Pros: I like the 5k color spectrum and is what I wanted anyway.
It's a good thing it has this nice beefy ceramic heatsink which fwiw it does get hot after being on a while; anything thinner would of been too hot and surly the electronics in the bulb would be eventually compromised.
I like the heatsink on this, I wish my brand TCP 60 watt LED's had this same heatsink because they need it since with the cheap heatsink they use it still gets way too hot! and so I choose Rosewill over TCP for this very reason!
Cons: Out of 7 bulbs 2 are 1 second delay turn on, but the rest are instant on. This is fine if you use all the same timings on the same switch meaning they will all come on at the same time, otherwise I'll put the 1 second delay together, or alone, and no big deal.
Other Thoughts: Going forward, Rosewill should get Engineering and Production together and get these LED's to all be created with the same turn-on timing.
I still give this bulb a 5 star though, well made, nice quality, and again an appropriate beefy heatsink for it's 60 watt supply
Pros: Last month I bought 12 of these ROSEWILL "Cool White" 40 watt LED's
...anyway after coming back a month later to write a review I see this new review from the last poster saying that the LED fluctuates or something. I don't see any of that happening at all.
We use the 40 watt Cool White' bulbs and we like it for over bathroom mirror which that fixture holds 3 of these; perfect cool white color for the bathroom.
Also in an enclosed ceiling kitchen fixture which the "Cool While" is perfect for that too; otherwise we use warm white for the living room, etc
If I notice any of the mentioned fluctuation though I will come back and speak of it for sure; but we just haven't seen that happen.
Cons: All good
Other Thoughts: Anyway excellent deal for these that day I bought 12 of these ROSEWILL "Cool White" 40 watt LED's on Sale! for $3.99 ea + 6.47 SH which equals .53 ea for shipping ..sure I would of liked free shipping :)
Great LED Bulb for a great sale price.
Pros: It's better than I expected actually because I didn't think it would transfer this fast via USB3.0
Copying a 8 GB single file from an internal Seagate 2 TB HD via USB 3 over to this Seagate 5TB drive, and watching the regular Windows 7 transfer rate gui box as it copied, stated off @ 200 but by the end of the copy leveled off at 135 MB/s ...and only took 50 seconds flat - now that is Excellent !
Yes as others have asked, this 5 TB is only a 5900 RPM, but as others knowledgeable have also commented it really doesn't equate to that much in reality for backup purposes.
For instance the above test was copying from a 2TB 7200 RPM drive to this 5 TB 5900 RPM and as stated it copied an 8 GB file @ minimum of 135 MB/s in just 50 seconds
Copying the same file in reverse back to where it came from (iow, onto a 7200 RPM) was @ a minimum of 160 MB/s in just 45 seconds.
As far as doing benchmarks I don't care so much since it's real-time data transfer rates as I've done above is what matters and is what I go by.
Looking at this drives specification via HD Tune Pro shows it's:
Supports UDMA Mode 6
Mu use of this drive is only when needed
I don't plan on installing any of the software it gives, my only purpose is to use this occasionally, plugging it in only when needed, to copy backup large partition image files too, or anything else I want, but then unplug it and store it somewhere else.
Running everything with a modern i7 setup. My OS used was just Windows 7 installed on a 128 GB SSD, also running a Seagate 2 TB (ST2000DM001) as an internal backup along with it. All has run flawless for over a year now.
Cons: None that I can think of, for my specific usage.
I bought this 5 TB on sale for only $139
My 2 TB on sale was only $59
Other Thoughts: Instead of buying a 10 TB when it comes out at high $ value, I'm going to buy more 5 TB units on sale, since having the off-chance safety using multiple units is better than all on one.
I was going to take this out of the case an install it as an internal, but I don't see the need to now, since my internal 2 TB via SATA 3 doesn't write backups any faster than this 5 TB via USB 3.0, and so there's no gain with my stated intent of usage, which is only to plug this unit in for occasional backup and then store it elsewhere for safety.
For running OS's, well it's a no-brainer - nothing is faster than using an SSD
