Introduction, Design Performance (Part I)
These days, you’ll find clearly unconstrained kinds of solid-state drives (SSDs) for sale, from high-end PCI Express add-in cards that are so rapid they need feverishness sinks, to drives a distance of a hang of resin that container into little M.2 ports on new motherboards and slim laptops. You’ve also got SSDs that use opposite forms of memory, including multi-level dungeon (MLC) and triple-level dungeon (TLC) NAND flash, as good as SSDs with increasingly cavernous capacities, interjection to a rising ability to smoke-stack dies vertically, one atop a other. (See a examination of a 4TB Samsung SSD 850 EVO.)
When we demeanour by this lens of “an SSD for any form of consumer,” we can see a logic behind Toshiba’s new entry-level SSD, a OCZ TL100. This is an SSD that’s about as simple as it gets, designed essentially for people looking to ascent from a tough drive, who usually need a decent solid-state replacement. The OCZ TL100 is Serial ATA-based (which means it can be a plug-in deputy for any complicated 2.5-inch tough drive), and it’s accessible in usually dual capacities: 120GB and 240GB.
What’s unequivocally constrained with this drive, though, is a pricing: It’s flattering tighten to rock-bottom.
At this writing, a 120GB OCZ TL100 expostulate was offered for $50, and a 240GB for $70. That’s usually about a lowest cost tier during any ability we’ve seen for any SSD that’s not on sale or noted down to make room for an incoming deputy model. You can find other SSDs utterly nearby this cost range, however, so a Toshiba OCZ TL100 isn’t all by a lonesome—SSDs such as a SanDisk SSD Plus, PNY CS1311ADATA Premier SP550Crucial MX300OCZ Trion 150 sell for roughly a same cost during their relating capacities. However, Toshiba is anticipating that a possess code name (the association has now subsumed a OCZ name as an SSD sub-brand) and glorious guaranty module will tempt shoppers to select a indication over a competition.
Not surprisingly, a OCZ TL100 resides during a bottom of Toshiba’s OCZ-branded SSD stack, usually subsequent a Toshiba OCZ TR150 (how Toshiba now refers to a Trion 150), and both those drives use Toshiba TLC NAND modules to store data. TLC is a form of memory that’s intensely fitting in a low-cost SSD marketplace due to a “good enough” altogether opening and affordable pricing. It has turn a de facto customary memory form for entry-level and even many midrange SSDs over a past few years, ever given Samsung initial brought a tech to marketplace with a SSD 840 EVO. Though Samsung and Micron/Crucial have given brought an even more technologically modernized TLC memory to a market, in a form of “3D” or plumb built NAND dies, a TLC NAND in a OCZ TL100 is good, out-of-date planar TLC, that means a dies are laid down in one craft plane.
That’s expected during slightest one reason why, as we wrote above, a OCZ TL100 is accessible only in a dual little capacities of 120GB and 240GB. The drive’s rated specs are fundamentally as quick as a Serial ATA interface allows, during slightest when it comes to sequential-read and -write speeds. For reads, a OCZ TL100 is designed to broach adult to 550MB per second, and for writes it’s rated for 530MB per second. So ubiquitous opening shouldn’t be a regard (at slightest in theory) with these drives, or any late-model SSD, for that matter.
The usually area where these drives could be deliberate “low spec” is their continuation ratings, yet that tag unequivocally usually relates to a 120GB drive, that is rated for 30TB of write endurance. Still, Toshiba records on a Web site that this grade of continuation translates to 27GB of writes any singular day, via a drive’s three-year guaranty period, that is a heck of a lot for a normal consumer to shake through.
That said, we have, personally, been means to surpass that many movement on an SSD in usually dual years, yet we are also energy users relying heavily on a complement for work and play. 30TB should be sufficient for more-casual users. The 240GB expostulate is rated to hoop adult to 60TB of writes, that is 54GB of writes per day. We doubt anybody would be means to surpass that turn of activity within a drive’s three-year guaranty period, unless you’re regulating this expostulate in some kind of server. Just like a Nissan Versa isn’t built to contest in a Indianapolis 500, a Toshiba OCZ TL100 isn’t built for a severe final of 24/7 multi-user access.
Toshiba offers this expostulate with a Advanced Warranty Program, that is designed to streamline a “my expostulate has unsuccessful and we need a new one” process. Instead of watchful for we to send a expostulate behind to a association before determining if a problems are lonesome underneath guaranty (which, of course, costs we downtime, and maybe income if a expostulate is in your categorical work PC), Toshiba says it will usually boat we a new expostulate along with a lapse tag right away, should we have a problem. Though we’ve never had to make use of this sold program, it’s a scold proceed to hoop expostulate RMAs. We have had to continue a customary form of lapse process, and it’s a hulk pain in the…ahem…boot waiting dual weeks yet a expostulate usually to find out if a builder will send we a replacement.
