Rating: 4/5 Performed well, noisier than original December 7, 2017 I actually just took this drive out of my iMac and went back to the original 1tb drive. It made a constant noise that I thought was the fan over-spinning because of the OWC sensor kit cable not working. But the sensor was probably fine, the fans were spinning at the right speed, and when I took the drive out and put it into an external case (where it now will live forever....) I distinctly heard its whisping sounds of the drive spinning. So, if you want a good drive for performance for a tower under your desk, this is the a good choice. But not for an iMac right next to your ears.

Rating: 5/5 Fast and reliable December 11, 2016 I was being inundated with external drive enclosures, so I completely changed my backup/storage strategy. I now use OWC Mercury Elite Pro Dual enclosures which let me remove drives when they are full, store them in "naked" form, and replace them with new drives. I've purchased eight of these Toshiba drives, recommended by OWC as among the most reliable and very fast. My experience to date has been exactly that. There are cheaper drives, but the cost of a failed drive is infinitely greater than the few extra bucks these require.

Rating: 5/5 Fast, meets rated capacity, good value March 14, 2016 The idea of purchasing 5 TB of fast, reliable hard drive space for around $200 is mind boggling to me. My first hard drive held 18 megabytes, drew 250 watts from the w all socket (in its large enclosure) and cost $3,000! I guess that lets you know it was round 1981 when I bought it. Still, the amount of storage available in a small, low-power package is truly amazing, and this drive is a great buy.

Rating: 4/5 Nice drive, but not the most silent one March 5, 2016 I use this drive for my Time Machine backups since last July. No complaints when it comes to its performance. The amount of space is fantastic. It is however not a silent drive by any means. The fact that It sits in a Mercury Elite Pro enclosure may not help to reduce the noise level. I would have given 5 stars if it wouldn't be so loud.

Rating: 3/5 this a fair product October 29, 2015 Power mac G4 1.25 GB mirror door 2003 and TOSHIBA 5TB drive and Sonnet Serial ATA PCI card This product works in mac os x 10.4.11 and mac os x 10.5.8 but it have problems reading 2TB drives in mac os 9.2.2 because it too big. The product crashed and unmounted in mac os x. Then I reformat drive again in mac os 9.2.2 and found out only reads 2TB in mac os 9.2.2. The drive works in directly in mac os 9.2.2 and mac os x 10.5.8 but not in mac os x 10.4.11 because it unmounted the drive in this system. You need to change the product description only reads 2TB in mac os 9.2.2.

This review is from 5.0TB Toshiba MD04ACA Series 3.5-inch SATA 6.0Gb/s 7200RPM Hard Drive.

Response from MacSales.com, Technical Support November 2, 2015 That's actually a limitation of the OS - not the drive itself. OS 9.2.2 won't recognize any drive capacity over 2.2TB. You can however set aside a partition of less than 2.2TB for your OS 9 needs and then a separate partition for your more recent OS.

Rating: 5/5 This product has brought new life... October 20, 2015 This product has brought new life to my iMac! Before installation of this new hard drive, I had to shut off all incoming e-mail, I couldn't do any updates, nor, could I do anything that required any memory whatsoever! The instructions were dead on with the exception of the following: Before you decide to upgrade your Mac, be sure to have your copy of the OS disc or else you will be screwed... Lucky for me, I had mine, and with a little more research I was able to do the upgrade without a hitch.
