter) Card. All computers right now do not come with a multiport Esata HBA installed even the ones with two ESATA Ports. I have tried the Linksys Dual Network Attached Storage NAS-200 and found it to be very slow at data transfers but very reliable when you have it like you want it. The good thing about the TR5M-B setup is that it comes with the multiport card. Use it! It works! I tried first setting up the unit without the included software. All JBOD.Findings Pro: It found my two hard drives (Seagate 1.5Tb and 500 GB)that I installed with data already on the hard drive. I was able to access the data.Findings Con: The transfer rates in this setup (Straight Pass Through-No manufacturer software installed) were pretty slow. 30 to 60 Megabytes per second.With manufacturer software installed:Findings Pro: I took the data on the two hard drives and backed it all up. Then I installed the manufacturer software and configured for JBOD again with that same software. The transfer rates were 100 to 200 Megabytes per second. This is the same speed as transferring between two internal hard drives on your computer. Use the Software!Findings Con: Transferring Between the TR5M-B Hard Disk #1 and TR5M-B Hard Disk #2 were pretty slow, about 30 Megabytes per second. This is due to it having to go through the same multiport HBA card for data transferring. (Tunnel Effect)Use it for transferring from your computer on-board hard drives to the TR5M-B drives or visa-versa(same transfer rates). Try not to transfer between the hard drives within the TR5M-B!Some day this will be ancient stuff...hmmmm maybe in about 5 years.Bottom line: It works for storing data and not having to spend over a $1000 bucks. Buy your hard drives as your pocket book can handle it. So far I am looking at installing all 1.5Tb hard drives due to the fact they are still 7200rpm and about $114 at Bestbuy. When the 2Tb hard drives go to $100 and 7200rpm then I will look into them. 5 of 5 people found the following review helpful. Great unit By John S. Dean I needed an array so I could hang it off a windows home server and store all my dvd's. This one little unit replaced two large 200 disc DVD changers I used to hang off my media center computer, under my TV. I only threw 6 TB of disks on it for the time being, but it works to hold all my digital media - saved TV captures, AVI files, MP3's, photos, files, backups, and about 650 movies now.Setup was a snap, discs are easy to get in and out, and since it's in my basement, even if the unit had been noisy it wouldn't have bothered me, but it's not.Great way to get some disk storage for your digital content. 1 of 1 people found the following review helpful. Great for archiving backups By Prodigal Knot These are terrific little disk enclosures. They are a little noisy for desktop use, but I use them as archival backups of data on my SAN. The price of large capacity disks is so reasonable now, there is no excuse to use tape anymore.I have a total of 6 2TB units that I keep my working backups on. Since I need to have a fail-over that will work quickly, these backups are essentially replicated copies of the exact files and file structure on my SAN. With a single 4 port 300Mbps SATA card on any server or workstation I can have a completely functional backup for my 6TB worth of document images from my SAN. Performance is a slight issue as the disks I use on these backup disk arrays are set up as RAID-5 using the Silicon Image Java