The usually other “feature” value deliberating with these simple drives is that they embody better-than-average software, deftly named “SSD Utility,” that we can use to guard a expostulate and perform certain functions, such as a triggering a primer trim authority or a secure-erase. We’ve lonesome this module countless times in a past, so we won’t dwell on it here. If you’re meddlesome in a outline of a SSD Utility details, check out a Software territory of a examination of a Toshiba OCZ RD400 drive.
Performance (Part I)
If you’re new to a universe of SSDs, a few things are value observant when it comes to performance.
For starters: If you’re upgrading from a customary spinning tough drive, any complicated SSD will be a outrageous improvement, speeding adult foot times and creation programs launch faster. Today’s high-end 2.5-inch SSDs make use of a specific interface, SATA 3.0 (also called “6Gbps SATA”), to grasp limit speed contra older, yet still common, SATA 2 ports, that tip out during 300MB per second. We exam all a SSDs on a SATA 3.0-equipped test-bed PC to uncover their full opening abilities. To get a many speed probable from complicated drives, you’ll need a complement with SATA 3.0 capability, as well.
If your complement is formed on an Intel chipset after than those ancillary 2nd-Generation “Sandy Bridge” processors (or one of a newer AMD chipsets), your laptop or desktop substantially has this interface. Be certain before buying, though. If your complement is creaky and doesn’t have SATA 3.0 support, there’s little indicate in profitable a reward for a expostulate with a limit probable performance. SATA 3.0-capable drives will work usually excellent with previous-generation SATA ports, and there’s meagre reason to compensate additional for expostulate speed that your complement can’t take advantage of. Any simple stream SSD will work usually as well, in that SATA 3.0-less scenario.
PCMark 7 (Secondary Storage Test)
The Secondary Storage Test is a subtest underneath Futuremark’s incomparable PCMark 7 benchmarking suite. It employs a opposite proceed to expostulate contrast than pristine speed tests like AS-SSD, that we’ll get to next. PCMark 7 runs a array of scripted tasks standard of bland PC operation and hoop accesses. It measures app launches, video-conversion tasks, picture import, and more. The outcome is a exclusive numeric score; a aloft a number, a better.
This measure is useful in gauging ubiquitous opening contra other drives. Note that we secure-erase all SSDs before using PCMark 7’s Secondary Storage Test.
Right off a bat, we can see usually how “entry level” this SSD is—it placed during a really bottom of a benchmark chart, despite not by a whole lot. Still: Ouch. It’s formidable to parse a accurate reason for a bad showing, given we don’t inspect a relapse of all a particular tests that were run to grasp this total score, yet we’re certain we’ll find out some-more information in a remaining tests.
AS-SSD (Sequential Read Write Speeds)
The benchmark application AS-SSD was designed privately to exam SSDs (as against to normal tough drives). This environment within AS-SSD measures a drive’s ability to review and write vast files. Drive makers mostly quote these speeds, as a fanciful maximum, on a wrapping or in advertising.
Sequential speeds are critical if you’re operative with really vast files for picture or video editing, or we play lots of games with vast levels that take a enlarged time to bucket with normal tough drives. We secure-erase all SSDs before using this test.
The Toshiba OCZ TL100 hold a possess in a initial straight-line test, averaging 503.7MB per second. This is not utterly a limit volume of bandwidth authorised by a SATA interface, yet it’s close. Generally speaking, many complicated drives can strike around 500MB per second these days, so we’ll rate a OCZ TL100’s opening here as “acceptable.”
TLC drives are famous for carrying “write issues,” in that they mostly can't means high write speeds possibly for a enlarged duration of time, or for really vast files. In these situations, their aegis eventually gets full, and when it does, we get to see a “real” write speed of TLC flash, that generally ain’t pretty.
That doesn’t utterly seem to be a box in this test. But regardless, a OCZ TL100 ranked second-to-last in a benchmark draft of new SATA drives. It wasn’t delayed adequate to be shocking—446MB per second is still decent—but contra a competitors a OCZ TL100 is slower, obviously.
AS-SSD (4K Read Write Speeds)
This test, also a partial of a SSD-centric AS-SSD benchmark, measures a drive’s ability to trade little files. Often overlooked, 4K performance, utterly 4K write performance, is critical when you’re articulate about foot speed and module launch times.
When booting adult your complement or rising programs, many little files get accessed and edited frequently. The faster your expostulate can write and review these kinds of files (especially energetic couple library, or DLL, files in Windows), a faster your OS will “feel.” Since these little files are accessed many some-more mostly than vast media or game-level files, an SSD’s display on this exam will have a larger impact on how quick it feels in typical use.
Stop a presses! The OCZ TL100 was means to outperform roughly any other SATA expostulate we’ve tested in this benchmark of little review commands. Its measure of 42.4MB per second was quick adequate for a series dual container on a scoreboard, creation it seem like a really efficient SSD for daily OS duties.
Though a OCZ TL100 achieved utterly good in a review apportionment of this test, a same can't be pronounced for a write portion, as it ranked as a second-slowest expostulate we’ve tested recently. To a credit, a OCZ TL100 places alongside many other totally excusable drives, including a higher-end Toshiba OCZ VX500Crucial MX300, and the WD Blue SSD so it’s during slightest in decent company.
